针对板栗大树高接换头中伤流导致嫁接成活率下降等问题进行了释根压生产试验,试验结果表明:采取在嫁接口之下刻伤的方式对根压进行释放,可降低或减缓伤流液在紧密包扎着的塑料薄膜内积存,有利于愈伤组织形成,提高嫁接成活率,防止病变,促进萌发枝发育。该研究结果对提高板栗大树高接换优成功率具有生产指导意义。
Aiming at the problem of the survival rate of the grafting in the high head replacement of the chestnut tree, the rooting pressure production test was carried out. The results showed that the root pressure release could be achieved by means of engraving under the grafting interface, which could reduce or reduce the injury Liquid in the tightly packed plastic film is stored, is conducive to the formation of callus to improve the graft survival rate, prevent lesions, and promote the development of germinating branches. The results of the study to improve the success rate of chestnut tree height transfer with production guidance.
