| 摘 要： | 通过苜蓿、猫尾草、籽粒苋分别与牛粪混合堆腐进行改性处理,研究堆腐过程中有机组分的动态变化。结果表明,绿肥与牛粪混合堆腐可以使堆腐产物中水溶性有机组分的含量增加,提供更多的营养物质供作物直接吸收利用,并且显著提高了堆腐产物持续生成水溶性胡敏酸的能力,其中添加苜蓿堆腐处理产生的水溶性有机组分含量大于其它处理。添加苜蓿和猫尾草堆腐不但可以增加堆腐产物中碱溶性有机物和碱溶性胡敏酸的含量,提高堆腐产物的HA/FA值,而且在堆腐后期可以降低堆腐产物中碱溶性富里酸的减小,添加籽粒苋堆腐处理这种作用不明显。

| Abstract: | Cow manure separately composted with alfalfa,timothy and redroot amaranth,to research the dynamic changes of organic components during composting.After cow manure composted with the three kinds of green manure,the water-soluble organic components in composting products were increased.And it could provide more nutrients which could be absorbed directly by crops.Also water-soluble humic acids were produced obviously in composting products.The effect of the treatment of composting with alfalfa was the best.Cow manure separately composted with alfalfa and timothy,not only the alkali-soluble organic matter and humic acids were increased,but also the alkali-soluble fulvic acids were decreased at the late composting.The effect of the treatment of composting with redroot amaranth wasn’t obvious. |
