Method for planting high-yield paddy rice

Abstract

The invention relates to a method for planting high-yield paddy rice. The method is a cultivation management method, which is used for promoting yield increase and enhancing pest resisting and disease resisting effects, and comprises the following steps: (1) not fertilizing rice seedlings, so as to obtain cowhair seedlings; (2) fertilizing a small amount of fertilizer at an early stage of the rice seedling, so as to obtain a small number of branches; (3) applying a sufficient amount of fertilizer at medium and later stages; and (4) scientifically carrying out seldom irrigation at the vigorous-growth later stage. The fertilizer used for fertilizing contains the following ingredients in parts by weight: 1-5 parts of urea, 9-13 parts of boric acid, 5-7 parts of potassium carbonate, 10-15 parts of methylene succinate, 3-5 parts of trace elements and 1-3 parts of growth regulator. The method is a novel cultivation management method, which is used for promoting obvious yield increase, and comprises the following steps of not fertilizing the rice seedlings so as to obtain the cowhair seedlings, fertilizing a small amount of fertilizer at the early stage of the rice seedling so as to obtain a small number of branches, applying a sufficient amount of fertilizer at the medium and later stages, and scientifically carrying out seldom irrigation at the vigorous-growth later stage. The conventional cultivation management method that strong seedlings are cultivated and are equal to half of rice high-yield, a sufficient amount of base fertilizer is applied, a tiller fertilizer is heavily applied at the early stage, and 70% of the total amount of fertilizer is applied at the early stage of the rice seedlings is negated.

Description

technical field [0001] The invention relates to the field of crop planting, in particular to a high-yield rice planting method. 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's cu...

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 genetic modification that we rely on now can change the quality and character of rice, but it cannot increase the yield of crops. At the same time, because the price of genetically modified 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 law of planting from planting experience to increase grain production.
