摘　　要：观测研究了4种不同基质对小鸟花生长、切花产量及叶片组织结构、细胞超微结构的影响.结果表明:黄泥+泥炭作基质最理想,大田土次之,两者表现为叶片绿色,切花产量较高,叶肉细胞排列疏松,叶绿体多且发育正常;泥炭+黄泥+菇渣和黄泥+菇渣+沙作栽培基质的植株叶片有不同程度的失绿现象,叶肉细胞排列紧密,叶绿体遭到不同程度的破坏,切花产量受到影响,花质较差.The effects of four different culture medium on the growth, cut flower yields, leaf structure and ultramicroscopic structure of Heliconia psittacorum cells were studied. The results showed that the mixture of yellow soil and peat was the best medium, followed by the field soil. When grown in the two media, H. psittacorum produced green leaves and high yields of cut flowers. Also, the leaf cells were normally developed. However, the basic media, eg. the mixture of yellow soil and peat and mushroom compost or the mixture of yellow soil and mushroom compost and sand, inhibited the growth of plants. The leaves showed symptoms of chlorosis, the leaf cells were arranged densely, the chloroplasts were damaged to some extents. This resulted in low yields and poor quality of cut flowers.
