1977年来,我们对6——10年生不结果或少结果的核桃幼树,采用插皮舌接的方法进行高接换种的试验研究。五年的高接试验表明,核桃高接成活率高,树体恢复快,增产效果显著。核桃高接换种技术已初步发挥出它的经济效益,并展示了改造核桃幼树低产林实现核桃栽培良种化品种化的广阔前景。
1977 years, we 6 - 10 year-old fruitless or less walnut trees, the use of tongue-in-tongue method for high-replacement test. High-five-year trial showed that walnut high access to high survival rate, the tree quickly restored, a significant yield increase. Walnut high exchange technology has played its initial economic benefits, and demonstrated the transformation of walnut trees and low-yielding walnut seedling cultivation of broad varieties of broad prospects.
