Effect of Metalaxyl-M·Hymexazol SP Mixed Fertilizer on Pepper Cottony Leak and on Pepper Plant Growth
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.
