南疆地区朱顶红引种驯化适应性研究

Adaptability of Hippeastrum hybridum of Introduction and Domestication in Southern Xinjiang Region

以朱顶红双龙品种为供试材料,设置拌施20%有机土壤改良剂、拌施2%石膏粉2个土壤处理,以南疆地区原生土为对照处理,测定土壤pH、生长指标(株高、株宽等)和繁殖指标(分蘖率、花茎率)。结果表明,土壤改良剂显著降低土壤pH值,施用20%有机土壤改良剂能将原生土从碱性改良为中性。施用有机土壤改良剂能显著提高朱顶红球径、株高、株宽、最长叶片长、最长叶片宽等生长指标,促进朱顶红花茎的产生,有利于提高朱顶红观赏性;对照处理朱顶红各生长指标显著低于其他2个处理,但分蘖率显著高于其他2个处理,说明种植在南疆地区原生土壤中促进了朱顶红无性繁殖。

Taking Hippeastrum hybridum variety Double Dragon as material,setting two soil treatments of mixing 20%organic soil amendments(T1),2%gypsum powder(T2),native soil in southern Xinjiang area as the control,pH value of soil,growth indexes such as plant height and plant width index,reproductive indexes such as the tillering rate and stem rate were determined.The results showed that soil ameliorant could significantly reduce the pH value of soil,and the application of 20%organic soil ameliorant could improve the primary soil from alkaline to neutral.The application of organic soil amendments could significantly increase plant height,width,the length and width of the longest leaf of Hippeastrum hybridum,promote the production of flowers and stems,which was beneficial to its ornamental quality,and the growth indexes of the control were significantly lower than those of the other two treatments,but its tiller rate was significantly higher than the other two treatments,which indicated that planting of Hippeastrum hybridum variety Double Dragon in the southern Xinjiang native soil promoted its asexual propagation.
