| 摘 要： | 试验以新疆大面积露地栽培种植的厚皮甜瓜品种金龙为试验材料,通过在甜瓜生长各个生育期设置不同的灌水下限,研究灌水下限指标对产量、水分利用效率、商品率和品质等的影响。结果表明:当苗期灌水下限为60%θf、开花坐果期75%θf,果实膨大期80%θf,成熟期65%θf时,甜瓜产量、水分生产效率和商品率均较高,且有利于增加单瓜重,提高可溶性固形物含量,其他各项品质指标也均在平均值以上。研究成果将为甜瓜露地膜下滴灌优质高产栽培灌溉制度的制定提供理论依据,为膜下滴灌技术在甜瓜露地栽培上应用和推广提供技术支撑。

| Abstract: | Using the muskmelon(Jin long),which has the big planting area in Xinjiang,as experiment material,the effects of different irrigation lower limit on the yield,the water use efficiency,the quality and the commodity rate are studied in this paper.The results show that when the irrigation lower limit are 60% of θf at the seedling periods,75% of θf at the flowering and fruit bearing periods,80% of θf at the fruit expanding periods and 65% of θf at the mature period,the yield,water use efficiency and the commodity rate are higher.The research results will provide the theory basis for establishing greater and better irrigation schedule and the technical support for the application of the drip irrigation under film. |
