储水灌溉
storage irrigation
guan，gai溉(storage irrigation)依靠灌水或拦蓄自然降水把水分储存于土壤中以供作物吸收利用的一种灌溉方法。在中国北方干早半干早地区，水源不足，储水灌溉是一项重要的抗早措施。 麦收、秋收后翻耕纳雨，耙籍保墒，储蓄足够伏雨或秋雨供下茬作物来春需用(即伏雨、秋雨春用)，是中国北方采用较广的储水措施。但对一些自然降水少、储水效果差的地区和雨季有棉花、玉米等作物生长的土壤，需在播种前进行人工储水灌溉，用得最多的是棉田和其他春种田的冬灌、早春灌和麦田的播前灌。 为了充分发挥储水灌溉的作用，必须根据当地的气候、土壤、地下水位等情况，正确掌握灌水时期，灌水量和灌水技术。棉田、春小麦田和其他春种田的储水灌溉可以在上壤开始封冻前进行。一般灌水定额为90一120毫米，严禁大水漫灌。井灌区多采用沟灌，沟长20一30米。渠灌区采用畦灌，畦宽4米，长3()米左右。冻前储水灌溉应与深耕施肥结合进行，一般灌后及时深翻，耙地保墒。若在早春进行储水灌溉要抓紧在刚解冻时进行，灌水时间要求在播种前一个月左右，以免播种时温度过低，水量以60毫米左右为宜。沙质仁和盐碱地不宜在冬季储水灌溉，应采取春灌。 (郭国双)
