摘要
通过实验研究了施用油母页岩废渣对大豆产量的影响,试验结果表明,施用油母页岩废渣能促进大豆生长发育,显著提高大豆产量,其中,中量油母页岩废渣21t/hm2·a配施氮磷钾化肥的效果最好,其增产率达184.03%,但随着油母页岩施用量的增加,其增产效果下降。
Effects of oil shale ash application on soybean yield were investigated under field plot experiment. The results showed that applying oil shale ash had significant effect on the soybean yield compared with the control and other treatments. When applying the oil shale ash of 21 t hm-2.a-1,the improvement effect was the best than applying other fertilizers with increasing yield of 184.03 percentages, but with the increasing of applying dose of oil shale ash, the yield-increasing effect is down.
