摘要
0.3%精甲霜灵·噁霉灵可溶粉剂药肥是集杀菌剂与肥料优势于一体的产品,采用滴灌施药的方式,研究其对辣椒苗期猝倒病的防治效果和植株生长影响.结果表明:在 90 和 75 kg/hm2 滴灌施用量下,0.3%精甲霜灵·噁霉灵可溶粉剂药肥均对辣椒生长具有明显促进作用,平均株高、平均茎粗、根鲜质量、根干质量和壮苗指数均显著高于空白对照,而且促生作用优于 18.7%吡唑醚菌酯·烯酰吗啉WG 1.5 kg/hm2+水溶肥75 kg/hm2(CK3).该药肥均对苗期猝倒病具有较好的防治效果,在处理两次后,2 个施用量下的防治效果分别达到89.15%(75 kg/hm2)和89.68%(90 kg/hm2);死苗率分别为4.34%(75 kg/hm2)和4.23%(90 kg/hm2).75 和90 kg/hm2 的施用量相比较效果差异不显著,因此0.3%精甲霜灵·噁霉灵可溶粉剂药肥75 kg/hm2 的施用量符合生产上推广应用要求.
Abstract
In this paper,we used the advantages of 0.3％ metalaxyl-M·hymexazol SP mixed fertilizer controlled cottony leak in pepper in protected areas.The results showed that 0.3％metalaxyl-M·hymexazol SP mixed fertilizer 90 kg/hm2,0.3％ metalaxyl-M·hymexazol SP 75 kg/hm2 had significant promotion effect on pepper growth.0.3％ metalaxyl-M·hymexazol SP mixed fertilizer had a significant role in promoting the plant growth,plant height,stem diameter,fresh weight of root,dry weight of root,seedling index,and there was a significant difference with blank control.It also had a significant difference with 18.7％ pyraclostrobine·dimethomorph WG 1.5 kg/hm2 mixed with Water-soluble fertilizer 75 kg/hm2(CK3)in promoting the plant growth.The result of controlled cottony leak influence on plant growth showed that 0.3 metalaxyl-M·hymexazol SP mixed fertilizer had a significant role in controlling cottony leak in pepper,after two treatments,the control effects under two application rates reached respectively 89.15％(75 kg/hm2)and 89.68％(90 kg/hm2),controlled effect of mortality rate respectively were 4.34％(75kg/hm2)and 4.23％(90 kg/hm2).There was noobvious difference between 90 kg/hm2 and 75 kg/hm 20.3％ metalaxyl-M·hymexazol SP mixed fertilizer.75 kg/hm 20.3％ metalaxyl-M·hymexazol SP mixed fertilizer could be applied and extended in production.
