| 摘 要： | 灌水安排的理想情况是当实际的土壤水分消耗量达到预定的允许耗水量时进行适时灌溉,灌溉水量应当是将土壤湿度水平返补至预期的水平(通常为田间持水量)时需要的水量.该研究给出了基于土壤类型、管理允许耗水量以及田间观测方法确定允许耗水量的计算依据.介绍了基于历史月度参考腾发量ET数据、当前(日)参考腾发量ET数据,或者应用土壤水分平衡方法、土壤湿度或土壤张力传感器来确定绿地植物灌水周期的方法.给出了基于历史月度参考腾发量ET数据、当前(日)参考腾发量ET数据及湿度传感器来确定灌水周期植物净需水量和灌水周期基础灌溉需水量的计算过程.为避免地面径流,可通过观察的方法或者通过基本渗吸速率法确定小循环的数量,并确定小循环之间的浸透时间.管理者应该对园林绿化进行定期观测,并对灌水安排做出必要的调整.

| Abstract: | Ideally,irrigation should occur when the actual soil moisture depletion reaches the target management allowable depletion.The amount of irrigation water to apply is the amount required to bring the soil moisture content back to the desired level.Under normal irrigation,this desired level is field capacity.This article presented the methods for defining allowable depletion that can be indirectly based on soil type and target management allowable depletion(MAD),or directly by the field method. Then the method... |
