摘要
通过田间试验研究了饼肥与化肥不同配比施用对烤烟田土壤根际酶活性和烟叶品质的影响。结果表明,饼肥和化肥配施与纯施化肥相比,能显著提高土壤中的蛋白酶、脲酶、磷酸酶、转化酶活性,改善了烟叶品质,其中以50%饼肥和50%化肥配施效果最好。
An field experiment was carried out to study the effect of chemical fertilizer combined with cake fertilizer on soil enzyme activity. Results indicated that cake fertilizer combined with chemical fertilizer could increase the activity of protease urease alkline phoshpatase and invertase. The treatment of 50% N of cake added 50% N of chemical fertilizer was optimum combination.
