目前我国板栗良种的繁殖,一般是采用先育出实生苗,第二年或第三年移植,并在移植当年或第二年嫁接的方法。从播种至嫁接成苗一般需2-3年,育苗周期较长,故研究板栗良种快速繁殖技术,在生产上具有现实意义。板栗子苗嫁接的方法,国内外已有报道。1965年美国康纳奇特农业实验站板栗子苗嫁接取得效果,但成活率仅38.4％,嫁接方法和设备亦复杂。后来,日本籐井利重把这种方法叫做保育种子砧嫁接法。国内1979年开始试验,1982年《山东果树》报道过山东果树研究所尤
At present, the propagation of chestnut breeds in China is generally based on the methods of grafting seedlings first, second or third year, and grafting in the year of transplantation or the second year. From sowing to grafting seedlings generally take 2-3 years, a longer incubation period, so the chestnut seeds rapid propagation technology, in the production of practical significance. Chestnut seedling grafting methods, both at home and abroad have been reported. 1965 Conakachent agricultural experiment station chestnut seedlings grafted effect, but the survival rate of only 38.4%, grafting methods and equipment are also complicated. Later, Fujiiri Japan called this method the seed grafting method. Domestic trials began in 1979, 1982, “Shandong fruit tree” reported in Shandong Institute of fruit especially
