不同抚育方式对毛竹林土壤化学性质的影响

对毛竹林分别采用不同的抚育措施,测定土壤有机质、全氮、水解氮、速效磷和速效钾含量、土壤pH值等指标,研究毛竹不同抚育方式的土壤化学性质。结果表明：以劈草抚育方式最好,化学锄草次之,深翻抚育最差。在毛竹林的抚育方式上应大力推广劈草抚育,谨慎采用化学除草和浅锄抚育,杜绝深翻抚育。

A Study of Soil Chemical Nature under Different Bamboo Forest Tending Methods

From October 1996 to October 2008, moso forest was tended by weeding, chemical weeding, shallow hoeing and deep ploughing. The soil chemical nature under different Moso forest tending methods was then studied by means of measuring the indicators such as soil organic matter, total nitrogen, hydrolysable nitrogen, available phosphorus and potassium and soil pH. The results showed that among the four methods, weeding tending was the best, followed by chemical weeding, and deep ploughing tending was the worst, in terms of the measuring of above indicators. So, weeding tending should be greatly popularized. And it should be careful to adopt chemical weeding and shallow hoeing tending, and never apply deep phoughing tending.
