以冬小麦为例，对不同灌水定额方案，做了数值模拟计算，预报了冬小麦最优灌溉制度。

And with winter wheat, a few irrigation quota schemes are numerically simulated, and the optimization irrigation schedule of winter wheat is predicted.

可见冠层对喷灌水量分布的影响不容忽视，有必要进一步弄清它们之间的影响机理，这将为喷灌制度的设计提供重要依据。

Obviously, it is not ignored for the distribution of the sprinkler water by the canopy. It is important that the mechanism of the effects between them is researched accurately.
