| 摘 要： | 1年的田间试验表明，施用N,P，K，NP，NK，PK，NPK肥对茶因土壤的速效氮、磷、钾含量影响不大，而施用含硫肥料能明显提高土壤的速效硫含量，比未施含硫肥料的CK(对照)和N处理分别增加31.73％，31.88％；在施肥和不施肥条件下，茶叶中的矿质养分含量基本相似，均是N>K>P>S；大多数施肥处理对茶叶产量的影响不大，但氮肥与磷、钾肥配合施用能提高茶叶产量和产值，并能改善品质。

| Abstract: | In a one-year field experiment,application of N,P,K,NP,NK,PK or NPK had little effect on the available N,P and K in the soil of the tea garden,while S-containing fertilizer markedly increased the content of available S in the soil.Whether fertilizer was applied or not,mineral nutrients in the tea leaves remained similar,which appeared in the order of N(2.80%)>K(2.21%)>P(0.68%)>S(0.38%).The majority of the fertilization treatments hardly affected the yield of the tea,but N applied in combination with P and K enhanced the yield and output value of tea and improved its quality. |
