Abstract：
Lushan Yunwu tea quality is limited by soil acidity and sterility. This article examined a 3-year localization experiment at 1100 m altitude to demonstrate the sustainable management of conditioners, calcium magnesium phosphate (P), rapeseed cake (C), and combination application (P + C) by one-time application on the soil-tea system in Mount Lushan. The study found that conditioners (P, C, P + C) reduced soil acidification and maintained a pH of 4.75-5.34, ideal for tea tree development for 3 years. Phosphorus activation coefficient (PAC), nitrogen activation coefficient (NAC), and organic matter (OM) content were significantly higher (P < 0.05) in the first year after conditioner treatment, with P + C being the best. After P + C, PAC, NAC, and OM rose by 31.25%, 47.70%, and 10.06 g kg-1 compared to CK. In comparison to the CK, tea\'s hundred-bud weight (BW), free amino acids (AA), tea polyphenols (TPC), and chlorophyll (Chl) content of P + C treatment got 29.98%, 14.41%, 22.49%, and 28.85% increase compared to that of the CK, respectively. In the second year, the three treatments of P, C and P + C still had significant moderating effects on the physicochemical properties of the soil and the quality indexes of the tea leaves. The PAC of the soil under the three treatments increased by 0.06%, 0.07% and 0.18%, respectively, as compared to the control.P + C increased BW, AA, TPC and Chl of tea for 2 years. Three conditioners had 2-year regulatory impacts on soil fertility indicators, tea output, and quality. C and P + C both increased soil OM by 18.59% and 21.78% compared to CK in the third year, outperforming P treatment. Redundancy analysis revealed that the primary physicochemical factors influencing tea output and quality were soil OM and pH, with available phosphorus, urease, acid phosphatase, and available nitrogen following closely afterwards.
摘要：
庐山云雾茶品质受到土壤酸度和不育性的限制。本文研究了在1100m海拔的3年定位实验，以证明调理剂的可持续管理，磷酸钙镁（P），油菜籽饼（C），在庐山的土壤-茶叶系统上一次性施用和组合施用（PC）。研究发现，调理剂(P，C,PC）减少了土壤酸化，并保持了4.75-5.34的pH值，非常适合茶树发育3年。磷活化系数(PAC),氮活化系数(NAC)，和有机质(OM)含量显著高于调理剂治疗后的第一年(P<0.05),P+C是最好的。P+C之后,PAC,NAC,OM上升31.25%，47.70%,与CK相比，为10.06gkg-1。与CK相比,茶的百芽重量（BW），游离氨基酸(AA),茶多酚（TPC），P+C处理的叶绿素(Chl)含量达到29.98%,14.41%,22.49%,与CK相比增加了28.85%，分别。第二年,P的三种处理，C和P+C对土壤理化性质和茶叶品质指标仍有显著的调节作用。三种处理下土壤的PAC增加了0.06%,0.07%和0.18%，分别,与对照组相比。P+C增加BW,AA,茶的TPC和Chl为2年。三种调理剂对土壤肥力指标有2年的调控影响，茶叶产量，和质量。第三年C和P+C均使土壤OM比CK增加18.59%和21.78%,优于P治疗。冗余分析表明,影响茶叶产量和品质的主要理化因子是土壤OM和pH,有效的磷，脲酶,酸性磷酸酶,和可用氮紧随其后。
