Effects of the Different Organic Materials on the Combined States of Humus in Black Soil
摘要
Abstract
Humic substances( HS ) are the most important components of soil organic matter and soil carbon sequestration, So it is one of the hot issues of international affairs and Low-carbon Society. Application of organic materials is an important practice for maintaining and/or improving the physical, chemical and biological performances of HS in soils. In this paper, the pot experiment was conducted to study the effect of the different organic materials on the combined states of humus in black soil. The results showed as follow: Compared with control treatment (CK), application of herb residues increased contents of loosely combined soil humus substances, and significantly higher than CK in the first year, after five years used of animal excrement increased the content of loosely combined markedly. The ratio of HA and FA of loosely combined was significantly difference in the first year. E4/E6 of every treatment was also significantly different in the first year. The content of unitedly combine humus of organic materials were all notable lower than CK in the first year, but significantly higher than CK three year later, E4/E6 indicated obvious difference until the fifth year, among them, herb residues, animal remnant significantly higher than others, and there were no significant difference among them. There were no difference in the content of the stably combined, but the composition was different. Compared to CK, the content of tightly was increased visible after application of organic materials a year later. The ratio of loosely and tightly showed herb residues dramatically enhanced the ratio, woody residues and animal excrement were observably lower than CK in the first year, and there was no obvious difference with the time going on .关键词
