摘要
通过在室内培养条件下研究菜籽饼粕对土壤有机质和土壤酶活性的影响,结果表明,将菜籽饼粕加入第四纪黄壤和中性紫色土之后,土壤有机质含量先增后降;土壤酶活性的变化因酶的种类而异:蛋白酶和脲酶活性在初始期显著提高,之后降低;过氧化氢酶同样在短时间内提高,然后保持恒定状态;而蔗糖酶活性则随着菜籽饼粕的加入受到了抑制,一直呈下降趋势,这可能与菜籽饼粕的用量和抗营养成分有关。
The effects of rapeseed cake on soil organic matter and activities of soil enzyme under indoor cultivation condition were studied. The results showed that when the rapeseed cake mixed with quaternary yellow soil and neutral purplish soil, the content of organic matter increased first then decreased. The change of soil enzyme activity varied by the type of enzyme： the activities of protease and urase were improved significantly in a short period of time and declined later. The activity of catalase also could be improved in a short time, and then maintained a steady state. The activity of invertase was inhibited when the rapeseed cake was mixed in and showed a declining trend, which may be relevant to the quantity and anti-nutrients of rapeseed cake.
