Non-pollution tea tree management technology
Tea garden soil should be tilled frequently to facilitate microbial activities, accelerate soil maturation, promote the release of mineral elements, and facilitate root absorption. Depending on the soil structure, shallow tillage is carried out several times a year at a depth of 5~10 cm; intertillage is carried out 2~3 times at a depth of 10~15 cm; deep tillage is carried out once a year or every other year at a depth of 25~30 cm. Shallow tillage and intertillage can be combined with weeding and topdressing in each tea season, while deep ploughing can be combined with clearing garden or applying organic fertilizer.
