杂种核桃嫩枝扦插试验分析初报

根据以往核桃扦插的经验,选择‘强旱’、‘奇异’和‘99-1’3个杂交品种核桃野外成年树采集插穗,从不同时期、不同部位插穗、不同扦插设施条件等方面,研究分析杂种核桃快速繁育技术。结果表明,在5月下旬～6月中下旬插穗木质化程度最好,气温合适;基部插穗,在能控温的扦插温棚内扦插生根率最高。该方法可明显提高效益、降低成本。

Hybrid walnut twig cuttage test analysis report

Cuttings were collected from three hybrid varieties of field walnut adult tree of“Qianghan”,“Qiyi”and“99-1”according to previous walnut cutting experience. The paper researched and analyzed rapid propagation of hybrid walnut from different stages, different parts of the cuttings and different cutting conditions and facilities. The lignification degree of cuttings from late May to the end of June was the best. Basal cuttings in temperature controlling cutting greenhouse reached the highest rooting rate.
