Paddy rice planting method

Abstract

The invention relates to the technical field of paddy rice planting methods. The paddy rice planting method comprises the following steps of: 1) raising cow hair seedlings without fertilization; 2) applying little fertilizer to obtain few branches of grain seedlings in the early period; 3) applying enough fertilizer in the medium and later periods; and 4) carrying out a culture management method of promoting yield and strengthening an insect and disease resistance effect through heavy growth and scientific and little irrigation in the later period. The paddy rice planting method has the advantages that the non-fertilized cow hair paddy rice seedlings provided by the invention have few branches because little fertilizer is applied in the early period and grow prosperously through enough fertilizer and scientific and little irrigation in the medium and later periods so as to remarkably improve the yield; and the paddy rice planting method is a new culture management method which negates a conventional culture management method which advocates culture of strong seedlings as half standing grains, sufficient ground fertilizer application, heavy tillering fertilization in the early period and 70 percents of total fertilizer amount applied in the early period of standing grains.

Description

technical field [0001] The present invention relates to the technical field of rice planting methods. 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 current food problem that cann...

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.
