为筛选出适合大兴地区种植的小果型黄瓤西瓜,选用目前市场上常见的小果型黄瓤西瓜进行品种对比试验。试验结果表明:京阑植株生长最旺,株高、茎粗和叶面积分别达到305.14cm、12.56mm和536.67cm2。羞月株高最高为339.72cm,但其叶面积和茎粗仅为472.33cm2和11.90mm,植株生长不平衡。3个品种中羞月茎粗最小,对照黄小帅茎粗最大,达到12.73mm。京阑商品瓜产量最高为5105.10kg/667m2,羞月最低为4139.30kg/667m2,畸形果率3个品种均较低,商品瓜产量间差异不显著。果实品质3个品种口感均为酥脆,京阑纤维含量居中,其他2个品种纤维量少。中心可溶性固形物羞月最高为11.34%,京阑最低10.84%;边缘可溶性固形物含量羞月最高为8.67%,黄小帅最低为7.82%。其中,黄小帅中心和边缘可溶性固形物含量梯度较大。总体比较,京阑在生长势、商品瓜产量以及果实品质方面均优于黄小帅,适合大面积推广种植;羞月虽然形状美观、品质极佳,但其与对照组之间产量差距较大,仍需进一步试验证实,建议以观光采摘和礼品销售为主的农户可以适量种植。
In order to select the small fruit-type water chestnuts suitable for cultivation in Daxing area, the small-fruit type water chestnut watermelon commonly used on the market was selected to carry out comparative experiments. The results showed that the plant grows best, the plant height, stem diameter and leaf area reach 305.14cm, 12.56mm and 536.67cm2 respectively. The highest height of the shy month was 339.72 cm, but its leaf area and stem diameter were only 472.33 cm 2 and 11.90 mm. The plant growth was unbalanced. Shame month 3 stems in the smallest stem diameter, control Huang Xiaoshuai largest stem diameter, reaching 12.73mm. The highest yield of Jingluan commercial melon was 5105.10kg / 667m2, the lowest was 4139.30kg / 667m2, the rate of deformed fruit was lower and the difference between commercial melon production was not significant. Three varieties of fruit quality are crisp taste, Jing Lan fiber content is medium, the other two varieties less fiber. The highest soluble solids content was 11.34% in sham months and the lowest in Jingxiao was 10.84%. The highest soluble solids content was 8.67% in shame month and 7.82% in Huang Xiaoshuai. Among them, Huang Xiaoshuai center and the edge of the soluble solids content gradient. In general, Jinglao is superior to Huang Xiaoshuai in growing potential, yield of melon and fruit quality, which is suitable for large-scale popularization and cultivation. Despite its beautiful shape and excellent quality, the shame-month has a large output gap with the control group. Further tests confirm that it is suggested that farmers who mainly focus on sightseeing picking and gift sales can plant properly.
