摘要
对棉花水浮育苗的种子处理、播种日期与播种深度等育苗技术进行了研究,结果表明,芽长达到1/2种子长的种子播种出苗和棉苗素质最佳,并且得出棉花水浮育苗的安全播种日期为4月20日以后,播种深度1.5 cm左右为最佳。
Seed treatment, sowing-date and sowing-depth of float raising cotton seeding technology in tray water bed were studied. Results were as follows：（ 1 ）the best bud＇s length should be about half of the seed＇s length;（2）the best sowing time was after April 20 in Hunan;（3）the best sowing-depth should be 1.5 cm.
