Abstract
A field experiment was conducted to evaluate the effects of no-tillage(NT) and reduced tillage(RT) on soil water storage,water use efficiency(WUE),and their effects on corn yield in Northeast China.Soil moisture was measured from May to September in 2009,and water storage and WUE was calculated.The results showed that,compared to conventional tillage(CT),soil water content under NT was higher in 0~90 cm soil layer and the difference decreased with soil depth increasing.There was no difference at the depth of 190 cm.Soil water storage was mainly influenced by rainfall and soil tillage,thus soil water storage was lower in windy and rainless spring and autumn,and they followed the order of NTCTRT.The soil water storage order changed to RTNTCT in rainy summer season.The furrow was loosened by zonal tillage in RT,which increased infiltration and benefited agriculture.LAI in NT was respectively 0.22 and 0.26 lower than those in CT and RT.The evapotranspiration(ET) in RT during the growing season was the highest.The corn grain yield and WUE in CT were 30% and 17% higher than those in NT,and 29% and 11% higher than those in RT,respectively.The corn grain yield in the three tillage systems were significantly different(P0.05).So NT and RT is infeasible in corn production,and CT is still undeniable soil tillage practice with higher yield and WUE in arable black soil cropping system in this region.
