Abstract

One way to reduce the amount of topsoil in the seedlings of the capital is to suggest how to use sowing paper, and the sowing paper consists of flat paper consisting of lower grade paper or paper with a special structure.

Description

Application of seeding paper to rice nursery}

Currently, when the base plate is installed in paddy fields or indoors, it is placed in seedling boxes of a certain standard (inside area: 273x573x30). The bed soil that enters here is to use Sanyato finely or specially processed.

If you put about 2.5kg of soil in a bowl and water it, it will weigh 3-4kg. Topsoil manufacturers already know the need to reduce the weight of the topsoil and add organic matter to the topsoil.However, unlike horticulture, the topsoil is very heavy, consisting of soil and ore. We are well aware that good soils must be used to produce faithful wool. In the future, as rural labor force is getting older, it would be better to have a way to reduce the amount of topsoil while raising faithful seed.

An object of the present invention will have to reduce the amount of use of soil in a range that does not interfere with the growing of the soil if it is forced to continue to use heavy soil. This is possible by using seeding paper. Sowing conditions should be able to replace the work of the soil in relation to plant roots. In order to reduce the amount of topsoil and make the roots well mated, there is a condition that the seedlings must have affinity with the roots, and the roots must grow normally in this genus. Use nutrient solution. For mat formation of roots, all roots need to be localized in seedling boxes, and boxes must have no holes at the bottom.

1 is three cross-sections of the form of the baseboard, Figure 1-1 is uneven seeding map 1-2 is porous sponge baseboard map 1-3 is a base paper

2 is an example of a seeding method using a base paper, Figure 2-1 is a seeding method that puts soil on the base paper Figure 2-2 is a seeding method that does not put soil on the base paper Figure 3 is a seedling box available when using the mother paper As a form, Fig. 3-1 shows a conventional seedling box. Fig. 3-2 shows a seedling box that is twice as wide as a conventional seedling box. Fig. 3-3 shows a seedling box that is twice as long as a conventional seedling box.

Composition and form of sowing paper : The thickness of the sowing paper ranges from 0.5 to 10 mm depending on the material used and the seedling method, and the shape is divided into three types according to the type of material. Either way, it consists of the direction of enhancing the bovine, conservative and near-term development.

In detail, the composition and shape of the paper is 0.5-10 mm thick, and the surface has irregularities, or the surface is uneven, so that the rough paper is laminated in several layers (Fig. 1-1), or there is a lot of voids in the interior. Loose to form a void inside, such as a sponge (Fig. 1-2), or a paper-like form (Fig. 1-3) using a flat paper from the paper mill as it is. Sowing method: Seeding method on seedlings is as shown in Fig. 2-1, place seeding paper (7) on the bottom (8) of seedling box, place soil (6) on it, then put seeds (5) on the top and cover the top (4). ) And the seeding method 7 is placed on the bottom of the box, and the seed 5 is placed on the bottom of the box as shown in FIG. In any case, the seedling site is the lowest on the bed, and the top is the top soil covering the seed. Seedling box: When using the seedling paper, the seedling box is not only not only the outer diameter 300 x 600mm currently used as shown in Fig. 3 (Fig. 3-1), but also it is modified to double the area (Fig. 3-2). ) Or doubled in length (Fig. 3-3), or anything larger than using a concrete floor or a plate of a facility, not a container. 3, it is more advantageous to use a box without a hole at the bottom when using a seeding paper and supplying nutrients with nutrient solution. Some examples of the seeding method carried out for each type of seeding paper are as follows. Example 1 Laying a seedling paper (Fig. 1-1) on the bottom of a seedling box, spreading the top soil 1-5 mm thick on top of it, sprinkling the best rice seed on it, and covering the top soil 0.5-1 mm to form a mother bed (Fig. 2-). One). Lay several sheets of sheets to cover the vinyl and stretch the seedlings 2-3cm. When irrigation is necessary, the nutrient solution is used together with the nutrient supply. Test Results: As a result of examining the growth of seedlings by type of sowing, the pulp paper was slightly lower as shown in Table 1, and the cardboard was the same as the control. Control refers to the practice of using large amounts of soil as a base. Effect of Type of Sowing on Seedling Growth Type of planting site (head) Extra long (15 days after sowing) Whether to use clay Pulp Paper (0.05mm) 19 cm Inorganic soil 1 layer of cardboard (0.25mm) 20 cm Inorganic soil 2 layers of cardboard (0.5mm) 20 cm Inorganic soil Contrast (top 10mm) 20 cm Land use Example 2: A sponge-type seeding paper (Fig. 1-2) composed of paper pulp was laid on the bottom of the seedling box, and the top soil was spread to a thickness of 1-5 mm on top of the seedling box, sprinkled with the best seed on it, and then the top plate was covered with 0.5-1 mm. (Fig. 2-2) When several sheets of laminae are laminated and covered with vinyl, the seedlings are stretched 2-3 cm, and they are spread out on the bedrock or on the ground and grown under light. When irrigation is necessary, nutrient solution is used and nutrient supply is carried out. Test Results: As a result of examining the growth of seedlings by type of sowing, the pulp paper was slightly lower as shown in Table 2, and the cardboard and the control were the same. Effect of Type of Sowing on Seedling Growth Type of planting area (thickness) Extra long (15 days after sowing) Whether to use clay Pulp Paper (0.05mm) 19 cm 1mm earth Cardboard (0.25mm) 20 cm 1mm earth Pulp Plate (10mm) 20 cm 1mm earth Contrast (Top 10mm) 20 cm 10mm earth

Reduced soil use: The advantage of using sowing land is to reduce the amount of soil that is done by using less soil (6) than conventional practice. The practice is to use 10-20 mm of topsoil as soil, but when using seeding paper, soil is not used at all or only slightly. Improved work efficiency: The base plate is light and convenient to handle and improves work efficiency. In full-time nursery plants, the load on the bed is less, allowing the space of the facility to be used more three-dimensionally.

Reduction of logistical costs of subsoil: As the amount of subsoil use is reduced, the transportation cost of materials and products is reduced, resulting in less production cost.
