High-yield rice planting method for controlling diseases, insect pests and weeds of rice fields

Abstract

The invention provides a high-yield rice planting method for controlling diseases, insect pests and weeds of rice fields. The high-yield rice planting method includes the following steps that 1, seed pretreatment, 2 rice field transformation, 3 soil turning and fertilization, 4 seedling raising, 5 seedling transplanting, 6 fry putting, 7 topdressing and 8 harvesting. According to the planting method, rice planting and rice field fish farming are organically combined, the utilization rate of rice fields is improved, good conditions are created for rice growth, the seed processing step is increased for seed sterilization and disinfection, bacterial breeding is effectively prevented, and the method is conducive to the healthy rice growth. In addition, seeds are soaked with sodium selenite to increase the selenium content in the rice seeds, a selenium-rich slow-release organic fertilizer is applied in the rice fields, organic and inorganic fertilizers are combined to protect rice field soil and improve the nutrient element content of the soil, and microbial strains and fungicides contained in the fertilizers combine to improve the disease preventing capability of the rice field and ensure the healthy growth of fish, the production costs are low, and the high-yield rice planting method is beneficial to market promotion and has good economic benefits.

Description

technical field [0001] The invention relates to a high-yield rice planting method for controlling rice field diseases, insect pests and weeds. Background technique [0002] Rice (scientific name: Oryza sativa) is a kind of herbaceous Oryza genus, and it is also the most important and longest one as food in Oryza genus. It is also called Asian cultivated rice, and it can also be said to be rice in simple terms.

The flowers of rice are very small. When blooming, the main flowering branches will be arched, and small flowers will bloom between 30 and 50 cm below the branches. Most of them are self-pollinating and set seeds, which are called rice spikes. Generally, the size of the rice ear is 5 to 12 mm long and 2 to 3 mm thick. [0003] About half of the world's people eat rice as a staple food, especia...
