2017年全國棉花播種面積為3229.6千公頃(4844.5萬畝)，比2016年減少146.6千公頃(219.9萬畝)，下降4.3%。分地區(qū)看，我國最大的產棉區(qū)新疆棉花播種面積比2016年增加8.7%；其他棉區(qū)受種植效益低和種植結構調整等因素影響延續(xù)了減少較多的趨勢，其中黃河流域棉區(qū)下降24.3%，長江流域棉區(qū)下降14.9%。
盡管種植面積有所減少，但全國棉花單產有所提高。2017年全國棉花每公頃單位面積產量為1698.6公斤，比上年增加116.1公斤，增長7.3%。新疆棉區(qū)由于小散種植戶減少，規(guī)模種植面積增加等因素影響，每公頃棉花產量增長4.4%；黃河流域棉區(qū)每公頃單位面積產量增長2.1%；長江流域棉區(qū)每公頃單位面積產量下降3.6%。
