茶园土壤是茶树的生长基地,土壤肥力的高低,直接影响着茶树的生长发育和茶叶的产量质量。新垦茶园由于红黄壤的土质酸瘦粘重板结,有机质缺乏,合氮量低,缺磷少钾,极不利于幼龄茶树的成长。因此利用幼龄茶园,树冠覆盖度低,行间土地空旷时期,进行绿肥间作用以压青,可以增加土壤中的有机质和氮、磷、钾肥分;由于有机物质的积累,能改善土壤的团粒结构,使土质疏松,增强渗透性,提高土壤的透气、吸水蓄水和 Tea plantation soil is the growth base of tea tree, soil fertility level, directly affects the tea tree growth and yield and quality of tea production. New Ken tea garden soil due to red and yellow soil slender sticky compaction, lack of organic matter, combined nitrogen is low, lack of phosphorus and potassium, is very detrimental to the growth of young tea trees. Therefore, the use of young tea plantations, canopy cover is low, the open space between the rows of land, green manure to pressure green, can increase the soil organic matter and nitrogen, phosphorus and potassium fertilizer; organic matter accumulation can improve soil aggregate Structure, loose soil, enhance permeability, improve soil breathability, water absorption and storage
