摘  要:
从节水灌溉的基本原理着手,运用农田水量平衡原理,以板蓝根灌区为例、洪水河灌区益民灌溉试验站多年试验资料为依据,作出适合当地板蓝根的灌溉预报。结果表明,板蓝根的灌溉定额为2 580 m3/hm2,夏灌1次水的灌水时间为6月中旬,灌水定额为1 290m3/hm2;夏灌2次水灌水时间为8月下旬,灌水定额为1 290 m3/hm2;与常规灌溉模式相比,节水1 200 m3/hm2,增产值5 755元/hm2,节水增产效益显著。

摘  要:
Starting with the basic principle of water-saving irrigation,principle of field water balance was applied.Taking indigowoad root as an example,irrigation forecast suitable for indigowoad root was conducted according to the historical data in Hongshuihe irrigation district.Result showed that the irrigation quota of indigowoad root was 2 580 m3/hm2.The first time of irrigation was mid June with irrigation quota being 1 290 m3/hm2;the second time of irrigation was mid August with 1 290 m3/hm2 irrigation quota.Compared with the conventional irrigation mode,it saved 1 200 m3/hm2 water,and the output value increased by 5 755 yuan/hm2,which showed that the benefit of water saving and yield increase was significant.
