摘要
[目的]为了研究粪肥处理对棉秆腐熟后电导率、有机碳、全氮含量、腐殖化度等腐熟特征指标的影响。[方法]采用牛粪和棉秆的不同质量比进行发酵处理。[结果]粪肥添加量最低时发酵产物电导率高;10 g/25 g粪肥处理下有机碳含量最大,而15 g/25 g粪肥处理下有机碳含量最小;10 g/25 g粪肥处理下碳氮比值最大,5 g/25 g粪肥处理下最小;在允许的范围内,随着粪肥添加量的增加,发酵产物的腐殖化度增加。[结论]采用合理的粪肥添加量来促进棉秆的腐熟,可以为其他有机物料的促腐提供参考方法。
[ Objective ] The research aimedto study the effects of three cow dung treatments on some maturity characteristic indexes of cotton stalk, such as conductivity, organic carbon, carbon nitrogen ratio, humification, etc. [ Method ] The treatments of different quality ratio of cow dung and cotton stalk feimentation were adopted. [ Result] Fermentation products had a high conductivity when manure addition was less. The organic carbon content was maximum under 10 g/25 g treatment and minimum under 15 g/25 g treatment. Meanwhile, it had a maximum C/N ratio under 10 g/25 g treatment and a minimum C/N ratio under 5 g/25 g treatment. In the allowed range, with the increase of manure addition, the humification of fermentation products was increased too. [ Conclusion] A rational additive amount of cow dung could improve the compost of cotton stems, Which could provide reference method for the pomotion of tire decomposition of other organic materials.
