毛竹林带采伐宽度对土壤碳氮磷含量及计量比的影响
Effects of soil nutrients on C,N,P and stoichiometry of Phyllostachys edulis forests under different strip clear cutting.
毛竹带状采伐是近年来为了适应机械化作业而提出的新理念,探讨带状采伐宽度对土壤养分含量及计量比的影响,对选择合理的采伐带宽,支撑毛竹林采伐模式的更新具有重要的作用意义。本研究设置 4种采伐带宽(3 m、6 m、9 m、12 m)的试验样地,以传统择伐毛竹林为对照(CK),比较不同处理土壤C、N、P含量及比值的差异性。结果表明:随着采伐宽度的增加,土壤C、N、P呈先增加后降低的趋势,采伐带宽 6 m时含量最高,12 m时含量最低;土壤C/P、N/P随…查看全部>>
In order to scientifically manage the strip clear cutting of moso bamboo forests,we studied the effects of different cutting widths(3 m,6 m,9 m,12 m)on the soil characteristics of moso bamboo forests after strip clear cutting.The results showed that with the increase of cutting width,the content of soil C,N and P increased at first and then decreased.The content of soil C,N and P was the highest at 6 m and the lowest at 12 m;Soil C/P and N/P increased first …查看全部>>
