摘要
对上海地区近年来优质水稻病虫害绿色防控技术的研究现状进行总结。结果表明,采用农业、生物防治配以化学防治或选用稻田生态种养配以物理和生物防治的水稻绿色防控措施,病虫害的防控效果与常规化防相当。同时,实施绿色防控的核心区和示范区稻田生态群落得到明显改善,天敌数量显著增加,生长季水稻用药次数和用药量也明显减少,用药量比常规化学防治减少42.03%,改善了生态环境和农产品安全品质。
This paper summarizes the research status of green management of high-quality rice diseases and insects in Shanghai in recent years.The results showed that the prevention and control effect of green management was similar to the normal control on the chemical agents by adopting agricultural,biological and chemical control or selecting rice field ecological cultivation combined with physical and biological control.At the same time,the ecological populations of rice fields in the core areas and demonstration areas where green prevention and control were implemented have been significantly improved,and the number of natural enemies has significantly increased,and the frequency and dosage of chemical drugs used in rice growth stages have also been significantly reduced.The amount of agents used has been reduced by 42.03%compared with traditional chemical management.Thus,the green management greatly improved the quality of the environment and the safety of agricultural products.
