“庄福星”防治油菜根肿病的效果研究

Control Effect of 'Zhuangfuxing' on Rape Clubroot Disease

[目的]评价"庄福星"对油菜根肿病的防治效果及对油菜的增产效果。[方法]研究了在移栽和直播2种不同栽培方式下"庄福星"对油菜根肿病的防治效果及对油菜产量的影响。[结果]"庄福星"在油菜苗期能够降低发病率6%～8%,在抽薹-初花期能够降低发病率6%～10%,在成熟期能够降低发病率4%～6%;"庄福星"能够有效促进油菜开花结实,使其形成较多的单株有效分支数,延长主花序长度,增加单株有效角果数和每角果粒数;"庄福星"在移栽田中的增产效果明显优于直播田。[结论]"庄福星"能够降低油菜根肿病的危害程度并具有明显的增产效果。

[Objective] The aim was to evaluate the control effect of ’Zhuangfuxing’ on rape clubroot disease and the yield-increasing effect of rape.[Method] The control effect of ’Zhuangfuxing’ on rape clubroot disease and the yield-increasing effect of rape were studied under two different cultivation patterns of transplanting and direct seeding.[Result] ’Zhuangfuxing’ could decrease the incidence of 6%-8% at rape seedling stage,the incidence of 6%-10% at bolting and initial flowering stage and the incidence of 4%-6% at mature stage.’Zhuangfuxing’ could effectively promote the flowering and seed setting of rape,forming more individual effective branch,prolong the length of main inflorescence,and increase individual effective silique and seed number per pod.The yield-increasing effect of ’Zhuangfuxing’ in transplanting field was obviously better than that in direct seeding field.[Conclusion] ’Zhuangfuxing’ could decrease the damage degree of rape clubroot disease and obviously increase the yield of rape.
