利川猫湾茶叶病虫害绿色防控模式
摘要：通过2016年4月28日的试验，绿色防控模式（30%茶皂素300倍稀释液+调节剂B型750倍稀释液+3%多抗霉素750倍稀释液）对茶园主要病虫害防治效果分别较常规防控模式（30%唑虫酰胺1 000倍稀释液+25%戊唑醇800倍稀释液）高9.9、13.0、10.3个百分点；经7月26日调查，绿色防控模式对茶园主要病虫害控制效果与常规防控模式相比，害虫减少75.8%，病害降低了85.2%，且保护了天敌，3种天敌数量是常规防控模式的2.3倍；經9月25日调查，以常规防控模式为对照，绿色防控模式对茶小绿叶蝉、茶尺蠖、茶枝梢黑点病、茶饼病的防控效果分别为62.5%、85.9%、90.3%、29.6%。

Abstract： Through the experiment in April 28th，2016，the control effects of green prevention control mode（30% of tea saponin 300 times diluent+regulator type B 750 times dilution+3% called 750 times diluent）on the main extermination of disease and insect pest of tea garden was higher than that of the conventional prevention control mode（30% azole amide 1 000 times diluent+25% tebuconazole 800 times diluent）， the higher percent point were 9.9，13.0，10.3，respectively. Through the investigation in July 26th，compared with the conventional prevention control mode on the main extermination of disease and insect pest of tea garden， the green prevention control made pests decreased by 75.8%，the disease reduced by 85.2%，and the number of protected natural enemies was 2.3 times than that of the conventional prevention control model. Through the investigation in September 25th，contrast with conventional control model，the control effects of the green prevention control model on tea lesser leafhopper，tea geometrid，tea branches black-dot disease and tea gall were 62.5%，85.9%，90.3%，29.6%，respect...
