| 摘 要： | 在河西走廊的盐化潮土上设置了糠醛渣的改土培肥田间试验,结果表明:甜菜施用糠醛渣与施用化肥比较,土壤容重、全盐、pH分别降低0.21g cm-3、0.36g kg-1、0.37;总孔度、自然含水量、贮水量、团粒结构、有机质、速效N、P、K、CEC分别增加7.93%、79.90g kg-1、131.95m3 hm-3、4.75%、0.61g kg-1、12.96mg kg-1、1.24mg kg-1、6.78mg kg-1、1.89cmol kg-1。施肥成本降低90元hm-2,施肥利润增加1716元hm-2。且施用糠醛渣能提高土壤中磷的活性和磷的利用率。 |

| Abstract: | An experiment for improving soil fertility was conducted in field to test the effect of furfural dreg on the salt contents in the Hexi Corridor.The result shows: Compared with the use of the furfural dreg and the chemical fertilizer for beet,we found that soil bulk density,salt content and pH were reduced by 0.21g cm-3,0.36g kg-1 and 0.37,respectively.Total porosity,water content,the amount of stored water,aggregate structure,organic matter,available N,P and K and CEC increase by 7.93%,79.90g kg-1,131.95m3 hm-2,4.75%,0.61g kg-1,12.96mg kg-1,1.24mg kg-1,6.78mg kg-1 and 1.89cmol kg-1,respectively.The cost is reduced by 90 yuan hm-2,while the profit increases by 1716 yuan hm-2.In addition,the utilization rate of phosphorus and the content of available phosphorus were improved by using the furfural dreg. |
