摘要：杉木［Ｃｕｎｎｉｎｇｈａｍｉａｌａｎｃｅｏｌａｔａ（Ｌａｍｂ．）Ｈｏｏｋ．］人工林土壤立地大多供Ｐ不足，杉木幼林施用磷肥肥效显著。李贻铨等认为施Ｐ、Ｋ肥能促进杉木幼林生长［１，２］；叶仲节认为幼林施Ｐ肥初期有效，施Ｎ无效，施Ｋ还会出现负效应［３］。作...
The effects of applying P fertilizer on nutrition and P fraction in yellow red soil of young Chinese fir plantation were studied in Jiangxi Province in 1991～1994. Fertilization increased the contents of organic matter,total N and P,available N and P,Fe P and O P in soil. Compared with the control,the contents of organic matter,total N and available N were increased by 43%,27% and 32% in treatment 5 (N 100 P 100 /ha) and 6 (N 100 P 100 K 100 /ha),total P and available P were increased by 70% and 356% in treatment 5,respectively. The increased Fe P (except for treatment 1) and O P (except for treatment 3) ranged 2.5～13.9 mg/kg and 6～73 mg/kg,respectively. Ca P in soil was reduced by 0.3～9.0 mg/kg in fertilized plots. There were different changes in organic P in various fertlized plots. Organic P was reduced by 87～128 mg/kg in treatment 2,5 and 6 while it was increased by 21～97 mg/kg in treatment 1,3 and 4. Compared with the control,there was no significance in the effects of fertilization on pH value and Al P in soils.
