摘　　要：为筛选出适宜鄱阳湖植棉区油棉两熟轻简种植的最佳棉花品种,2020年选用了8个棉花品种进行了大田比较试验。结果表明,晶华棉116在10月中旬的吐絮率为85.98%,实收籽棉产量和理论皮棉产量均最高,分别为2262.6和1057.3 kg/hm^(2),其生育期较短,铃大、衣分高,成铃吐絮集中且适宜机采;赣杂棉0906生育期较长,铃大、衣分高,产量潜力大。因此,从产量的角度考虑,在油棉两熟制种植模式中,棉花油菜连作机播、机收适宜的棉花品种推荐晶华棉116,油后免耕直播,棉林套播油菜的适宜棉花品种推荐赣杂棉0906。In order to screen out the best cotton varieties suitable for double cropping of rape and cotton in Poyang Lake cotton planting area,eight cotton varieties were selected for field comparison test in 2020.The results showed that the boll opening rate of Jinghuamian 116 in mid-October was 85.98%,and the yield of paid-in seed cotton and theoretical lint were the highest,which were 2262.6 and 1057.3 kg/hm^(2).Its growth period was short,bolls were large,lint percentage was high,bolls opening were concentrated and it was suitable for machine picking.Ganzamian 0906 had relatively long growth period,large bolls,high lint percentage and great yield potential.Therefore,from the point of view of yield,in the rape-cotton double cropping system,the suitable cotton variety for continuous cropping of cotton and rape was Jinghuamian 116,and the suitable cotton variety for interplanting rape in cotton forest was Ganzamian 0906.
