摘要: 研究了农田土壤枯枝落叶分解代谢过程的影响因素。结果表明,农田土壤枯枝落叶分解速率有明显的季节变化;分解速率的高峰值主要是在7,8月份。通过灰色关联分析表明,影响土壤枯枝落叶分解速率的主要因素是弹尾类动物、线虫类动物、无机磷转化作用和土壤含水量。建立了灰色数学模型.

Abstract: Litter decomposition is mainly from July to August in the frigid region of northeast China.The relationship between seasonal variation of soil litter decomposition and 20 ecological factors were studied by grey relation analysis.The primary and secondary factors influencing the decomposition of litter were founded as collembola,nematode,inorganic Ptransformation and moisture.Then the grey models were developed.
