采用室内和室外小区、大区试验的方法，测定了四川省农科院植保所研制的药肥复合型棉花种衣剂防治棉苗病害及其对棉花生长、产量的效应。结果表明，种衣剂２号对防治棉花播后烂种和苗床期由立枯病、猝倒病引起的死苗具有特效，１９９５～１９９６年大区对比试验显示，种衣剂防治立枯病、猝倒病死苗的效果为９０．７１～９６．４３％，并能提高棉花的出苗率，促进棉苗生长，增强抗逆能力，种衣剂处理棉花每公顷平均成株数、蕾铃数均比对照高，平均增产皮棉７．５６％。
The method of indoor and outdoor community and large area test was used to determine the effect of compound fertilizer on cotton seedling disease prevention and control on the growth and yield of cotton by the plant protection institute of Sichuan Academy of Agricultural Sciences. The results showed that the seed coating agent No. 2 had special effects on the dead seedlings caused by rotten cotton seeds and seedling beds caused by damping-off and damping-off disease. From 1995 to 1996, the comparative tests showed that the seed coating agents were effective against blight , The damping-off effect of diseased seedlings was 90.71 ~ 96.43%, and it could improve the emergence rate of cotton, promote the growth of cotton seedlings and enhance the resilience, the average number of plants per hectare treated by seed coating agent, Higher than the control, the average yield of lint 7.56%.
