摘 要: | 通过对长白落叶松S1-1苗木的正交施肥试验,建立了苗高与N肥,新梢与N肥,新梢干重与N、P和全苗干重与N、P的施肥效应函数模型。通过该模型可以计算出不同施肥量下的长白落叶松苗木生物量。最后确定长白落叶松S1-1苗木的最适的施肥量:N为0.16~0.22g/株,P为0.01~0.04g/株。

FUNCTIONAL MODEL OF FERTILIZING EFFECT ON LARIX OLGENSIS SEEDLINGS |
| |
Abstract: | In this paper was set up the functional model of fertilizing effect between seedling height and N,new tip and N,tip dry weight and N/P,and whole seedling dry weight and N/P.According to the model was calculated seedling growth under different applying quantities.Finally was determined the optimum fertilizing quantity of larix olgensis:0.16~0.22 g per plant for N;0.04~0.01 g per plant for P. |
