Evaluation of Control Effect of Variety,Sowing Date and Fungicide Treatment on Rape Clubroot
摘要
Abstract
In order to explore the effective control techniques and control countermeasures of rape clubroot,this study was conducted in Wuyuan County to investigate the control effects of some technical measures,such as different resistant varieties of rape,adjustment of sowing time within suitable sowing period of the same variety,application of calcium lime in diseased fields,and fungicide disinfection of rape seed-burrow soil and application of fungicide after seedling,on clubroot disease.The results showed that the field incidence rate of Huayouza 62R was 3.75%,which was significantly lower than that of more than 80%of susceptible varieties such as Ganyouza No.8,and had obvious disease resistance advantages in the prevention and control of clubroot.When the same variety of rape was sown in the same area,the disease rate in the field of delayed sowing was significantly lower than that of earlier sowing.Application of calcium lime and fungicide in diseased field could reduce the rate of diseased plant and damage loss of rape clubroot to some extent.The experiment proved that the application of resistant varieties had a unique effect on the control of clubroot.Appropriate delay of sowing in safe sowing period,application of calcium lime to reduce soil acidity in diseased fields,soil disinfection and chemical intervention at seedling stage had certain control effects on the treatment of rape clubroot.In conclusion,the application of resistant varieties,the rational arrangement of sowing date of rape varieties,the safe use of calcium lime and the early intervention of fungicides in seedling stage had superimposed effects on the integrated control of rape clubroot.关键词
