湖北新洲县是棉麦两熟产区。几年来,获得了小麦的持续增产。1964年全县34.1万亩小麦平均单产221斤,其中2.46万亩小麦,平均单产301斤。 为了探索棉麦两熟条件下小麦丰产的规律性,克服棉麦两熟在时间、空间和田间管理等方面存在的矛盾,我们于1959—1964年 Xinzhou County, Hubei Province, cotton and wheat are two mature producing areas. Over the past few years, continued to increase wheat yield. In 1964 the county 341000 acres of wheat average yield of 221 pounds, of which 24600 acres of wheat, the average yield of 301 pounds. In order to explore the regularity of wheat yield under wheat-wheat two-cropping conditions and to overcome the contradiction between cotton and wheat double ripening in time, space and field management, we found that in 1959-1964
