核桃嫁接技术研究

以香玲、鲁光等早实薄壳核桃为试材,通过5年的嫁接试验研究,结果表明：中部饱满芽萌发时间短,成活率高,成活后生长速度较快;规模化生产最佳嫁接时间为春分前10天至清明后5天;接穗树龄越小,亲和力越强,成活率越高;覆盖黑色微膜能促进早生快发,抑制杂草。就近建立采穗圃,采用枝接与芽接相结合的方式,成活率能达到96%,产业化发展成活率达到88%以上,合格苗出圃率在80%以上。

Study on Grafting Technique for Juglans regia

Selected the earlier seed setting and thin shell variety of Juglans regia,such as the variety of Xiang-Ling and Lu-Guang as testing material.By 5 years grafting studies,the results showed that: used fruit bud of the central section plumpness to inoculated,the short time of bud germination,the high survival rate,and the soon speed of growth after survival.The best time grafting of scale production is 10 days before vernal equinox to 5 days after clear and bright.Used less tree age of scion to grafted,the str...
