| 摘 要： | 在晚稻穗期进行喷施70%丙森锌可湿性粉剂防治水稻胡麻叶斑病试验,结果表明,70%丙森锌可湿性粉剂对水稻胡麻叶斑病具有很好的防治效果。在水稻含胎期和齐穗期各喷施1次对叶片病斑和谷穗防治效果分别达94.6%和92.8%,在含胎期喷施1次对叶片病斑和谷穗防治效果分别达89.1%和79.1%。在穗期使用还能对水稻具有补锌、延迟叶片褪绿、增亮谷粒色泽、提高稻谷产量和质量的作用,在含胎期和齐穗期各喷施1次,增产率达22.05%;在含胎期喷施1次,增产率达15.55%。

| Abstract: | An experiment of spraying 70% propineb powder agent to control rice brown spot in late rice was conducted and the results show that the powder agent has a good control effect on the disease.Spray once at embryo stage and ear-ready stage has control effects of 89.1% and 79.1% at leaf spot and ear respectively.The application at ear stage can also function for zinc supplement,delay leaf green-fading,enhancing the color of grain and increasing rice yield quality.Spray once at embryo stage and ear-ready stage can increas the yield by 22.05% and spray once at embryo stage can increase the yield by 15.55%. |
