| 摘 要： | 为了研究ＣＯ２倍增对实生苗羊草和移栽羊草的影响，采用开顶式熏气装置进行了ＣＯ２倍增试验。结果表明：２种羊草的ＣＯ２倍增与对照相比，年生长期延长２～７ｄ，其中枯黄期延迟１～７ｄ。ＣＯ２倍增的羊草分蘖株数、成熟穗数、生物量分别为对照的１１９．２％～１４６．３％、１３３．３％～１５７％、１１３．２％～１２７．３％；羊草植株高生长明显增加。ＣＯ２倍增对实生苗羊草物候期的反应比移栽羊草更敏感，移栽羊草抽穗数

| Abstract: | The effect of doubled CO2 concentration on the seedlings and transplanted seedlings of Leymus chinensis were examined by Opentop Chamber in this study. Compared with ck, the experiments showed that the growth period per year prolonged 27d, in which the wither period prolonged 17d, other phenological phases were 17d earlier than expected, the number of tillering and matured ears, biomass are respectively as 1192%1463%,1333%1571%and 1132%1273% as ck, the increase of height was distinct, too. Seedlings were more sensitive in phenological response to doubled CO2 concentration than the transplanted seedlings. While the number of increased tillering are less distinct. The effect of doubled CO2 concentration on phenological phases and growth are both positive. |
