A kind of paddy rice organic cultivation field weeding method

Abstract

The invention discloses a field weeding method for the organic cultivation of paddy rice. The method comprises the steps of preparing soil, nursing seedlings, transplanting, applying fertilizer, managing water and fertilizer, and applying organic manure before the transplanting of rice seedlings, i.e. forming a surface restoration layer; after the transplanting of the rice seedlings, applying biogas slurry to form a 4-5cm biogas water layer; and by the adoption of sparse seeding, earlier-stage promotion and later-stage control, implementing watering and fertilization at the two-leave one-heart stage, and controlling fertilizer and water at the later stage. From the point of ecology, the method realizes the purpose of preventing and eradicating field weeds by organically combining the application of the biogas slurry and the organic manure according to the biological characteristics of the paddy field weeds and the paddy rice, and has the advantages of ecosystem, environmental protection and the like as a paddy field weeding method which is good in weeding effect, cost-saving, yield-enhancing, effect-enhancing, simple and easy, thereby having important significances to the organic production of paddy rice in China.

Description

technical field [0001] The invention relates to a field weeding method for organic rice cultivation. Background technique [0002] China is a big country of rice production and consumption, and more than 60% of the population takes rice as the staple food. Therefore, the quality and safety of rice products have always been the focus of attention. At the end of the 20th century, in order to meet the market's demand for high-quality and safe rice, the organic rice industry developed rapidly in China and gradually developed into a new industry. Organic rice refers to the use of chemical fertilizers, pesticides, growth regulators and other substances in the production process, and does not use genetically modified technology and its products. Rice grown using sustainable agricultural techniques. Paddy field weeds are plants that directly or indirectly interfere with the growth of rice in the specific growth environment of rice. They will directly affect the growth and yield of...

AI Technical Summary

Problems solved by technology

There are many studies on the effect of biogas slurry application on the growth and development of rice, but there is no report on the effect of weeding on paddy fields

[0007] The traditional dry-raised long-age seedlings adopt the technical measures of "pre-control and post-promotion". In order to control the excessive growth of seedlings, excessive fertilizer and water control is carried out in the early stage, which leads to the aging of seedling tissues and the formation of pimple seedlings. In the later stage, in order to promote growth , carry out fertilization and water attack, the new stems and leaves are tender, the tissue is not sufficient, the cells are saturated with water, the greening is slow after transplanting, the roots are late and tillering is delayed, which affects growth

The traditional method of applying manure is to spread it after transplanting. This method must process the organic fertilizer into granules, etc., which greatly increases the cost
