我国为世界主要产棉国之一。1984年全国棉花产量达12160万担,比1949年增加12.7倍,已自给有余,还可大量出口。纤维长度由解放初期的22毫米上升到27～29毫米。品级亦有提高。含杂、含水均有降低。但与进口美、苏棉相比,还有差距:主要表现强度低、断裂长度短及成熟度欠佳。这与现代棉纺工业对原棉品质的要求极不适应。
My country is one of the major cotton producing countries in the world. In 1984, the national cotton output reached 121.6 million, an increase of 12.7 times that of 1949. It has been self-sufficient and can be exported in large quantities. Fiber length from the early liberation of 22 mm rose to 27 ~ 29 mm. Quality also improved. Containing impurities, water are reduced. However, compared with the import of US and Soviet cotton, there are still gaps: the main performance of low strength, short length of rupture and poor maturity. This is incompatible with the requirements of the modern cotton spinning industry for the quality of raw cotton.
