摘　　要：为明确化肥减施对春茶产量和品质的影响,设置100%化肥处理(当地传统施肥量)A,100%有机肥处理B和30%有机肥+70%化肥处理C,以及空白对照4种施肥处理。结果表明,所有施肥处理产量、百芽重和发芽密度均高于对照,但不同处理间差异不显著;化肥减施处理C茶多酚、氨基酸含量和酚氨比相对其他施肥处理差异不显著,水浸出物含量低于其他处理。化肥减施处理C春茶儿茶素(C)含量明显降低,同其他施肥处理春茶的C、GCG、和CG含量差异明显。施肥可以提高春茶叶绿素a和类胡萝卜素含量,降低叶绿素b含量,但化肥减施处理叶绿素组分含量与其他处理没有显著差异。In order to clarify the effects of fertilizer reduction on the yield and quality of spring tea,four fertilization treatments,including 100%fertilizer(local traditional fertilizer amount)A,100%organic fertilizer B,30%organic fertilizer+70%fertilizer C and blank control CK were set.The results showed that the yield,hundred-bud weight and germination density of all fertilization treatments were higher than that blank control,but the differences between different treatments were not significant.The contents of tea polyphenols,amino acids and the ratio of phenol to ammonia in chemical fertilizer reducation treatment were not significantly different from those of other fertilization treatments,and the content of water extract was lower than that of other treatments.The content of catechin(C)in spring tea under fertilizer reduction treatment was significantly reduced,and the contents of C,GCG and CG were different from that under fertilizer treatment.Fertilization could increase the content of chlorophyll a and carotenoid and decrease the content of chlorophyll b,but there was no significant difference between fertilizer treatments.
