Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a cultivation device for long onions, and more particularly to a cultivation device for growing the soft white parts of long onions as long as possible.

(Prior art) Regarding the cultivation of long onions currently known, the technique for growing the soft white parts for a long time is disclosed in Japanese Utility Model Application Publication No. 112741/1983 (
1st precedent example), Japanese Utility Model Application Publication No. 59-59737 (second precedent example), and Japanese Patent Application Laid-Open No. 63-141518 (third precedent example).

All of the above-mentioned examples are superior in terms of workability and increased yield compared to the previous technique of mounding soil at the base of long onions and growing the soft white part, but they are described below. It has some problems.

In the first precedent example, a narrow space is formed between tunnel houses that are successively laid, and long onions are planted in this space, and rice husks are introduced to shade the stems of the long onions and soften them. Raw 0 copies
However, the problem is that the rice husk blocks out too much light and the soil temperature does not rise, which does not encourage growth and does not allow the harvest to grow.

The second precedent example has supports t) [
A light-shielding film is placed inside the branch office to create a soft white area, but the film is folded in the early stages, and as the child grows up, the film can be folded. However, since the work is carried out between the rows of plantings, the leaves break each time they are set and pulled up. Broken nests of long onions lead to temporary stagnation of growth, which is a problem that leads to late harvest and raking. Another problem is that it takes time to set the light-shielding film, and the workability is not good.

In the third precedent example, an air bag made of a light-blocking material is interposed between the planting rows of long onions, and Soft 11 part is grown here, but since one air bag is a light-blocking material, #! ! A rise in temperature cannot be expected, and this may be due to the problem of reduced yield, similar to the first precedent case. Since the rice husks are divided and thrown in at random, there was also a problem of breakage in the first example, and the first to third examples could not be said to be cultivation devices that can feed everything.

(Issue 171 or Problems to be Solved) The material for shading does not prevent the soil temperature from rising, the work of laying the material does not cause the nests of the green onions to break, and the workability of the work of laying the material is good. To provide a cultivation device capable of preventing overturning of long onions.

(Means for solving the problem) The actual method is to install air tubes between rows of long onion plantings in order to block light and prevent overturning of the long onion stems. ''-ㅅ is made of a light-shielding material on both sides that come in contact with the green onion, and the top and J1!! section are made of a transparent material. Multiple Toru 1■
The material was charged internally.

The third means is to protrude an adhesive margin on the side of the air tube 1 and the welding part with the main part, and also to provide a partition that connects the center part of the side member to the inner surface of the air tube 1. piece, it +'J
By doing so, when air is supplied to the air tube, the cross-sectional shape is as square as possible.

(effect) Lay air tubes between the rows of green onions.

To grow a long onion by supplying air into an air tube to prevent light blocking and overturning of the long onion stem.

(Example) A side member 2 along the planting row of air chives Q-bumen and long onions;
The side member 2 is divided into a top member 3 and a bottom member 4 placed in contact with both ends of the side member 2, and the side member 2 is made of light-shielding material C.
The top member 3 and the bottom member 4 are made of transparent IJlff material. The valley material is made of a plus deck film or sheet, and the side members 2 are, for example, a black film.

The four corners of the air tube 1 are bonded together by heat welding or the like, and in particular, the side members 2 and the top member 3 have an appropriate length δ.
The adhesive allowance 5 is extended.

Also, inside the air tubes 1 and 1 are respective side members 2.
A subsection 6 is provided in the center of the 1-bu to divide the inside of the 1-bu into an L lower chamber 7 and a lower chamber 8. The partition pieces 6 do not need to be provided over the entire length of the air tube 1, and may be formed intermittently. Further, an inner tube 9.9 made of a transparent material is inserted into the L chamber 7 and the lower chamber 8 which are divided by the partition piece 6.

In the embodiment, the air duvet iM is divided into two units, but it may also be divided into three units and an inner tube inserted into each chamber. Also, if the welding allowance 5 is formed at the joint between the top member 3 and the side member Z, or also at the joint between the bottom member 4 and the side member 2, the top and bottom can be ignored during use. It's convenient.

The air duplex 1 supplies air to the inner tube 9 housed therein to inflate it, but also supplies some air between the inner tube 9 and the air tube 1. Is the air tube l glued at the four corners? f. Since the partition piece 6 provided inside the center of the side member 2 controls the deflection of the center, the cross-sectional shape becomes as square as possible.

When the air tube 1 is inflated, the welding allowance 5 protrudes from the clearly rounded Fu 4 part and serves to make the cross-sectional shape of the tube closer to a square shape, and the welding allowance 5 comes into contact with the stem of the long onion. This serves to effectively block light from the stem.

Cultivation of long onions is carried out in the following order. Plant green onion seedlings in rows with evenly spaced apart. Insert the inner tube 9 into the air tube 1, remove the air, fold it or keep it in a rolled state, and then attach a string to the end, and pass this string between the rows when planting each green onion. Since nothing is laid in the field when the seedlings are planted, the field is not blocked from sunlight and can maintain the soil temperature necessary for the growth of green onions.

When the green onions grow and the stems are to be shaded, the string attached to the end of the air tube 1 is pulled and the air tube 1 is laid between the rows of plants. Next, air is supplied into the inner tube 9 to inflate the air tube 1. Further, a small amount of air is also supplied between the air tube 1 and the inner tube 9 if necessary.

When the air tube 1 is inflated, the side member 2 comes into close contact with the stem of the long onion from both sides and acts to block light from the stem, causing the stem to grow soft and white. On the other hand, since the top member 3 and the bottom member 4 are transparent, the temperature of the ground does not drop when the air tube 1 is inflated.

In addition, since the adhesive layer 5 contacts the stem and blocks sunlight from directly above, the boundary between the green leaf part and the soft white part becomes clear, similar to when the soft white part is grown with a mound of soil.

Once the green onions have grown completely, the air is removed from the air tube and the green onions are harvested.

(Effects of the Invention) The present invention consists of an air tube laid between rows of green onions planted with side members and top and bottom members, and the side members are made of a light-shielding material and the top and bottom parts are made of a light-shielding material. Since the member is made of a transparent material, when the air tube is inflated, it blocks light from the stem, but prevents a drop in the soil temperature in the field, promoting the growth of green onions and increasing the yield. In addition, since the air tubes can be laid without having to go between the rows of green onions, the workability of laying the air tubes is improved.

Furthermore, since the work of laying the air tubes can be done without the need for workers to enter between the rows of green onions, there is no chance of the leaves of the long onions breaking during the installation process, thus avoiding temporary growth stagnation. It can be expected that the harvest time will be secured and the yield will increase.

In addition, the cross-sectional shape of the air tube can be made as rectangular as possible by providing an adhesive margin at the joint between the partition piece that connects the side members and the top member and side member within the air tube. This makes it possible to completely shield the long onion stem from light and prevent it from overturning.

Furthermore, since a plurality of inner tubes are housed within the air tube, it has excellent durability.
