Analysis on the Occurrence and Its Influencing Factors of Tea Blister Blight in Lishui City
摘要
Abstract
The occurrence of tea blister blight in Liushui city was first observed in the fall of 2010. Later, the pathogen for tea blister blight was confirmed by combination of fungal morphological characters and inoculation testing. The disease resistance to host plants showed that different cultivars of tea plant demonstrated distinctively different resistance, and the cv. Yingshuang showed most susceptible to the disease. Also, disease occurrence had a close relation with rainfall in the two periods, i.e. from April to June and August to October. In terms with altitude scope from 260 to 520 meters above sea level, different altitude had various rain days, rainfall and humidity through which the disease occurrence can be often affected. Additionally, the shade degree in tea garden was also closely related to the disease severity. Result showed that 60% of shade degree was the most favorable situation for the disease occurrence. After the end of growing season, some agricultural measures could be scientifically taken, such as pruning the diseased leaves and taking them away as well as cleaning and closing tea gardens, through which control effect can reach up to 28.86%~49.62%.关键词
