摘要
为探究土壤熏蒸剂在露地生产中对大白菜根肿病的防治效果,以胶白1号为试材,研究了98%棉隆微粒剂配施微生物土壤修复剂对大白菜根肿病的防效以及对土壤性质的影响。结果表明:98%棉隆微粒剂、20%氰氨化钙颗粒剂配施微生物土壤修复剂对大白菜根肿病均具有良好的防病促生效果,收获期发病率、病情指数均显著低于对照,防治效果分别为73.26%和74.42%;净菜产量显著高于对照,分别比对照增产43.41%和59.51%;对土壤微生物数量无显著影响,但对土壤理化性质有一定的影响,具有改土作用。
In order to explore the control effect of soil fumigant on Chinese cabbage clubroot in open field production,‘Jiaobai No.1’was taken as test material to study the control effect of 98% dazomet micro granule combined with microbial soil remediation agent on Chinese cabbage clubroot and effect on soil properties.The results showed that 98% dazomet micro granule,20%calcium cyanamide granule combined with microbial soil remediation agent all had good disease control effects and growth promotion result.The morbidity and disease index at harvest stage both were significantly inferior to that of the contrast.The control effects were 73.26% and 74.42%,respectively.The net vegetable yields were significantly higher than that of contrast,43.41%and 59.51%higher than that of the contrast,respectively.There was no significant effect on soil microbial number,but has certain effect on soil physical and chemical properties,which has soil improvement effect.
