Description

[Detailed description of the invention] This invention relates to a method for cultivating deep-rooted green onions.

As is well known, the lower half of the leaf of deep-rooted green onion is a hollyhock sheath, and several leaves overlap in the same circular shape to form a soft white stem, and it is required to be long.

Soft white rhyo has been around since it was a seedling, but its length is short, and its leaves branch out from its upper end.

In general, when deep-rooted green onions are planted in a shallow shield, they are less susceptible to pests and diseases, grow better, and increase yield. After planting, each time a new mulberry sheath grows to a certain extent and a new mulberry sheath grows inside the original stem, and the branching point of the leaves rises, the plant is ground 2 to 5 times to reduce the length of the soft white stem. obtain. For this reason, conventionally, a trench with a depth of about 15 to 25 cm was made in the planting area, and the seedlings were planted shallowly at the bottom of the trench, and as they grew, the trench was filled with soil a little to cover the soil. The workers who dug next to the ditch raised the soil higher than the top of the ditch and harvested it. Therefore,
It is necessary to dig trenches during planting, and then to mulch soil several times during the growing season, which requires a great deal of labor and effort during the long growing period from planting to harvest. Therefore, the present invention has been developed by the inventors and others over many years with the aim of cultivating deep-rooted green onions that are sufficiently long and have soft white stems that are approximately uniform in length while drastically reducing the labor and labor required in the past. It was developed by the following, and will be explained below with reference to the drawings.

In the present invention, when planting green onion seedlings, the segment 1 approximately corresponding to the length of the soft white stem to be obtained in the planting area is buried vertically with the upper end 1' approximately on the ground surface. The inside surrounded by body 1 is excreted. The cylinder 1 may be made of any material such as a bamboo cylinder, a metal cylinder, a cardboard cylinder, or a synthetic resin.

Bamboo, metal, and synthetic resin can be used repeatedly, so they have some advantages, but as mentioned later, when they are planted, they gradually rot in the soil and maintain their shape for a certain period of time. After that, it loses its strength and collapses into soil. For example, if it is made of cardboard or made of plant fibers made by press-molding beet moss, there are other advantages. In the case of beet moss, it turns into compost and turns into compost. At the same time, it is more preferable because fertilizing ingredients can be added.Of course, the fertilizing ingredient may be added to the cardboard.The cross-sectional shape of the cylinder 1 is not limited to a cylindrical shape, and may be any polygonal shape. When installed underground, the entire circumference may be connected as long as it can withstand the earth pressure from the surrounding area, or it may be broken along one side as shown in the figure and the entire circumference may not be connected.

The inner diameter should be approximately 3 to 4 skins to maintain space around the onion seedlings, and the length should be approximately 15 to 35 skins, which corresponds to the length of the soft white stem of the onion when harvesting. Determined by the variety of onion being cultivated.

The removal from inside the cylinder 1 involves driving the cylinder into the ground, or pushing it into place, and then digging out the soil inside.
Alternatively, you can dig a mortar-shaped hole deep enough to fit the cylinder, stand the cylinder in the hole, and fill the space between the hole wall and the outer circumference of the cylinder with soil, or dig a hole in the green for a pin at a golf course. This is done by using a hole drill that simulates a hole that approximately matches the outer diameter and length of the cylinder using the same principle as the hole drill used to remove the cylinder, and then placing the cylinder approximately snugly into the hole formed with this hole drill. be able to. However, in the simplest form, the auxiliary tool 2 shown in FIG.
Equipped with a steel plate 4 whose outer diameter is slightly smaller than the inner diameter of the cylinder 1,
On the upper surface of the tsuba, there is an operation section 5 that is either integrated with the tetsugoshi 4 or separate.
Using an auxiliary odor that has Push in (Fig. 3), then pull the auxiliary odor upwards as shown by the arrow, remove the yomegahi from the cylinder, leave the cylinder on the ground, install the cylinder, and remove the soil all at once. . It should be noted that the metal strip 3 does not need to be threaded over the entire circumference of the upper end of the cylindrical body, but may be threaded only partially over the entire circumference of the upper end.
Then, the onion seedling 6 and a small amount of soil and rice husks are placed in the cylinder, and if necessary, a thin stick is inserted into the cylinder and the soil is lightly poked, thereby suppressing the roots of the seedling with a spatula and planting.

The green onion seedlings to be placed in the cylinder should be the length from the bottom of the white stalk 7 of the main pot to the tip of the straw.In other words, the height should be longer than the cylinder, optimally the height should be 1.5 steps or more than the cylinder. It is preferable that the leaf sheath part 8 extends upward on the original soft white stem 7, and the hollyhock sheath part 8
Wait for the boundary part 9 of the millet to grow until it reaches almost the upper end of the cylinder 1, and replace the space 10 around the soft white stem and the leaf sheath part 8 extending above it with the cylindrical body 11. Fill the inside of the cylinder with soil, remove the cylinder and fill it with soil, or push the surrounding soil to eliminate the space.

Of course, you can't force the space 1 to be filled with soil or push people from around it to eliminate the space, but if you remove the cylinder 1, the soil around the space 10 will naturally collapse and fill the space, so you can't just fill the cylinder. You can just pull it out.Also, in the case of cardboard or beet moss, the wall thickness of the cylinder should be determined appropriately, and the cylinder will remain in the soil while it grows after planting. If you maintain the shape of the seedling and keep the space 10 around the seedling, then it will collapse and become a culturist.
This eliminates the need for sampling and filling the soil with soil.
``After that, wait for the seedlings to grow completely before harvesting, but if necessary, you may call the mulberry seedlings a few times before harvesting. We planted the area at the boundary between the hollyhock pod and the hollyhock 9 by planting it at the point where it would be time-consuming to wait until the hollyhock pods have grown and fill it with soil.
Until it reaches the upper end of the cylinder 1, the cylinder maintains the shallow tank state at the time of planting, which provides sufficient oxygen supply and allows for good growth. The growing hollyhock pods are kept out of sunlight as much as possible, and then the space surrounded by the cylinder is replaced with soil to soften the white stems, resulting in soft white stems (original soft white stems) that are approximately equal to the length of the cylinder. By harvesting deep-rooted green onions with stems and new pods grown on top of the stems, high-quality deep-rooted green onions with no uneven length of soft white stems can be produced.

After planting, as the roots grow, the roots at the lower end of the original soft white stem 7 will also extend, so a notch 1'' is formed at the lower end of the cylinder 1 so that the roots can extend in all directions from the outside of the cylinder. It is better to take a hawk.

If these notches 1'' are provided at both ends of the cylinder 1, the seedlings will be able to spread their roots outside the cylinder even if the whole body is placed in the ground with either end being the bottom end. This is convenient because if the notch is provided only at one end, there will be no mistake of installing the cylinder underground with the other end without the notch as the bottom end.Also, if the cylinder is made of beet moss, it is convenient. In this case, the beet moss can be passed through the wall of beet moss and stretched outside, so in this case it is not necessarily necessary to provide a notch.An embodiment of the present invention will be described below.

The cylindrical body was made by cutting a long vinyl chloride cylindrical pipe material with an inner diameter of 3.8 mm into 30 mm pieces.

The green onion seedlings were sown on March 28th, 48 days after germination, and the height from the root to the tip of the mulberry was about 45 skins.
Planting was carried out on the 5th. The variety is Kujo.

Pour the entire amount of fertilizer necessary for growth into the planting area, then create a ridge 12 with a width of about 50 mm and a height of about 40 mm, and cover the ridge with a mulching material 13 such as a black film or sheet to allow weeds to grow. and prevent fertilizer runoff.

Then, using the auxiliary device 2 shown in Fig. 2, mulch material 13
Cylindrical body 1 was placed in the ridge from above as described above, onion seedlings and a pinch of soil were placed inside the cylinder, and planting was completed.

On August 3rd, about 80 days after planting, the boundary between the leaf sheath and leaf blade protruded slightly from the upper end of the tube, so the tube was pulled out.

As a result, the original soft white stems and the new leaf sheaths extending above them were buried with the surrounding soil that had naturally collapsed. After that, the hollyhock pods buried in the soil are completely softened, and high-quality white onions with a length of 3 melon pods in the soft white part are harvested from early October to March of the following year. was completed.

In addition, since all the necessary fertilizer was applied during planting and mulching material was spread, there was no need to perform any cultivation management such as weeding until harvest.

Also, planting in high ridges improves drainage conditions. As described above, according to the present invention, it is possible to automatically manage soft white stems with a cylinder and produce deep-rooted green onions having soft white stems of a uniform, constant length without any effort, thereby saving labor in cultivating deep-rooted green onions. It has the excellent feature of being able to obtain high-quality products, and is good news for deep-rooted onion farmers.
