1 麦棉两熟大套行的发展鲁西南地区既是棉产区,也是粮产区。80年代初试行麦棉耕作制度,至90年代初两熟面积占到棉田总面积的近80%,基本解决了粮棉争地矛盾。但是,在麦棉两熟的迅速发展中,也一直存在着晚发晚熟、棉花产量低而不稳、原棉品质差的问题。为有效地解决这一问题,荷?
The development of a large crop of double row of wheat and cotton The southwestern region is both a cotton producing area and a grain producing area. In the early 1980s, a trial of wheat-cotton farming system was carried out. By the early 1990s, the area of double-ripening accounts for nearly 80% of the total area of cotton fields, basically solving the conflict between grain and cotton.

In order to effectively solve this problem,
