摘要
不同杉木人工林叶片营养与土壤中N、P、K营养元素的回归分析结果表明,各林龄中,叶片N、P含量与土壤N、P含量的回归皆存在极显著正相关,叶片中K与土壤中的K含量不存在显著相关。
The regression analysis results of the blade nutritional elements of different plantations of Cunninghamia lanceolata and the N,P and K nutritional elements in the soil show that the regression of the N and P content in the blades with different forest ages and the N and P content in the soil assumes extremely significant positive correlation whereas the correlation between the K content in the blades and the K content in the soil is not significant.
