摘要：

旨在应用“三防两控”技术，实现再生稻病虫害轻简高效防治。试验设3个试验处理：“三防两控”防治处理、常规防治处理，CK（不施药），3次重复，调查不同防治处理下，再生稻病虫害发生情况，以及不同试验处理下再生稻产量和产量构成。结果表明，“三防两控”防治处理效果最佳，对再生稻头季病虫害防效在90%以上，对再生季病虫害防效在75%以上，显著优于常规防治。同时减少农药施药次数2次，减少65.0%固体剂型农药用量和46.23%液体剂型农药用量。“三防两控”防治处理下两季产量均是最高，头季产量较常规防治增产12.05%，再生季产量较常规防治增产56.37%，周年产量较常规防治增产21.14%，CK处理头季产量、再生季产量及周年产量均是最低。“三防两控”病虫害防治技术在再生稻上的应用具有高产、高效、节本、省工等特点，具有较好的应用前景。

Abstract:

The purpose of this study is to apply the technology of “three prevention and two control” to achieve the goal of simple and efficient control of diseases and pests of ratooning rice. Three treatments were set up in this experiment: “three prevention and two control” treatment, conventional control treatment, and CK (no prevention). And 3 repetitions were conducted to investigate the occurrence of diseases and pests in ratooning rice under different control treatments, as well as ratooning rice yield and yield composition. The results showed that the control effect of “three prevention and two control” was the best, and the control effect on diseases and pests in the first season of ratooning rice was more than 90%, and the control effect in the ratooning season was more than 75%, which were significantly better than those of the conventional control. At the same time, the number of pesticide application was reduced by 2 times, the application of solid pesticide and liquid pesticide was reduced by 65.0% and 46.23%, respectively. Under the “three prevention and two control” treatment, the yield of both seasons was the highest. Compared with those of conventional control, the yield of the first season was increased by 12.05%, the yield of the ratooning season was increased by 56.37%, and the annual yield was increased by 21.14%. The yield of the first season, the ratooning season and the year under the CK treatment were the lowest. The application of “three prevention and two control” technology for diseases and pests of ratooning rice has the characteristics of high yield, high efficiency, cost saving and labor saving, and has a good application prospect.
