| 摘 要： | 对云南屏边6、13及18年生杉木人工林林地土壤理化性质的调查分析结果表明种植杉木后,林地土壤含水量增加,容重降低,紧实度减小,土壤物理性状有改善的趋势;土壤有机质逐渐增加,速效P、pH逐渐降低,而水解N在杉木生长后期有上升趋势,速效K则变化规律不明显.

| Abstract: | Soil study on Cunninghamia lanceolata plantations of 6,13 and 18 years old in Pingbian county of Yunnan province were conducted to learn the effect of C lanceolata plantation on soil physical and chemical properties.The results were:after C lanceolata plantation,the moisture content increased,bulk density decreased,compactness decreased,physical and chemical characters were improved,the content of organic matter increased,the content of rapidly available phosphorus and soil pH value decreased,the content of hydrolysable nitrogen showed the tendency of increase at the later period of growth,the change of rapidly available potassium was not obvious. |
