| Abstract: | Conservation tillage is an effective technique for increasing crop yield in arid areas.The objective of this field experiment was to compare the effects of three different tillage systems(no tillage,reduced tillage and conventional tillage) on soil temperature,soil water content and crop yield in arable black soil region of Hailun County,Heilongjiang province from 2004 to 2009.The result showed that no-tillage with mulch(NT) and reduced tillage(RT) under soybean and corn rotation system,the soybean yield in... |
