Description

Rice nursery-box with no hole at the bottom}

Seedling boxes are essential in the rice paddy for mechanical migration. Currently used seedling boxes have holes at the bottom, such as the nursery box of Fig. 1-1 and the seedling box of Fig. 1-2. The number of holes is 2800-3200 4mm in diameter for seedlings and 20-30 in diameter 3mm for young seedlings. The use of this hole is for the movement of water and the growth of roots in seedlings, and for the movement of water in seedlings. The seedlings are placed on the rice paddy for 30 days so that the roots absorb the nutrients from the bed soil. In the nursery, because the nursery is placed in the field or the room, the number and size of the holes are reduced only for water drainage. It is hard to remove this box because it is stretched. To prevent rooting, a thin vinyl film is placed on the floor, but the task of laying and collecting is very cumbersome. Seedling boxes with few holes and little rooting at the base have emerged, which have the advantage of not laying vinyl on the floor in dry land or in a plastic house, but a major drawback of this is the warping of boxes during use. This is not the case for seedlings, because many of the holes in the bottom absorb elongation and contraction reactions due to changes in the temperature of plastics. It will take time for it to be replaced. To use seedling boxes for indoor nursery, vinyl must be placed on the floor. In the use of the holes, the seedling boxes are mainly used for water to enter the box, and the seedling boxes are often used for draining irrigation water. When using a kind of seedling box or growing in a field or a plastic house rather than a rice paddy, watering is essential. If water is easily drained, the number of watering should be increased. This is uneconomical in terms of the use of water and labor, so the more water stayed for a long time, the more efficient it is.

1. Seedling box without bottoms

In the conventional seedling box, the seedling box has its roots so low that it is difficult to remove the box from the mother bed, and to put a vinyl on the floor to prevent it. Is the development of a box that eliminates the hole in the bottom of the box, which was previously considered to be essential, and has a hole at the top of the side, or without a leading edge. It is to save water and labor by keeping water in the seedlings for a long time with one watering so as not to fall out. One of the disadvantages of nursery boxes with irregularities on the bottom is one of the drawbacks of the nursery, because of its structural distortion. This can be prevented by forming irregularities on one or both sides of the bottom to absorb internal expansion and contraction due to temperature changes of the plastic. No reprocessing method of existing low oil box. Currently, every farm has as many seedling boxes as needed. In Korea's total arguments, 244 million low seedling nursery boxes are currently in use. Of these, only 5% are replaced by new ones every year, so it takes a long time to replace all the new models, which increases the amount of time it takes to be uncomfortable. If they are replaced at one time, the existing boxes will be discarded, which would result in a waste of resources, so it is also necessary to develop a method for emptying existing low floor nursery boxes at low cost.

In the present invention, the size of the seedling box is the same as the existing seedling box (Fig. 1), and is based on the absence of a hole in the bottom (Fig. 2, Fig. 3, Fig. 4, Fig. 5). As an example, the whole box is divided into no holes (Fig. 2) and only holes on the side (Fig. 3), and each of them is divided into flat surfaces and irregularities. Same as

Example 1: The whole box is a seedling box with no holes and the bottom is flat (FIGS. 2-2 and 5-1). Example 2: There is no hole in the whole box and the outside of the bottom is as shown in FIG. Unevenness (3) is on the side. The shape of the unevenness is cylindrical (Fig. 4-1, Fig. 5-2) or cup shape (Fig. 4-2, Fig. 5-2), and the grooves forming the unevenness are 4-8mm inlet diameter and 1-3mm in depth. As a result, there are 3000-3500 pieces in the whole box. Example 3: There is no hole in the whole box, and there are irregularities on the inner side of the bottom as shown in Fig. 2-4. The shape of the unevenness is cylindrical (Fig. 4-1, Fig. 5-2) or cup shape (Fig. 4-2, Fig. 5-2), and the grooves forming the unevenness are 4-8mm inlet diameter and 1-3mm in depth. As a result, there are 3000-3500 pieces in the whole box. Example 4: There is no hole in the whole box, and irregularities as shown in Fig. 2-5 are on both sides of the base. The shape of the unevenness is a columnar shape (Figs. 4-5 and 5-2), a cup shape (Figs. 4-6 and 5-2) or a rectangle (Figs. 4-7 and 5-3), and the grooves forming the unevenness Has a mouth opening diameter of 4-8 mm and a depth of 1-3 mm, and there are 3000-3500 pieces in the whole box. Example 5: A seedling box having a completely flat bottom, as shown in Fig. 3-2, with holes only. There are several round or rectangular holes of 2-3 mm in diameter on each side of the side edge. Example 6 There is a hole only on the side of the box, and the unevenness 3 is present on the outer side of the bottom side as shown in Fig. 3-3. The shape of the unevenness is the same as that of the second embodiment. Example 7: There is a hole only on the side of the box, and the unevenness 3 is present on the inner side of the bottom as shown in Figs. The shape of the unevenness is the same as that of the third embodiment. Example 8: There is a hole only on the side of the box, and the unevenness 3 is present on both sides of the bottom as shown in Figs. The shape of the unevenness is the same as in Example 4. Example 9:

The empty box as shown in Fig. 2-3 or 2-4 can be made by filling the hole of the already manufactured low bottom oil box or by adding a thin plastic film having a thickness of 0.1-1.0 mm to the bottom.

In wet seedlings, there is no rooting through the base of the box, so the box can be easily removed from the bed plate. It reduces the consumption of labor, and the mother absorbs enough moisture, which improves growth. Rice grows well in the natural water, so there is no damage from overheating.
