Method for preventing and removing weedy rice and weed in direct seeding and interplanting paddy field

Abstract

The invention relates to a method for preventing and removing rice weeds and weeds in direct seeding and interplanting seeding paddy, which pertains to a technical field of plant protection. The invention is mainly characterized in that: rice weed seeds and weed seeds left during direct seeding and interplanting seeding of last year are induced to grow; after former planted paddy is harvested, Glyphosate, a spray sterilant herbicide, is employed to prevent rice weeds and weeds, and solving the problem of incapability of removing older green weeds left during former planting paddy in direct seeding and interplanting seeding paddy; meanwhile, the Glyphosate has no effect on germination and growth of planted rice seeds and is environment friendly. The method for preventing and removing of the invention overcomes the shortages of incapability of employing chemical herbicides to remove rice weeds, worse and worse influence to normal direct seeding paddy, interplanting seeds, etc., and even destruction of cultivation and repeated displanting. The method for preventing and removing is in favor of paddy production in direct seeding and interplanting seeding and has significant social benefits.

Description

technical field [0001] The invention relates to a method for preventing and eliminating weedy rice and weeds in direct-seeding and inter-sowing paddy fields, and belongs to the technical field of plant protection. technical background [0002] Weedyrice (Weedyrice), also known as red rice, is a non-cultivated rice variety that is different from conventional rice with low purity or unstable varieties. It grows fast and affects the growth and development of conventionally cultivated japonica rice and the quality of rice like weeds. It is harmful to the rice fields in dozens of countries in the world, especially the direct-directed rice fields. In recent years, the damage of weedy rice has been found in all rice cultivation methods, especially in japonica rice fields with light cultivation techniques such as direct-seeding rice and inter-sowing rice, which save labor and increase income, and the incidence and damage of weedy rice are increasing. The bigger it is, some farmers ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for preventing and controlling weedy rice and weeds in direct-seeding and inter-sowing paddy fields, to solve the problem of older green weeds left over in the existing direct-seeding rice and inter-sowing paddy fields and the previous stubble of inter-sowing paddy fields. The hazards of normal direct-seeding rice and inter-sowing rice and other japonica rice production are becoming more and more serious, and even the plowing is destroyed and replanted without effective chemical control. Through the control method of the present invention, the production of japonica rice has little harm and weedy rice is less harmful. Normal emergence and growth, no pollution to the environment, is conducive to the production of rice such as direct-seeding rice and inter-sowing rice, so as to increase production and income, and increase farmers' income
