摘要
2019年,在甘肃省岷县,选用98%棉隆GR 225~450 kg/hm^(2)不同施用量,开展当归育苗田土壤消毒对有害生物及当归苗相关性状的影响试验。结果发现:与空白对照相比较,不同施用量对株高有促进作用。有害生物终期防效调查发现,对地下害虫防效100%;对麻口病防效50.00%~69.30%;对田间杂草防效62.39%~83.28%。综合投资效益比较,建议在今后当归田育苗中选用98%棉隆GR 375 kg/hm^(2)施用量,具有较好的提高种苗质量和单位效益的作用。
Field experiment was conducted to investigate the effect of dazomet 98%GR at different dosages to soil borne pests,agronomic and economical characters of angelica seedling in Minxian,Gansu province in 2019.The results showed that dazomet 98%GR at 225-450 kg/hm^(2) had promotion on plant height.The control efficacy against soil borne insect pests was 100%,50.00%-69.30%to Chinese angelica coarse bark disease at seedling stage,and 62.39%-83.28%to weeds.According to comprehensive analysis,dazomet 98%GR at 375 kg/hm^(2) is recommended to be applied on angelica seedling in future.
