日本的品种更新日新月异。但是现在,如果用传统的方法对品种进行高接更新,经济效益并不那么高。为了尽可能缩短无收获期,迅速达到优质高产,上山氏等对品种更新技术进行了深入研究,发明了快速获得收益的嫁接新技术——休眠式二芽腹接一举更新法。现介绍如下。一、技术特点过去的嫁接方法,嫁接时大量剪除中间砧木。因此,在做了大手术的同时,树体养分的损失和根的伤害均很大,不能早期获得产量。另外,嫁接树寿命短。而且在新梢立支柱和诱引方面需花费资材和劳力。休眠式二芽腹接法可大幅度改进这些缺点。简单地说,其操作步骤是:第一年让中间砧木维持原状,进行“二芽腹接”(由于 Japan’s variety updated with each passing day. But now, if traditional methods are adopted to upgrade the varieties, the economic benefit will not be so high. In order to shorten the harvest period as soon as possible and quickly achieve high quality and high yield, Shangshang et al. Conducted an in-depth study on the variety renewal technology and invented a new grafting technology that quickly reap the benefits-the dormant two buds one by one update method. Now introduced as follows. First, the technical characteristics of the past grafting methods, a large number of intermediate grafts cut when grafting. Therefore, at the same time of major surgery, both the nutrient loss of the tree and the damage of the root are so great that the yield can not be obtained early. In addition, the life of the grafted tree is short. It also costs money and labor to set up new branches and induce them. Sleeping two bud abdomen method can greatly improve these shortcomings. Briefly, the operation steps are as follows: in the first year, the middle rootstock is maintained as it is and the “two buds” (due to
