Description

  The present invention relates to a method for growing plants by vegetative propagation.

  When a plant is propagated by vegetative propagation and rooting is difficult by cutting or the like, a cutting method may be used. By using the trapping method, seedlings can be obtained from the plant body.

  FIGS. 10A to 10D schematically show an example of the tree taking method. In this method, first, as shown in FIG. 10A, the bark is shaved from the trunk of the plant 21 and a part of the branch 22. And as shown in FIG.10 (b), the part 23 which shaved the bark is covered with the wet water sachet 24 grade | etc.,. After a while, as shown in FIG. 10C, roots 25 grow from the portion 23 where the bark has been cut. When the root 25 grows to some extent, a part including the root 25 is separated from the main body 21 of the plant as a seedling 26 as shown in FIG.

  FIGS. 11A to 11C schematically show another example of the trapping method. This method is a method in which a part of a branch is buried in the ground and rooted, and is also referred to as a claw method. In this method, first, a portion of the bark of the branch 32 of the plant 31 is shaved. And as shown to Fig.11 (a), it is buried in the soil as a state where it lie down sideways, bending a branch. Thus, when buried in the soil, after a while, as shown in FIG. 11B, roots 35 grow from the portion 34 where the bark has been cut. When the root 35 grows to some extent, as shown in FIG. 11C, a part including the root 35 is cut from the branch (plant body) 32 to form a seedling 36.

Patent Document 1 discloses a method of taking a seedling from a branch of an adult tree. In this method, first, an annular base is peeled off at an arbitrary width. Several cuts are made at an arbitrary length in the formation layer between the leather and the wood part in the direction of the tip from the cut end on the tip side of the annular peel. The skin is scraped off so that the formation layer is exposed in the vertical direction at a part of the root of the root prepared in advance, and the tip is scraped off at an acute angle, and the root is inserted into the notch of the branch. The outer periphery of the skin is fixed with tape or the like at a position where the branch formation layer and the root formation layer overlap. The whole root is hardened in a dumpling form with clay soil, and a dry cloth and a plastic bag are used to prevent drying. After confirming that the inserted roots and branches are settled, the wood part of the tip portion of the cut end is cut off. This method is used when grafting roots of different species.

  In fruit trees such as apples, there is a demand to grow trees having good properties by asexual propagation (vegetative propagation). At this time, there is a demand for a plant propagation method (asexual propagation method, vegetative propagation method) that can produce more seedlings efficiently, for example, in a single operation.

  The method shown in FIG. 10 is time consuming and the reproduction efficiency is not good. For this reason, when it is desired to produce more seedlings in one operation, it is not very suitable.

  The method shown in FIG. 11 requires a vast land (field) to bury the branches in the soil. In addition, since the branches are buried in the soil, they are susceptible to soil diseases such as root cancer disease.

  According to one embodiment of the present invention, a young seedling is planted sideways in a container separated from the ground so that a trunk is exposed (a step of planting sideways), and a plurality of new treetops are developed after the seedling has grown. Covering with a soil (step of covering with soil) and, after rooting from a plurality of shoots or the trunks in the vicinity thereof, separating each of the shoots or the trunks in the vicinity thereof (steps of detaching). , Plant propagation methods (asexual propagation method, vegetative propagation method).

  In many cases, when a plant is in a horizontal posture, a new treetop grows upward due to the action of plant hormones and the like. In this method, young seedlings are planted sideways in a container separated from the ground so that the trunk is exposed. For this reason, a plurality of new treetops can be sprouted (germinated) from the seedling. In addition, after a plurality of shoots have grown to some extent, a plurality of roots can be rooted from the shoots and / or trunks in the vicinity thereof by covering the bases of the plurality of shoots with soil. Then, after a plurality of roots are rooted from a plurality of shoots and / or the vicinity thereof, a plurality of seedlings are obtained by cutting off the plurality of shoots or the trunks in the vicinity thereof in a state including the shoots and the roots. be able to.

  According to this method, since seedlings are used instead of obtaining the seedlings from the branches and trunks of the plant body, it is easy to plant the seedlings sideways so that the trunks are exposed. By doing so, a plurality of seedlings can be produced in one operation. Furthermore, since it is a young seedling, it can be easily planted horizontally or in a state close to it in a container separated from the ground. By planting young seedlings in a container separated from the ground, it is possible to prevent morbidity of soil diseases such as root cancer. In addition, since it is planted in a container separated from the ground, it is possible to use sterilized soil or the like for the growth (cultivation) of seedlings, and soil diseases can be further suppressed. Moreover, since it can be planted in a container separated from the ground, it does not require vast land. For example, it can be grown (cultivated) in a house, etc. Can be. According to this method, it is possible to grow a plurality of seedlings while maintaining aseptic conditions and controlling the temperature in a house or the like as desired.

In growth process of the plant, as the container comprises a first container portion and second container portion, and the first container portion and second container portion Ru with those laterally adjacent . The first container part and the second container part may be integrated or separate. In this case, in the step of planting sideways, the root part of the seedling is put in the first container part, and the trunk part of the seedling is passed through the first container part and the second container part sideways to the second container part. It is preferable to include putting soil into the first container part.

  In addition, this plant propagation method is suitable for the growth of deciduous trees, particularly deciduous fruit trees. In this plant propagation method, in the step of planting horizontally, seedlings that are dormant in deciduous trees can be used as young seedlings. As the young seedling, a deciduous fruit tree seedling may be used. An example of a deciduous fruit tree seedling is an apple seedling. In order to obtain a dormant seedling that is not limited to the winter season, a dormant seedling that is dormant in a low-temperature environment such as a refrigerator may be obtained.

  Furthermore, according to this plant propagation method, the method may further include setting up a container in which a young seedling is planted sideways in a house and growing it (growing step). By heating the inside of the house to an appropriate temperature, the new tree can be spawned earlier.

  Another aspect of the invention is a system for growing plants. In this system, a root portion of a seedling can be inserted, and a first container part having an opening or a cut through which a seedling trunk part penetrates in a side wall, and an opening or incision through which a seedling trunk part penetrates a side wall A second container part that is laterally adjacent to the first container part, wherein the seedling trunk portion is disposed laterally in the second container part, and the seedling is placed in the first container part. And a second container part that can be planted.

  For example, by using this system, the plant propagation method as described above can be realized with a simple configuration. That is, more seedlings can be produced in one operation.

  In this system, it is preferable that a plurality of openings are provided in the bottom wall of the second container portion. The drainage of the trunk part of the seedling where new treetops grow can be improved.

  In this system, the first container part and the second container part may be integrated or separate. When the first container part and the second container part are separate bodies, an example of the first container part is a soft resin pot, and an example of the second container part is a flat seedling box. .

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing each configuration of a plant growth system 100 (see FIG. 3) according to an embodiment of the present invention. 1A shows the seedling 1, FIG. 1B shows the first container part 11, and FIG. 1C shows the second container part 12. The system 100 includes a container 10 for planting the seedling 1 sideways. In this example, the container 10 includes the separated first container part 11 and the second container part 12, but may be an integrated container.

  As the seedling 1, prepare a disease-free one. Further, in this example, a seedling 1 that is obtained by contacting a root 1b of another plant with a trunk 1a (grafting) is used. The code | symbol 1c in Fig.1 (a) has shown the graft part. Such a seedling 1 can be prepared using, for example, the technique described in Patent Document 1. The seedling 1 may be a seedling having a self root. Specifically, in this example, two seedlings of dormant apples (deciduous fruit trees) that have fallen in a low-temperature environment such as winter are prepared as the seedlings 1. In FIG. 1 (a), only one seedling 1 is shown. In this system 100, the number of seedlings 1 grown in the container 10 may be one, or three or more. Moreover, when preparing the dormant seedling (seedling) 1, the seedling (seedling) 1 may be placed in an apparatus capable of realizing a low-temperature environment of the refrigerator to be artificially brought into a low temperature state and allowed to sleep.

  The container 10 includes two first container parts 11 and one second container part 12. The two first container parts 11 and the one second container part 12 are separate from each other. Further, since the two first container parts 11 have the same shape, only one first container part 11 is shown in FIG. What is necessary is just to prepare the 1st container part 11 by the number of the prepared seedlings 1, for example. Although depending on the size of the first container part 11, a plurality of seedlings 1 may be planted in the first container part 11. Moreover, the 1st container part 11 and the 2nd container part 12 may be integral. Further, the container 10 of the present example includes a first container part 11 and a second container part 12 and is separated from the ground. However, the container 10 may be separated from the ground by a sheet or the like. Good.

  Specifically, as the first container portion 11, as shown in FIG. 1 (b), soft resin pots (polypots) each having a size into which the root portion 1 b of the seedling 1 can be inserted are used. be able to. A cut 11a is formed in a part of the side wall (peripheral wall) of the first container part 11, for example, in the central part or the upper part. The cut 11a is formed in a size that allows the trunk portion 1a of the seedling 1 to penetrate therethrough. The first container part 11 may be replaced with the notch 11a and may be formed with an opening having a size capable of penetrating the trunk part 1a of the seedling 1.

  Moreover, as the 2nd container part 12, as shown in FIG.1 (c), the flat nursery box (horticulture flat) is used. In the second container portion 12, two openings 12a through which the trunk portions 1a of the two seedlings 1 pass are formed in the side wall. The second container portion 12 may be replaced with the opening 12a and may be formed with a notch having a size capable of penetrating the trunk portion 1a of the seedling 1. The 2nd container part 12 is formed in the magnitude | size which can arrange | position the trunk part 1a of the two young seedlings 1 along the bottom wall of this 2nd container part 12 in the horizontal direction substantially in parallel mutually. . In order to improve drainage, the bottom wall of the second container portion 12 has a mesh shape or a mesh shape, and is provided with a plurality of openings 12b. When the size of the second container portion 12 is determined in advance, it is desirable to use the seedling 1 grown to a length that can be accommodated in the container 12. This is because the longer the trunk portion 1a of the young seedling 1, the higher the possibility of obtaining many new shoots.

  Moreover, in this example, compared with the height of the 1st container part (polypot) 11, the 2nd container part (nursery seedling box) 12 is low in height. In order to accommodate the trunk portion 1a of the seedling 1 planted in the first container portion 11 sideways in the second container portion 12, the second container portion 12 is provided with a height adjustment member. A table 13 is provided. The stand 13 can use a seedling box having the same shape as the seedling box used for the second container portion 12. That is, the stand 13 is arranged so that the seedling box is opened downward, and the upper wall (the portion that becomes the bottom wall in the second container portion 12) has a mesh shape or a mesh shape. The air flow is good, and when the soil is put in later, an environment with good drainage is formed.

  Next, a method for growing the apple seedling (young seedling) 1 of this example will be described. FIG. 2 shows a state in which the seedlings 1 are planted in the first container portion 11 so that the trunk is exposed sideways so as to be exposed. FIG. 3 shows a state in which the seedling 1 is planted sideways (substantially in the horizontal direction) in the first container portion 11, and the trunk portion 1 a of the seedling 1 is placed sideways in the second container portion 12. FIG. 4 shows a state where a plurality of shoots 2 have grown from the seedling 1. FIG. 5 shows a state in which a plurality of shoots 2 that have grown from the seedling 1 have grown to a predetermined size. FIG. 6 shows a state in which the bases of a plurality of shoots 2 that have grown to a predetermined size are covered with soil 20. FIG. 7 shows a state in which a plurality of roots 3 have grown from the seedling 1. FIG. 8 shows a state where a plurality of shoots 2 are separated from the seedlings 1 after rooting. FIG. 9 shows a state where a plurality of separated new treetops 2 are planted in a polypot 9.

  In the propagation method of the apple seedling (young seedling) 1 of this example, first, the seedling 1 is placed so that the root part 1b enters the first container part 11 and the trunk part 1a is exposed to the outside. The trunk portion 1a is passed through the notch from the inside to the outside. Thereby, the young seedling 1 is arrange | positioned in the 1st container part 11 sideways. Then, as shown in FIG. 2, aseptic soil (for example, sterilized soil) 20 is placed in the first container portion 11 to fill the root portion 1 b of the seedling 1. By doing in this way, the seedling 1 planted sideways can be prepared in the container 10 separated from the ground so that the trunk portion 1a is exposed. Two seedlings 1 planted sideways in this way are prepared.

  Next, as shown in FIG. 3, the trunk portions 1 a of the two seedlings 1 are inserted into the second container portion 12 from the openings 12 a so as to be substantially parallel to each other, and are arranged sideways. Do (planting sideways). At this stage, the seedling 1 may be moved to the house and the seedling may be grown in a warm environment. At this stage, a known appropriate method for promoting germination of a new tree may be applied to the seedling 1 together.

  When the seedling 1 is placed sideways and grown in an appropriate temperature environment, a plurality of new treetops 2 appear due to the action of plant hormones and the like. By putting the young seedling 1 into the container 10 as described above, the young seedling 1 is placed sideways. Therefore, after a while in this state, a plurality of new treetops 2 germinate from the seedling 1 as shown in FIG. As shown in FIG. 5, when a plurality of shoots 2 generated from the seedling 1 have grown to a predetermined size, as shown in FIG. 6, aseptic soil (for example, disinfection) is placed inside the second container portion 12. Spent soil) 20 is placed, and the bases of the plurality of shoots 2 that have grown are covered with the soil 20 (step of covering with soil). When an apple seedling is used as the young seedling 1, an example of the timing at which the base of the new tree 2 is covered with the soil 20 is when the new tree 2 has grown about 10 cm.

  The base of the shoot 2 is covered with soil 20, and after a while, as shown in FIG. 7, a plurality of roots 3 emerge from the shoot 2 or its trunk. After rooting to some extent, as shown in FIG. 8, each new treetop 2 is separated from the seedling 1 while including the root 3. The plurality of shoots 2 may be separated by a trunk 1a in the vicinity thereof. For example, as shown in FIG. 9, a plurality of seedlings 8 obtained by separation are replanted and shipped in a polypot 9 or the like, or further grown and used as a young seedling to further grow a new treetop 2. can do.

  As described above, according to the plant propagation system 100 and the plant propagation method of the present example, a plurality of seedlings 8 can be produced in one (a series) of operations including planting young seedlings sideways. Furthermore, according to the plant growth system 100 and the plant growth method of the present example, since the seedling 1 is used instead of obtaining the seedling from the branch or trunk of the plant body, the seedling 8 is obtained by the container 10 separated from the ground. Easy to grow. Moreover, since the seedling 1 is planted in the container 10 separated from the ground, the aseptic condition can be maintained. Accordingly, it is possible to prevent morbidity of soil diseases such as root cancer disease. Moreover, since the seedling 1 is planted in the container 10 separated from the ground, disinfected soil or the like can be used for the growth (cultivation) of the seedling 8, and soil diseases can be further suppressed. Moreover, since the seedling 1 can be planted in the container 10 separated from the ground, a vast land is not required. For example, since it can be grown (cultivated) in a house or the like, germination of the new treetop 2 can be accelerated, and it is easy to manage because it is a young seedling, and problems such as withering are unlikely to occur because the seedling is planted.

  In addition, although the example which used the apple seedling as an example of the young seedling is shown above, other deciduous fruit trees, for example, peach, pear, plum, chestnut, strawberry, cherry, plum, blueberry, other berries, etc. It may be a seedling. It can be applied to other deciduous trees. Furthermore, it may be necessary to drop leaves or promote germination of new treetops by a known appropriate method, but the above method can also be applied to evergreen fruit trees.
