Description

  The present invention relates to a method for cultivating soft white onions and potatoes. More specifically, the present invention relates to a method for cultivating soft white onions and potatoes in which the number of cultivated trees per unit area is significantly greater than that of the conventional earth filling method.

Among the green onions, long green onions (hereinafter referred to as soft white green onions) that mainly eat the soft white portion of the leaf sheath (stem) are clearly distinguished from green leaves and white stems, and have a certain length or longer. Is preferred.
As a conventional method for cultivating soft white leek, there is a method of cultivating a stalk on the above-ground part and depositing a soil around the stalk. However, in this method, it is necessary to widen the space between the ridges for earthing, and the interval between the ridges is about 1 m, for example, and the number of cultivation per unit area is not large as a whole. Furthermore, the earth filling work and the harvesting work require a large amount of labor.
In addition, there are potatoes as crops that can be harvested on the ground, and there are similar problems.
The present inventor has previously proposed a method for cultivating soft white onions that can produce straight soft white onions, whose number of cultivation per unit area is about twice or more that of the conventional earth filling method, and whose stems are thick and long (patents) Reference 1). However, in this method, soft leek is cultivated while adding a filler such as soil in a seedling box or board enclosure that accommodates 1 kg of soft leek seedlings. The soil was usually used as a filler, which was about twice as much as the method, and it was accompanied by a large work effort, such as digging up and washing off the soil adhering to the crop.

JP 2013-66384 A

  The present invention has been made in view of the above circumstances, and provides a method for cultivating soft white onions and potatoes, in which the number of cultivated trees per unit area is significantly greater than that of the conventional soil filling method, and work labor such as harvesting is significantly reduced. It is intended to do.

In the cultivation method of the present invention, a soft white onion or potato, which is a crop that can be harvested in the above-ground portion of the earth, is grown while covering with a light filler in a field provided with a plate preventing leakage of the filler. It is something to harvest.
That is, the present invention
(1) Soft white onion or potato cultivation method for growing crops while covering with light filler, (i) Soft onion seedlings or potato seeds in a field provided with a plate preventing leakage of the filler Potatoes are planted in multiple rows between plants and rows where each crop has the necessary spacing for growth. (Ii) Immediately after planting in the case of potatoes, slightly growing in the case of soft white onions, a light filler is placed. A light filler layer is formed and fertilizer and water are applied. (Iii) After that, the light filler is added at least once in accordance with the growth of the crop, and the filler collapses as necessary. A method for cultivating soft white onions or potatoes, characterized by adding a prevention plate,
(2) The soft white onion or potato cultivation method according to the above (1), wherein the light filler is one or more of rice husk, sawdust, and expanded polystyrene particles,
(3) The method for cultivating soft white onions or potatoes according to the above (1) or (2), wherein the anti-spill collapsing material is a material that strikes a pile and attaches a horizontal plate.
(4) Soft green onion or potato cultivation method according to any one of the above (1) to (3), which is performed in house cultivation or in a vegetable factory building,
(5) The soft white onion or potato cultivation method according to any one of the above (1) to (3), which is carried out in open field cultivation,
(6) The method for cultivating soft white onions or potatoes according to (5) above, wherein the light filler layer is covered with soil with a thin thickness,
Is to provide.

The present invention relates to a light white filler such as rice husk, sawdust, foamed polystyrene particles, etc. Because it is grown and harvested with a cover, it is not necessary to have a wide space to fill the soil as in the conventional filling method, and it is sufficient to plant each crop with an interval necessary for growth. For this reason, the number of cultivated trees per unit area is significantly higher than that of the conventional fill method, and the number of cultivated trees per unit area can be 4 to 10 times that of the fill method with soft white onions and more than 3 times that of the fill method with potatoes. Become.
And since it grows while covering with light fillers such as rice husk, sawdust, and polystyrene foam particles, it is not necessary to do heavy labor for earth filling, and soft leek is easily pulled out from the top at harvest time It can be harvested and potatoes can be easily dug by hand. In any case, it is only necessary to wash off the light filler adhering to the place with water, and the work labor is greatly reduced.

FIG. 1 (a) is a plan view when four seedling boxes of soft white leek of 1 liter of Patent Document 1 are arranged, and FIG. 1 (b) is the same as 4 in FIG. 1 (a) in the present invention. It is a top view at the time of planting a seedling in the board enclosure of the same area as a seedling box for one piece. FIG. 2 (a) is a plan view of a case where four seedling boxes of soft white onions of 1 liter of Patent Document 1 are arranged side by side with a passage for maintenance being arranged, FIG. 2 (b). These are the top views at the time of planting a seedling in the board enclosure of the same area as (seedling box arrangement + maintenance passage) of Drawing 2 (a) in the present invention.

  The method for cultivating soft white onions and potatoes according to the present invention is a cultivation method in which a crop is grown while covering with a light filler, and (i) a soft white onion seedling is placed in a field provided with a prevention plate for preventing the leakage of the filler. Or potato seeds are planted in multiple rows between plants and rows where each crop is spaced as needed for growth. Fill the agent to form a light filler layer and apply fertilizer and water. (Iii) Then, in accordance with the growth of the crop, perform the operation of adding the light filler one or more times, and fill as necessary. It is characterized in that the agent leakage prevention plate is added.

The present invention is a method for cultivating soft white onions or potatoes, which is characterized by growing a crop while covering with a light filler, and may be open field cultivation, house cultivation or cultivation in a vegetable factory.
Therefore, first, it is necessary to provide an anti-spill collapsing plate around the field, in which soft leek seedlings or potato seeds are planted. As in the conventional method, no space for padding is required, and unlike the method of Patent Document 1, a seedling box for each row is not required. A plurality of rows can be planted, and the number of cultivated trees per unit area is significantly greater than that of the conventional earth filling method or the cultivating method of Patent Document 1.

There are several modes of the area surrounded by the plate that prevents the filler from collapsing as follows.
When planting and cultivating within reach of open-area cultivation, for example, as shown in FIG. 1, the seedling boxes for each ridge of Patent Document 1 are surrounded by the same area as that arranged in four rows (FIG. 1 (a)). In this case, soft white onion seedlings can be planted twice as many in the present invention (FIG. 1 (b)).
In addition, when the seedling boxes for each basket in Patent Document 1 are arranged in four rows and a passage for maintenance is provided (FIG. 2 (a)), when surrounded by the same area as (seedling box + passage), soft green onions In the present invention (FIG. 2B), the number of seedlings can be 3.25 times as many.
Furthermore, the enclosure can be of any size as long as it is within the reach of various ridges / nozzles (as will be described later).

The plate that prevents the filler from collapsing (plate enclosure) is piled up and a horizontal plate is attached. When the crop grows and the upper surface of the light filler layer is close to the upper end of the board enclosure, the board's horizontal board is added.
In addition, planting can be carried out after putting a bottom on the board enclosure (seedling box) and putting soil necessary for planting. If the seedling box is large enough to be moved, it can be moved. In this case, it is preferable that the bottom has several holes for drainage.

  “Plants are planted in multiple rows between rows and between rows where each crop has an interval necessary for growth” means that soft white onions are about 3 to 5 cm between the rows as usual, and about 3 to 10 cm between rows (corresponding to the conventional space) The potatoes are planted at about 25 cm between the stocks as usual and between the rows (corresponding to the conventional ridges) about 25 cm.

In the case of Fig. 2 (b), there are planted parts that are out of reach such as the central part, but the light filler does not bend the crop as if the soil was dropped even if dropped from the top of the crop. , Use "blower nozzle" and "suction nozzle" or "blower cylinder" and "suction cylinder" that can select the front and rear and left and right outlets to flatten the "feed bar" of light filler This makes it possible to perform work that is far beyond reach.
`` Feeder '' is equipped with a light filler reservoir at the top, and it is sent by tilting it by gravity, a method that uses the force of air blow by a blower or compressor, a pressure feeding method by a piston, screw pump, spiral pump, etc. Feed light filler into container (enclosure).
That is, regardless of whether it is open field cultivation, house cultivation, etc., as shown in FIG. be able to.

In the case of house cultivation, a filler spill prevention plate enclosure may be provided in the house, but the outer wall of the house may have a role as a filler spill prevention enclosure, and for maintenance purposes. When installing the passage in the house, make a wall that prevents the collapse of the filler with piles (pillars) and plates.
Even when there are no maintenance passages, the light filler after planting, fertilizer, and water are sprayed on the house through the house entrance (with a light filler leakage prevention plate) and windows. It can be performed from outside by operating a feed rod and various nozzles.
Moreover, in cultivation in the vegetable factory building, depending on the situation, one or two or more filler leakage prevention plate enclosures may be provided.

  As the light filler, rice husk, sawdust, and expanded polystyrene particles are preferable.

  In addition, in the case of outdoor cultivation, light filler may be scattered due to strong winds. To prevent this, it is necessary to cover the light filler and cover with soil or sand at a thickness of about 0.5 to 1 cm. Good. In this case, the harvesting work (pullability) is not significantly affected, but the crop at the time of harvesting is somewhat dirty due to the soil and sand. However, dirt is greatly improved compared to conventional soil cultivation.

After planting, immediately after planting in the case of potatoes, after a little growth in the case of soft white onions, with a light filler, the potato is about 15-20 cm thick, and the amount of soft white onions grown (about approx. A light filler layer is formed at a thickness of 5 to 10 cm), and fertilizer and water are provided.
After that, the potatoes are once again grown, and the fertilizer is applied during the period when the soil has been piled up, and then a light filler is deposited from above with a thickness of about 5 to 10 cm.
After the first light filler is put on the soft white onion, when the soft white portion grows about 5 to 10 cm, fertilizer is applied and then the light filler is put up to a thickness of about 5 to 10 cm from the top. Thereafter, whenever the soft white portion grows about 5 to 10 cm, the fertilizer application and the light filler are repeated from the top while adding the filler collapse prevention plate as necessary.
Water is sprayed as appropriate so that it does not dry in either case.

Harvesting can be done by pulling soft white onions easily from above, and potatoes can be easily dug by hand, greatly reducing labor and eliminating the need for machinery.
To clean the harvested crop, it is only necessary to wash off the light filler adhering to the place with water, which greatly reduces the labor and water used.
