摘 要：
为了给堆肥施用和土壤有机质管理提供依据,设计盆栽试验定量分析评价了作物对堆肥有机质的利用状况。结果表明,堆肥和作物之间存在相互选择性;未栽培作物组与栽培作物组中有机质消耗率分别为0.5%~42.0%和8.0%~99.9%,作物栽培显著促进了有机质的消耗;尽管不同作物对有机质的消耗存在差异,但作物生长过程中都消耗了大量的有机质(达90%);一次种植后盆栽基质中有机质即降至4.2%~12.6%,接近耕作层土壤的普通有机质含量水平。可见,作物栽培对有机质的消耗很大,应该增强和坚持堆肥施用,防止土壤有机质过度消耗。

摘 要：
In order to provide basis for compost application and management of soil organic matter,the utilization of organic matter in compost was quantitatively analyzed by quantitative analysis in pot experiment. The results showed that there was a mutual selectivity between the composts and the crops.The group without crop cultivation had organic matter consumption rates of 0.5%-42.0%,while the group with crop cultivation of 8.0%-99.9%,so a crop cultivation significantly promoted the consumption of organic matter.Although there was difference among the consumptions of organic matter for the crops, but large amounts of organic matter was consumed in the process of crop growth( 90 %). The organic matter content were decreased to 4.2%-12.6% after one planting cycle,closing to the ordinary level of organic matter content in cultivate layer of soil. Therefore,crop cultivation had a serious consumption of organic matter,compost application should be heightened and persevered,preventing an excessive consumption of soil organic matter.
