为了改变我省实生核桃树晚实、低产、劣质的现状,加速核桃无性系苗木繁殖和掌握核桃树高接换头的技术关键,我们在总结过去省内嫁接经验的基础上,于今年3月下旬组织全省核桃嫁接技术人员赴河北省获鹿县参观学习。1981—1984年河北农大与河北省获鹿县林牧局在横山大队进行了核桃大树多头高接和苗圃枝接的试验研究,结果表明:蜡封接穗插皮舌接法操作方法简便易行,成本低易于推广,嫁接速度快,成活率高。圃地枝接成活率三年稳定在90%以上,大树多头高接,接头成活率在90%以上,接
In order to change the real walnut trees in our province late, low yield, low-quality status quo, accelerate walnut clonal propagation and control of walnut tree high exchange head technology, we summarized the past grafting experience in the province on the basis of this year in March The province organized the province’s walnut grafting technicians went to visit the study of the county of Hebei Province. In 1981-1984, Hebei Agricultural University and Hebei Animal Husbandry Bureau, Shuxu County, Hebei Province, carried out experimental research on the branches and branches of walnut tree and the nursery in Hengshan Brigade. The results showed that the operation method of wax seal scion plugging tongue connection method was simple and easy Low cost Easy to popularize, grafting speed, high survival rate. Branch to live in the survival rate of three years more than 90% stability, the tree long high pick, joint survival rate of more than 90%, then
