單產(chǎn)高，品質(zhì)高，主要與今年河北天氣有直接關(guān)系。在棉花生長期，天氣表現(xiàn)為兩頭雨水正常，中間伏旱，部分棉田早衰。今年河北棉花在4月播種，生長期蟲害輕，蚜蟲發(fā)生期蚜蟲幾乎沒有出現(xiàn)。伏桃多，主要6月雨水充足，遇到伏旱秋桃少。今年棉花吐絮早，9月底吐絮已到頂，較去年吐絮提前有一個多月，基本沒有出現(xiàn)陰雨天氣，所以品質(zhì)好。
面積產(chǎn)量方面，現(xiàn)在國家統(tǒng)計局河北調(diào)查隊的面積是616萬畝，比去年減少108萬畝。單產(chǎn)是71.76公斤，比去年增8公斤多。單產(chǎn)與今年500斤/畝籽棉相比存在較大差距。
