植物免疫诱抗剂维大力对水稻抗病及产量的影响
Effects of Plant Immune Elicitor VDAL on Disease Resistance and Yield of Rice
摘要
Abstract
In order to further verify the efficacy of VDAL on rice yield and disease resistance,and provide scientific basis for its popularization and application in rice production,different application time(before sowing stage,rice seedling stage,rice burst stage,rice full heading stage)and different application methods(seed dressing,stem and leaf spray)were set.The results indicated that the disease index of rice sheath blight treated with different treatments were significantly lower than that of clean water control.The best control effect of rice blast was seed dressing+spraying at rice burst stage+spraying at full heading stage,and the control effect of diseased fingers reached 76.53%.At the same time,this treatment combination also showed the most significant improvement in rice yield,with an increase of 13.27%.The effects of different treatments on characters of rice plants were significantly different.Therefore,in rice production,it is recommended to use VDAL for seed dressing,and spray 150 g/hm2 of stems and leaves at rice burst stage and full heading stage.关键词
