摘  要：
通过设置施氮水平、有机肥与化肥配施比双因素田间试验,研究了不同施肥结构对茶园土壤有机质和氮素营养、春茶产量和品质的影响。结果表明,与不施肥处理相比,各种施肥处理均能有效提高茶园土壤有机质和全氮含量,且均在900 kg·hm-2的施氮水平下75%有机肥+25%化肥处理效果最为显著;施肥可以显著提高春茶芽叶密度、百芽重等产量指标;有机肥比例高于25%的氮素处理能显著提高春茶的品质指标,有机肥比例50%以上时效果更好。

摘  要：
Through field test by setting factors of nitrogen level and organic/chemical fertilizer ratio, we studied the effects of different fertilizer application systems on organic matter and nitrogen nutrition in tea garden soil, as well as tea yield & quality were investigated. The results showed that contents of organic matter and total nitrogen were significantly increased under all various fertilizer treatments, and applying 75% organic manure combined with 25% chemical fertilizers with 900 kg·hm-2 high nitrogen level exhibited the most remarkable increasing effects. Compared with no fertilization treatment, indicators of tea production including the bud-leaf density, 100-bud weight were increased under all various fertilizer treatments. Furthermore, the quality indicators of spring tea were dramatically increased under such fertilizer treatments that organic manure more than 25%, the tea quality improved more while organic manure was more than 50 %.
