核桃接穗在贮藏、运输和嫁接过程中,常常由于失水过多,生活力降低,严重影响了嫁接成活率。为了探索减少核桃接穗水分蒸腾的简单有效方法,1977年春,我们曾用黄油、凡士林等涂抹接穗,由于这类油脂渗透力强,均有伤芽现象。1977年至1979年,我们改用石蜡密封接穗,并进行室内分析,为进一步应用蜡封接穗,提供了一定的理论根据。 During the process of storage, transportation and grafting, the scion of walnut often has the effect of losing water and reducing the vitality, which seriously affects the graft survival rate. In order to explore a simple and effective method of reducing the transpiration of walnut scion, in the spring of 1977, we used scouring with butter, petrolatum and the like, and as a result of these oils penetrated well, there were wound buds. From 1977 to 1979, we used paraffin wax to seal the scion and conducted indoor analysis, which provided some theoretical basis for further application of wax seal scion.
