Urease and invertase activities were higher after harvest than before sowing, however acid phosphatase activity was lower after harvest.
玉米收获后，土壤转化酶、脲酶均高于播前或与播前相当，而酸性磷酸酶活性则低于播前。
With same application rate of chemical fertilizer, application of organic fertilizer could increase urease and invertase activities, but decrease acid phosphatase activity.
在同样化肥水平上增施有机肥能增加脲酶、转化酶活性，而降低酸性磷酸酶活性；
In moderate and high drought stress and waterlogging conditions, neutral invertase, acid invertase and sucrose synthase activity reduced and protease activity enhanced.
中度、重度干旱胁迫和淹水条件下，中性转化酶、酸性转化酶和蔗糖合成酶降低，蛋白酶活性增加。
