用－３０℃、－１０℃、５℃和室内２０～２８℃（对照）对草地早熟禾、紫羊茅、高羊茅、剪股颖四种草坪草种子保存２００ｄ后分析得出，各草坪草种子要求冷藏温度不一样，恰当的低温保存可以保持原种子活力。草地早熟禾和剪股颖种子在－３０℃～－１０℃保存为好，紫羊茅以－３０℃为佳，而高羊茅在２００ｄ内无需冷藏。 The results showed that after the seeds of four turfgrasses were stored at -30 ℃, -10 ℃, 5 ℃ and indoor 20 ~ 28 ℃ (control) for 200d, the turfgrass, fescue, tall fescue, Grass seeds require refrigeration temperature is not the same, the appropriate low-temperature preservation can maintain the original seed vitality. Poa pratensis and Prunus pumila seeds were preserved at -30 ℃ ~ -10 ℃, while red fescue at -30 ℃ was better, while the tall fescue did not need to be refrigerated within 200d.
