据土壤普查资料统计,湖北全省有飞沙土低产地210余万亩,主要呈带状分布于江汉平原江河两岸,系历年江河泛滥的沙质沉积物所形成。飞沙地上的作物产量很低,粮食作物每亩产量只五、六十斤。如遇干旱年成或播种较迟、管理不及时,以致作物在旱季来临前尚未生长起足够的营养体或不能及早成熟,则甚至可能完全无收。改良飞沙土,提高粮、油作物产量,是改良湖北省1,400 According to the statistics of soil census, there are more than 210 mu of low-yielding earth-borne sandy areas in Hubei Province, mainly distributed in the rivers and streams along the Jianghan Plain. The production of the crop on the flying sand is very low. The output of grain crops is only five or sixty catties per mu. In the event of a drought, or later sowing, the management is not timely, so crops that have not grown enough to nourish or mature early before the onset of the dry season may not even be sold at all. Improve fly sand, improve grain, oil crop production, is to improve 1,400 Hubei Province
