想短期内得到自己喜欢的樱花大苗,高接换头是个好办法。进行高接换头的树龄最好在6年以内,因为树龄越大,嫁接和管理工作量就越大,而且有的因树龄过老,树势衰弱,高接后也不易长出旺盛的枝条来。樱花的高接换头分为一次性换头和渐进性换头两种。一次性换头虽然嫁接后发育良好,但缺点是更新期内不能观赏。而渐进性换头是在确保有一定观赏价值的基础上对大枝逐步进行高接换头的方法,但此法留下大而直立的旧有品种枝条,易造成嫁接枝生长不良。所以在实践中,一般还是采用一次性高接换头法。一般在早春萌芽前进行。
Want to get your favorite cherry seedlings in the short term, high takeover is a good way. The best age for high exchange heads is within 6 years, because the bigger the tree age, the greater the workload of grafting and management, and some may be hard to grow strong branches due to age Come. Sakura high interchangeable head is divided into one-time replacement and gradual change head two. Although the one-time replacement head well after grafting, but the disadvantage is that during the update can not watch. Gradual change of head is to ensure that there is a certain appreciation of the value of the main branches gradually high replacement method, but this method leaves large and upright old varieties branches, easily lead to poor growth of grafted branches. Therefore, in practice, the one-shot transfer method is generally adopted. Generally carried out in early spring budding.
