摘　　要：通过日光温室内的再生水滴灌试验,研究了再生水滴灌下水质、灌水周期和滴灌带埋深对番茄产量、品质和灌溉水分生产率的影响。结果表明,再生水灌溉增加了番茄产量,提高了灌溉水分生产率,一定程度改善了果实的可溶性糖和可滴定酸度等口感指标,对Vc和可溶性固形物等营养指标无明显不利影响。灌水周期的缩短和滴灌带埋深的增加都会促进番茄产量和灌溉水分生产率的增加。对日光温室番茄而言,以较短的灌水周期和较深的滴灌带埋深进行再生水滴灌能够获得较好的节水增产效果,且对果实品质无不利影响。Field experiments were conducted in a solar-heated greenhouse to investigate the influences of water quality, irrigation intervals and drip-line depths of drip systems on tomato yield, fruit quality and irrigation water use efficiency （IWUE）. The results showed that tomato yield and IWUE increased, soluble sugar and water-soluble acid of tomato fruits were improved in a certain degree, and Vc changed hardly as well as soluble solids under reclaimed water irrigation. Shorter irrigation interval and deeper drip-line depth would increase IWUE and yield. There were good effects of water-saving and improving yield under reclaimed water drip irrigation with shorter irrigation interval and deeper drip-line depths.
