摘要
本文探讨了农田水分的动态变化规律及其对作物生长发育的影响,分析了农田水分利用效率及潜力。通过试验,研究了水分利用效率与地力的关系,认为地力不足是影响农田水分利用效率的重要原因,并相应地提出了开发农田水分生产潜力的途径。
The paper studies water dynamics in soil and their effects on crops,analyzing waterefflciencies and latent productivity of water by experiments.It is found out that low fertili-ty affects water efficiency. In the last part the author proposes some measures to raise thelatent productivities of dryland water.
