摘　　要：采用裂区设计,调查了冀南棉区棉花的生育期、"三桃"比例、霜前花率以及霜前皮棉产量,分析了棉花早熟品种、中早熟品种和中熟品种在冀南棉区的适应性。结果表明:在冀南棉区不适宜种植早熟品种,中熟品种的适应性好于中早熟品种。该区可试种中晚熟品种,以求获得更高产量。The growth period,ratio of pre-hot summer boll,hot summer boll and autumn boll,rate of blossom before frost,and pre-frost lint cotton yield were investigated by the split plot design in south Hebei Province.The adaptability of early maturing variety,mid-early maturing variety and middle maturing variety was analyzed.The results showed that the early maturing variety was not suitable,and the adaptability of middle maturing variety was better than that of mid-early-maturing variety.Higher yield would be obtained by trial planting of mid-late maturing variety.
