摘　　要：采用大田小区试验,以常规施肥为对照,研究不同控释肥处理对茶园土壤中碱解氮和有机质含量的影响。结果表明:施用活化腐植酸缓释肥、缓释复合肥、生物有机缓控释肥均能显著提高茶园土壤中碱解氮和有机质含量,提高茶园土壤肥力,改善土壤环境,其中以生物有机缓控释肥效果最好。The plot experiment was conducted in field to study the impacts of different controlled - re- lease fertilizers on the available nitrogen and organic matter contents in tea garden soil with conventional fertili- zation as control. The results showed that the application of slow - release fertilizer with activated humic acid, sulfur- coated controlled- release fertilizer, bio- organic slow- release fertilizer could significantly increase the contents of available nitrogen in tea garden soil, so the soil fertility was increased and the soil environment was improved. The effect of bio - organic slow - release fertilizer was the best.
