摘要
在大叶栎容器苗的育苗期进行了氮、磷、钾3种元素不同配比的施肥试验,研究不同施肥配比处理对其苗木生长量、叶面积、叶绿素含量、生物量以及苗木质量指数的影响。结果表明:不同配比施肥处理的大叶栎容器苗苗木各项指标均存在显著性差异。氮、磷、钾3种元素的平衡施用对大叶栎容器苗生长的促进作用最大,为最优施肥配比,经过4次施肥后苗木的苗高、地径、叶面积、叶绿素含量、地上干重、地下干重分别是不施肥(对照)的205.2%、122.7%、375.3%、148.3%、240.7%、124.7%。
Experiments of formulated fertilization were conducted on container seedlings of Castanopsis fissa,with the objectives of explore the effects of fertilization on growth,leaf area,chlorophyll content and biomass.The experimental results showed that fertilization produced significant effects on growth of container seedlings.The balancing application of N,P and K produced the biggest promotion action on the growth of C.fissa seedling.After 4 times of fertilizing treatments,the height,basal diameter,leaf area,chlorophyll content,above ground dry weight and below ground dry height were respectively 205.2 %,122.7 %,375.3 %,148.3 %,240.7 % and 124.7 % of the control.
