腐殖化系数

根据玉米秸科的矿化率以及腐殖化系数，通过Jenny模型可预测秸秆还田后土壤有机质的动态及平衡。

Mineralization rate and humification coefficient of the maize stalks by Jenny model can predict the dynamic and balance of soil organic matter after stalk returned .

干旱地区有机肥料腐解及腐殖化系数的研究

Study on decomposition and humification coefficient of organic fertilizer in arid region

用锦纶袋法测定小麦秸秆在潮土中的腐殖化系数为12.25%。

The humification cofficient of the wheat straw determined with the nylon bag method was 12.25 % .

有机肥料的腐殖化系数在18%～27%，平均215%；

Humification coefficient of organic fertilization is between 18 % and 27 % , with a mean value of 21.5 % ;

各区间的腐殖化系数并不随气候而呈规律性变异，而主要是环境因子综合作用的结果，特别是土壤性质有显著影响。

Humification coefficient did not changed proportionately with temperature and rainfall and was multiply influenced by environmental factors , especially soil properties .

用近似法计量施用有机肥培肥土壤，测定土壤有机质矿化率和农肥及作物根茬的腐殖化系数。

The approximate calculation was applied to determine the application of organic fertilizer and to test organic matter mineralization rate in rice soil and decomposition and humification coefficient of crop stubble .

膨润土能够降低有机物料的分解速率、提高腐殖化系数，从而增加有机质的含量和质量，提高土壤酶活性，改善土壤肥力状况。

It can decrease the decomposition rate of organic substance and improve humification coefficient , so it can raise the quantity and quality of organic matter and improve the sandy soil fertility .

有机质的腐殖化系数：马粪为35%～40%；猪粪为28%～34%；

The decomposition and humification coefficient of organic matter is 35 to 40 percent in horse manure , 28 to 34 percent in swine manure , and 45 percent in rice stubble .

表明土壤有机质矿化率较高，而有机肥料的腐殖化系数较低，这是新疆农田土壤有机质含量难于提高的两个很重要的原因。

It shows that mineralization rate of organic matter is high and humification coefficient of organic fertilization is low , as two important reasons to raise the content of organic matter difficulty in soil .

本文探讨了苕子、柽麻、稻草和锯木屑四种植物残体，在南宁地区赤红土中的腐殖化系数和土壤有机质的自然增减率。

The humification coefficients of plant residues of common vetch , sunnhemp , rice straw and sawdust in lateritic red loam in Nanning prefecture , and the natural increase and decrease rates of soil organic matter were investigated .
