农业科技园灌溉排水方法研究与应用——以南京农业大学白马教学科研基地为例

Research and Application of Irrigation and Drainage Method——A Case Study of the Baima Base for Teaching and Scientific Research of Nanjing Agricultural University

园区灌溉试验田位于东区南侧和西区,西区规划为农业试验田,其中主干道路以北为水田,以南为旱田,西区灌溉试验田总面积74.6hm^2,规划两套灌溉引水方案:自流灌溉方案和提水灌溉方案,其中提灌引水规划明渠和管道两种田间渠系方案。南京地区普遍采用种植中稻,试验田按水田计算灌溉用水量,采用衬砌渠道,灌溉水利用系数按0.65计算。旱地按照小麦进行设计,在一般年份不需要灌溉,特枯年份需要少量灌溉计算。论文从工程投资,运行费用,节约土地等方面进行方法研究。

The irrigation field is located in Agricultural Science and Technology Park on West district which planning for agricultural experiment field and the south side of East district, paddy field by the trunk road of and the dry land by other side. West irrigation plots total area of74.6h m2, two sets of planning of irrigation schemes, gravity and lift irrigation, the irrigation water diversion plan two field canal scheme, open channel and pipe. Middle-season rice commonly planting in the Nanj ing area, field irrigation water is calculated as paddy fields by using efficiency 0.65. Dry land is designed according to wheat, no irrigation is needed in the general year, and a small amount of irrigation is needed in the dry year. This paper study on the project investment, the operation cost, the land saving, water saving, time saving, labor
