A kind of flooded rice direct-seeding planting method

Abstract

The invention discloses a flooded rice direct seeding planting method, which belongs to the field of rice planting. The method includes soil preparation before sowing, seed selection, weed control, sowing rate calculation, germination acceleration, sowing, water management, fertilizer management, and pest control. It mainly includes the following steps: pre-sowing treatment, including field surface finishing, ditching the whole box; selecting rice materials with a germination rate of more than 80%, and accelerating the germination until the chest is white for later use; keeping the box surface flooded after sowing, and the flooding depth is 3 ‑5cm; Drain the water layer on the compartment surface after the three-leaf one-heart stage, and keep water in the ditch. Shallow water irrigation was maintained on the compartment surface during the tillering stage, heading stage, and filling stage. The invention can effectively improve the seedling emergence rate and seedling rate of direct-directed rice, provide guarantee for direct-directed rice "one-sow all seedlings", is beneficial to high and stable yield of direct-directed rice, and can solve direct-directed rice bird damage, rodent damage, weed damage, Local high temperature and waterlogging lead to problems such as seedling burning, which provides theoretical basis and technical reference for the large-scale promotion and application of direct-seeding rice.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a flooded direct seeding planting method for rice. Background technique [0002] With the large-scale transfer of rural labor force of appropriate age, the number and quality of rice production employees are declining, and rice production is more inclined to adopt light, simple and efficient rice farming methods. Due to its good social, economic and environmental benefits, rice direct seeding technology has not been promoted in recent years. At present, dry live broadcast and wet live broadcast are mainly used for live broadcast in production. However, there are still problems to be solved in direct seeding rice, such as serious grass damage, rodent damage and bird damage at the seedling stage. The high temperature of accumulated water in the small concave surface of the direct seeding rice field causes the seedlings to burn, and the heavy rainfall during the sowing period causes th...

AI Technical Summary

Problems solved by technology

This method can effectively solve the problem of weed damage, rodent damage and bird damage after sowing of direct-broadcast rice, high water temperature in the small depression on the surface of the direct-broadcast rice field leads to burning seedlings, and heavy rainfall during the sowing period causes seeds to be washed and accumulated, etc. (especially in Guangdong Province), Lead to problems such as low germination rate and seedling rate
