将采集的二十五种当地禾草成熟种子与消毒处理的7.5cm耕作土壤相拌合,并装入埋在土壤中的圆筒内。不久,多数禾草的种子均可萌发,但这些具有生活力的种子在耕作土壤中的持续性因种而异。约1/3的种(包括不实雀麦,大麦状雀麦,多年生黑麦草,燕麦草,草原看麦娘等)在初期萌发阶段过后,便极少再萌发。其它象丛生发草、绒毛草,粗茎早熟禾等被认为是草原土壤持久种子库(Seed bank)播后第二年也会大量萌发。具很强持续性的禾草有耕地杂草(野燕麦,早熟禾)及湿生禾草(折状甜茅,巨甜茅),它们在土壤耕翻后便可由贮存状态转入萌发。但某些种象早熟埃若禾,野燕麦、燕麦,仰卧扁芒草的种子萌发却有一定的季节规律,这可能与土壤中种子萌发生理要求周期变化有关。
Twenty-five native seeds of mature grass collected were mixed with sanitized 7.5 cm tillage soil and placed in a cylinder embedded in soil. Soon the seeds of most grasses can germinate, but the persistence of these viable seeds in cultivated soils varies from species to species. Approximately one third of the species (including false brome, barley-like barley, perennial ryegrass, oat grass, prairie maiden etc.) germinate rarely after the initial germination period. Others such as tufted grass, velvetleaf, bluegrass and so on are considered to be grassland soil seed bank (Seed bank) germination will be the second year after sowing. Grasses with strong persistence include arable land weeds (wild oats, bluegrass) and wet grass (Pinus taurica, giant sweet grass) that can be transferred from germination to germination once the soil is tilled over. However, the seed germination of some species such as Eruca, wild oats, oats and supine Miscanthus has certain seasonal patterns, which may be related to the periodic changes of physiological requirements of seed germination in soil.
