The properties of prompt bloom experiment of different ornamental pineapple in Yinchuan

引进不同品种的观赏凤梨,在银川地区进行催花试验.针对不同生长发育时期对环境的要求,采取相应的养护措施,使其达到催花要求.催花结果表明:引种品种均可在预定时间内开花,在同种栽培基质、同一养护环境下,不同品种凤梨不同时期生长发育指标有明显差异.经乙炔气体催花后,不同品种观赏凤梨在株高、冠幅、叶片数、叶面积、花穗高度、花冠径等指标均有较大差异,以亮火炬表现最好,其次分别为亮紫星、黄星、吉利红星、丹尼斯星、彩苞莺歌、黄边莺歌.

This paper introduces several varieties of ornamental pineapple in Yinchuan and carries out prompt bloom date experiment. According to environmental requirement in different growth and developed periods, and prompt requirement, some management methods were applied in corresponding of growth and development. The result showed that it is possible that the introduced Ornamental Pineapple can blossom in Yinehuan by prompting bloom and there are different varieties of pineapple＇s growth indices showed obvious discrepancy in same matrix and surrounding.
