摘　　要：在保证全生育期灌水量相等的前提下,研究微喷条件下不同灌溉频率对早春温室小果型西瓜生长特性和品质的影响。试验设3、5、7 d灌水1次和对照共4个处理。结果表明,5 d灌水1次的单果质量和667 m^(2)产量最好,分别为1.44 kg和3708.95 kg,并与其他3个处理存在显著性差异。在品质方面,3 d灌水1次的中心可溶性固形物含量最低,为12.17%,且与其他3个处理差异显著。这表明高频率灌溉不利于中心可溶性固形物的积累,不同灌溉频率对西瓜边部可溶性固形物积累和果皮厚度影响较小,各处理之间差异均不显著。综上所述,5 d灌水1次的频率更适合在大兴地区西瓜生产中进一步推广和应用。This experiment is to study the effect of different irrigation frequencies on the growth characteristics and quality of mini-watermelons in the greenhouse in early spring under micro-spray irrigation,ensuring an equal amount of water during the whole growth period.Four treatments were arranged in the experiment:T1,micro-spray irrigation once every 3 days,T2,once every 5 days,T3,once every 7 days,and T4,the control treatment.The T1,micro-spray irrigation,showed a significantly higher single fruit weight and yield per mu:1.44 kg and 3708.95 kg·667 m^(-2),respectively,as compared to other treatments,while the soluble solid content at the centre in T1 treatment was 12.17%,which was significantly lower than that of other treatments.In terms of the accumulation of soluble solids and the skin thickness,different irrigation frequencies posed little effect,without a significant difference;concerning the growth vigour of plants,T1 treatment was beneficial to the promotion of the growth of plant height up to 274.89 cm at maturity.In the control treatment,stem diameter grew better,7.93 mm at maturity.The morphological and agronomical indicators in this study:yield and quality data indicate that the T2 micro-spray irrigation once every 5 days is more suitable for watermelon production in Daxing area.
