目前,在我县核桃芽接成活率一直不够稳定。在嫁接愈合生长过程中,接芽受到一定的温度、湿度、光照、植株的生长势、亲和力、砧木的处理及操作技术等多方面的影响。根据我们1980年的观察,在嫁接时选用背阴面比向阳面好,成活率高。1980年6月18日,在省林科所召开全省核桃芽接试验交流会上,全体与会同志四十余人,由南向北每人一畦进行嫁接。同时,本人试验性地采用了北、东北2个方位,共嫁接23株,9月份检查成活19株,成活率为82％;而其他同志嫁接在南、西南2个方 At present, the survival rate of walnut buds in our county has not been stable enough. During the process of grafting and healing, the buds are subjected to various influences such as temperature, humidity, light, plant growth potential, affinity, rootstock handling and operation techniques. According to our observations in 1980, the choice of grafting better than the sunny side of the shady, high survival rate. June 18, 1980, held in the province of Linke branch of the province’s walnut bud test exchange meeting, all the participating comrades more than 40 people, from south to north, one for each grafting. At the same time, I tentatively adopted the north and northeast 2 azimuths, a total of 23 grafted, 19 survived in September check, survival rate was 82%; while other gay grafts in South and Southwest 2 parties
