为了配合良种场板栗良种大面积推广 ,自 1994年开始 ,我们以改进接穗削法为突破口 ,经多项试验分析验证 ,创造了二刀一剪法秋季单芽贴接新技术 ,秋季嫁接成活率均在 90 %以上 ,效果十分显著。1　研究方法与试验材料1.1　二刀一剪法的提出板栗枝 (干 )富含单宁、木质坚硬、皮层 In order to cooperate with the popularization of good chestnut varieties in good field, since 1994, we have taken the improvement of scion cutting as the breakthrough point. After several experiments and analysis and verification, we created the new technology of single-stick and fall-in-the-shoot in autumn and autumn and the grafting survival rate in autumn Are more than 90%, the effect is very significant. 1 research methods and test materials 1.1 two knife and one shear method proposed chestnut branches (dry) is rich in tannin, hard wood, cortex
