摘    要:通过盆栽和野外山场试验,对杉木幼林(苗)施磷肥进行了研究,应用向量图解分析法对其微量元素状况作了诊断。结果表明:施肥后2a内磷肥的利用率福建山场试验高于江苏下蜀黄土的盆栽试验,各施肥处理以磷酸铵最高;施用常规肥料对土壤微量元素供应也有一定作用,盆栽杉苗施用单一磷肥增加了苗木对有效铁和氮素的吸收,氮、磷肥共同施用(磷酸铵)增加了杉苗对钼的吸收,这表明磷的缺乏可能会诱导杉苗有效铁和氮素的不足,氮素的缺乏可能会诱导钼的亏缺。

关 键 词:杉木  施磷肥  肥料利用率  微量元素  向量图解分析

Abstract:The P fertilization tests, including pot experiments in Jiangsu province and outside experiments in Fujian province, were studied in young Chinese fir plantation. The results revealed that the P utilization percentage of Chinese fir stands in Fujian is much higher than that of the pot experiment in Jiangsu. The highest P utilization percentage is ammonium phosphate, which were 4.06% and 10.04% in pot and outside experiment respectively. In pot experiment, P fertilization increased Fe and N absorption, N and P associate fertilization increased Mo absorption, P shortage may induce Fe and N shortage, N shortage may induce Mo shortage.
Keywords:Chinese fir  P fertilization  Fertilizer utilization percentage  Microelements  Vector analysis
