中文摘要:

土壤的水池上的长期的授精的效果器官的碳(SOC ) 很好被学习了,但是有限信息在可氧化的器官的碳(OOC ) 上是可得到的部分,特别为在中国的黄土高原。我们在九个处理下面在扁平的农田在 0-20 和 20-40 厘米土壤层在 OOC 部分( F1 , F2 , F3 和 F4 )上评估了15年的授精的效果( N (氮,脲), P (磷, monocalcium 磷酸盐), M (器官的化肥, composted 绵羊粪肥), N+P ( NP ), M+N ( MN ), M+P ( MP ), M+N+P ( MNP ), CK (控制,没有化肥)并且赤裸的土地( BL ,没有庄稼或化肥))。SOC 内容在独自与无机的化肥比在那些包含粪肥的处理更显著地增加了。F1, F2, F4 和 F3 分别地说明了 47% 全部的器官的碳, 27% , 18% 和 8% 。F1 比在敏感索引(SI ) 的另外的 C 部分是一个更敏感的索引分析。F1 和 F2 高度与全部的氮(TN ) 和可得到的氮被相关(一) , F3 否定地与 pH 被相关, F4 与 TN 被相关。簇分析证明包含粪肥的处理形成了一个组,并且另外的处理形成了另一个组,它在土壤性质上显示了授精的不同效果。当时,有无机的化肥的长期的授精增加了 F4 部分粪肥化肥在一短时间的不仅增加的易变的部分(F1 ) ,而且增加的被动部分(F4 ) 在上一长期。混合化肥主要影响了 F3 部分。学习证明粪肥化肥为农业的长期的可持续性在黄土高原上在农田被推荐到使用。

英文摘要:

The effects of long-term fertilization on pools of soil organic carbon (SOC) have been well studied, but limited information is available on the oxidizable organic carbon (OOC) fractions, especially for the Loess Plateau in China. We evaluated the effects of a 15-year fertilization on the OOC fractions (F1, F2, F3 and F4) in the 0-20 and 20-40 cm soil layers in flat farmland under nine treatments (N (nitrogen, urea), P (phosphorus, monocalcium phosphate), M (organic fertilizer, composted sheep manure), N+P (NP), M+N (MN), M+P (MP), M+N+P (MNP), CK (control, no fertilizer) and bare land (BL, no crops or fertilizer)). SOC content increased more markedly in the treatment containing manure than in those with inorganic fertilizers alone. F1, F2, F4 and F3 accounted for 47%, 27%, 18% and 8% of total organic carbon, respectively. F1 was a more sensitive index than the other C fractions in the sensitivity index (SI) analysis. F1 and F2 were highly correlated with total nitrogen (TN) and available nitrogen (AN), F3 was negatively correlated with pH and F4 was correlated with TN. A cluster analysis showed that the treatments containing manure formed one group, and the other treatments formed another group, which indicated the different effects of fertilization on soil properties. Long-term fertilization with inorganic fertilizer increased the F4 fraction while manure fertilizer not only increased labile fractions (F1) in a short time, but also increased passive fraction (F4) over a longer term. The mixed fertilizer mainly affected F3 fraction. The study demonstrated that manure fertilizer was recommended to use in the farmland on the Loess Plateau for the long-term sustainability of agriculture.
