摘　　要：阜蒙县发展玉米生产必须克服严重干旱和水资源短缺的影响,以节水为中心,建立合理的耕作制度,提高土壤蓄水纳肥能力和自然降雨的利用率。通过玉米苗期中耕深松试验,研究中耕深松对土壤水分转移及对玉米生长和产量的影响,探求提高土壤蓄水、缓解春旱、促进苗期生长、实现玉米增产增效的最佳途径。结果表明:中耕深松可以改善土壤物理性状,增加蓄水纳肥能力,缓解旱情,促进作物生长及产量提高。The development of maize production in Fumeng county must overcome severe draught and water resources shortage,taking water saving as the center,establish a reasonable farming system,which could improve the soil water and fertilizer storage capacity and the utilization rate of natural rainfall.In this paper,the effects of soil moisture transfer and maize growth and yield were studied through the experiment in maize seedling stage,and the best way to improve soil water storage,alleviate spring drought,promote the growth of seedling stage and realize maize yield and efficiency was explored.The results showed that intertillage and subsoiling could improve soil physical properties,increase water and fertilizer storage capacity,alleviate drought and promote crop growth and yield.The soil water storage capacity increased gradually with the increase of depth of tillage.
