针对茶叶生产中存在化肥施用过量、有机肥施用量不足及养分配比失衡等因素造成的土壤养分流失、茶叶品质下降等问题,开展了连续3年的田间小区试验。试验共设置6个处理,以不施肥为对照(CK)处理,T1~T5处理分别施用茶叶专用复合肥+尿素、有机无机复合肥、茶叶专用有机肥+茶叶专用复合肥+尿素、茶叶专用有机肥+通用型复合肥+尿素、通用型复合肥+尿素,考察了不同处理的茶叶产量、主要品质成分含量和感官品质、土壤理化性状等指标。结果表明,T3处理不仅在提高茶叶产量、保证茶叶品质方面效果显著,还提高了土壤中有机质的含量,具有较好的施肥综合效益。
To address issues in tea production, such as excessive chemical fertilizer application, insufficient organic fertilizer usage, and imbalanced nutrient ratios—leading to soil nutrient loss and declining tea quality—a three-year continuous field plot experiment is conducted. Six treatments are established: no fertilization as the control (CK), while treatments T1 to T5 involve the application of tea-specialized compound fertilizer + urea, organic-inorganic compound fertilizer, tea-specialized organic fertilizer + tea-specialized compound fertilizer + urea, tea-specialized organic fertilizer + conventional compound fertilizer + urea, and conventional compound fertilizer + urea, respectively. Indicators including tea yield, key quality components content, sensory quality, and soil physical and chemical property are evaluated under different fertilization treatments. The results show that T3 treatment not only significantly improves tea yield and preserves quality but also increases soil organic matter content, exhibiting superior comprehensive fertilization benefits.
