the results show that the activities of soil invertase and soil urease were closely correlated with soil fertility;
相关分析表明:在三种植物群落中土壤脲酶、土壤蔗糖酶活性与土壤肥力成正相关;
however the soil invertase activity between rape and wheat fields was at the same level, which showed that the plant did little influence to soil invertase activity.
油菜地各处理土壤过氧化氢酶活性高于小麦地相对应处理,而不同作物种植方式对土壤转化酶影响不明显。
effect of ethanol concentration on the soil invertase activity and effect of different substrate(saccharose) concentrations on the relationship between invertase activity and ethanol were studied.
研究了不同浓度乙醇对土壤转化酶活性的影响以及不同底物(蔗糖)浓度对乙醇与转化酶活性关系的影响。
