Embodiment Construction

[0043] Set the seedbed on the land according to the conventional method, and level the soil in the seedbed to make a good border.

[0044] 1. Lay plastic film on the seedbed

[0045] Spread a layer of plastic film on the seedbed.

[0046] 2. Spread seedling substrate

[0047] The seedling-raising substrate adopts expanded perlite particles with a particle size of 0.2-2 mm and a thickness of 0.5-1.5 cm.

[0048] The expanded perlite matrix can be made by expanding the perlite ore of 40-110 mesh, or the perlite ore can be puffed and then crushed to make expanded perlite of 0.2-2mm as the matrix.

[0049] 3. Drenching liquid fertilizer

[0050] Dilute the rice seedling-raising special fertilizer according to the mass ratio of 1:100, pour it evenly on the seedbed, use 500 grams of seedling-raising fertilizer per 50 square meters of seedbed, and then pour the seedbed evenly with clean water until the water content is saturated until it does not flow out.

[0051] The formula of...

Abstract

The invention provides a rice seedling culture method. The rice seedling culture is realized by the steps: 1. paying plastic films through a seedling bed; 2. paving a seedling culture substrate; 3. spraying fertilizer liquid; 4. pre-treatmenting before seeding rice; 5. seeding; 6. managing the seedling bed; and 8. controlling inset pests at the seedling stage. By adopting the rice seedling culture method to culture rice seedlings, the invention has the advantages of quick seedling emergence, robust seedling bodies, insect pest resistance, developed root system, easy formation of seedling pieces, favorability for mechanical transplantation and quick seedling regrowing and is suitable to be used for rice seedling culture.

Description

technical field [0001] The invention proposes a plant cultivation method in the agricultural field, specifically a rice seedling cultivation method. Background technique [0002] Before the present invention proposes, paddy rice adopts soil sowing to raise seedlings. Because seedlings have strict requirements on soil fertility, air permeability, and pest conditions, it is difficult to grow strong seedlings without pests and diseases by adding chemical fertilizers to ordinary soil, and the root system is not fully developed. After planting, the seedlings are slow and the growth rate is slow. directly affect the yield and quality of rice. [0003] Another biggest disadvantage of ordinary soil seedlings is that when the seedlings are raised after the seedlings are established, the seedlings are not easy to be continuous, and there are scattered seedlings. Contents of the invention [0004] In order to overcome the existing problems of raising seedlings in common soil, the p...
