6) irrigating limited
限量灌水
1.
This paper studied the effect of phosphorus supplied on growth development, yield, photosynthesis and water use efficiency of winter wheat under condition of irrigating limited.
通过研究限量灌水情况下磷营养对冬小麦生长发育、产量、光合作用和水分利用效率的影响，结果表明：干旱情况下，磷由于满足了冬小麦的物质生产过程对营养元素的需求，因而促进其生长发育，增加了小麦分蘖数和根数，提高了叶面积、生物量、光合速率、产量和水分利用效率；在不同水分条件下，施磷均可提高小麦光合速率，其主要原因是提高了叶肉细胞光合活性。
补充资料：地下水回灌
简称“回灌”、“人工引渗”。降雨径流、河流来水、灌溉退水、经处理后的城市生活污水和工业废水等，通过地面入渗或水井注入对地下水源的人工补给工作。可控制地面沉降，防止海水入侵含水层，改善地下水水质，调节地下水温，保持地热水、天然气和石油地层的压力等。
