soil seed bank

The advance and prospect of soil seed bank in the alpine grassland

高寒草地土壤种子库研究进展及展望

Soil seed bank density in sunny slope was 2.2-3.4 times than that in shady slope.

阳坡的土壤种子库密度为阴坡的2.2~3.4倍；

The soil seed bank and vegetation are similar in terms of species composition, density, the indices of the diversity and similarities.

土壤种子库和地上植被在物种组成、密度、生物多样性以及相似性系数方面均具有较高的相似性。

Soil seed bank number have a significant increased in Caragana plantation.

种植人工柠条林对土壤种子库具有显著富集种子的作用。

It is found out through the study on soil seed bank of Seabuckthorn community and standing vegetation that along with the increase of secondary reclamation time of sample lands, the increasing trend of index of diversity of species is decreased.

但是通过对沙棘群落土壤种子库和地上植被的研究发现，随着样地复垦时间的增加，其物种多样性指数的提高趋势下降。

The number of germinable seeds per soil sample ranged from 45 to 305 with an average of 102. Seeds of perennial grasses, perennial forbs and annuals accounted for 46 57, 51 96 and 1 47 percent of the total seed bank, respectively.

每样中的可萌发种子量变化于45到305之间，平均102/样。多年生禾草、多年生杂类草及1年生植物的土壤中种子量分别占总可萌发种子库的46.57%、51.96%和1.57%。
