[目的]改变核桃嫁接成本居高不下的现状,拟通过技术手段降低苗木繁育成本。[方法]采用方块芽接方法以,分析砧木处理和剪砧时期对嫁接核桃生长状况和成本的影响。[结果]平茬的成活率高于不平茬的成活率,但可嫁接比例较不平茬的低了9个百分点,且平茬处理成本略高于不平茬处理的成本;不同剪砧时期造成的成本差异十分明显,嫁接后15 d剪砧成本是嫁接后1 d剪砧成本的5倍。[结论]砧木不平茬可令苗木管理简单方便,虽成活率有所降低,但总体成本低;嫁接后嫁接口上部砧木去除时期越早越好,嫁接后5 d内剪除同,不仅可以提高苗木质量,还会大幅降低苗木管理成本。
[Objective] To change the current situation that the cost of walnut grafting is high, and to reduce the cost of nursery stock breeding through technical means. [Method] The method of square budding was used to analyze the effects of rootstock processing and shearing period on the growth status and cost of grafted walnut. [Result] The survival rate of stubble was higher than that of stubble, but the ratio of stubble to stubble was 9 percentage points lower, and the cost of stubble treatment was slightly higher than that of stubble treatment; The cost difference is obvious. The cost of the 15 days after grafting is 5 times the cost of the 1 day after the grafting. [Conclusion] The rootstock not stubble can make the seedling management simple and convenient, although the survival rate is reduced, but the overall cost is low. The earlier the rootstock removal time after the grafting in the grafting is, the better, and the same can be cut within 5 days after grafting, which can not only improve the seedling Quality, but also significantly reduce the cost of nursery stock management.
