室内模拟条件下玉米秸秆的分解特征及物质组成变化
Characteristics of decomposition and variation of material composition of corn straw in laboratory simulation experiment
摘要
Abstract
The changes of decomposition rate ,crude fiber and total potassium content of corn straw were studied in a laboratory simulation experiment .The results showed that the decomposition rate of corn straw in all treatments exhibit-ed an increasing trend along with the extension of time .When other conditions were coincident ,the mean decomposing rate in the treatments incorporated with microbial agents was higher than that in the treatments without microbial agents , and the mean decomposing rate in the treatments with the straw length of 1 cm was higher than that in the treatments with the straw length of 3 cm .The general trend of crude fiber of all treatments was declining during the decay period .When other conditions were coincident ,the mean content of crude fiber in the treatments with microbial agents was lower than that in the treatments without microbial agents ,and it was the lowest (31 .57% ) in the treatment with microbial agents in which C/N ratio was 25 and the straw length was 1 cm .When other conditions were coincident ,the content of total potassi-um in the treatments with the straw length of 1cm was higher than that in the treatments with the straw length of 3 cm .关键词
