最近在一些管理粗放、阴湿坡地老茶园中发现大多数茶树上长有寄生植物苔藓和地衣。这类以风为传播媒介的寄生植物在10℃以上开始发生,3～6月是寄生植物繁殖的高峰期,干旱高温时发生缓慢,冬季停止生长。这类寄生植物附生在茶树枝干上,吸取茶树体内的养料和水分,严重影响茶树的正常生长发育,使茶叶的产量、质量明显下降、同时苔藓和地衣是茶树病虫害潜伏越冬的极好场所,苦不及时防除,将会使茶树衰枯死亡,防治方法如下:1.以防为主。根据苔藓、地衣传播蔓延的特点和发生条件,对其 Recently, in some old tea farms with extensive and shady slopes, most of the tea trees are found with moss and lichens of parasitic plants. Such wind-borne parasitic plants begin to occur above 10 ° C. From March to June is the peak of parasitic plant propagation. Drought occurs slowly at high temperatures and stops growing in winter. Such parasitic plants attached to the stems of tea, tea plant absorption of nutrients and water, seriously affecting the normal growth and development of tea, so that the yield and quality of tea decreased significantly, while moss and lichen is an excellent place for tea plant diseases and insect pests lurking overwintering , Bitter not timely control, will make the tea tree died of death, control methods are as follows: 1. To prevent the main. According to the characteristics of lichens, lichens spread spread and its occurrence on it
