胡椒瘟病田间发生规律观察

Study on the Field Occurrence Regularity and Chemical Control of Pepper Phytophthora Foot rot

研究胡椒瘟病的发生与气象因子、土壤pH、土壤质地、地形地势、种植年限等之间的关系。结果表明:气象因子是胡椒瘟病发生流行的主要因素;土壤pH和种植年限与病害的发生没有显著的相关性,但是土壤质地、地形地势、农业措施对病害的发生有着显著的影响。

The effect of weather condition,soil type,soil pH,plant age and landform on occurrence of the pepper Phytophthora foot rot was investigated in this paper.The results showed that the weather condition was an important effect factor to the pepper Phytophthora foot rot epidemic.The soil pH and plant age had no significant effect on the occurrence of Pepper Phytophthora foot rot.However,the soil type,landform and plant measure had effect on the occurrence of pepper Phytophthora foot rot.
