摘　　要：[目的]明确茶树幼苗期营养液配方技术,以便更好更快地培育出优质茶苗。[方法]分别取尿素50、100、150、200 g,加入已稀释的改良的营养液中,分析不同氮素浓度的营养液与茶树幼苗生长的关系,用0.5%尿素水溶液作对照,3次重复。[结果]100 g N素区处理茶苗长势最好,具体表现为茶苗的平均苗高达32 cm,冠径达23 cm,着叶数达44.4片,根冠比达3.4。[结论]该研究阐明了不同氮素浓度营养液对茶苗质量的重要作用,达到了茶树育苗的预期效果,可为茶树育苗技术及推广应用提供理论基础。[Objective] The aim was to confirm on the nutrition liquid formulation technology of tea tree at seedlings stage, and to bred good quality tea seedlings better and rapidly. [Method] 50, 100, 150,200 g urea were added into diluted and modified nutrition liquid to analyze the relationship between different concentration nitrogen nutrition liquid and tea tree seedlings growth, taking 0.5% urea solution as control with three repeated. [ Result] The 100 g N treatment＇ s tea seedlings growth was the best, the specifie performance of tea seedlings was as follows： the average height was 32 cm, the canopy diameter was 23 cm, the leaf number was 44.4, the root to shoot ratio was 3.4. [ Conclusion] The study illustrates the important role of different nitrogen concentration nutrient solution on the quality of tea tree seedling, and achieves the anticipated effect of tea seedlings, provides the theoretical basis for seedling technology of tea tree and its application and popularization.
