摘 要：以茶树品种槠叶齐为材料，研究茶叶专用套餐肥对茶叶产量与品质的影响。结果表明：与对照相比，施用茶叶专用套餐肥的t1～t4处理春茶发芽密度分别提高了18.48%、16.96%、13.34%、28.77%，夏茶发芽密度分别提高了2.99%、0.48%、0.12%、7.31%，春茶鲜叶产量分别提高了22.89%、5.65%、27.34%、11.60%;t1、t4处理的春茶水浸出物含量分别提高0.08%、5.84%;茶多酚含量分别提高2.18%、7.80%;氨基酸含量分别提高5.45%、6.68%。这表明该茶叶专用套餐肥可在一定程度上促进茶树生长，提高茶叶产量与品质，尤以t4处理[基肥，茶叶专用复合肥（n-p2o5-k2o=24-11-10）80 kg/667m2;追肥包膜尿素（44%）10kg/667m2]效果更佳。

abstract： using the tea variety zhuyeqi as the experiment material， the effect of tea special set fertilizer on tea yield and quality was studied. the results showed that compared with the control， in t1-t4 treatments applied with tea special set fertilizer， the germination density of spring tea increased by 18.48%， 16.96%， 13.34% and 28.77%， respectively， that of summer tea increased by 2.99%， 0.48%， 0.12% and 7.31%， respectively， and the fresh leaf yield of spring tea increased by 22.89%， 5.65%， 27.34% and 11.60%， respectively. in t1 and t4 treatments， the content of water extract of spring tea increased by 0.08% and 5.84%， respectively， the content of tea polyphenols increased by 2.18% and 7.80%， respectively， the content of amino acids increased by 5.45% and 6.68% respectively. the tea special set fertilizer can promote the growth of tea plants and improve tea yield and quality to a certain extent， especially t4 treatment [tea special compound fertilizer （n-p2o5-k2o=24-11-10） 1 200 kg/hm2; top dressing with coated urea （44%） 150 kg/hm2] has a better effect.
