Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a method for raising and transplanting paper tube seedlings by filling two groups of bottomless paper tubes with culture soil, sowing seeds, raising seedlings, and transplanting them. .

Conventional technology The conventional technology for raising and transplanting seedlings using bottomless paper tubes is as shown in Japanese Patent Publication No. 38-25714, in which a group of paper tubes is laid out on a base plate, filled with soil, seeded, and then transplanted. There is a method of removing the boards, placing them in a nursery, raising the seedlings, and transplanting them after the seedlings have been raised.

Furthermore, as shown in JP-A-61-111629, there is a method in which a group of paper cylinders is laid out on a protruding plate, packed with soil, turned over, coated, and sown one by one to raise seedlings and to be used for transplantation. be.

Furthermore, a method is known in which a group of paper tube seedlings placed on a seedling bed is transferred using a fob-like tool during the seedling-raising period, which is called changing the bed.

Problems to be Solved by the Invention Seedlings are raised using bottomless paper tubes, and the roots of the seedlings are wrapped in the soil of the paper tube and transplanted to the main field, but when taking the paper tube seedling group from the nursery, The root tip of the seedling that protrudes from the bottom of the paper tube is cut or damaged, and even if it is transplanted to the main field as is, it will take several days for the roots to penetrate into the soil of the main field. There is a problem in that the so-called delayed rooting phenomenon causes a delay in growth and leads to a decrease in yield.

In the case of sugar beet seedlings, the amount of roots that have developed beyond the bottom of the paper tube is small;
The above problem can be solved by changing the bed and waiting for the root growth to recover before transplanting, but the paper cylinder used for raising sugar beet seedlings is 1.9X13an to 1.9X15.
c! A collection of 1,400 l-sized paper tubes becomes a book, which weighs more than 70 kg when filled with soil, and moving them is hard work.

In addition, the length of the paper tube for onion seedlings is 4.3an, and when I tried to change the bed as mentioned above, the roots had fully developed into the bed soil, so when I tried to move the paper tube group, the seedlings There was a problem with the crabs coming out of the 6Q, so the roots had to be cut at the bottom of the paper tube, which was also hard work.

In other words, it is an object of the present invention to provide a method for easily changing the bed or cutting roots in order to prevent delays in rooting during paper tube seedling raising and transplanting.

Means for Solving the Problems The method of raising and transplanting paper tube seedlings according to the first invention relates to seedlings such as sugar beet seedlings with long paper tubes and whose roots do not extend much into the seedbed as shown in Fig. 1. As shown in T, place a bottomless paper cylinder 1 on top of the earth filling machine, etc.
7 groups are laid out and placed, culture medium ±18 is packed, and base plate 2 is placed on top of 1 paper tube 17. After that, it is turned over and the base frame 1 of base plate 2 with paper tubes 17 group a is placed on the seedbed. At the end of the seedling-raising period, the group of paper tube seedlings is moved away from the nursery bed along with the white board 2 by holding the side frame handle by hand, and the roots that have grown into the nursery bed are cut and the roots are removed. Waiting for the increasing strength to recover, and after seedling raising is completed, paper tube seedlings are placed on the base plate 2 and used for transplantation.

The method for sterilizing and transplanting paper tube seedlings according to the second invention is mainly concerned with seedlings such as onion seedlings whose paper tubes are short and whose roots have spread considerably into the seedbed. bottomless paper cylinder 17
The group is laid out and placed, culture medium ±18 is packed, the base plate 2 is brought into contact with the paper tube 17, and then the base plate 2 is turned over and the base frame 1 of the base plate 2 on which the paper tube 17 group is placed is placed in the seedbed. Seedlings are grown by placing them in close rows, and at the end of the seedling growing period, a root cutter or a root cutter is used as a root cutter between the base plate 2 and the bottom of the paper tube 17 to cut the roots, and the roots grow. After waiting for the power to recover, and after seedling raising is completed, paper cylinder seedlings are placed on the base plate 2 and used for transplantation.

Function The method of the first invention is to raise seedlings in paper tube seedlings from the beginning on the base plate 2, and to transfer the roots that have passed through the holes 3 drilled in the base plate 2 and developed into the seedbed to the side frame i. Separate the paper tube seedling group along with the base plate 2 from the seedbed by holding it by hand, etc., and cut it all at once.

In the method of the second invention, a group of seedlings in paper tubes is raised from the beginning on a bed plate 2, and the roots that have passed through holes 3 drilled in the bed plate 2 and developed into the seedbed are placed between the bed plate 2 and the paper tube. The roots are cut all at once by passing the cutting thread 28 of the root cutter or the cutting blade 25 of the root cutter 24 as a root cutter between the bottoms of the roots 17 and 17.

In addition, the paper tube seedling group is kept on the base plate 2 during the seedling raising period and at the time of transplanting.
It is placed on.

EXAMPLES Below, the apparatus and working method used in the present invention will be explained according to the examples shown in FIGS. 1 to 3.

FIG. 1 is a perspective view of a seedling box and a group of paper tube seedlings used in the present invention.

The seedling box has a base plate 2, which is a rectangular flat plate, with holes 3 corresponding to or more than the individual paper tubes 17 of the paper tube group, and both long sides of the base plate 2 are bent downward for reinforcement. The long sides of the 0-base board 2 on which the ribs 4 are disposed and one frame is made are slightly longer than the long sides of the paper tubes 17 groups, and the short sides are approximately the same length.

Side plates 6 are installed vertically at both ends of the short sides of the underframe 1, and the height of the side plates 6 is approximately the same as the height of the paper cylinder 17', but may be slightly higher than the height of the paper cylinder 17 if stacking is necessary.
