辣椒疫病发病主导因素及综合防治技术研究

Study on the main factors leading to the occurrence of Phytophthora capsici and its integrated control techniques

通过3a在多年辣椒重茬地的田间试验及调查研究,基本明确了辣椒疫病发生与灌水方法、栽培方式、降水、中心病株的出现等主导因素的关系。提出了栽培防病、化学治疗的综防技术,达到控病增产的目的。

Through field experiments and investigations in continuous cropping fi elds of pepper for three years, the relationship between occurrence of Phytophth ora capsici and irrigation method, culture form, precipitation, appearance of ce ntral infected plant was described. The integrated control technique including c ultural and chemical control measures was proposed. By resorting to the techniqu es, the blight can be controlled and the yield increased as well.
