饼肥及其与化肥的适当配合施用,能增强烤烟根系活力,增加叶绿素含量,促进硝酸还原酶活性提高,使下部叶增厚,上部叶展开,从而有利于克服下部叶大而薄,上部叶小而厚的缺陷;用量,以饼肥氮和化肥氮各占50%的配比效果最好。
The cake fertilizer and its combination with chemical fertilizers could remarkably raise vigor of roots,increase the chlorophyll content and the activity of nitrate reductase.The comparison on effects of three kinds of cakes showed that the rapeseed cake was beatter than sesame seed cake and cotton seed cake.
