摘要

为探究长期秸秆覆盖免耕对黑土坡耕地土壤结构的影响以及水土保持效应

通过秸秆覆盖免耕(NT)和传统顺坡耕作(CT)2组长期定位田间试验

对土壤结构、土壤保水能力、保土效应作对比分析。结果表明:NT与CT相应性状比较

土壤容重没有显著增加(P＞0.05)

在0—20 cm土层

虽总孔隙度和非毛管孔隙度低

但增加了土壤毛管孔隙度和水稳性大团聚体(WR0.25)含量

WR0.25含量和平均重量直径(MWD)差异均达到显著水平(P＜0.05);分别提高了垄台土壤初始入渗和稳定入渗速率28.8%

24.7%;0—10 cm土层

饱和含水量和田间持水量差异均达到显著水平(P＜0.05);减少了产流次数、径流量和土壤流失量分别为11次

86.6%和98.9%

有效地遏制了水土流失。研究结果表明

长期连续秸秆覆盖免耕是一项有利于土壤结构稳定和遏制土壤侵蚀的黑土地保护措施。

Abstract

To reveal the influence of long-term straw mulching and no tillage (NT) on soil structure and soil and water conservation of Mollisols sloping farmland

two 14 years long-term experiments

including NT and conventional tillage (CT)

were conducted to compare soil structure

water conservation capacity and soil retention effect. The results showed that compared with CT

the soil bulk density of NT did not increased significantly (P>0.05). The total porosity and non-capillary porosity of NT were lower than those of CT in 0-20 cm layer

while NT increased the capillary porosity and content of water stable aggregate (WR0.25)

and the differences in WR0.25 and mean weight diameter of soil aggregate (MWD) between the two treatments were significant (P<0.05). Meanwhile

NT increased the initial infiltration rate and stable infiltration rate of ridge platform by 28.8% and 24.7%

respectively. And in 0-10 cm layer

the differences in saturated water content and field capacity between the two treatments were significant (P<0.05). In addition

the number of runoff production

runoff and soil loss decreased by 11 times

86.6% and 98.9% in NT

respectively. This study indicated that long-term continuous NT was an effective practice to stabilize soil structure and prevent soil erosion in Molliosls.
