| Abstract: |
| Systematical study was made on the influence of 4 kinds of combination fertilizer from different organic wastes on physical and chemical properties of grey brown desert soil and corn output and economic benefits.The results show that it is useful to apply 45.00 t·hm-2 combination fertilizer from organic wastes like furfural residue,sheep dung,corn stalk and rapeseed cake in the volume ratio of 0.50∶0.25∶0.20∶0.05 after treatment of high temperature and fermentation.Compared to CK(without application),soil total porosity,granule structure and water storage increase by 8.69%,8.73% and 91.36 m3·hm-2; soil organic matter,available N,P and K and CEC increase by 5.86 g·kg-1, 21.42 mg·kg-1, 7.47 mg·kg-1, 42.67 mg·kg-1 and 13.07 cmol·kg-1; and corn output,output value and profit increase by 2.03 t·hm-2,0.19×104 yuan·hm-2 and 0.08×104 yuan·hm-2, respectively; while soil unit weight reduces by 0.28 g·cm-3. The application of domestic rubbish causes a tendency of heavy metal enrichment,but long\|term use of furfural residue,mushroom dregs and sawdust does not have such an effect. |
