棉田种植啤酒大麦,可不占粮田面积,不影响粮食生产,提供啤酒原料,支援啤酒工业,满足人民生活需要。啤酒大麦较小麦耐迟播,早熟、生育期短,可以缓和麦棉相互接茬在时间上的矛盾,但棉花腾茬晚,往往影响大麦播种过迟,仍会影响产量。对迟播大麦,实行地膜覆盖,揭下的地膜用来再盖棉花,麦、棉一膜两用,能防止大麦越冬冻害,促使大麦和棉花早发、高产、优质。 Planting of barley in barley does not occupy the area of ​​grain fields, does not affect food production, provides beer raw materials, supports the beer industry and meets the needs of people’s lives. Compared with wheat, wheat barley is more resistant to sowing, early maturing and shorter growth period. It can alleviate the time-consuming contradiction between wheat and cotton. But late tillage of cotton often affects the sowing of barley and will still affect the yield. For late-sowing barley, the mulching is carried out and the mulching film removed is used to cover the cotton, wheat and cotton in one film and dual-purpose film, which can prevent overwinter frost damage of barley and promote the early onset, high yield and high quality of barley and cotton.
