【摘要】 对厚荚相思树施用不同水平基肥(800,1 200,1 600,2 000,2 200 g/株),研究树木高生长、胸径生长、叶片营养元素和叶绿素含量的变化,结果表明:基肥水平以 1 600 g/株为最好,厚荚相思的生长指标、叶片营养元素和叶绿素含量均好于其他4种基肥处理水平,而且差异达到显著性水平。更多还原

【Abstract】 Based on the different levels of basal manure(800 g per plant,1 200 g per plant,(1 600 g) per plant,2 000 g per plant,2 200 g per plant),the effects of basal manure on growth,leaf mineral elements and chlorophyll contents in Acacia crassicarpa were studied.The results showed that the 1 600 g per plant treatment was most effective.With this treatment,the growth and leaf mineral elements and chlorophyll contents of A.crassicarpa all increased more greatly compared with the other treatments,and the analysis of variance shows that the differences between this treatment and others were significant.更多还原
