Method for planting rice through waterlogged direct seeding

Abstract

The invention discloses a method for planting rice through waterlogged direct seeding, and belongs to the field of rice planting. The method comprises the steps of land preparation before seeding, seed selection, prevention and control of weeds, calculation of the seeding amount, germination accelerating, seeding, water management, fertilizer management and prevention and control of diseases and insect pests. The method mainly comprises the following steps that treatment before seeding comprises field surface finishing and ditching for compartment finishing; a rice material with a germinationrate of 80% or above is selected, and germination is accelerated until rice husks are broken and radical buds are grown for standby application; after seeding, the compartment surface is kept waterlogged, wherein the waterlogging depth is 3-5 centimeters; after a three-leaf one-core stage, a water layer of the compartment surface is drained, and it is maintained that water exists in a ditch; in atillering stage, an earing stage and a grain-filling stage, shallow-water irrigation is maintained on the compartment surface. The method can effectively increase the emergence rate and planting percent of directly seeded rice, provides a guarantee for 'one-seeding whole-seedling' of the directly seeded rice, is beneficial to the high and stable yield of the directly seeded rice, can solve the problems such as seedling burnt caused by bird damage, rat damage, crop smothering and local high-temperature waterlogging, and provides a theoretical basis and technical reference for the large-scale popularization and application of the directly seeded rice.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a flooded direct seeding planting method of rice. Background technique [0002] With the transfer of a large number of rural labor forces of the right 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 been self-promotion in recent years. At present, live broadcasting in production mainly adopts dry live broadcasting and wet live broadcasting. However, there are still problems to be solved in direct-directed rice at present, such as weed damage, rodent damage, and bird damage at the seedling stage. etc. (especially in Guangdong Province), resulting in low seedling emergence rate and seedling growth rate. These problems limit the production and popularization and applicatio...

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
