枣树采收,各地都用杆打的方法,不仅工效低,劳动强度大,而且伤害树体,影响来年产量。山东省果树研究所在四年多的科学实验和生产示范中找出一种提高工效,保护树体的采收方法。在枣成熟采收前7天,全树周密喷布200——300ppm 乙烯利水溶液一次,对果实成熟和催落效果明显,喷后2—3天果柄离层开始解体,5—6天后成 Jujube harvest, all over the way with a rod, not only low efficiency, labor-intensive, but also hurt the tree, affecting the production in the coming year. Shandong Fruit Research Institute in more than four years of scientific experiments and production demonstration to find a way to improve ergonomics, protection of tree harvesting methods. 7 days before mature jujube harvest, the whole tree is sprayed with 200 - 300ppm ethephon aqueous solution once, the fruit ripening and catching effect is obvious, 2-3 days after spraying the fruit stalk disintegrates, 5-6 days after the
