1985～1987年间对湖南省具有代表性的茶园土壤进行了调查研究。结果表明,大多数茶园土壤的养分含量属于中下水平,7项农化指标含量变异都较大。土壤全氮与茶叶氨基酸或咖啡碱的含量呈显著正相关;土壤Al—P是茶树磷营养的有效给源;土壤有效锌与茶叶氨基酸含量呈显著正相关;施铝肥显著地提高了茶叶中萘氨酸的含量,施硼肥则明显提高茶芽重量,施锰肥对茶叶中茶氨酸,天门冬氨酸含量有显著提高作用。旺产期茶园每亩年输出N7.7公斤,P0.43公斤,K3.4公斤,Ca1.2公斤,Mg0.78公斤,Mn0.6公斤,Zn12.9克。生产百公斤茶叶需N、P、K、Ca、Mg、Mn分别为96.2、28.5、41.8、18.0、27.8和5.80公斤。本文还提出了茶园土壤养分的调控措施。
From 1985 to 1987, the representative tea plantation soils in Hunan Province were investigated. The results showed that most of the tea plantation soil nutrient content belongs to the middle and lower levels, seven agrochemical indicators of variation are larger. Soil total nitrogen and tea leaf amino acid or caffeine content was significantly positive correlation; soil Al-P is an effective source of phosphorus nutrition in tea plantation; soil available zinc and tea amino acid content was significantly positively correlated; application of aluminum fertilizer significantly increased the naphthalene in the naphthalene The contents of the acid and the boron fertilizers obviously increased the weight of the tea buds, and the manganese fertilizer significantly increased the contents of theanine and aspartic acid in tea. High yield per acre tea output N7.7 kg, P0.43 kg, K3.4 kg, Ca1.2 kg, Mg0.78 kg, Mn0.6 kg, Zn12.9 grams. Production of 100 kilograms of tea required N, P, K, Ca, Mg, Mn were 96.2,28.5,41.8,18.0,27.8 and 5.80 kg. The paper also proposed the regulation of soil nutrients in tea plantation.
