不同施肥处理对茶苗移栽成活率及生长势的影响

Effects of Different Fertilization Treatments on Transplanting Survival Rate and Growth Vigor of Tea Seedlings

为研究不同肥料对茶苗移栽生长的影响,施入不同浓度的茶叶专用有机肥、茶叶专用有机无机复混肥、茶叶专用复合肥,测定不同施肥处理下茶苗成活率、生长势和叶绿素值等的变化。结果表明:施用茶叶专用有机无机复混肥1500 kg/hm^(2)(B1)和施用茶叶专用有机肥4500 kg/hm^(2)(C3)茶苗移栽成活率均高于对照(CK),并能显著提高苗高、茎粗、叶绿素值和生长势,可在生产中应用推广。

In order to study the influence of different fertilizers on transplanting growth of tea seedlings,the survival rate,growth potential,and chlorophyll of tea seedlings were determined under different fertilization treatments,including different concentrations of special organic fertilizer for tea(C treatment),special organic-inorganic compound fertilizer for tea(B treatment),and special compound fertilizer for tea(A treatment).Results showed that the transplanting survival rates of tea seedlings in B1(1500 kg/hm^(2))and in C3(4500 kg/hm^(2))were all higher than CK,in addition,seedling height,stem thickness,chlorophyll value,and growth vigor were significantly increased,so these two kinds of fertilizers could be applied and promoted in production.
