旱地玉米免耕整秸秆半覆盖技术经济效果评价

Technical Economic Evaluation of No-tillage with Mulching

应用比较分析方法，对免耕整秸秆半覆盖技术进行了技术经济效果评价。结果认为，该项目具有蓄水保墒、保持水土、培肥土壤、增产显著的技术效果；也具有节能省工、减少费用、效益显著的经济效果。该项目技术先进、实用，经济上合理，生产上可行，适应范围广，可操作性强，适合在我省及我国北方旱作地区普遍推广。

Technical economic evaluation on no-tillage with stalks mulching was made with comparative analysis method in this paper. Results indicated that the advantages of no-tillage with stalks mulching were as follows. 1)Decreased water evaporation from the soil and increased water infiltration into the soil. 2)Reduced soil erosion. 3)Improved soil fertility. 4)Increased grain yield. 5) The investments in energy, machinery, and labours were reduced. This technique was advanced, practical. It is reasinable in economy. It is suitable to extend this technique in semi-arid regions.
