| 摘 要： | 针对关中灌区农业种植特点及灌区灌溉现状,提出提高田间水利用效率的节水模式,主要包括：采用土地平整技术提高田间平整精度到3cm,畦田长度控制在50～100m内,在畦田长大于100m的区域推广波涌灌技术,对于小麦等密植作物推广使用喷灌技术,灌溉水量采用0.65倍水面蒸发量,对于果树等经济作物可选用滴灌和小管出流等微灌技术。...

| Abstract: | Based on comprehensive analysis of agronomic practices,agricultural plant structure and current irrigation statue in this area,five methods are recommend to improve field water use efficiency,which include using land-leveling technology to control field leveling precision less than 3 cm,controlling border length within a range from 50 to 100 m,using surge irrigation method when border length longer than 100 m,using sprinkler irrigation method for high population planting crops such as winter wheat with a ir... |
