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。
The functional soil organic fertilizer was prepared using discarded chrome shavings and the fertilizer efficiency test was conducted on buckwheat. The results showed that the leather-borne organic fertilizer could increase the yield, increase the utilization efficiency of the elemental N, increase the content of the bioactive ingredient-flavonoid, and increase the trivalent chromium within the allowable range.
