为弄清贵州省水稻病虫害专业化统防统治效果,2011年在贵州省毕节市金沙县的5个村寨进行了水稻痛虫害专业化统防统治与农民自防区防效对比试验.结果表明,与农民自防区相比,专业化统防统治区对稻瘟病、稻纵卷叶螟和稻飞虱的防治效果均达到80％以上,平均分别提高16.18％、12.52％和9.46％,差异显著.每667m2平均挽回产量损失65 kg以上,增产率18.72％以上,减少施药1.34次,减少农药量307.34g,减幅达65.86％,减少农药和劳工支出60.67元,达到了增加产量、减少防控成本投入和安全生产的效果.%To gain a clear idea of the control effect of specialized system prevention and control for rice diseases and insect pests in Guizhou, a contrast test was conducted in 2011 between the specialized system prevention and control area and farmer self-prevention areas among five villages in Guizhou. The results showed that compared to the farmer self-prevention areas, the control effect of specialized system prevention and control of rice blast, rice leaf roller and rice fulgorid reached more than 80 %, increased by 16. 18%, 12. 52% and 9. 46% respectively. The difference was significant. The average production loss retrieved was 65 kg/667mz, increased by 18.72%. Beside, the times of applying farm chemical was reduced by 1. 34, the dosage reduced by 307. 34 g with the decreasing amplitude of 65.86%. Consequently, 60. 67 Yuan of farm chemical and labor cost was saved. The results of increasing production, safe production and reducing input in prevention and control were achieved.
