They may be ejected from the plant onto the bare soil, or entangled on the dead mother plant. 它们可能由植株直接落到裸露的土壤上,或者连接在死亡的母株上。
Bare soil is protected from the impact of rainfall which can cause surface soil crusting, compaction, and erosion. 塑料薄膜覆盖使裸土免受降雨引起的表土结壳、压实和侵蚀。
In areas, such as flat loess plains, where the bare soil is covered with a massive crust, there are two main microhabitats in which seeds accumulate and germinate : soil cracks and furrows. 在平坦的黄土平原上,土壤被一层很厚的灰尘覆盖,种子聚集和萌发的微生境有两个:土壤碎块和犁沟。
