北京地区小型西瓜日光温室栽培品种比较试验

摘要

This paper carried on the comparative experiment on six varieties of small fruit watermelon in sunlight greenhouse in Beijing region. The results showed that disease resistances and tolerance performance of six watermelon varieties were good.The comprehensive properties of Jingying 6-2 and Jinxiu were the best,which were suitable for sunlight greenhouse cultivation and promotion in Beijing.Jingying 6-2 was early-mid maturity and hard fruit variety,which had the highest fruit weight(1.84 kg)and yield(53 876.67 kg/hm2),It had the second place of sugar content(13.0%);Jinxiu was early-maturing and hard fruit variety,which had the third sugar content(12.7%)and the second place of fruit weight(1.78 kg)and yield(52 386.67 kg/hm2);The fruit quality of Mengxiang-10 was excellent,which had the highest sugar content(13.7%).it was late-maturing and hard fruit variety.The advantages of fruit quality included more fruit juices,refreshing sweet,less fiber,etc .Although the rest of the varieties had own characteristics,for the reason of the long fruit growth period long,poor crack resistance,low sugar content etc,were not suitable for spring greenhouse planting in the Beijing area.%在北京地区日光温室中进行6个小型西瓜品种比较试验。结果表明：6个西瓜品种在抗病性和抗逆性方面均表现良好。京颖6-2和锦绣的综合性状表现良好，适宜在北京地区日光温室设施类型种植推广。其中，京颖6-2属于中早熟脆肉类型品种，单果重、产量均居第1位，分别为1.84 kg、53876.67 kg/hm2，中心可溶性固形物的含量居第2位（13.0%）；锦绣属于早熟脆肉类型品种，其中心可溶性固形物的含量居第3位（12.7%），单果重和产量居第2位，分别为1.78 kg、52386.67 kg/hm2。其次是梦想10号，该品种属晚熟脆肉类型品种，品质性状突出，汁液含量最多，味甜爽口，中心可溶性固形物的含量达13.7%，居各品种首位。其余品种虽各具特色，但因耐裂性差、果实生育期偏长、中心可溶性固形物低等原因，不太适宜种植在北京地区日光温室。
