Abstract: In this study,the humus composition analysis under different straw returning the fertilization treatment on noncalcareous fluvo aquic soil humus content and structure change,in order to improve topsoil fertility and reasonable utilization of agricultural waste straw provides a good basis for amending method and infrared spectroscopy.Based on the long-term field experiment,five treatments were set up,and two treatments were applied to the treatment of wheat,corn straw returning (WCN),wheat straw returning to field (WN),and two season (WC),control (CK) and (M).Research results showed that:under the condition of returning straw to field with time.The content of Humic acid (HA) and Fulcic acid (FA) in each soil was increased by 117.68% and 102.5% respectively compared with 2009.Compared with CK,the total content of soil Humic acid (HA) increased by 21.8%-47.9%,the highest content of humus was WCN,in 2015,compared with CK growth of 118.8%,compared with 2009,the original soil increased by 183.63%.Two season straw returning to the field with chemical fertilizer treatment,can increase the soil humic acid and rich in acid content,the ratio of Hu rich increase,increase the humic acid content and make it stable growth.Soil humus activity from high to low was:WCN > WN > M > WC.Two seasons of straw and with application organic fertilizer,improve the aromatic and carboxyl compounds content,and polysaccharide compounds decreases,enhance soil humus activity and aromatization degree.The two quarter straw fertilizer nitrogen could increase the content of organic carbon in soil,improve soil fertility.

Key words: Infrared spectrometry, Straw returning, Humus content, Humus structure
