早熟黄皮洋葱新品种比较试验

Comparative Test on New Varieties of Precocious Onion with Yellow Skin

[目的]对早熟黄皮洋葱新品种进行比较试验。[方法]以洋葱品种喜伯和快星为对照,对连云港市农业科学院选育的早熟黄皮洋葱品种希望之星和阳春黄3号的熟性、性状、不同收获期鳞茎大小、产量等方面进行比较试验。[结果]早熟洋葱在倒伏后鳞茎继续膨大,倒伏后7~10 d后至终收期,鳞茎增加的重量占最终鳞茎重的15%~25%;阳春黄3号熟性最早,产量高于对照品种;希望之星熟性与对照相当,并且在不同收获期均表现产量优势明显。[结论]该研究为优良品种的推广奠定基础。

[ Objective] To carry out comparative test on new varieties of precocious onion with yellow skin. [ Method] With onion varietiesXibo and Kuaixing as the control, comparative test on the maturity, character,bulb size and yield of Xiwangzhixing and Yangchunhuang 3were carried out, which were breeded by Lianyungang Academy of Agricultural Sciences. [Result]The bulb of precocious onion continued to expand after lodging, and the bulb increased from 7 - 10 d ater lodging to the final harvesting date,which accounted for 15% -25% of the weight of the bulb. The maturity of Yangchunhuang 3 was the earliest,and the yield was higherto the controls in maturity,and had an obvious yield advantage in different harvesting dates. [ Conclusion] This research laid foundation forthe extension of high-quality varieties.
