为筛选适合北京地区种植的无籽西瓜,满足市场需求,引导生产者选择种植优良的中果型无籽西瓜品种,开展新品种筛选试验研究。本研究在田间条件下,选择了京欣1号和日本SL-BL19为试验材料,以传统品种暑宝作对照进行筛选,记录作物在生长期间的长势相关数据,对果实的品质和产量进行了对比分析。结果表明:种子出芽率最高的为日本SL-BL19,达到83.30%,京欣1号为80.60%,暑宝出芽率最低为72.90%。京欣1号667m2产量最高,为4880.21kg,日本SL-BL19667m2产量为4587.85kg,暑宝最低667m2产量为4459.47kg。日本SL-BL19中心可溶性固形物含量最高为11.37%,京欣1号为11.30%,暑宝最低为11.12%。综合考虑667m2产量和中心可溶性固形物含量等指标,日本SL-BL19和京欣1号表现均优于对照暑宝,建议北京市大兴区瓜农优先选用中果型无籽西瓜日本SL-BL19和京欣1号品种进行种植。
In order to screen seedless watermelons suitable for planting in Beijing and meet the market demand, producers are encouraged to choose good medium-sized seedless watermelon cultivars to carry out screening research on new varieties. In this study, we selected Jingxin 1 and Japan SL-BL19 as experimental materials under the field conditions, screened the traditional varieties of summer treasure, recorded the growth of crops during the growth of the relevant data, the quality and yield of the fruit Comparative analysis. The results showed that the seed germination rate was the highest in Japan SL-BL19, reaching 83.30%, Jingxin 1 was 80.60%, and the lowest in Shu-Po was 72.90%. Jingxin 1 667m2 highest yield, 4880.21kg, Japan SL-BL19667m2 yield of 4587.85kg, Solstice minimum 667m2 yield of 4459.47kg. Japan SL-BL19 center soluble solids content of the highest 11.37%, Beijing Xinxin 11.30%, Solstice minimum 11.12%. Comprehensive consideration of 667m2 yield and soluble solids content of the center and other indicators of Japan SL-BL19 and Beijing Xin 1 performance are better than the control Shu-Po, Gansu farmers in Beijing Daxing preferred to give priority to the fruit-type seedless watermelon Japan SL-BL19 and Beijing Xin 1 varieties for planting.
