Rice continuous cropping disease-resistant yield increase agent

Abstract

The invention discloses a rice continuous cropping disease-resistant yield increase agent and relates to a high-yield rice cultivation technology. The rice continuous cropping disease-resistant yield increase agent comprises the raw materials in parts by weight; 30-35 parts of turf, 30-35 parts of biogas residues, 15-20 parts of ammonium humate, 5-8 parts of sodium silicate, 1-3 parts of magnesium amino acid chelate, 1-3 parts of zinc amino acid chelate, 1-3 parts of manganese amino acid chelate, 1-3 parts of boric amino acid chelate, 1-3 parts of rare earth nitrate, 0.5-3 parts of dicyandiamide, 1-3 parts of polyaspartic acid, 1-2 parts of bacillus subtilis, 1-2 parts of verticillium chlamydosporium and 0.5-2 parts of quercitrin. The rice continuous cropping disease-resistant yield increase agent has the beneficial effects that the feeding amounts of organic fertilizers and organic matters are greatly increased, and medium elements and trace elements are comprehensively supplemented; a proper amount of agricultural rare earth is applied, and the soil nutrition environment is improved; sodium silicate serving as a lodging-resistant agent, dichloramine serving as a nitrogen solidifier and the polyaspartic acid serving as an activation growth promoting agent are used; meanwhile, microbial agents such as the bacillus subtilis and the verticillium chlamydosporium are applied, and an insecticide such as the quercitrin is also applied, so that the continuous cropping diseases of rice can be comprehensively treated, and the aims of rice continuous cropping disease resistance, high quality and high yield are fulfilled.

Description

Technical field: [0001] The invention relates to a high-yield cultivation technique of rice, and mainly relates to a disease-resistant and yield-increasing agent for continuous cropping of rice. Background technique: [0002] Due to the growth characteristics of rice and the harsh requirements on the environment and the lack of arable land, there is a serious problem of repeated cropping in rice cultivation. As a result, the soil fertility and nutrients are short and unbalanced, and rice production is reduced. However, most farmers simply attributed it to the lack of soil fertilizer, and then applied a large amount of common chemical fertilizers such as nitrogen, phosphorus, and potassium. As a result, the middle and trace elements and beneficial elements required by rice in the paddy field were extremely deficient, destroying the soil aggregate structure and limiting With the growth and development of rice, the soil gradually changed from bacterial type to fungal type, and...

Problems solved by technology

As a result, the soil fertility and nutrients are short and unbalanced, and rice production is reduced.

However, most farmers simply attributed it to the lack of soil fertilizer, and then applied a large amount of common chemical fertilizers such as nitrogen, phosphorus, and potassium. As a result, the middle and trace elements and beneficial elements required by rice in the paddy field were extremely deficient, destroying the soil aggregate structure and limiting With the growth and development of rice, the soil gradually changed from bacterial to fungal, and the soil environment gradually deteriorated.

Moreover, due to repeated cropping, soil diseases and insect pests, especially rhizosphere nematodes, and other pests and diseases have become more and more frequent, and the beneficial bacteria in the soil have become less and weaker, which has aggravated the increase in the secretion of toxins from the roots of crops and the accumulation of root self-toxicity, etc., which fully affects the healthy growth of rice. , leading to a reduction in rice production and poor quality
