Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 This invention relates to a cultivation apparatus 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 and a nursery box disclosed in Japanese Patent No. 384844 are sunk into the nursery and cultivated.

[0004] At that time, the bottom surface of the nursery box must be in close contact with the surface of the nursery bed. That is, if the floor of the nursery box of the nursery does not adhere, 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 seedling margin must be soft.

[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.

Further, when the nursery box is separated from the nursery bed, the top soil of the nursery bed 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. While positioning the tip of the fork, cut the root and soil while 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, broken 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.

[0011] That is, it is not possible to take a nursery box continuously. In particular, because the nursery box is pushed into the soil, floor soil has entered 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 penetrated by scraping the bottom of the seedling box with the wire. For this reason, the weight of the nursery box to be taken out increases, handling becomes difficult, such as carrying out, and the back labor is likely to occur due to heavy labor.

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

[0014] 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.

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

Therefore, there is Utility Model Registration No. 3054822 as an apparatus for cultivating rice seedlings that eliminates the various disadvantages described above. According to this known example, the root is cut while pulling the root cutting thread between the net and the seedling raising box.

[0017] However, there is a disadvantage that the drawn thread is caught at a corner of a nursery box or the like, and if the thread is pulled with a strong force, the thread is cut.

In addition to the above-mentioned catch, the root cutting thread comes into contact with the soil protruding from the bottom of the seedling raising box, so that the root cutting thread is worn and cut with the contact with the soil.

In particular, the protruding soil has an inverted V-shape from the bottom of the seedling raising box, and since the protruding length varies depending on each part, the cutting of the root cutting thread becomes remarkable.

Therefore, an object of the present invention is to provide an apparatus for cultivating a seedling in which root cutting thread is not caught or cut.

[0021]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, this invention consists of two upper and lower nets laid on a nursery and a nursery box placed on the upper net, and the upper net and the lower net are connected to each other. Adopts a configuration in which a root cutting thread that cuts the root due to pulling in between is arranged.

[0022]

[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 placed in a partition space composed of vertical and horizontal partition plates 2 and divided by the frame 1 and the partition plates 2 or by the partition plates 2 and then sowing a and sowing. Cover the soil 4.

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 during the cutting operation.

Next, the cultivation means will be described. Sprinkle fertilizer on Naeshiro (Hirata Inui) and cultivate as shallow and fine as possible.

Next, after the ridges are formed, water is applied to the inside of the ridges to soften the soil of the nursery 11 and then, as shown in FIG. 3 and FIG. Lay the nets 12 and 13.

At this time, the upper surface of the nursery 11 is leveled horizontally and parallel. Then, muddy water (fine mud floating water) floats on the surface of the upper net 12. Then, the seedling box A is placed on the upper net 12, and the seedling box A is lightly pressed against the net 12, so that the seedling boxes A are sequentially arranged.

Before the seedling box A is placed, the root cutting thread 14 that draws and cuts the root between the upper net 12 and the lower net 13 is arranged.

The upper and lower nets 12 and 13 are preferably made of a hard synthetic resin molded product. Note that the root cutting thread 14 only needs to withstand a strong pulling force.

As shown in FIG. 3, the root cutting thread 14 is arranged such that a pair of root cutting threads 14 are arranged at the center of the seedling raising box A in each row of the seedling raising boxes A arranged in series. I do. At this time, both ends of the root cutting thread 14 are positioned on the ridge.

The arrangement of the root cutting thread 14 is not limited to the above, and may be, for example, an arrangement as shown in FIG.

In short, it suffices if the end can be cut by grasping the end and pulling in the direction of the opposite end. Further, the root can be cut while pulling the root cutting thread 14 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 14 are drawn. Then, the root between the upper net 12 and the lower net 13 is cut, and the seedling raising box A can be easily taken out.

Needless to say, with the root cutting by the root cutting thread 14, no roots are pulled out by raising the seedling raising box A on the lower surface of the seedling raising box A.

The above-mentioned cultivation is not limited to paddy rice seedlings, but is also applied to root cutting when cultivating vegetables having roots extending in the vertical direction, for example, onion seedlings.

[0036]

[Effect of the invention]

 Since the seedling cultivation apparatus according to the present invention is configured as described above, the root cutting thread between the upper and lower nets is drawn to cut the root between the upper and lower nets.

[0037] Therefore, there is no inconvenience that the attracted root cutting thread is caught by the nursery box and cut off, and there is no inconvenience that it is worn off by contact with soil.

[0038] Therefore, there are advantages that the nursery box can be taken out smoothly, no seedlings remain in the nursery bed, no great effort is required for taking out, and no back pain is caused.

In addition, with the complete root cutting between the net and the seedling raising box by the root cutting thread, it is possible to grasp and remove the seedling smoothly by the planting mechanism by the rice transplanter, and to eliminate the occurrence of lack of stock. 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.

[0041] In addition, smooth root cutting can be performed with the cultivation of vegetable seedlings whose roots extend in the vertical direction other than the cultivation of rice seedlings.
