摘要
试验结果表明：不同的白杨派品种对嫁接亲合力的敏感程度不同，敏感性最强的是白杨７４１，敏感性最低的是河北毛白杨；选用生长健壮的种条作接穗，伐根生长旺盛、直径在１０ｃｍ以上，嫁接时间掌握在４月份，且边平茬边嫁接是提高嫁接成活率的主要措施；毛白杨嫁接苗６月中旬至８月底为生长高峰期；其越冬抗寒性与品种有关，其中河北毛白杨和白杨７４１越冬抗寒性最好；其当年生长量与伐根直径大小有一定的相关性。
The experimental results of Populus tomentosa Carr. grafting on poplar stump indicat that the graft seedings of Populus tomentosa Carr. peaked in growth from the middle ten days of July to the end of August, and its cold resistance on winter relates to the varity. Populus tomentosa Carr. cv.Hebeinica and Populus 741 have the best of cold resistance, and the growth of that very year is related to the diameter of stump, but have no marked difference. Different varity of poplar have different susceptability to graft affinity, and Populus 741 have the highest ones and Populus tomestosa Carr.cv.Hebeinica have the lowest ones. Graft survival rate could be risen greatly by selecting robust seeding strip as grafts and vigorous stump with 10cm diameter, grafting in June, flating stubble and grafting at the same time .
