Abstract

The present invention is to reduce the amount of top soil to less than 1/6 to significantly improve the weight of the bed plate in the current box box nursery seedlings and high soil costs, and the seedling box to be used in this method is a tube Drainage perforated only on the side walls of the box.

Description

Raising methods of rice-seedling with saved nursery soil and its box}

When rice is machined, it is grown in seedling boxes (inside area: 273x573x300mm). Mopanto

Loess is usually used in mountainous loess, but is usually used for mass nurseries or nurseries.

Some farmers buy and use manufactured topsoil.

The depth of the bed is made of 30mm for the seedlings and 20mm for the seedlings.

After the end cover, the depth is filled to 25mm and 20mm respectively. The amount of soil used

It is about 3L per weight, and after watering, the weight is about 5-6kg. Hundreds of farms per farm

Because of their bedrock, it's hard to deal with them. The cost of using

When it is used, it makes 6-8 sheets with 20kg Hanpo, so it is calculated as about 500 won per plate.

Two important roles of bedrock are to nourish and moisturize the hair, and

It is to keep the shape of the bed plate when moving. Ocher in the soil

It is used a lot because of its excellent function. Lots of ocher or other types of clay are also found in manufacturing soils.

As it is used, watershed soils are usually heavier than horticultural soils.

If you have to continue to use heavy soil in the seedlings,

If the weight of the bed can be reduced within the range of

It will help to reduce the labor burden and reduce the production cost. Recently in some

In the group nursery, which is practiced in Western countries, the need to lighten the weight of the bed plate is more realizing.

All.

The problems of the current nursery are summarized as follows.

o It is difficult to collect mopland soil in nature.

o The manufactured soil is expensive (2,500-3,000 won / bag) and has a limited supply of raw materials.

o The seeded bed has a heavy weight of 5-6 kg / plate).

o The working efficiency is low because a large number of spare caps cannot be mounted on the machine during transplanting operations.

In order to achieve the object of the present invention, the following detailed problems have been solved.

Use of small amounts of topsoil leads to simulated normal growth

o Development of methods to promote mat formation of seedling roots

o Development of continuous supply of nutrients needed for seedling growth

o Adaptability to existing rice transplanters

1 is a five-type sowing process made in the box nursery of the present invention

Fig. 2 shows three models of mother board used to help save the soil.

Figure 3 is a kind and structure of seedling box used in the present invention

Use small amounts of topsoil:

There are five ways to plant seedlings. As shown in Fig. 1-1, the mother board (4) is placed on the bottom (3) of the bed plate, the soil (5) is placed on it, the seed (6) is placed on the top, and the top is covered with the cover (7). Based on the following method, the seeding method is composed of each combination except for the mother board, clay and cover (Fig. 1-2, Fig. 1-3, Fig. 1-4 and Fig. 1-5).

It is the first feature of the present invention that in any seeding method the use of very little soil is less than 600 ml, which is about 1/6 of the conventional one. The seeding procedure is the same as that of the conventional method except that the seeding paper is used, and the amount of soil used is significantly different from the one not used all the way up to 500 ml. When it is sprayed on the seedling box, the thickness is less than 2mm, which is very small compared to the existing thickness of 10-15mm. Cover is less than the amount of clay, not more than 100ml.

Motherboard Use:

The mother board is 0.5-5mm thick paper covering the bottom of the seedling box as shown in Fig. 1, and is made in various shapes as shown in Fig. 2. The mother board supplements the strength of the mother board and increases the bobbin power and water retention. Although the use of sowing paper is not essential in the present invention, the poor development of the roots is very advantageous because it strengthens the mat of the roots.

In order to explain the mother board in more detail, FIG. 2 shows a mother board having three types of structures. Corrugated cardboard (8) is composed of three parts, both sides and the center, like a normal cardboard, the upper surface uses a thin lipid so that the root can easily penetrate. The total thickness of the corrugated sheet is determined by the thickness of the central corrugation layer and ranges from 2-5 mm. The porous base paper 9 has a loose structure, such as a paper towel, or a rough surface due to the roughness of the surface. The base paper base paper 10 is a flat paper from a paper mill and varies in thickness. .

The mother board may contain three elements of the fertilizer and other trace elements during the manufacturing process, or the seeding paper may be wetted with a solution of these components at the site of use.

Nutrient supply formula:

In order to make normal hair with such a small amount of bed soil, in the present invention, the second feature is to separately supply nutrients after sowing. The feeding method is spraying or irrigation of the nutrient solution on the mother plate. The problem of nutrient feeding to seedlings is that instead of using less soil, the nutrient solution is supplied to the bed after germination so that the plant can continue to absorb nutrients. The composition of the nutrient solution is suitable for the growth of rice. This growing mother has no difference between the previous thickening and thickening of the motherfan.

Use the side ball nursery box:

All of the existing seedling boxes have holes in the bottom of the box. This is necessary since rooting and water passage are necessary depending on the seedling method. However, in the present invention, since a nutrient solution is used, a seedling box (Fig. 1-1 and 3-1) having a hole 1 on the side instead of the bottom is used. Is the third feature. Its position is about 15mm from the bottom of the box and about 18 with a diameter of 3mm. In indoor nursery, this hole serves only as drainage, but when it is transferred to the paddy field and grows in fresh water, it also serves as watering and drainage.

The seedling box described above was based on the currently used outer diameter of 300 x 600 mm (Fig. 3-1), but as the weight of the bed plate becomes lighter, the width of the seedling box is 1.5 times, 2 times the present size (Fig. 3-2) or Increasing the ratio of guitars can improve work efficiency. In addition, the same effect can be achieved by using the ground or the plate of the facility instead of the container.

This invention can be used by all the rice mills that machine the water, the following benefits can be obtained.

o Reduces the production cost of rice by saving the mofan.

o Lighter bed makes work easier and reduces labor demand.

o Logistics costs of subsoil transported between regions are reduced.
