生产实践中,经常用板栗实生苗造林,因而生长慢,结果迟。采用高位嫁接技术,可以改良品种,恢复树势,达到提早结果和实现丰产的目的。具体作法有以下两种: 一、幼树嫁接 一般在春季或秋季进行,采用多头芽接法,即在实生幼树的各分枝上,实行带木质盾形芽接,当年即可成形,而且可减少因嫁接不当造成死树的危险。可选用充实健全的当年生或上年生优良品种枝条,剪去两端,选留中段4—5芽做为接芽。在每个接芽上方1厘米处略带木
Production practice, often with chestnut seedlings afforestation, and thus slow growth, the results of late. The use of high grafting technology, can improve varieties, restore the tree vigor, to achieve early results and achieve high yield purposes. There are two specific practices: First, the saplings are generally grafted in the spring or autumn, the use of multi-bud method, that is, in the branches of the actual young saplings, the implementation of wood with a shield-shaped bud then, then can be formed, Danger of dead trees due to improper grafting. Can be used to enrich and improve the current perennial or perennial varieties of fine branches, cut both ends, leaving the middle of 4-5 buds as the pick bud. Slightly wooden at 1 cm above each bud
