水肥管理对辣椒枯萎病发生的影响

Effects of Irrigation and Fertilizers on Fusarium Wilt

利用正交试验研究了水肥管理对辣椒枯萎病发生的影响。结果表明灌水和施肥是影响辣椒枯萎病发病率的主要因素。为防止辣椒枯萎病的发生,应注意控制水肥,减少病菌通过水分传播,促进辣椒根系发育,增强抗病能力。

In the paper the relation between imgation and fertilization was studied by means of the orthogonal design. The result showed that irrigation and fertilization were mostly effect factors on the control of fusarium wilt. In order to prevent fusarium wilt, the irrigation and fertilization should be cont.rolled so that the transmission way of disease germ was reduced through water, the development of capsicum root was accelerated and the capability of resistance to disease was enhanced.
