Comprehensive control method of rice diseases, insect pests and weeds

Abstract

The invention discloses a comprehensive control method of rice diseases, insect pests and weeds. By organically combining rice planting and duck raising in a paddy field, the weeds and the insect pests in the paddy field are eaten by ducks, soil is massaged and loosened by the ducks, tillering of rice plants is stimulated, effects of muddying water and fertilizing the field are generated, effectsof killing the insect pests and the weeds are good, through a seed pretreatment step, seeds are subjected to sterilization and disinfection, bacterial breeding is effectively prevented, healthy growing of rice is facilitated, a disease control effect is good, meanwhile, the seeds are soaked in sodium selenite, thus a selenium content of the rice seeds is increased, by applying a selenium-enrichedslow-release organic fertilizer into the paddy field, a trace element content of the soil can be effectively increased, nutrient value of the soil and the rice is improved, and a rice yield per mu israised; and in the control method, selenium-enriched slow-release organic fertilizer granules are produced by means of fertilizer granulation equipment, and the selenium-enriched slow-release organicfertilizer produced by the fertilizer granulation equipment is in a shape of small granules, and thus is evenly applied during fertilization, so that growing of the rice is facilitated.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a method for comprehensive prevention and control of rice diseases, insect pests and weeds. Background technique [0002] Rice is the most important kind of food in the genus Oryza, also known as Asian cultivated rice. Rice is the main food crop in my country and one of the important commodity grains in China. With the rapid development of rice planting technology and With the continuous expansion of the planting area, rice occupies an increasingly important position in national life, and it also plays an irreplaceable role in solving my country's food supply. However, judging from the current situation of rice development, there are still some common problems in rice planting in my country, among which rice diseases, insect pests and weeds are an important reason that restricts the development of rice planting industry; [0003] Therefore, the patent application number CN20161046157...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a kind of comprehensive prevention and control method of rice diseases, insect pests and weeds: (1) by organically combining rice planting and raising ducks in paddy fields, utilizing the vigorous omnivorous and uninterrupted activities of ducks, Eat weeds, pests, massage, loosen the soil in the rice field, stimulate tillering of rice plants, produce the effect of muddy water and fertilize the field, through the seed pretreatment step, sterilize the seeds, effectively prevent the growth of bacteria, and help the healthy growth of rice. At the same time, the seeds are soaked with sodium selenite to increase the selenium content of rice seeds. By applying selenium-enriched slow-release organic fertilizers in the paddy fields, the content of soil nutrients and disease prevention capabilities in paddy fields are improved, and the fertilizer effect is long. Release agent, the fertilizer validity period can run through the rice planting all the way, only a small amount of topdressing after planting is needed to meet the needs of rice planting, effectively increase the content of trace elements in the soil, improve the nutritional value of soil and rice, the fertilizer composition is friendly to the soil, and increase the yield of rice per mu, which solves the problem The existing integrated prevention and control methods for rice diseases, insect pests and weeds are not effective in controlling rice diseases, insect pests and weeds, and have no obvious effect on increasing rice income; (2) by using fert
