不同基质配方对鸡冠花生长和观赏品质的影响

Influence of Different Substrate Formula on Growth and Ornamental Quality of Cockscomb

以腐熟中药渣、腐熟菇渣、泥炭、珍珠岩和泥土为原料,按照不同比例复配成5种栽培基质,以泥土作为对照,研究了不同配比的栽培基质对2种鸡冠花生长和观赏品质的影响。结果表明:基质1和基质2中栽培的鸡冠花在株高、茎粗和花序长度等12个性状指标上均显著优于其它栽培基质。矮生头状鸡冠花在腐熟中药渣配比较低的基质1中的生长和观赏性最佳;植株高的羽状鸡冠花在腐熟中药渣配比较高的基质2中的生长和观赏性最佳。主成分分析和聚类分析结果表明,基质1和基质2可分别作为头状鸡冠花和羽状鸡冠花栽培的专用基质。

Taking decomposed Chinese traditional medicine residue,decomposed mushroom residue,peat coal,pearlstone and soil（the control） as the basic substrate,the author prepared 5 kinds of mixed substrates with different proportions of basic substrate,and investigated the effects of various mixed substrates on the growth and ornamental quality of two cockscomb species.The results showed that the 12 characters（plant height,stem diameter,inflorescence length,etc.） of cockscomb plants cultivated in substrate 1 and substrate 2 were significantly better than those of cockscomb plants cultivated in other substrates.The dwarf plants of Celosia cvisstata cultivated in substrate 1 with lower proportion of decomposed Chinese traditional medicine residue grew best and possessed the best ornamental quality,while the high plants of Celosia plumosa cultivated in substrate 2 with higher proportion of decomposed Chinese traditional medicine residue grew best and had the best ornamental quality.The results of principal component analysis and cluster analysis indicated that the substrate 1 and substrate 2 could be used as the special culture substrate of C.cvisstata and C.plumosa,respectively.
