Weed prevention and control method used in organic rice planting process

Abstract

The invention discloses a weed prevention and control method used in the organic rice planting process. The weed prevention and control method used in the organic rice planting process is low in cost, good in effect, truly free of toxin and damage and practical. The method is characterized that a rice seedling bed is irrigated 7-10 days after rice seedlings are transplanted, deep water weed control is achieved, the weed control water level is kept to be 55-65% of the height of the rice seedlings, and the water level is kept continuously for 8-10 days and nights; during the time from transplanting of the rice seedlings to water treatment, the water level is kept in the field, soil can not be exposed, and growth of weeds and weed seeds is inhibited or the weeds and the weed seeds are dead under the condition that oxygen and sunlight irradiation lack. The method is low in implementation cost, good in weed prevention and control effect and very beneficial to later growth of rice. The method solves the problems which farmers long to solve all the time but are not solved in the organic rice planting process, and has an important promoting significance in planting of organic rice.

Description

technical field [0001] The invention belongs to the technical field of crop planting, specifically, the technology is a method for controlling the growth of weeds and eliminating weeds during the planting process of organic rice. Background technique [0002] Organic rice production refers to a production system that does not use chemically synthesized fertilizers, pesticides, growth regulators and other substances during the entire growth period of rice, nor does it use genetically engineered organisms and their products. Its core is to establish and restore a virtuous circle of agricultural ecosystems to maintain the sustainable development of agriculture. Organic rice production is to improve soil fertility through the use of organic fertilizers and appropriate farming and breeding measures, and to control diseases, insects, and weeds through natural methods, such as reasonable crop rotation, agricultural control, biological pest control, and protection of natural enemies...

AI Technical Summary

Problems solved by technology

In the process of planting organic rice, there is no effective way to control the growth of weeds and eliminate weeds. If weeds are not eliminated in time, weeds will compete with rice for fertilizer and sunlight, affecting the yield and quality of rice. The seriousness is getting worse year by year, and finally lead to the use of herbicides in this field, and the rice grown is not organic

In the case where herbicides cannot be used, in many cases only the method of manual weeding can be used

However, manual weeding has low efficiency, high labor intensity and difficult working conditions
