通过田间小区试验，研究不同土壤调理剂对土壤理化性质和茶叶品质的影响。结果表明，施入土壤调理剂的处理土壤容重均降低，孔隙度均增加，腐殖酸和风化煤处理土壤容重分别比化肥处理降低12.5%和5.7%，腐殖酸+风化煤处理土壤容重低于腐殖酸处理高于风化煤处理。茶叶中氮、磷、钾矿质养分含量以腐殖酸处理最高，这与腐殖酸处理土壤中速效氮、磷、钾含量较高有关。茶青产量增加，以腐殖酸的效果较好，增产11.5%；腐殖酸处理茶叶中茶多酚和水浸出物含量都高于其他处理，分别比化肥处理提高20.8%和9.4%。可见，土壤调理剂的施入既能改善土壤结构，对植物生长提供良好的土壤环境，又能增加茶青产量，提高茶叶品质。

The effects of soil conditioners on soil physical and chemical properties of tea garden and tea quality were studied through field experiments. The results showed that the bulk density decreased and the specific weight of soil and porosity increased after applying soil conditioners. Soil bulk density of humic acid and weathered coal treatments were decreased by 12.5% and 5.7%, respectively compared with the fertilizer treatment. Soil bulk density of humic acid and weathered coal co-application treatment varied between them. The contents of nitrogen, phosphorus and potassium in tea of humic acid treatment were all higher than those of other treatments due to the high contents of available nitrogen, phosphorus and potassium in soil treated by humic acid. Humic acid treatment had the highest yield with increase of 11.5%. Tea polyphenols and water extractive contents of humic acid treatment were higher than those of other treatments with increase of 20.8% and 9.4%, respectively compared with chemical fertilizer treatment. Soil conditioners can improve soil structure, provide good soil environment for plant growth, and increase the yield of improve the quality of tea.
