摘　　要：文章采用田间试验研究了沼液、化肥和商品有机肥不同处理对春茶产量和品质的影响。试验结果表明,与施用化肥、商品有机肥相比,施用沼液可提前春茶萌动时间,分别提前3～4 d和6～7 d;沼液施用可以增加春茶发芽密度,当沼液施用量为4500 kg·666.67m^(-2)时效果最佳,与化肥、商品有机肥相比,分别提高19.8%,17.40%;在春茶产量方面,首轮采摘沼液处理均高于化肥、商品有机肥处理,总产量上,施用量为5500 kg·666.67m^(-2)时,春茶产量、产值达最优,分别为53.50 kg·666.67m^(-2),4353.41元·666.67m^(-2)。田间试验证实,施用沼液能改善茶叶品质,提高水浸出物、游离氨基酸含量,降低咖啡碱、茶多酚和酚氨比。The effects of different fertilizer(biogas slurry,chemical fertilizer,and commercial organic fertilizer)on the yield and quality of spring tea were studied adopting field experiment.The experimental result showed that the biogas slurry from pig farm could make the spring tea sprouting 3~4 days or 6~7 days ahead of time comparing with the chemical fertilizer and the commercial organic fertilizer respedively.Also,the biogas slurry could increase the budding density,which were 19.8%and 17.40%higher than the chemical fertilizer and the commercial organic fertilizer respectively when slurry dosage of 4500 kg·666.67m^-2 were used,In terms of the output of the spring tea,the tea treated with the biogas slurry had higher output than that of the chemical fertilizer and the commercial organic fertilizer during the first pick up.In terms of total output,slurry dosage of 5,500 kg·666.67m^-2 obtained the best spring tea output,the yield was 53.50 kg·666.67m^-2,and the value was 4353.41 yuan·666.67m^-2.
