摘要

对杉木林刚皆伐和皆伐半年后的土壤剖面的pH值、有机质、水解性氮、速效磷和速效钾含量进行了分析

目的在于为杉木人工林的更新和维护地力的机制提供依据。与刚皆伐各土层的土壤相比

皆伐半年后相应土层的土壤pH值均有所下降

土壤有机质及除土层0-5cm外的速效磷和速效钾含量均有所增加

而水解性氮含量在一些土层增加

在其它土层中下降。

Abstract

The paper dealt with soil nutrients of a Chinese firstand after clear cutting in Yunyong Forest Farm based on the determination of soil pH value

soil organic matter

hydr olyzable nitrogen

available phosphorus

and available potassium in 0) 100 cm layer in October

2004 and April

2005. The study may provide a scientific basis for Chinese firstand reforestation and site productivity maintenance. Compared with all the soil layers in 2004

the pH values of all the soil layers in 2005 decreased; the contents of soil organic matter and available potassium and the contents of soil available phosphorus except for 0) 5 cm increased; and the contents of hydrolyzable nitrogen increased in some soil layers and decreased in other soil layers.
