Example Embodiment

[0020] Example 1

[0021] (1) Nursery

[0022] Seed selection: Use a 10% sodium chloride solution to float the seeds, remove the floating seeds, remove the settled plump rice seeds, wash them with clean water, and set aside;

[0023] Germination: Expose the full rice seeds obtained by selection to the sun for 72 hours; soak the seeds with 1% lime water at 15°C for 48 hours; then remove the seeds and wash them with water; wrap the seeds with a damp cloth and place them at 35°C 12h in the incubator;

[0024] Sowing: Choose a seedling field with high terrain, flat, moderate water seepage, and convenient irrigation and drainage as the land for raising rice seedlings. The seedling field is loosened to achieve finely broken soil, flat field surface, ditching compartments, compartment width 130cm, ditch width 25cm, ditch 12cm in depth; 150kg of pig manure and 20kg of NPK compound fertilizer are applied per mu of seedling field. The weight ratio of N, P and K in the NPK compound fertilizer i...

Abstract

The invention discloses a rice seedling culture method. The seedling culture method includes seed selecting, germination accelerating, sowing and disease and insect damage preventing and treating. The rice seeding culture method is optimized to improve seedling growth vigor and then remarkably increase the rice yield.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for raising seedlings of rice. Background technique [0002] By popularizing academician Yuan Longping's hybrid rice, it not only solves the food problem of China, which accounts for a quarter of the world's population, but also solves the "bottleneck" that is difficult to increase the output of many rice-growing countries in the world, thus greatly helping to alleviate the world food crisis. [0003] This is a gratifying progress, but with the growth of our country's population, the reduction of cultivated land, the small scale of production, the shortage of water resources, the threat of drought, and the promotion of returning farmland to forests have objectively exacerbated the contradictions in food demand. , coupled with my country's relatively backward technology and weak service system, it also shows that there are still various hidden dangers and risks in my country'...
