水稻病虫害综合防治技术研究 -农学专业

摘要

水稻作为全球最重要的粮食作物之一，其产量和质量直接关系到世界粮食安全。然而，病虫害的发生严重影响了水稻的稳产高产。本研究旨在构建一套科学有效的水稻病虫害综合防治技术体系，以实现绿色可持续发展为目标，通过田间试验、室内分析与模型构建相结合的方法，系统研究了主要病虫害的发生规律及其影响因素，创新性地提出了基于生态调控的综合防治策略。研究结果表明，该技术体系可有效降低稻瘟病、稻飞虱等主要病虫害的发生率，减少化学农药使用量30%以上，同时提高水稻产量8%-12%，改善稻米品质。本研究不仅为水稻安全生产提供了理论依据和技术支持，还为其他农作物病虫害防治提供了有益借鉴，对推动农业绿色发展具有重要意义。

RESEARCH ON INTEGRATED CONTROL TECHNOLOGY OF RICE PESTS AND DISEASES

ABSTRACT

Rice is one of the most important food crops in the world, and its yield and quality are directly related to the world food security. However, the occurrence of diseases and pests seriously affected the stable yield and high yield of rice. This study aims to build a scientific and effective comprehensive control technology system for rice pests and diseases. With the goal of achieving green and sustainable development, the occurrence rules and influencing factors of major pests and diseases were systematically studied through field experiments, laboratory analysis and model construction, and a comprehensive control strategy based on ecological regulation was innovatively proposed. The results show that the technology system can effectively reduce the incidence of rice blast, rice planthopper and other major diseases and pests, reduce the use of chemical pesticides by more than 30%, increase rice yield by 8% to 12%, and improve rice quality. This study not only provides theoretical basis and technical support for the safe production of rice, but also provides a useful reference for the prevention and control of diseases and pests of other crops, and has important significance for promoting the green development of agriculture.
