六盘山冷凉区不同花椰菜品种比较试验

Comparative Trail on Different Cultivars of Cauliflower in the Cold Areas of the Liupan Mountains

为了筛选出适宜宁夏六盘山冷凉区种植的花椰菜品种,引进了6个花椰菜品种开展品比试验,比较分析了不同品种的生育期、株高、叶片数、冠幅、产量及品质等指标。结果表明:津松75、津松69、新贵松花65天和新贵70天的生育期比春秀和改良绿芯青花菜生育期短;6个花椰菜品种在采收期的株高、叶片数和冠幅相差不大;春秀、津松75与津松69的产量均较高,改良绿芯青花菜产量较低;津松75、津松69、新贵松花65天、新贵70天和改良绿芯青花菜的蛋白质、可溶性糖、粗纤维和VC含量均显著高于白菜花品种春秀,营养价值较高。综合品种各方面的表现,结合市场发展前景,松花菜品种津松69和津松75更适宜在六盘山冷凉区推广种植。

In order to screen out cauliflower cultivars suitable for cultivation in the cold areas of the Liupan Mountains located in Ningxia, 6 cauliflower cultivars were introduced in the comparative trail, and the indexes of different cultivars including growth period, plant height, leaf number, crown width, yield and quality were compared and analyzed. The results showed that the growth periods of ＇Jinsong 75＇, ＇Jinsong 69＇, ＇Xinguisonghua 65 days＇ and ＇Xingui 70 days＇ were shorter than ＇Chunxiu＇ and ＇Gailiangliixin＇; the plant height, leaf number and crown width of 6 cauliflower cultivars showed little differences in the harvest period; the yields of ＇Chunxiu＇, ＇Jinsong 75＇ and ＇Jinsong 69＇ were higher, and the yield of ＇Gailiangltixin＇ was lower; the contents of protein, soluble sugar, crude fiber and VC in ＇Jinsong 75＇, ＇Jinsong 69＇, ＇Xinguisonghua 65 days＇, ＇Xingui 70 days＇ and ＇Gailiangltixin＇ were significantly higher than white cauliflower cultivar ＇Chunxiu＇, which reflected their higher nutritional value. In consideration of the performances of all cultivars in various aspects, combined with the development prospects of the market, ＇Jinsong 69＇ and ＇Jinsong 75＇ were more suitable to be planted in the cold areas of the Liupan Mountains.
