摘　　要：采用连续2年试验示范的方式,研究了茶宝保牌茶树专用肥对幼龄茶树生长发育及土壤的影响。结果表明,3个专用肥处理与常规硫酸钾型复合肥+尿素处理相比,茶苗萌芽时间、发芽时间、一芽一叶初展及一芽二叶初展时间均分别提早2~3 d;第一年茶苗存活率分别提高19.37%、20.48%、21.22%,第二年茶苗存活率分别提高23.72%、25.28%、26.61%;第一年茶苗分枝数量分别增加16.63%、24.71%、30.48%,第二年茶苗分枝数量分别增加17.17%、23.23%、26.57%;对茶苗株高和茎粗的增加作用明显;同时能够提高土壤有机质含量及碱解氮含量,增加土壤肥力,改良土壤。The effects of Chabaobao special tea tree fertilizer on growth and development of young tea plants and soil were studied in two consecutive years.The results showed that,compared with the conventional potassium sulfate compound fertilizer and urea treatment,the germination time,germination time,first bud first leaf spread and first bud two leaf initial spreading time of the three different quantities of tea tree special fertilizer treatment were 2~3 days early,and the survival rate of the first year tea seedlings increased by 19.37%,20.48%and 21.22%,respectively.The survival rate of the second year tea seedlings increased by 23.72%,25.28%and 26.61%,and the number of branches increased by 16.63%,24.71%and 30.48%in the first year respectively.The number of branches of the tea seedlings increased by 17.17%,23.23%,26.57%respectively.The height andthe stem diameter of the tea seedlings increased obviously,and the content of soil organic matter and alkali nitrogen could be increased,soil fertilizer and soil were improved.
