摘要:
选用 10 种基质类型栽培美丽异木棉（Chorisia speciosa），并施用不同种类和质量肥料，比较 不同基质和肥料对美丽异木棉开花植株和花形态结构的生长影响，进而筛选出适合美丽异木棉促花栽培 营养基质和肥料类型。结果表明：不同基质处理对美丽异木棉抽梢长和嫁接口直径生长存在显著差异， 不同种类和质量肥料对美丽异木棉生长、花期、花形态结构等存在差异，处理 G4( 塘坭 + 黄金生物植料 ) 的抽梢长和嫁接口直径生长最好，且开花株数最多，花长、花径、花瓣长和花瓣宽等形态指标比上一年 度增大。施钙镁磷肥可提早花期 ; 施花多多 2 号肥可使花长、花径、花瓣长和花瓣宽等形态指标增大。

Abstract:
10 different kinds of substrate were used to cultivate Chorisia speciosa and different types and quality fertilizers were applied to compare the growth effects of flower morphological structures by different substrates and fertilizers, in order to screen the suitable nutrient substrate and fertilize formula. The results showed that different substrate types affected the shoots and graft interface diameter growth and fertilizers had significantly affected, flowering time and flower morphological structures. The seedling shoots and graft interface diameter growth were the best by treated with G4 (pond scum + Gold bio-fertilizer), the number of flowering plants was also the highest. The morphological index such as flower length, flower diameter , petal length and petal width increased compared with the previous year. The application of calcium, magnesium and phosphorus fertilizers can be early flowering. The application of Peters fertilizer can increase flower length, flower diameter, petal length and petal width.
Key words:  promote flower cultivation  substrate formulation  fertilizer  flowering time  flower morphology  Chorisia speciosa
