摘　　要：采用地热线夜间加温研究了根区加温对‘天鹅绒’一品红生长发育和盆花品质的影响,结果表明根区加温加快一品红的发育进程,并显著提高盆花品质,使开花时的枝长、株高、花径、冠幅、苞片面积、商品率显著提高。日最低气温11.2℃、根区温度13.5℃及日最低气温12.5℃、根区温度12℃仍可保证100%的商品率。The effect of root-zone heating on growth, development and visual quality of ‘Velvet＇ poinsettia were studied with electric-heating wire. The results showed that root-zone heating increased the developmental speed and improved visual quality of poinsettia with longer shoot, higher plant, wider canopy and bloom size, greater area of bract; and more salable percentage. One hundred percent of salable pot flowers could be produced when minimal daily air and root-zone temperatures at 11.2℃ and 13.5℃ ,or 12.5℃ and 12℃ ,respectively.
