河西走廊为甘肃省主要农垦区,土地辽阔,拥有大片待开垦的草原和荒地,是建设和发展社会主义机械化农业的美好基地。水利建设蓬勃发展,灌溉面积日益扩大,目前已建成之国营农场已是数十个,特别是关外玉门,安西等垦区,国营农场群的出现是指日可望。 河西走廊,由于土壤母质含盐以及地域,气候等关系。土壤可溶性盐多,其中硫酸盐、氯化物、碳酸盐,重碳酸盐都有,在盐类的组成上,以硫酸盐为主,就盐份的分布,冲积扇上部较轻,冲积扇下部土壤粘重,透水性不良,盐份亦重。土壤质地之分布,亦属如此,扇形地上部土壤质地为轻,而下部质地偏重。根据盐份的组成,以硫酸盐为主,本区为氯化物 The Hexi Corridor is a major agricultural reclamation area in Gansu Province. With vast land and large areas of grassland and wasteland to be reclaimed, it is a beautiful base for building and developing socialist mechanized agriculture. Water conservancy construction is booming and irrigation area is expanding day by day. At present, dozens of state-owned farms have been built up, especially in Yumen and Anxi areas outside Guanzhong. The emergence of state-owned farms is expected. Hexi Corridor, due to the soil salt and the parent material, climate and other relations. Soil soluble salts, of which sulfate, chloride, carbonate, bicarbonate have, in the composition of the salt, mainly sulfate, salt distribution, alluvial fan upper light alluvial fan Lower soil sticky, poor water permeability, salt is also heavy. The same is true of the distribution of soil texture, light soil texture of the fan above ground, while the lower texture is heavy. According to the composition of the salt, mainly sulfate, this area is chloride
