以优质核桃当年生二次枝饱满芽体为接穗,进行夏季方块芽接和带木质部芽接。比较2种嫁接方法发现过早期嫁接核桃成株率低于中晚期。早期带木质部芽接成株率高于方块芽接,晚期方块芽接高于带木质部芽接。比较成株率发现最佳的嫁接时期为6月中旬,并且选择适宜时期嫁接壮芽,嫁接时注意保护芽体,可有效提高嫁接核桃成株率。 High-quality walnuts in the current secondary branches full Bud body scion, summer budding and buds with xylem bud. Comparison of two kinds of grafting methods found that early grafting walnut plant rate lower than the late. Early with xylem budding plant rate higher than the block budding, late box budding with xylem budding. Comparison of adult plant rate found that the best grafting period in mid-June, and select the appropriate period of grafting strong buds, grafting attention to protect the bud, which can effectively improve the rate of adult plant grafted walnut.
