摘要
近年来研究表明调亏灌溉可以增加产量、提高果实品质,通过滴灌技术和调亏灌溉理论相结合的方法研究调亏灌溉对滴灌葡萄生长与产量的影响,对滴灌技术的深入研究有一定的理论价值。通过田间小区试验,对正常灌溉和调亏灌溉处理下滴灌葡萄的生长变化、产量变化进行研究,结果表明:在葡萄萌芽期、抽穗期控制灌水下限为田间持水率的40%,葡萄产量最大,达到829.3 kg/667 m2;在抽穗期、开花期分别控制灌水下限为田间持水率的45%、50%可以起到疏花的作用,果粒重和果实直径最大,但是产量最小,为699.1 kg/667m2;在着色成熟期控制灌水下限为田间持水率的45%,葡萄产量为795.6 kg/667m2。
Research in recent years shows that regulated deficit irrigation can increase the yield and improve fruit quality of fruit trees.The paper analyses the growing character and yield variation of grapes under drip irrigation.The experiment reveals that the limit of irrigation is controlled at 40% of the field capacity during the grape sprouting period and the heading period,and the grape yield is the biggest,up to 829.3 kg/667m2.The limit of irrigation is controlled at respectively 45% and 50% of the field capacity during the bloom and fruit swelling period,which can make the flower reducing,increasing the fruit weight and having the biggest fruit,but the yield is the smallest one（699.1 kg/667m2）.The limit of irrigation is controlled at 45% of the field capacity during the dyeing mature period,and the yield is 795.6 kg/667m2.
