| 摘 要： | 本文报道了施肥４年对杨树人工林土壤养分的消长、水分物理特性及土壤微生物的影响。结果表明，施肥可提高土壤有机质，全Ｎ、速效Ｎ含量，其最适处理（１００ｋｇＮ／ｈｍ２＋１００ｋｇＰ２Ｏ５／ｈｍ２）分别比施肥前提高２１％、６０％和１４％；而施肥对全Ｐ、速效Ｐ以及土壤水分物理特性影响不大；对各处理土壤微生物的分析表明，施肥使土壤微生物总数比造林前提高了３７７％，从而提高土壤活性，促进林木生长。适当地施肥并不会对土壤理化性质和生态环境造成剧烈的影响。

| Abstract: | This paper deal with the effect of fertilization for 4 years on the changes of the soil nutrients, the soil water physical characters and the soil microbes in the poplar plantation. The result showed that in the best treatment(100kg N/hm 2 100kg P 2O 5/hm 2)of fertilization the content of organic matter, total N, rapidly available N in the soil, was increased by 21%, 60% and 14% respectively compared with control. But there was little effect on the total P, rapidly available P and physical water characters in the forest land. The analysis of soil microbes showed that fertilization could increase 37 7% of the total amount of the soil microbes than that before plantation, thus strengthen the activities of soil biochemistry, and promote the forest grew up better. The severe influence on the physical chemical properties of soil and the ecological environment can not result from a suitable fertilization. |
