本文采用检查田间病情,观察病斑产生分生孢子的动态;并结合捕捉到的空中孢子浮游数量,参考气象预测,分析其与大田盛发流行的病情消长规律的关系,初步提出了浙贝母灰霉病的预测预报技术及病情的防治指标,经三年实践,有较大可行性。 In this paper, field conditions were examined to observe the dynamics of the conidia produced by the lesions. Combined with the number of airborne spores captured, the weather forecast was used to analyze the relationship between the disease and the epidemic of Daejeon. A preliminary proposal was made for Fritillaria. The prediction and forecasting technology of gray mold and the disease prevention and control indicators are more feasible after three years of practice.
