| 摘 要： | 通过在土壤中埋置砂滤管的方法明确不同积温、水分、pH以及物料与黑土不同配比条件下有机物料的分解情况。结果表明：小麦和草木樨秸秆在低温下也易于分解，但不利于土壤有机质的积累，而玉米和大豆残体，在高温条件下易于分解，低温有利于土壤有机物的积累；在灌溉的条件下，小麦和草木樨秸秆易于分解；而玉米和大豆残体，在灌溉条件下易于碳的积累；不同量有机物料与土壤混合发现，加入秸秆量越少，分解越少；土壤pH在作物残体还田的第一年影响其分解速度，加速积累不易于分解，以后影响不明显。

| Abstract: | The method of sand strainer tube was used in this trial for studying the decomposing regularity of organic materials on the condition of different accumulated temperature, moisture, pH, materials and soil proportion. The result shows that： wheat and sweet clover straw were prone to decompose at low temperature, decomposition rate was sweet clover higher than wheat straw. In water condition, sweet clover and wheat straw were prone to decompose in the first year were 20% higher than normal, average decomposition rate was only 10% in the second year. The fastest decomposition, the least addition. When adding amount of 1% straw, the decomposition rate is 75.6% in first year, and the second year up to 88.8%. Wheat straw decomposition rate is 63.1% at pH 7 and 75.6% in pH 8.7, the remaining also have a difference of about 10%. Pipes next year, decomposition rate of various materials were stabilized. Therefore, soil organic matter decomposition not only because of the type of organic materials there are differences, but also by some properties of the soil （such as moisture, pH） and climate （such as temperature） as well as to field the quantity of factors. |
