摘　　要：通过分析姜瘟病发生时间与当时气候因素(温度、降雨量)的相关性,确定姜瘟病防控关键时期。选取市场上常用于防治姜瘟病的几种药剂进行田间药效试验,以筛选最佳药剂。经多年的试验示范,筛选出了对姜瘟病具有较好防治效果的药剂——枯草芽孢杆菌、荧光假单胞菌、20%噻菌铜悬浮液、46%氢氧化铜分散剂。并提炼出一套较完整的姜瘟病综合防治方法,防治效果显著。By analyzing the correlation between the occurrence time of ginger bacterial wilt and the climatic factors (temperature, rainfall) at that time, the key period of ginger bacterial wilt prevention and control was determined. In order to screen out the best agents, several biological and chemical agents commonly used in the market to control ginger blast were selected for field efficacy test. After many years of experiment and demonstration, some agents with good control effect on ginger bacterial wilt were screened out, including Bacillus subtilis, Pseudomonas fluorescens, 20% thiediazole copper suspension and 46% copper hydroxide dispersant. A complete set of comprehensive control methods for ginger bacterial wilt was extracted, and the control effect was remarkable.
