丝棉木嫁接北海道黄杨试验初报

Experimental Report on Engrafting Euonymus japonicus Thunb into Euonymus buneanus Maxim

利用丝棉木嫁接北海道黄杨,改变北海道黄杨在宁夏地区露地越冬易风干、抽干的现状,提高北海道生长量和增强抗寒、抗风干能力。采用同一砧木,嫁接时间不同、接穗采取部位不同,嫁接成活率、新梢生长量、茎粗有明显差异。试验结果表明:利用无分枝的接穗嫁接,成活率及生长量均大于分枝接穗。

Engrafting Euonymus japonicus Thunb into Euonymus buneanus Maxim had been a good way to resolve the branch air-dry of Euonymus japonicus Thunb planted in Ningxia in winter without any protective measures, and could increased the growing-amount and the ability to resistant the cold and air-dry. This paper studied the engrafting. Having the same stock, different engrafting-time and graft got from different place on tree made different engrafting-survival-rate and new branch-growing-amount. The result was that the engrafting-survival-rate and new braneh-growing-amount of engrafting by graft with branch was better than thoes of by graft without branch.
