Abstract

PURPOSE:To improve germination or growth of seedlings and remarkably improve working environment by placing water in a tank provided with a conveyor, placing nursery boxes containing a bed therein on the conveyor and then infiltrating the water into the bed during movement thereof. CONSTITUTION:The interior of a tank 1 having the opened top is provided with a conveyor 4 and water is then placed in the above-mentioned tank. Each nursery box 3 containing a bed 2 placed therein is subsequently placed and moved on the aforementioned conveyor 4 to dip the lower part of the nursery box 3 in the water during movement thereof and infiltrate the water into the interior of the bed 2 in the nursery box 3. Thereby, good germination and growth of seedlings are carried out without requiring sprinkling of water from the bed 2 thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for applying moisture to the floor of a seedling box for growing rice or vegetable seedlings.

(Prior Art) Conventionally, as shown in, for example, Japanese Utility Model Publication No. 49-27062, the floor in a seedling box was sprinkled with water from above before or after sowing.

(Problem to be solved by the invention) As in the past, when water is poured onto a floor from above, if the floor is made of soil, the impact of the water from above causes the soil particles to collapse and the air content to decrease. This may be unfavorable for germination and seedling growth.

In addition, water poured from above would scatter all over the place, creating a poor working environment even when artificial beds were used.

(Means for Solving the Problems) In order to solve these problems, the present invention includes a conveyor 4 for moving a tank 1 containing water and a seedling box 3 containing a bed 2. This is a seedbed irrigation device characterized in that it is installed in a tank 1 so that the lower part of a moving seedling box 3 is immersed in water and the water seeps into the bed 2 from below.

(Function) The seedling boxes 3 containing the natural soil bed 2 and the artificial bed 2 are sent on the conveyor 4, but on the way to being sent.

The lower part of the box 3 is submerged in the water in the tank 1. Then, the water seeps onto the floor 2, and this floor 2 is irrigated.

(Effects) In this way, since water seeps into the floor 2 from below, it is not hit by water poured from above as in the conventional case.

Depending on the type of city, granulated soil is used for the bed 2, but since there is no impact from water in this invention, the soil particles are less likely to be broken down, which improves germination and growth of seedlings. In good condition.

Furthermore, if water is poured onto the floor 2 from above, the water will spread around the floor 2, but if this is done, the water will be scattered even more widely, making the working environment even worse. In contrast, in the present invention, water is not poured from above, so water is hardly scattered around the device. Therefore, the working environment is greatly improved.

(Example) Next, an example of the present invention will be described based on the drawings.

The plant 7° with the series of conveyors 5.6.4, the sowing device 8, the covering device 9 and the irrigation device 10 are submerged in this order.

The irrigation system 10 includes a tank 1 with an open top.

The conveyor 4 in the irrigation system 10 is filled with water.

It is made of wood and carries a seedling box 3 containing a bed 2 and moves this seedling w13, and claws to push the seedling box 3 are sometimes provided here and there. And this conveyor 4
The upper surface of the tank 1 is lower than the water level in the tank 1 at the middle part.

The tank 1 has a cock 11 for draining water, and the conveyor 4
1±, it is designed to be driven by a motor 12.

The seedling box 3 is usually made of plastic and has a size of about 30aIIX60a++ and a depth of about 3a++, and a large number of small holes 13, 13, . . . are provided in the bottom. Natural soil is placed inside this multi-layered box 3 as a floor 2. This soil.

It may also be artificially processed into granules. Also, the population floor 2
is sometimes included.

Place the seedling box 3 on the left end of the Shijin device 7 facing in the long direction. Then, this seedling box 3 is sent to the right by a conveyor 5 (FIG. 1), and after soil is poured into it, the surface is slightly pressurized to form a bed 2. When this seedling box 3 is conveyed by a conveyor 6 and passes through a seeding device 8, seeds are sown on the floor 2, and soil is placed on top of the seeds by a soil covering device 9.

When the seedling box 3 leaves the soil covering device 9, it is transferred to the conveyor 4.
When moving to the right on this conveyor 4, the lower part descends below the water surface of the tank 1 and is immersed in water. Then, the small hole 13.1 at the bottom
3 Water enters from... and seeps onto floor 2.

The bed 2 of the seedling box 3 is thus irrigated, and the seedling box 3 is taken out from the right end of the conveyor 4.

In addition, in cold regions, a method of spot-seeding rice is sometimes used; in that case, do the following.

That is, as shown in Fig. 4, a paper pattern 15 made of pulp with many trapezoidal pots 14.14 connected from front to back and left and right is placed at the bottom, and the pots 14.14 are placed at the top. Facing it,
It passes through the samurai device 7. Then, each pot 14.14...
...... Soil is put inside and floor 2 is created. This paper pattern 15 is turned upside down and placed in the seedling box 3. The pots 14, 14, . Then, in the same manner as above, the water is irrigated while being fed by the conveyor 4.

In this method, since the floor 2 is covered with the paper pattern 15, it takes a long time for water to flood in from above, so this invention is particularly effective.

Note that it is effective to grow seedlings in the seedling box 3 watered in this manner as follows.

That is, as shown in FIG. 5, seedling boxes 3, 3, . . . are placed side by side in a shallow rectangular water tank 16. This tank 1
6 is an overflow pipe 17 and a drainage pipe 1 on the side wall and lower wall.
8 is provided, and furthermore, a water supply pipe 19 and a fertilizer pipe 20 are provided so that water and fertilizer are supplied.
Water containing fertilizer is filled into the water tank 16 at intervals of time, and the water is drained.

Then, water is intermittently supplied to the bed 2 of the seedling box 3, and the seedlings grow well.

For water supply and drainage, it is preferable to provide an electromagnetic valve 21 to automatically supply and drain water, and it is preferable to place a mat 23 with a heater 22 on the bottom of the water tank 16 (FIG. 6).
