Abstract

Abstract: In order to study the effects of different straw returning on soil organic carbon and humus content,we have regard Laiyang long-term straw returning to the soil in aquic soil treatment as the research object of study,explore the effect of application nitrogen fertilizer or organic fertilizer in straw returning to field on soil organic carbon(SOC) and humus content.The results were as follows:In the 5 experiment treatments,the WCN treatment's organic carbon and humic substances were the maximum,was the optimal treatment.The main effect from the maximum to minimum values were:nitrogen fertilizer,organic fertilizer,straw returning+nitrogen fertilizer and straw returned to the soil.Compared with CK,straw with nitrogen fertilizer applicating to the soil substantial increased HA,HM,FA contents and made it in a stable level.Compared with the single application of organic fertilizer,WN,WCN treatment could significantly increase the content of soil humus fractions.As time goes by,straw and nitrogen fertilizer(WN,WCN) could significantly increase the content of soil humus fractions.

Key words: Straw returning, Organic carbon, Humus
