摘　　要：以转基因抗病虫早熟棉品种邯686为试验材料，在田间设置4个不同播期处理，研究了洋葱茬后直播早熟棉的种植效果，结果表明：以5月31日播种的籽棉产量最高，为4044.0 kg/hm^2，5月26日播种次之，为3948.0 kg/hm^2，均比6月5日增产显著、6月10日增产极显著。因此，建议冀中南地区邯686洋葱茬后直播适宜播期是5月26～30日，最晚不应晚于6月5日。In order to study the effect of early maturing cotton （Han 686）planting after onion reaping,we set up four different sowing dates in the field trial by taking Han 686 as test material,And Han 686 is early maturing transgenic cotton va-riety that resistant to insect pests.The results showed that the yield of May 31 sowing treatment is the highest which is 4044.0 kg/hm^2;the yield of May 26 sowing treatment is the second which is 3948.0 kg/hm^2 and both of that is higher June 5 and June treatment significantly.The results also showed that the suitable sowing date of Han 686 in Hebei central and southern regions was between May 26 and May 30,and should not be later than June 5 at the latest.
