长期定位秸秆还田不同施肥处理对土壤腐殖质组分含量的影响
Effects of Long Term Positioning of Straw Returning to Field of Different Fertilizer Treatments on Content of Soil Humus Fractions
摘要
Abstract
Through 6 years of field experiments,the intention of the experiment was to study the effects of the different fertilizer treatments on the soil humus content changes under the condition of wheat-corn straw returned. The results suggested that humic acid (HA),fulvic acid (FA)and humin (HM)content increased gradually with the increase of age of straw length.Contrast with CK,3 types of straw return to soil humic acid with an average increased of 3.84% to 62.1 6%,there were significant differences among them.The soil humus (HA,FA,HM)con-tent in WCN treatment was the highest,and the averagely increased 98.1 6% than CK.WN,WCN and M treatment could improve the content of soil water soluble substance (WSS),the contents of WSS under WC treatment were sta-ble in (0.29 ±0.1 1 )g /kg level.WCN compared to CK increased by 89.29%.With the increase of straw returning years,the treatment of WCN HA /FA and the PQ value reached maximum in 2014,1 .08 and 0.52 respectively.It stated that two seasons could enhance the content of soil humic acid(HA),humin (HM),fulvic acid (FA)and could also significantly improve humus soil humification degree,increase the content of humic acid and make steady growth.关键词
