摘　　要：为确定新疆温室滴灌番茄适宜灌水量，在新疆农垦科学院科研基地开展田间小区试验，研究不同灌水量处理对温室滴灌番茄土壤水分状况、产量及品质的影响。结果表明，温室番茄土壤水分状况变化幅度随着生育期的推进呈现先增大而后缓慢减小的趋势，就灌水量的影响程度而言，灌水量较小的T1（3600m3／hm2）、T2（4200m3／hm2）处理仅对0～40cm土层土壤质量含水率影响较大，而灌水量较高的．r4（5400m3／hm2）与T3（4800m3／hm2）处理对0～60cm土层均有较大影响。番茄红素含量随灌水量的增大呈现减少趋势；可溶性糖含量总体变化趋势为随灌水量增大先减小而后增大，之后再减小；维生素c、可溶性蛋白含量以T2最高。番茄产量在一定范围内随着灌水量的增大而增大，但是达到一定程度后出现减少趋势。建议新疆温室滴灌番茄灌水量为4800m3／hm2。To determine the appropriate irrigation amount of tomato in greenhouse in Xinjiang,the field experiment was conducted to study the effects of different irrigation amount treatments on soil moisture, yield and quality of tomato in the research base of Xinjiang Academy of Agricultural and Reclamation Science. The results showed that soil moisture of tomato in greenhouse firstly increased and then decreased slowly with the advance of growth period. The high amount of irrigation of T4 and T3 treatments had greater im- pact on the soil moisture in depth of 0--60 cm,while T1 and T2 treatments only had greater impact on the soil moisture in depth of 0--40 cm. With the increase of irrigation amount, the lycopene content de- creased, and the content of total sugar overall first increased and then decreased, at last decreased. The contents of vitamin C and protein of T2 treatment were the highest. The yield of tomato in greenhouse in- creased with the increase of irrigation amount in a certain range, hut reduced when it was up to a limit. The recommended irrigation amount was 4 800 m3/ha for tomato in greenhouse in Xinjiang.
