农田秸秆覆盖后作物苗期棵间土壤蒸发明显减少，使旺盛生长期可利用水分增加，提高了水分的利用率。
Because soil evaporation was reduced obviously in the earlier stage of crop growth, available water was increased during flourishing stage of crops. So water use efficiency was increased.
结果表明：①地灌后地表蒸发与植被层的蒸腾更旺盛，散失的水分更多；
The results are as follows: (1) The evaporation and transpiration were larger after ground irrigation, which will speed up the loss of soil moisture content;
或方或圆的灌溉农田长满庄稼，呈现深蓝色，说明旺盛生长的植物正在汲取水分并将其蒸发。
Fields of irrigated crops are dark blue squares or circles, showing that the growing plants are taking up and transpiring water.
