第一,根据茶园亩产干茶指标确定全年每亩用氮量。据分析,每百斤干茶的原料含氮量为5～6斤,而氮的吸收率约为50%,则生产每百斤干茶需氮10～12斤,大致是一斤纯氮生产10斤干茶。但是,茶树要维持生命活动,还要长枝叶树体以及修剪消耗,实际上通常一斤纯氮只能收获干茶7斤左右(当然这受土壤肥力,土壤质地以及施肥技术等影响。因此,全年每亩用氮量,为亩产干茶

First, determine the amount of nitrogen per mu per year based on dry tea indicators of tea plantations. According to the analysis, each kilogram of dry tea raw materials nitrogen content of 5 to 6 pounds, while the nitrogen absorption rate of about 50%, the production of per kilogram of dry tea required nitrogen 10 to 12 pounds, roughly a pound of pure nitrogen production 10 pounds of dry tea. However, the tea tree to maintain life activities, but also the long tree branches and pruning consumption, in fact, usually a pound of pure nitrogen can only harvest about 7 pounds of dry tea (of course, affected by soil fertility, soil texture and fertilization techniques, etc. Therefore, Annual use of nitrogen per mu, dry tea per mu
