棉花是我国最主要的经济作物,棉花总产量居世界第一位。过去种棉花,大家只注意产多少斤皮棉,只重视棉花纤维的经济收益。实际上,棉花全身都是宝,除棉纤维是纺织工业原料外,棉花的副产品像棉短绒、棉籽壳、棉籽油、棉籽饼、棉秆、棉根皮等,都有重要的经济利用价值。过去大部分副产物只做了低级的粗放的利用,有些甚至废弃,造成资源的浪费,十分可惜。 Cotton is the most important economic crop in China with the total output of cotton ranking the first in the world. The past, cotton, we only pay attention to how many pounds of lint, only pay attention to the economic benefits of cotton fiber. In fact, the whole body is a treasure of cotton, except that cotton fiber is a raw material for the textile industry. Cotton by-products such as cotton linters, cotton seed hulls, cottonseed oil, cottonseed cake, cotton stalks and cotton root bark all have important economic value . In the past, most of the by-products were only used at a low level and extensively used. Some were even discarded, resulting in a waste of resources. It is a pity.
