浑水灌溉浑水灌溉irrigation with water of high silt contenthunshui guan，gai浑水灌溉(irrigation with water ofhigh silt eontent)利用多沙河流汛期浑水进行灌概。它具有提高水资源利用率，防早保墒，增加地力，改良土壤，保持水土，分散水势，减轻水患的作用。浑水灌溉的技术要求①掌握取水含沙界限:据陕西省径、洛、渭三大灌区实践，玉米棉花生育期内可引用含沙量在35%(重量比)以下的浑水进行灌溉，而在玉米苗期，棉花蕾期，含沙界限应控制在25%以下。②控制淤泥厚度:旱作实行浑水灌溉，高杆作物淤层宜厚，矮杆作物宜薄。从径、洛、渭三大灌区资料分析。对于玉米，淤泥厚度可为5一7厘米，对于棉花，淤泥厚度可为3一6厘米。水稻实行浑灌，拔节后淤泥厚度可为8一12厘米。③提高落淤质量:影响落淤质量的主要因素是单宽流量、田面比降、淤区面积，在田面比降相同的条件下，为了提高落淤质量应适当加大单宽流量，以避免出现淤厚不均和分选顺粒的情况。④节约用水:径惠渠试验，沟灌通气性较畦灌良好，有利于作物生长发育。小畦沟灌水流集中，流速较快，输沙能力增强，泥沙落淤均匀.既有利于改土，又能节约用水。沟灌规格一般和清水灌溉要求一样。浑水渠系规划设计的特点①清、浑兼引渠道既要适应清水冲刷的特点，又要考虑浑水落淤的可能。要防冲也要防淤。允许渠道有冲有淤，在一定的时期内冲淤平衡。②要结合地形条件，尽可能将渠道布置在较高地带或布置在具有较大坡度的地面上，以便增大比降，控制较多的自流灌溉面积，使水流具有较大的流速。③适应高含沙洪水历时短、来量大的特点，引水口应有利于引用较多浑水，尽量减少渠道级数，增大设计流量，全灌区干支渠同时放水，斗渠全开，使水流尽快进入田间。浑水灌溉的水源一是汛期河水，二是水库排出的浑水。水库排浑主要是汛前水库为腾空迎汛而排出的浑水.以及汛期泄洪而排出的浑水.洪峰经水库调立长，滞，泄量变得小而均匀，沙峰经水库调滞，时间灌溉，因此水库下游的灌区可于较长时间内进行浑水和基有的水库还采用水力吸泥，高渠拉沙，泄空冲届行浑流冲刷等方式将库内滩槽淤积排出库外，也可遥卜)水灌溉。(张:
