一、无酚棉育种意义与动态人们种植棉花的目的是生产棉纤维,用来纺纱织布,但这仅是利用棉株体的一部分。一亩土地能收获350—400斤籽棉,而在100斤籽棉中,皮棉(即棉纤维)只占36—41％,约有60％是棉籽。棉籽仁中富含蛋白质和油脂。由于棉籽中有一种具有毒素的棉酚物质,单胃动物不能食用。榨油厂在获得优质棉籽油时,需进行精炼漂白,从而增加了工序,并提高了成本。 First, the significance and dynamics of cotton-free breeding Breeding cotton purpose is to produce cotton fiber, used to spin weaving, but this is only part of the use of cotton plant. One acre of land can harvest 350-400 pounds of seed cotton, while in 100 pounds of seed cotton, lint (ie cotton fiber) only 36-41%, about 60% is cottonseed. Cottonseed kernels are rich in protein and fat. Monogastric animals can not be eaten because there is a toxins material in cottonseeds. Oil mills get refined cotton blends when they get quality cottonseed oil, which increases the number of processes and increases their costs.
