<正>就5种栽培密度和7种无土复合基质对微型月季个体和群体生长发育的影响进行了研究。对叶面积、单株生物量、群体生物量等的测定结果表明,栽培密度1(每盆栽1株)最有利于微型月季的个体发育,密度5(每盆栽5株)最有利于盆花群体的发育;基质处理3(70%泥炭+30%珍珠岩)和处理6(70%珍珠岩+30%泥炭)最有利于微型月季个体和群体的生长发育;微型月季株高和花朵大小受各种处理影响较小。在盆花生产中,应采用较大的栽培密度和最佳的复合基质,注重盆花群体的生长发育,以提高其商品观赏性和经济效益。

The effects of different planting densities and growing media on the growth and development of miniature pot rose(Rosa hybrida ’Miniature Pink’) were studied in this paper.The results showed as follows:With characters of root number,the fresh and dry weight of roots,area of leaves,the fresh and dry weight of shoots and the whole plant,the first planting density(1 plant per pot) created the greatest effects on the individual plant,while the fifth(5 plants per pot) had the greatest effects on the pot flower colonies(pot flower);Two kinds of growing media(70% peat moss+30% pearlite and 70% pearlite+30% peat moss)could promote growth of miniature rose most significantly;All the treatments had no significant effects on plant height and diameters of flowers. In production practice,it is better to culture more plants per pot for promoting rapider growth and development of miniature rose colony.
