摘要
[目的]研究田间绿豆晕疫病的防治方案。[方法]研究不同种衣剂和叶面肥组合对绿豆晕疫病田间防治效果和绿豆生长的影响。[结果]种衣剂拌种并喷施叶面肥对绿豆田间晕疫病的防治效果最好,病株率仅为3.0%,防治效果达91.4%,并且3组处理绿豆植株的株高、主茎分枝数、主茎节数、单株荚数、荚长、荚粒数、籽粒大小、单株粒重和百粒重等重要表型性状均高于对照组,3组处理的产量分别为1 126.20、1 213.80和1 194.60 kg/hm^2,也均显著高于对照组。[结论]种衣剂拌种和喷施叶面肥能有效控制田间绿豆晕疫病的发生和危害,提高绿豆产量。
[ Objective] To study the prevention and control programmes for halo blight of Vigna radiata L. . [ Method] To study the effect of different seed coating agent and foliar fertilizer combination on halo blight control and growth of V. radiata L. . [ Result ] The seed dressing and foliar fertilizer spraying were the best method for controlling halo blight of V. radiata L. in fie ld , the disease rate was only 3 .0 %, the controlling effect was 91.4% , the plant height, the number of main stem branch, the number of main stem nodes, the pods number per plant, pods length, seeds per pod, seed size, seed weight per plant and 100-seed weight were all higher than the control. The yield of three treat-ments were 1 126.20, 1 213. 80 and 1 194. 60 kg/hm2, respectively, which were also significantly higher than the control. [ Conclusion] Seed dressing and foliar fertilizer spraying could effectively control the occurrence and damage of halo blight of V. radiata L. and enhance the yield.
