摘要: 在科尔沁沙地试验了经发酵的酒精废渣对沙地土壤理化性状及作物生长和产量的影响。结果表明:该废渣中含有较高的有机质和作物所需的氮磷养分,施入沙地土壤后,经过一个生长季,土壤的保水性能明显提高、容重降低0.02~ 0.16 g·cm-3、pH值下降0.05~ 0.75、有机质增加0.05%~ 0.58%、全磷和全氮分别增加0.002%~0008%和0.002%~ 0.072%;适量施用该废渣可以提高作物的产量,但过量施用对小麦和荞麦生长发育有抑制作用。

Abstract: The fermented waste residues from alcohol production with abundant of organic carbon, nitrogen and phosphorus were input to sandy farm land, on which wheat, mung bean and buckwheat grow. After a growing season (about 180 days), the soil porosity, water-holding ability increased notably, soil organic carbon, total N, available N, total P, available P increased by 0.05%~0.58%, 0.002%~0.072%, 10.1 ~148.8 mg·kg -1, 0.002%~0.008%, 5.63 ~29.30 mg·kg -1 respectively under control condition. The pH decreased 0.01~0.57.The residues help to improve the crops production but may do harm to the crops when over using.

Key words: waste residues from alcohol production, sandy land improvement, wheat, buckwheat, mung bean, Horqin Sandy Land
