低酚棉不仅棉纤维具有较高的经济价值,更主要的是副产品的综合利用程度高。常规棉种因含有较高的棉酚,对人、畜有毒害;占棉株87％的棉叶、茎和棉饼虽含有丰富的蛋白质,但不能经济有效地被利用。低酚棉是通过育种手段,消除了棉毒素有害物质,其棉仁可直接做高级食品和饲料,棉叶、棉秆可做牲畜的高蛋白饲料。而且,棉仁蛋白质含量和脂肪含量比常规棉高,含维生素和氨基酸亦较齐全。因此,低酚棉是今后棉花的发展方向。我国1987年种植低酚棉面积已达50万亩,随着综合利用的发展,预计种植面积将急剧上升。
Low-phenol cotton not only has high economic value of cotton fiber, but more importantly, the comprehensive utilization of by-products is high. Conventional cotton seed because of high gossypol, toxic to humans and animals; cotton leaves accounted for 87% of the cotton, stem and cotton cake although rich in protein, but can not be used economically and effectively. Low-phenolic cotton is breeding means to eliminate harmful substances of cotton toxins, cotton kernels can be directly made of high-grade food and feed, cotton, cotton stalks can be used as livestock high protein feed. Moreover, the cotton protein content and fat content than conventional cotton high, with vitamins and amino acids are also more complete. Therefore, low-phenol cotton is the future direction of development of cotton. In 1987, China planted 500,000 mu of low-phenol cotton. With the development of comprehensive utilization, the acreage of planting is expected to rise sharply.
