益果灵在滇中茄子上的应用效果

Study on the Application Effect of Yiguoling in Eggplant of Middle Yunnan

[目的]找出益果灵在滇中茄子上应用的最佳使用量。[方法]在茄杂1号上分别喷施0、0.5、1.0、1.52、.0 ml/L的益果灵,研究益果灵在滇中茄子上的应用效果。[结果]茄子产量与益果灵浓度之间具有极显著的回归关系,益果灵浓度为1.09 ml/L时,茄子的产量最高,达70 134.30 kg/hm2,增产率为50.55%。益果灵浓度为1.0 ml/L时,黄萎病发生率最低,为8.73%,其发生率比对照减低57.35%。益果灵浓度为0.5 ml/L时,茄子的日增重最大,达7.74 g/d,日增重差异率为34.38%。[结论]益果灵可以增加茄子产量,减少黄萎病发生,增加茄子的日增重。

[Objective] The research aimed to find out the optimum application amount of Yiguoling in eggplant in middle Yunnan.[Method] Yiguoling with the concn.of 0,0.5,1.0,1.5 and 2.0 ml/L were sprayed on Qieza No.1 to study the application effect of Yiguoling on eggplant of in middle Yunnan.[Result] The eggplant yield had an extremely significant regression correlation with the concn.of Yiguoling.When Yiguoling was 1.09 ml/L,the eggplant yield was highest and reached 70 134.30 kg/hm^2,with the yield increase rate of 50.55%.When Yiguoling was 1 ml/L,the occurrence rate of verticillium wilt was lowest（8.73%） and was 57.35% lower than CK.When Yiguoling was 0.5 ml/L,the daily weight gain was most（7.74 g/d） and the difference rate of daily weight gain was 34.38%.[Conclusion] Yiguoling could increase the yield of eggplant,reduce the occurrence of verticillium wilt and increase the daily weight gain of eggplant.
