摘要

应用田间长期定位试验

研究了5种耕作措施对东北农田黑土入渗速率的影响。结果表明

传统耕作为代表的平翻和旋松耕作的垄台容重最小

表层土壤稳定入渗速率高于其它3种耕作措施

分别为9.20mm/min和7.31mm/min。免耕垄台和垄沟的容重虽较高

但均具有较高的稳定入渗速率。在夏季进行垄沟深松少耕

可显著提高垄沟的稳定入渗速率。免耕和少耕是高效的水土保持耕作措施。

Abstract

This study determined infiltration into soils on black farmland under different tillage systems by long-term experiment. The moldboard plough and rotary tillage being representative of conventional tillage systems induced a lowest bulk density in ridge. Surface stable infiltration rates under moldboard plough and rotary tillage were 9.20 and 7.31 mm/min

respectively

which were higher than the others. Although no-tillage induced a higher bulk density in ridge and furrow

it had a relatively high stable infiltration rate. Re-duced tillage could significantly increase stable infiltration rate in furrow because it loosed the furrow in sum-mer. These indicate that no-tillage and reduced tillage are effective tillage systems of soil and water conserva-tion.
