丹东栗(C、SP·)属日本栗种,结果早、产量高,但有品质稍差,涩皮不易剥离,抗逆性不强的弱点。鉴于中国板栗(Castanea Mollissi ma)适应性强,较抗寒,果实品质好的优良性状,将丹东栗嫁接板栗有着一定的意义.近二年,在推广板栗嫁接过程中,发现丹东栗嫁接板栗的成活率极低.为此,我们进行了丹东栗与板栗亲合力试验。 Dandong chestnut (C, SP) is a Japanese chestnut species, early results, high yield, but the quality is slightly worse, astringent peel hard to peel, the weakness of resistance is not strong. In view of the adaptability of Castanea Mollissi ma and its good characters of cold resistance and good fruit quality, grafting chestnut of Dandong chestnut has a certain significance.In the past two years, during the promotion of chestnut grafting process, it was found that grafted chestnut of Dandong chestnut Very low survival rate.To this end, we conducted a test of affinity between Dandong chestnut and chestnut.
