| 摘 要： | 在陇中半干旱区探讨了补水和施加保水剂对不同层次土壤水分利用效率及马铃薯产量的影响.结果表明,马铃薯生育期的耗水主要集中在80 cm土层内,80 cm土层以下土壤含水量变化不明显,基本不被马铃薯吸收利用.施用保水剂处理的群体水平水分利用效率和产量水平水分利用效率均最高,分别为42.73 kg/(mm·hm2)和94.21... |

| Abstract: | The effects of water retaining agent and water supplement on potato yield and water use efficiency(WUE)in semi-arid area was conducted.The results showed that water consumption of potato during the growing season concentrated in the 80 cm soil depth mainly.The change of water content below 80 cm layer was not significant and was almost not absorbed by potato basically.Under the condition of water retaining agent treatment,water use efficiency(WUE) at population and yield level of potato were the highest,42.... |
