贵州茶园土壤现状分析与对策

Analysis of the soil present condition and countermeasure of tea gardens in Guizhou

对贵州省茶园土壤的现状和存在问题的调查结果表明,低产茶园面积大,耕作粗放,施肥水平低是影响贵州茶叶产量和品质的主要原因。深耕、增施有机肥料以逐步改良土壤;氮、磷、钾肥配合、平衡施肥;茶行铺草、坡地种植物篱以保蓄土壤水分等是建立高产茶园的主要措施。

In order to improve the yield and quality of tea production in Guizhou province, an investigation on the soil present condition and its problems was conducted.The result indicated that the large area of low-yield tea gardens , extensive cultivation and low-lovel fertilization were the main causes, which resulted in low yield and quality of tea production. To promote the development of tea production, it is necessary to ameliorate soil gradually and build high-yield tea gardens by deep ploughing and increasing the application of organic fertilizer.In the same time it is needed to apply N, P and K fertilizer in a proper proportion i.e. balanced fertilization, and to conserve soil water by spreading straws along tea lines and planting hedgerows on sloping lands.
