| 摘要: |
| 于2014―2015年度麦茬花生生长季，设置移动式管灌、微喷带灌溉和不灌溉3种处理，研究了不同灌溉方式下农田土壤体积质量、土壤孔隙度、水稳定性土壤团聚体组成、花生产量和花生落果率的变化。结果表明，与移动式管灌处理相比，微喷带灌溉处理的土壤体积质量、粒径小于0.25 mm水稳定性土壤团聚体数量和花生落果率分别降低了7.6%、6.4%和66.8%，土壤孔隙度增加了8.4%，而2处理间花生产量没有显著差异。综合考虑花生产量，土壤物理性状和花生落果率的变化，微喷带灌溉是试验条件下能够降低花生收获难度的灌溉方式。 |

| Abstract: |
| This paper investigated the impact of different irrigation methods on soil density, soil porosity, aggregate 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 significant 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 harvest in our experiment. |
