Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a cultivation device for making seedlings.

[0002]

[Prior art and its problems]

 The conventional method of making nursery is to crush the soil in the fields and finely divide it, and to equalize it while supplying water to make a nursery.

Next, a nursery box disclosed in Japanese Patent Publication No. 47-49246 or a nursery box disclosed in Design Registration No. 384504 is pushed down and cultivated in the nursery.

[0004] At that time, the bottom surface of the nursery box must be in close contact with the surface of the nursery bed. In other words, if the floor of the nursery box does not adhere to the nursery, the soil of the nursery box will dry and the seedlings will not grow.

[0005] In addition, since the seedling box is made of a hard synthetic resin, the surface of the seedlings must be soft. However, if the seedling box is very soft, the soil and seeds packed in the seedling box may fall.

[0006] Furthermore, if the surface of the nursery becomes hard, it is difficult to make the nursery box and the nursery adhere to each other. It takes effort.

When the nursery box is separated from the nursery, the topsoil of the nursery must be dried and hardened, and the soil at the bottom of the nursery box must be cut off at the same time as the roots of the seedlings.

[0008] A known seedling harvester is used for the above cutting.

This seedling picking device is composed of a gripping rod, a forked rod projecting from the tip of the gripping rod, and a wire stretched between the tips of the forked rod. Cut the root and soil while positioning the tip of the fork and pulling the grip so that the wire passes between the seedbed and the bottom of the nursery box.

[0010] However, since the roots of the seedlings, waste chips, garbage and the like are entangled in the wires, the roots cannot be cut off smoothly, and a great deal of labor is required. As a result, the efficiency is significantly reduced. That is, nursery boxes cannot be taken continuously.

Particularly, since the nursery box is pushed into the soil, the floor soil enters the space behind the nursery box.

[0012] In this state, even if root cutting is performed using the wire of the seedling harvester described above, it is not possible to scrape the soil that has been digged in by cutting the bottom of the seedling box with the wire.

For this reason, the weight of the nursery box to be taken out is increased, and handling such as carrying out is difficult. At the same time, heavy labor is liable to cause back pain and the like.

Of course, in order to eliminate the above-mentioned problems, it is necessary to scrape the soil using a kitchen knife or the like on site.

[0015] If the above operation is insufficient, if the planting is performed using a rice transplanter, it is not possible to grasp the seedlings smoothly with respect to the seedling raising box due to the entanglement of the soil and roots present on the lower surface of the seedling raising box. It also causes the lack of stock.

In addition, if the soil in the nursery is soft, the seedlings are rooted in the soil, and the roots of the seedlings are not cut off. Was

An object of the present invention is to provide an apparatus for cultivating rice seedlings, which makes it possible to take out a nursery box from a nursery bed extremely smoothly.

[0018]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the present invention consists of a net laid on a nursery and a nursery box placed on the net, and a root cutting thread for cutting the root as it is drawn on the net. Adopt the arranged configuration.

[0019]

[Embodiment of the invention]

 An embodiment of the present invention will be described with reference to the accompanying drawings.

The nursery box A used in the embodiment of the present invention, as shown in FIGS. 1 and 2, is divided into a rectangular frame 1 whose upper and lower surfaces are open and a section inside the frame 1. Soil 3 is put into a partition space composed of vertical and horizontal partition plates 2 and divided by the frame 1 and the partition plate 2 and by the partition plate 2, then sowing a is sowed, and then the covering soil 4 is formed. I do.

The soil 3 and the covering soil 4 are packed by pressing the seedling box A so that the seedling box A does not fall off when the seedling box A is cut and handled.

Next, the cultivation means will be described.

[0023] The fertilizer is sprayed on Naeshiro (Hirata dry field), and the soil is plowed as shallowly and finely as possible.

Next, after the ridge is formed, water is applied to the inside of the ridge to soften the soil of the nursery 11. Thereafter, as shown in FIGS. 3 and 4, a net 12 is laid all over the nursery bed 11 inside the ridge.

At this time, the upper surface of the nursery 11 is leveled horizontally and parallel. Then, muddy water (floating water of fine mud) floats on the surface of the net 12.

Then, the seedling raising box A is placed on the net 12 and the seedling raising box A is lightly pressed against the net 12 so that the seedling raising boxes A are sequentially arranged.

Prior to placing the seedling box A, a root cutting thread 13 for pulling the seedling on the net 12 to cut the root is arranged.

The net 12 is desirably a rigid synthetic resin molded product. Note that the root cutting thread 13 may be any material that can withstand a strong pulling force.

As shown in FIG. 3, two sets of root cutting threads 13 are arranged at the center of the seedling raising box A in each row of the seedling raising boxes A arranged in series as shown in FIG. I do. At this time, both ends of the root cutting thread 13 are positioned on the ridge.

The arrangement of the root cutting thread 13 is not limited to the above. In short, it is only necessary to grab the end and pull in the direction of the opposite end to cut off the root. In addition, the root is cut while pulling the root cutting thread 13 in an X shape.

When configured as described above, when the seedling raising box A is taken out, both free ends of the root cutting thread 13 are drawn.

Then, the root between the net 12 and the seedling raising box A is cut, and the removal of the seedling raising box A becomes easy.

As a matter of course, with the root cutting by the root cutting thread 13, the pulled-out root by lifting the seedling raising box A does not exist on the lower surface of the seedling raising box A.

[0034]

[Effects of the Invention] Since the cultivation apparatus for rice seedlings according to the invention is configured as described above, the root between the nursery box and the net can be cut by the root cutting thread.

Therefore, there is an advantage that the seedling raising box can be taken out smoothly, the seedlings do not remain in the seedbed, a great deal of labor is not required for taking out the seedlings, and no back pain is caused.

[0036] In addition, with the complete root cutting between the net and the seedling raising box by the root cutting thread, the seedling can be smoothly taken out by the planting mechanism by the rice transplanter, and the occurrence of lack of stock can be eliminated. it can.

Of course, since the seedling box is placed on the net, the bottom of the seedling box is not clogged with soil. Therefore, workability such as loading on the rice transplanter is also improved.
