Problems solved by technology

[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 science and technology and weak service system, it also shows that there are still various hidden dangers and risks in my country's current food problem that cannot be underestimated
[0004] However, the high-tech transgenes we rely on now can change the quality and traits of rice, but they cannot increase the yield of crops. At the same time, because the price of transgenic seeds is much higher than that of ordinary improved seeds, the cost of agricultural planting has increased. It is a feasible and effective method to find out the most suitable planting method for crop growth through planting experience to increase food production.

Embodiment 1

[0026] (1) Seed soaking: select hybrid rice varieties with great potential for yield increase, remove the deflated, damaged and heterogeneous seeds from the rice seeds, and expose them to sunlight for 2 days; then soak the seeds with 3% lime water at 15°C until they become clear ;

[0027] (2) Seedling raising: Choose a seedling field with high terrain, flat, moderate water permeability, and convenient drainage and irrigation as the land for raising rice seedlings, and dig the seedling field to make the soil finely broken and the field flat; apply 150kg of pig manure and nitrogen, phosphorus and potassium per mu of seedling field 20kg of compound fertilizer, the weight ratio of nitrogen, phosphorus and potassium in the compound fertilizer of nitrogen, phosphorus and potassium is 1:0.5:0.8; then 1kg of rice seeds per acre of seedling field is uniformly sown; the seedling field is covered with plastic film, and the film is removed after 20 days , Let the seedlings ventilate;

Abstract

The invention discloses a rice planting method which comprises seed soaking, seedling raising, seedling transplanting, additional fertilizer application, field management and harvesting. According to the planting method, a rice seedling raising method, an additional fertilizer application method, a field management method and the like are optimized, so that the rice yield is improved.

Description

Technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting rice. Background technique [0002] By promoting the hybrid rice produced by Academician Yuan Longping, it has not only solved the food for China, which accounts for a quarter of the world's population, but also solved the "bottleneck" that is difficult to increase the output of many rice-growing countries in the world, thus greatly helping alleviate the world food crisis. [0003] This is a welcome progress, but with the increase of our population, the reduction of cultivated land, the small scale of production, the shortage of water resources, the threat of drought, and the advancement of returning farmland to forests and other issues have objectively aggravated the contradiction in food demand. This, coupled with my country's relatively backward technology and weak service system, also shows that there are still various hidden dangers and risks in my country's curre...
