【摘要】 茶白星病是高山茶园常年危害最严重的叶部真菌病害。本文通过系统调查石门茶树品种、栽培影响因素与茶白星病的关系,进一步明确茶白星病的发病率与海拔高度正相关,随种植年限延长先升后降,与品种及种植间距关系不明显。在缺乏可靠的抗病品种与生物农药下,通过茶白星病的绿色高效防控保障茶叶生产安全,只有弱化高山茶白星病菌源充足,传播条件充分的因素,本文通过设置两个品种、修剪间隔时间年限达3年的定点实验,结果显示,栽培技术成了高山茶树的绿色防控关键点,纯采名优茶高山茶园可通过每2年5-7月份一次茶园深修剪,保障春茶的产量与品质。更多还原

【Abstract】 Tea white scab is the most serious fungal leaves disease happened on high mountain tea garden throughout the year. In this paper, We further make clear that incidence rate of the tea white scab and altitude highly positively correlated, first increased and then decreased with increasing years of planting, with no obvious relationship of planting varieties and plant spacing by the system investigation of Shimen tea varieties, cultivation factors and tea white scab relationship, In the absence of resistant varieties and biological pesticide reliability, the safety and security through effective protecting tea white scab was attained only by weaking the factors of high mountain tea white spot source sufficient and propagation conditions fully, this paper set up two varieties, Pruning interval period field experiments for 3 years, We find that cultivation technology is the key control point to protect tea white scab in high mountain, Through every 2 years 5-7 month a tea deep pruning, tea mountain tea produced can guarantee the yield and quality of tea by spring tea .更多还原
