核桃嫁接是培养优良品种,改造劣树、提高产量、质量、实现核桃栽培良种化促进核桃丰产、稳产的一项重要措施。过去,我省核桃(Juglans sigillata)芽接主要在3月份(春分前后十天)。未成活的要待第二年春季补接,又耽误一年的时间。因此,为了争取更多的嫁接时间,加速核桃的基地建设,我们从77年以来,在春季嫁接的基础上,连续在晋宁双河、漾濞核桃站和昆明金殿林场等地,先后进行了3000多 Walnut grafting is an important measure to cultivate fine varieties, transform poor trees, improve yield and quality, and achieve walnut cultivation and seed production to promote high yield and stable yield of walnut. In the past, our province Juglans sigillata budding is mainly in March (ten days after the equinox). Unsuccessful to take the second spring supplements, but also delayed a year’s time.
