Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating green onions and a film locking device, and more particularly to a method for cultivating green onions, which uses a mulch film made of a light-shielding film to soften the root side of the green onions. Also, the present invention relates to a film stopper used for softening by lifting a mulch film used in this cultivation method.

[0002]

2. Description of the Related Art Green onions used for food must be softened, especially on the root side. If the root part is not softened, the commercial value will be extremely low and it will not be edible. When cultivating green onions by conventional open field cultivation, soil is applied to the green onions from both sides in 3 to 5 times with a hoe or a mulcher, and 20 to 40 cm is applied to the root side by utilizing the light shielding property of the coated soil. Has achieved softening.

When it is difficult to soften the soil, rice husks are used in place of the soil, and a method of shading the rice husks has been developed.

[0004]

In the softening of green onions by soil application, the width of the ridge must be 80 to 100 cm in order to attract the soil, and a wide space must be provided between the ridges. There are drawbacks. In addition, there is a problem that high quality soft white onions cannot be cultivated unless they have a soil quality that does not easily collapse due to soil gathering. Furthermore, there was a problem that the roots were damaged in order to soil the soil, and the growth was stagnated by this, and the pathogenic bacteria entered from the cut roots. In addition, since the planting groove was deeply dug and transplanted for the purpose of reducing soil gathering work, the planting method was not suitable for direct sowing because it was easy to encounter moisture damage.

In view of these problems, a cultivation method has been developed in which a polymer film intended for softening is used to perform lightening while shielding light. However, such a conventional method has a drawback that it takes a lot of time to cover the soft white film, and the green onion falls or bends when the wind blows. Further, since the adhesion of the polymer film is poor, there is a problem that soft white unevenness is likely to occur.

When an office clip is used to improve the adhesiveness of a polymer film for softening white, the unevenness of softening white is reduced, but the width of the clip is wider than necessary, which causes a problem of bending onions. If the stagnation prevention tape and the soft white film are sandwiched together, the green onion will have a mark of the tape, which will lead to deterioration of the quality of the green onion. Also, if the onion lodging tape and soft white film are sandwiched together when unevenness occurs in the growth of the green onion, the new leaves of the poorly growing green onion are pressed by the lodging prevention tape, causing the onions to grow in a strained manner. , Will promote the bending of green onions. If the fall prevention tape is tied to the column, it will take a lot of work time and the onion will be easily damaged during the work. Further, the softening by the polymer film causes a problem in the weeding work during cultivation.

The method using rice husks instead of the polymer film requires a large amount of rice husks,
Not only is the storage place necessary, but there is a problem in the post-treatment of the rice husk after use. In addition, softening with rice husk is not suitable for stable direct cultivation of green onions. As described above, the conventional softening technique that replaces soil gathering is not necessarily completed, and there is a problem that a stable and efficient cultivation method cannot be established.

An object of the present invention is to solve the above problems and to provide a method for cultivating high quality soft white onion which is easy to cultivate and a film locking device used for the method. It is a thing.

[0009]

[Means for Solving the Problems] The first aspect of the present invention is to use a green onion with a mulch film having a length from the position where the green onions are planted to the tip end side in the direction orthogonal to the ridges is longer than the length required for softening the green onions. Laying along the ridges to be planted, while cultivating multi-scallions with the multi-film, when the green onions grew to a predetermined size, lifted the multi-film and covered the root side of the green onions to a predetermined height. The present invention relates to a method for cultivating green onions, characterized in that the mulch film is locked by a locking means in this state to perform softening.

A second invention is the same as the first invention,
Stands or locking means are set up along the ridge at predetermined intervals, and the onions are pressed from both sides by the locking means attached to the supporting pillars or the locking means themselves, The present invention relates to a method for cultivating green onions, characterized in that a suitable number of green onions are divided and held by a frame formed by a support or locking means and the string-shaped body.

According to a third aspect of the present invention, a fitting portion that is fitted to a pillar that is erected at predetermined intervals along a ridge and a fitting portion that is continuously fitted to the fitting portion and is in contact with the outer surface of the pillar. The present invention relates to a film locking tool that has a claw for sandwiching and locking a cord-like body, and holds the multi-film in a raised state by the string-shaped body locked by the claw.

According to a fourth aspect of the invention, a storage portion for storing the multi-film or the string-like body is provided at one end, and the entrance portion of the storage section is provided with a sandwiching portion for sandwiching the film or the string-like body. The present invention relates to a film locking tool that is configured and has a bent portion that is bent in a substantially U shape at the other end.

A fifth aspect of the present invention is to provide a pillar having a length equal to or longer than a length for softening the green onion, which is erected on the ridge, and which is provided at the upper end of the pillar and which sandwiches the green onion from both sides. The present invention relates to a film locking device, which has a storage part for storing a pair of cord-shaped bodies to be held by and which includes partitioning means for partitioning a green onion planted at a predetermined position of a ridge.

[0014]

According to the first aspect of the present invention, mulch cultivation is performed by the mulch film laid in the early stage of the growth of green onions. Such multi-cultivation prevents evaporation of soil moisture and runoff of fertilizer. In addition, the light-shielding property of mulch film causes herbicidal action, and creates a good soil environment that accelerates early growth of green onions.

Since the mulch film for cultivating such mulch has a width more than the length which requires soft white of the green onion, the mulch is lifted to cover the mulch film and the light is emitted at the height covered. The green onion is softened only by the height covered without passing it through. Further, since the mulch film is laid in advance, it is only necessary to lift this film, and the work of installing the soft white film can be omitted.

According to the second aspect of the present invention, the green onions that are planted in stripes along the ridges are formed by the columns or locking means and the cord-like bodies on both sides at appropriate intervals and at appropriate heights. It can be surrounded by a frame to prevent the onions from bending or falling over. In addition, since the outer leaves are in direct contact with the cords in order to enclose them at regular intervals, the cords do not directly contact the new leaves, which have the greatest effect on the growth of green onions, and this hinders growth. There is no.

According to the third aspect of the invention, since the claws are arranged to contact the outer surface of the supporting column to sandwich the string-shaped body, the string-shaped body can be attached to the supporting column without winding the string-shaped body around the supporting column. It can be locked simply by sandwiching it between the contacting nails, and the string-shaped body can be locked without damaging the onion, and the working time is shortened. Further, the positions of the claws can be made constant, which makes it possible to lock and hold the string-like body at a constant height.

According to the fourth aspect of the invention, the film or the cord-like body can be easily introduced into the storage portion by the clamping force of the clamping portion of the locking tool. Further, the film or the string-shaped body sandwiched in the storage portion spreads in the storage portion, and resistance is increased by the sandwiching force of the sandwiching portion, which makes it difficult to come off. By introducing the string-shaped body sandwiching the green onions from both sides into the storage part by opening the sandwiching part, the string-shaped bodies on both sides are joined at that position to easily partition the green onions. The U-shaped bent portion formed at the other end of the locking tool serves as a pinch of the locking tool, and facilitates the pinching work.

According to the fifth aspect of the invention, since the pair of cord-shaped members for holding the green onions from both sides are held by the storage portion, the interval between the cord-shaped members becomes constant, and the new onion Green onions can be grown without bending the leaves or falling over without damaging the leaves. Further, by adjusting the insertion amount when inserting the support pillar of the locking tool, the inserted string-shaped body or the multi-film can maintain a constant height. A frame body surrounding the green onion at an appropriate interval can be constituted by the pair of cord-like bodies housed in the housing portion and the partitioning means, and the enclosure is fixed by inserting the pillar into the ground.

Further, in such a locking tool, when the mulch film is sandwiched between the cord-shaped bodies introduced into the storage portion, a force is exerted on the cord-shaped bodies to prevent the onions from spreading laterally. This brings the effect that the stopped film becomes more difficult to come off. Moreover, by dividing the pair of cord-like bodies housed in the housing portion into right and left at appropriate intervals, only the multifilm is in strong contact with the green onions, and the extension of the green onions is not hindered more than necessary.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. Light-shielding rate of 99.9% and reflectance of 65% either before or after transplanting or direct-seeding onions.

According to the method for cultivating green onions using such a mulch film 12, the film 1 for mulch cultivation
Since No. 2 can be diverted as it is to a film for softening green onions, it is economical and has good working efficiency. Moreover, according to such a cultivation method, since the root of the onion can be cultivated without damaging the onion root due to the work factor, the occurrence of the disease due to the invasion of the soil disease fungus is eliminated. Further, the mulch film 12 makes the soil water uniform, suppresses the evaporation of water more than necessary, and prevents the soil from hardening, so that the root of the green onion becomes particularly vigorous, and the growth is quick and the evenness is good. In addition, unlike the conventional method, there is no need to dig deep into the groove to transplant green onions, and since it can be cultivated on flat ridges or high ridges as in conventional vegetable cultivation, there is no risk of moisture damage and it can be cultivated without choosing a place. You can do it.

In addition, according to the cultivation method using such a mulch film 12, the soil environment is improved, so that direct seeding cultivation, which was conventionally unsuitable, can be stabilized. Both stagnation and growth stagnation due to soil removal have disappeared, and the number of cultivation days is 40 to 6
It can be shortened by 0 days. Further, depending on the type of the film 12 used for mulching cultivation, it is possible to easily obtain a more suitable soil temperature and temperature during soft white cultivation. For example, when sowing in the summer when the soil temperature is high and harvesting in the winter, by using a film in which the reflectance on the front and back sides is different from each other and the reflectance on the front side is 65% or more and the reflectance on the back side is 45% or less, It is possible to cultivate mulch with the surface with high reflectance upwards and to cover the green onions with the surface with low reflectance outside. In this way, it becomes easy to prevent high ground temperature in summer and to compensate for insufficient temperature in winter.

Such a cultivation method can
Since the onions can be enclosed at regular intervals by using 6 and the locking device 37, the onions can be bent,
It is possible to prevent the person from falling down in advance, and the effect is further improved by frequently using the string 16 in multiple stages.

Fitting type locking tool 2 that can be freely fitted onto the column 20
Since the cords 1 and 26 are attached to the required height, it is not necessary to wind the string 16 around the support column 20, and it can be used as a guide for the coating height. Therefore, the working time can be significantly reduced. Further, the coating height of the film 12 lifted for softening becomes constant, the position of the string 16 is prevented from being displaced due to the shaking of the onion 11, and the height can be easily maintained.

When the locking tool 37 is used when the mulch film 12 is used for softening, the cord 16 can be divided into right and left by the storage portion 41 or the partition portion 40, and the cord 16 can be used to remove the onion 11 more than necessary. It is possible to correct the green onions 11 with a proper spread without damaging them, and to grow the green onions without damaging the new leaves. In addition, the diameter of the support column 20 is appropriately thin, and the mulch film 12 is sandwiched between the scallions with a suitable length, so the adhesion between the scallions 11 and the mulch film 12 is improved, and the inside of the scallions 11 is improved. High quality soft white onions can be cultivated with no sunlight coming in and clear boundaries between soft white and green areas. Further, since the pillar 38 is inserted into the soil along the outside of the film 12, the fluttering of the film 12 is less due to the pressing action of the pillar 38, and the pressing of the film 12 is not necessary. It becomes easy to maintain the height of the stop, and the onions 11 along the struts 38 of the locking device 37 are straightened to be straightened by bending the ridges 10 in the direction of the ridges 10. become able to.

Further, a locking tool 37 having such a column is provided.
Since the string 16 can be hooked on the sandwiching portion 42 and the support 38 can be inserted into the soil for use, the rolling of the string 16 and the bending of the green onion 11 in the ridge direction are reduced. Further, when the mulch film 12 is covered, the pre-installed locking device 37 with a post is used, so that it is possible to perform an efficient work without moving between the large onions 11 many times. .

Furthermore, in order to correct the looseness of the mulch film 12 lifted due to the softness immediately before harvesting,
By sandwiching with the locking tool 31, the soft white onion 11 is further homogenized, the boundary between the soft white part and the green part becomes clear, and high quality soft white onion can be cultivated. Also, in order to sandwich the mulch film 12 with a narrow width, the green onion 1 by the locking tool 31
The bend of 1 is not promoted.

In addition, in the method of softening green onions using such a multi-film 12, since the multi-film 12 having good elongation is used, the hardness of the multi-film 12 does not hinder the extension of the green onions 11 and the onions. It can be adhered and the quality of soft white is further improved. In addition, the cord 1 is attached to the fitting type locking tool 21.
Since 6 and the mulch film 12 can be sandwiched together, the height when the mulch film 12 is lifted and the workability of the locking work are improved.

As shown in FIG. 10, the mulch film 12 is cultivated in advance by stacking two mulch films, and the upper and lower mulch films 12 are lifted up to cover the roots of the left and right green onions 11, so that the spacing between the green onions is 1 /. It becomes 2 to 1/3, and it becomes possible to harvest the onion 11 with a harvest amount of 2 to 3 times that of the conventional cultivation method.
