展旦召治沙站位于库布其沙漠东部,鄂尔多斯高原北缘的黄河阶地上,属干草原地带。主风方向西北偏西风。沙丘类型是新月形沙丘链,丘间低地潜水位1—2米,低地土壤为非地带性浅色草甸土。多年来的生产实践证明,在流动沙丘上造乔木林必须用3—4年生、高4—6米的大苗,才能抵御风沙袭击,保证成活和生长。但在纵横交错的明沙梁上,运输大苗非常不便。我们在治理流沙中,摸索出在流沙腹地建立流动苗圃,达到了就地育苗,就地造林,减少了运输,降低了费用,促进了造林治沙工作的开展。现将流动苗圃育苗的方法简介如下:
Zhaizidang Shazhi station is located in the east of the Kubuqi desert, the Yellow River terraces in the northern edge of the Ordos Plateau, is a steppe steppe. Main wind direction northwest westerlies. Sand dune type is a crescent dune chain, dune 1-2 meters low groundwater, lowland soil as non-belt light meadow soil. Years of production practice has proved that the flowering sand dunes made of arbor forests must use 3-4 years old, 4-6 meters high seedlings in order to withstand the wind and sand attack to ensure survival and growth. However, the criss-cross Mingsha Liang, the transport of large seedlings is very inconvenient. In the management of quicksand, we explored the establishment of mobile nurseries in the fast-moving hinterland, achieving in situ nurseries, afforestation in situ, reducing transportation, reducing costs and promoting the work of afforestation and sand control. Now the method of nursery nursery mobile flow is as follows:
