【摘要】 为了探索影响核桃露地芽接成活的主要因素,于2000—2002年开展了核桃露地芽接技术的试验研究,结果表明:核桃最适宜芽接的时期为6月份,采取对一年生砧木苗在发芽前进行平茬、在新梢上嫁接、雨季嫁接在接后5～7d复绑、干旱时在接前3～5d对苗圃浇水等措施可明显提高芽接成活率,而早实和晚实品种的嫁接成活率则无明显差异。更多还原

【Abstract】 In order to explore the main factors that effects the survival rate of Walnut bud grafting in open air, it conducts test and study on Walnut bud grafting in open air techniques during the period of 2000—2002. The results show that the best Walnut bud-grafting period is in June. Adopting the measures of one-year stock pruning before budding, grafting in the new tip of a tree in rainy season, rebinding after 5～7 days grafting and irrigating the nursery 3～5 days before grafting in dry condition can notably increase the survival rate of bud grafting. There is no clear difference for the survival rate of grafting early and late varieties.更多还原
