中文摘要：

利用1995年到2006年长期定位各处理土壤有机碳含量及气候因子的资料,分析各气候因子与有各处理土壤有机碳含量的相关性。结果表明：营养生长阶段月平均气温变化对土壤有机碳含量的影响较大,与施用有机肥的处理相关性较强,生殖生长阶段温差越大越利于有机碳的积累;各月降水量对有机碳的影响基本上呈负相关,在苗期和乳熟期降水增多不利于有机碳的积累;日照时数的增加可以提高有机碳的含量,这一作用在生殖生长阶段表现的更为明显。整体来说,不施有机肥处理土壤有机碳含量受气候因子的影响比较明显,尤其是CK处理,而施用有机肥的处理的土壤有机碳含量仅在营养生长阶段受气候因子的影响比较明显。

英文摘要：

Based on the date of soil organic carbon contents of different treatments and climate factors of long- term fertilization from 1995 to 2006, the correlations of each climate factor and organic carbon content of different treatments were analyzed. The results showed that the change of month average temperature during the trophic growth stage had more influence on the soil organic carbon content. It had obvious correlation with the treatment that using organic manure. It＇s better for accumulating of organic carbon if the difference in temperature was larger during the generative growth stage. The correlation of per month precipitation and organic carbon content was basically negative. It＇s disadvantaged for accumulating of organic carbon when increasing precipitation during the seedling stage and milk mature stage. Increasing the sunlight hours could enhance the organic carbon content, and its effect on generative growth stage increased. In general, the influence of climate factors was much obvious on soil organic carbon content of no organic manure treatments, especially the CK treatment. The organic carbon content of using organic manure treatments was only influenced by climate factors during the trophic growth stage.
