Description

Description: TECHNICAL FIELD [0001] The present invention relates to a cultivation method using seedlings grown in a container for raising seedlings. 2. Description of the Related Art When cultivating vegetables such as strawberries, tomatoes, and eggplants and various fruits, as shown in FIG. 8 , growing seedlings 92 in a cultivated soil 91 filled in a predetermined seedling growing container 90. When the seedlings 92 grow to an appropriate size, the seedlings 92 are taken out from the seedling raising container 90 together with the cultivated soil 91 (FIG. 8B), and are transferred to the cultivation area 93 and planted. The method is taken. When a seedling 92 is grown in a seedling container 90,
The roots 94 grown in the container are in a state where the cultivation soil 91 is involved. In this state, even when the seedlings are taken out of the seedling raising container 90, the portion of the root 94 in which the cultivation soil 91 is wound retains the shape of the seedling raising container 90, and this portion is called a root pot 95. [0004] During seedling period before planting is generally holding the seedling container 90 upright growing seedlings 92 is performed, seedlings 92 were taken out together with the soil 91 from seedling container 90, FIG. 8 (c ), The root pot 95 is set upright, or the root pot 95 is tilted as shown in FIG. In some cases, the seedlings 92 may be planted in the cultivation area while the seedlings 92 are in the seedling raising container 90 during the seedling raising period. It is planted in the cultivation area in a state. [0006] The present invention is to provide a case for planting seedlings 92 were grown in nursery container 90 to cultivation 93, and FIG. 8 (c)
As shown in, it is necessary to dig a relatively deep hole in order to bury the whole of the upright root pot 95 in the soil,
A great deal of effort and time is spent in drilling and filling the root hole 95 into the dug hole. Since the growth of the seedlings 29 increases as the capacity of the root mortar 95 increases, when growing seedlings having direct roots such as strawberries, the root mortar 95
Cultivation management is performed to make
As the length of 5 becomes longer, a deep hole must be dug during planting, so that the labor and time required for it are also increased. On the other hand, as shown in FIG. 8 (d), root ball 95
When planted in the cultivation area 93 in an inclined state, it can be planted in a hole shallower than the entire length of the root pot 95, so that labor for digging holes can be saved. However, the seedlings 92 after planting have the property of extending from a diagonal state to just above due to the action of auxin, which is a plant hormone. At this time, the seedlings 92 are subjected to stress. This stress may cause poor growth of the seedling 92. That is, when the root pot 95 is planted in the cultivation area 93 in an inclined state, there is a high possibility that engraftment becomes poor or the subsequent growth state becomes poor. Accordingly, an object of the present invention is to provide a cultivation method capable of saving labor for planting, achieving good survival after planting, and obtaining an excellent growth state thereafter. It is in. [0009] To solve the above object, according to an aspect of the present invention provides a cultivating method using a seedling which has been grown in a nursery containers, held in an inclined state a cylindrical nursery for the container To
After growing the seedlings to the extending direction of the stem of the seedling remembering angle in the axial direction of the root ball formed in the tubular nursery for the container by growing in the filled plug mixture, from the nursery container
The seedlings taken out together with the root pot, the growing period of the seedlings and
The planting method is characterized in that the seedlings of the seedlings are set in a cultivation area in a similar posture with the elongation direction of the stems substantially vertical. By adopting such a method, seedlings can be planted in the same posture as during the seedling raising period. , And the subsequent growth condition is also excellent. [0010] Since the direction of stem elongation and the axial direction of the root pot make an angle with this seedling, it can be planted in a shallower hole than a conventional seedling grown in an upright state. Therefore, it is not necessary to dig a deep hole in the cultivation area, so that the planting work can be saved, and the cultivation area with shallow soil can be coped with. The seedlings are grown in a cylindrical seedling raising container held in an inclined state , so that the stems of the seedlings extend upward from the opening of the container body, and the roots are held in an inclined state . Since the seedling grows and spreads over the entire cultivation soil accommodating part, a seedling in which the direction of extension of the stem and the axial direction of the root pot make an angle can be obtained. [0012] Such a seedling in which the direction of extension of the stem and the axial direction of the root pot make an angle can be grown using a conventional seedling growing container, but the opening of the container body is formed on the side wall of the container body. The seedlings can be grown using a seedling container that is inclined . When such a seedling raising container is used, it is possible to easily obtain a seedling in which the extending direction of the stem and the axial direction of the root pot are at an angle only by holding the seedling raising container in an inclined state , and Seedlings that are adapted to the type and planting conditions can be performed. In addition, as a method for obtaining seedlings in which the direction of stem elongation and the axial direction of the root pot are at an angle, seedlings being grown in a seedling growing container are irradiated with light from an oblique direction to stalk in the direction of light. Or a method in which the stem is bent to the leeward side by applying a gas flow in a certain direction. Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing a seedling raising process in the cultivation method of the first embodiment, and FIGS. 2 and 3 are longitudinal sectional views showing a planting process of a grown seedling. In this embodiment, as shown in FIG. 1, a seedling raising container 10 having a tapered cylindrical shape is fitted into an opening 12 formed in a holding device 11, and the entire holding device 11 is tilted so as to be tilted. Is held in an inclined state.
Then, the seedling 14 is filled with the soil 13 filled in the seedling container 10.
Is grown, and the root mortar 17 is formed. When the seedling raising container 10 is held in an inclined state,
Since the tip portion of the seedling 14 has the property of extending in the direction opposite to gravity, the seedling 14 in which the extending direction 15a of the stem 15 and the axial direction 17a of the root pot 17 make a certain angle can be obtained. The seedlings 14 thus obtained are taken out of the seedling raising container 10 together with the cultivation soil 13 as shown in FIG. 2 (FIG. 2A), and the extension direction 15a of the stem 15 is substantially vertical. Then, the whole of the root mortar 17 is buried in the soil ((b) in the same figure), so that it is planted in the cultivation area 19. The seedlings 14 in which the extending direction 15a of the stem 15 and the axial direction 17a of the root mortar 17 make a fixed angle can be planted in a shallower part of the soil than conventional upright seedlings. There is no need to dig a deep hole in the ground 19, and the planting work can be saved. After planting, the seedlings 14 and the root mortar 17 are maintained in the same posture as during the seedling raising period, so that they do not receive stress and the survival after planting is extremely good. Since the upper part of the stem 15 extends almost vertically upward as it is, the subsequent growth state is excellent. The extension direction 15a of the stem 15 and the root
The angle formed with the axial direction 17a is 90 degrees to 1 degree by changing the holding angle of the seedling raising container 10 during the seedling raising period.
Since it can be changed to 80 degrees, FIG.
As shown in (b) and (c), cultivation areas 21 and 21 to be planted regularly.
Seedlings 24, 25, 2 at angles corresponding to 2, 23 soil depths
6 can be obtained. That is, by changing the holding angle of the seedling raising container 10 during the seedling raising period, the seedling raising corresponding to various conditions such as the soil depth of the cultivation area and the type of the plant can be performed accurately. Next, with reference to FIG. 4, a description of a second embodiment of the present invention. As shown in FIG. 4, the flange 7
The seedling raising is performed using a tapered cylindrical seedling raising container 74 which is formed so that the cultivated soil accommodating portion 73 is inclined when 0 is in a horizontal state. When the seedling raising container 74 is fitted into the opening 72 formed in the horizontal holding device 71, the seedling raising container 74 is held in an inclined state. And cultivation soil storage part 7
When the seedling 75 is grown on the cultivated soil 13 filled in 3, the root pot 76 is formed. As a result, a seedling 75 is obtained in which the extension direction 78 of the stem 77 and the axial direction 79 of the root pot 76 make a fixed angle. Thereafter, the seedling 75 undergoes a process similar to that of FIG.
The plant seedling 75 can be planted in the cultivation area. For the same reason as in the case of the first embodiment, the seedling 75 after the planting is well-established, and the growth state thereafter is also excellent.
In addition, in the case of the seedling raising container 74 having such a shape, the area of the upper end portion of the container held by the holding device 71 is increased, so that there is an advantage that the holding state is stabilized. Further, since the opening area of the upper end is large, There is also an advantage that it is easy to supply water and fertilize. FIG. 5 is a view showing a third embodiment of the present invention.
Figure 4 nursery containers of similar shape as the seedling raising containers 74 80
Shows a state in which is locked to a locking wire 82 by a locking tool 81. In the case of the present embodiment, the same effect as in the case of the second embodiment is obtained. In the above embodiment, the root pots are taken out of the seedling raising container and planted. However, the seedlings can be planted together with the seedling container without being taken out of the seedling raising container. In this case, the same effect as described above can be obtained. Next, with reference to FIGS. 6 and 7, another embodiment will be described regarding nursery. In the embodiment shown in FIG. 6 , during the seedling raising period, the light source 43 irradiates light 44 in a certain direction to the seedlings 42 growing in the seedling raising container 40 held by the holding device 41. Thereby, the stem 42a of the seedling 42 becomes
It grows in a bent shape. Since the bending angle can be changed by changing the irradiation angle of the light 44, seedling raising corresponding to various planting conditions such as the soil depth of the cultivation area and the type of plant is possible. In this case, the seedling raising container 4
0 is held upright, and the seedling 42 in which the stem 42a is bent.
Therefore, during the seedling raising period, various operations such as watering, watering, and fertilizing can be performed without any trouble as before. In the embodiment shown in FIG. 7 , the seedlings 5 growing in the seedling container 50 held by the holding device 51 during the seedling raising period.
2, an airflow 54 in a certain direction is applied from a blower 53. As a result, the stem 52a of the seedling 52 grows in a U-shaped bend. Since the bending angle of the stem 52a can be changed by changing the air volume, the wind speed, etc. of the air flow 54 flowing from the blower 53, it is possible to perform seedling raising corresponding to various planting conditions such as the soil depth of the cultivation area and the type of plant. Can be. In addition, it is also possible to obtain a seedling 52 in which the stem 52a is bent by using an air flow from a hot air duct or the like instead of the blower 53. In any of the embodiments shown in FIGS. 6 and 7 , similarly to the seedling 14 shown in FIG. 1, it is possible to obtain a seedling in which the stem of the plant seedling and the axial direction of the root pot make a fixed angle. Therefore, by planting in accordance with the procedure shown in FIG. 2, the seedlings 42, 52 after planting are well-established, and the growth state after that is excellent, for the same reason as in the first and second embodiments described above. It will be. Even if the embodiment shown in FIGS. 6 and 7, a method for planting Remove the root ball from the nursery containers 40, 50 or seedling containers 40 and 50 Gotonae 42,
Any of the methods of planting 52 can be used. According to the present invention, the following effects can be obtained. (1) Seedlings are grown at an angle to the axial direction of the root pot with respect to the direction of extension of the stems of the seedlings. Since the seedlings can be planted in the same posture as during the nursery period,
After planting, the seedlings are not stressed and have good survival, the stems extend directly above, and the growth state thereafter is excellent. Also, since the extension direction of the stalk of the seedling and the axial direction of the root pot are at an angle, it is possible to plant in a relatively shallow hole, which can save labor for planting, and can be used in cultivation areas with shallow soil. Available. (2) By using a seedling container having a cylindrical cultivated soil storage part which can be held in an inclined state and an opening formed in a part of the side surface of the cultivated soil storage part, the stem of the seedling can be maintained. Since the roots extend directly upward from the opening and the roots spread and grow over the entire cultivated soil accommodating portion, seedlings in which the extending direction of the stem and the axial direction of the root pot make an angle can be relatively easily obtained. (3) By raising seedlings in a cylindrical seedling raising container held in an inclined state , the stems of the seedlings extend directly upward from the opening, and the roots are stored in a soil holding state held in an inclined state. Since the seedlings grow and spread over the entire part, seedlings in which the direction of extension of the stem and the axial direction of the root pot are at an angle can be obtained relatively easily. In addition, it is possible to obtain seedlings in which the direction of stem elongation and the axial direction of the root pot are at an angle using a conventional seedling raising container, and the angle can be changed simply by changing the holding angle of the seedling raising container. Therefore, it is possible to grow seedlings adapted to the type of plant, planting conditions, and the like.
