摘要
【目的】筛选适宜海南陵水设施无土栽培的小型耐裂精品西瓜品种,以满足人们对高品质西瓜的需求,促进海南设施西瓜产业发展。【方法】在陵水设施大棚内,以纯椰糠为栽培基质,采用营养液滴灌立体吊蔓栽培方式,以美月为对照种,对21个西瓜品种进行了产量、果实性状及品质性状比较与分析。【结果】供试西瓜品种单果重介于1.35~2.05 kg,每667 m^2产量为1799.4~2727.3 kg,其中单果重和产量最高的是L600;中部可溶性固形物含量变化为9.9%~12.9%,其中琼香最高;西瓜可溶性糖以果糖为主,其次为葡萄糖,可溶性糖含量介于54.94~87.65 mg/g,其中热研墨玉最高;糖酸比变化范围为20.22~53.41,其中万福来最高;果皮硬度变化范围为32.56~69.41 kg/cm^2,显著高于对照种美月的品种有锦绣前程、艳玲、金镶玉、美蓉、琼美、全美2K、全美4K、4126、3416、L600;根据平均隶属函数值进行综合评价,L600排名第一,其次为锦绣前程。【结论】综合产量、品质及果皮特性指标,筛选出品质优良且耐裂果的L600和锦锈前程为适宜海南陵水设施无土栽培的小型西瓜品种。
【Objective】The aim of this study was to screen out crack resistant and high-quality miniwatermelons under soilless cultivation in Lingshui of Hainan,which could meet people's demand for high-quality watermelons and promote the development of Hainan facility watermelon industry.【Method】In the greenhouses of Lingshui,all watermelons were planted by three-dimensional creeper cultivation method with pure coconut dust as cultivation matrix and nutrient liquid drip irrigation.With Meiyue as the control variety,the yield,fruit characters and quality characters of 21 watermelon varieties were compared and analyzed.【Result】Among all the watermelon varieties tested,the single fruit weight varied from 1.35 to 2.05 kg,and the yield varied from 1799.4 to 2727.3 kg per 667 m^2,among which L600 had the highest single fruit weight and yield.The soluble solid content in the center varied from 9.9%to 12.9%,and that of Qiongxiang was the highest.The soluble sugar of watermelon was mainly fructose,followed by glucose,and the soluble sugar content was 54.94-87.65 mg/g,among which Reyanmoyu was the highest.The sugar-acid ratio ranged from 20.22 to 53.41,among which Wanfulai was the highest.The range of rind hardness was 32.56-69.41 kg/cm^2,and the rind hardness of the 10 varieties(Jinxiuqiancheng,Yanling,Jinxiangyu,Meirong,Qiongmei,Quanmei 2K,Quanmei 4K,4126,3416,L600)was significantly higher than that of Meiyue.Based on the average membership function values,the L600 ranked first,followed by the Jinxiuqiancheng【.Conclusion】Based on the comprehensive evaluation on indicators of yield,quality and pericarp characteristics,L600 and Jinxiuqiancheng with good quality and crack resistant were selected as watermelon varieties suitable for soilless cultivation in greenhouses in Lingshui of Hainan province.
