黑龙江省农科院迟凤琴通过对常见的五种有机物料在风沙土中的腐解规律研究结果表明，各种物料在风沙土中对土壤有机质积累的贡献大小依次为草炭＞厩肥＞小麦秸秆＞玉米秸秆＞草木樨秸秆。根据有机物料在土壤中腐解参数，用Ｊｅｎｎｙ模型，可以算出每年需施草炭（干重）４．４
The results of the study on the decomposition regularity of five common organic materials in aeolian sandy soil showed that the contribution of various materials to the accumulation of soil organic matter in aeolian sandy soil were in the order of peat> manure> wheat straw > Corn stalks> grass stalk straw. According to the decomposing parameters of organic materials in soil, using Jenny model, it can be calculated that the application of peat (dry weight) 4.4
