Rice-grass carp symbiotic insect-killing breeding method

Abstract

The invention discloses a rice-grass carp symbiotic insect-killing breeding method. The method comprises the following steps: (1) preparation of a a step of deep ploughing soil with a depth of 40 to 60 cm, applying a base fertilizer, and applying a decomposed miscellaneous fertilizer and composted human and animal manure per mu; (2) seedling raising: a step of carrying out shallow-water moisturizing before seedlings completely emerge, carrying out frequent shallow-water irrigation after the seedlings emerge, applying a mixture of an antagonistic bacteria fermentation broth and tricyclazole, mixing 45 kg of water, carrying out rapid and fine spraying with the mixed solution, and dwarfing the seedlings; and (3) pest and disease control: a step of wrapping the seedling root part of a nonglutinous rice combination through a cover before placing 200 grass carps into the seedling field, and carrying out foliage spraying with the mixture of the antagonistic bacteria fermentation broth and tricyclazole. According to the invention, in the process of seedling raising, rice blast of the seedlings is prevented through the mixture of the antagonistic bacteria fermentation broth and tricyclazole; meanwhile, the grass carp can eat insect eggs in a rice field, so a symbiotic state is achieved, and the insect eggs are effectively utilized; and the mixture of the antagonistic bacteria fermentation broth and tricyclazole has strong insecticidal effect and strong persistence.

Description

technical field [0001] The invention belongs to the technical field of rice planting methods, and in particular relates to a symbiotic and deworming breeding method for rice, grass and carp. Background technique [0002] And now rice blast is one of the important diseases of rice. This disease can cause a large reduction in rice yield, and in severe cases, the yield can be reduced by 40%, or even no harvest. At present, planting disease-resistant varieties is the most economical and effective measure to prevent and control this disease. However, there are few disease-resistant varieties in production, and many disease-resistant varieties lose their resistance after 3 to 5 years of popularization and planting. [0003] In order to solve the above technical problems, Chinese patent CN105850623 provides a rice cultivation method, including making seedlings to be transplanted; plowing and fertilizing management; transplanting and planting; field fertilization management and othe...
