铬革屑制备功能有机肥改善荞麦品质的研究

Study on Improving the Quality of Buckwheat by Functional Organic Fertilizer Prepared from Chrome Shaving

利用废弃铬革屑制备功能型土壤有机肥,并在荞麦上进行肥效试验。结果表明:革屑功能型有机肥可以提高产量,增加荞麦对N元素的利用效率,提高生物活性成分——黄酮类化合物的含量,并在允许范围内增加三价铬的含量。

In this paper, functional organic fertilizer was prepared by using chrome shaving as raw material, and the efficiency of fertilizer was carried out in buckwheat. It is found that the functional organic fertilizer can increase the yield of buckwheat. And the functional organic fertilizer can not only improve the utilization ratio of nitrogen element but also improve the content of the flavonoid compounds which are the biologically active constituents. The content of trivalent chromium in buckwheat is also increased in the allowable range.
