CURRENT SITUATION AND DEVELOPMENT TREND OF CHEMICAL WEEDING IN PADDY FIELD

ABSTRACT

Chemical weeding in paddy field is a kind of weeding method to improve rice yield and farmland management efficiency. The present situation and development trend of chemical weeding in paddy field were discussed in this paper. Firstly, the introduction introduces the definition and principle of chemical weeding in paddy field. Then, the application range of chemical weeding in agriculture of paddy field was described, and the methods and chemicals commonly used in weeding were introduced. In addition, the effect and influencing factors of chemical weeding in paddy fields were also discussed. Then, the problems of chemical weeding in paddy fields were analyzed, including the impact on the environment, ecosystem and the quality and safety of agricultural products, as well as the problem of resistance to herbicides. Finally, measures to improve chemical weeding in paddy fields were put forward, including targeted research, promotion of mechanized management technology, development of environmentally friendly herbicides and technology, and strengthening technical training and management guidance for farmers. The research in this paper can provide theoretical and practical guidance for the development of chemical weeding in paddy fields.
