我区东部平原是老产棉区,植棉历史较长,面积也大,历年种棉面积占总耕地面积的30％。以上,亩产皮棉65公斤以上。棉花是农民增加收入的主要经济作物,但多年来种植的都是有毒棉品种,即种子、枝叶中均含有大量对人富有毒的物质——棉酚和多种色素。能利用的仅是棉纤维和油脂,而这些又只占棉花生物学产量的15％左右。其85％的如棉籽饼、枝叶等都含有大量的蛋白质、纤维素和维生素等人畜所需要的营养物质,目前只能做肥料和烧柴,没有充分被利用。据测定,棉仁中蛋白质含量可达40％,棉籽壳含12％,吐絮后的干枝叶、茎秆平均含蛋白质7％左右(吐絮前的鲜枝叶为20％)。而小麦的蛋白质含量仅有12％左右。
The eastern plain of our region is an old cotton producing area with a long history of cotton planting and a large area of 30 years of total cotton area. Above, more than 65 kg of lint per mu. Cotton is a major cash crop for farmers to increase their income. However, cotton has been planted over many years, namely seeds, branches and leaves contain a large amount of toxic substances - gossypol and various pigments. Only cotton fibers and fats can be used, and these account for only about 15% of cotton’s biological yield. 85% of its nutrients such as cottonseed cake, branches and leaves contain large amounts of protein, cellulose and vitamins and other human and animal needs, at present only fertilizer and firewood, not fully utilized. It was determined that the protein content of cotton kernels up to 40% cotton seed hull containing 12% of the dry branches and leaves after bolting, stalks containing protein about 7% (spit flocculation of fresh leaves before and after 20%). The protein content of wheat is only about 12%.
