种衣营养剂与土壤改良剂处理瓜类种子对农药减量的影响

Effects of Seed Coating Nutrient and Soil Amendment on Pesticide Reduction of CucurbitsSeeds

为解决瓜类作物生产中农药用量过大,促进农药使用量负增长目标的实现,通过种衣营养剂处理瓜类作物种子,以及土壤改良剂改良土壤试验,探索种衣营养剂与土壤改良剂处理对瓜类作物农药减量控害的方法。结果表明,种衣营养剂对丝瓜种子安全,不会影响丝瓜的移栽成活率,且正常施药及农药减量10%可明显增加丝瓜产量,不影响美洲斑潜蝇防治效果,有效减轻丝瓜霜霉病发病,提高防治效果。综上所述,种衣营养剂与土壤改良剂处理农药可以减量10%。

In order to solve the problem of excessive use of pesticides in the production of cucurbit crops and promote the realization of the goal of negative growth of pesticide use,the seeds of cucurbit crops were treated with seed coating nutrition agent,and the soil was improved by soil amendment.The method of reducing and controlling the pesticide use of cucurbit crops by seed coating nutrition agent and soil amendment treatment was explored.The results showed that the seed coating nutrition agent was safe for luffa seeds and would not affect the transplanting survival rate of luffa.The normal application and 10%reduction of pesticide could significantly increase the yield of luffa,not affect the control effect of Liriomyzasativae,effectively reduce the incidence of downy mildew of luffa and improve the control effect.In summary,seed coating nutrients and soil amendments can reduce the amount of pesticides by 10%.
