Abstract：This paper investigated the impact of different irrigation methods on soil density, soil porosity, aggre-gate stability, seed abscission and yield of peanuts in 2014—2015. Three methods:micro-spray irrigation, mobile-pipe irrigation and no irrigation were tested. The results revealed that compared with mobile-pipe irrigation, the micro-spray irrigation reduced soil density, stability of aggregates smaller than 0.25 mm, and abscission of seeds by 7.6%, 6.4%and 66.8%respectively, whereas the associated soil porosity increased by 8.4%. There was no sig-nificant difference between the yields of the two irrigations treatments. Considering the yield, the change in soil physical properties and the seed abscission rate, we feel that the micro-spray irrigation is beneficial to peanut har-vest in our experiment.
