果树能否丰产,品种是关键。同样的品种,在某一地区丰产,在另一地区表现又有差异;同一地区,同一品种,经过年长日久的演变,品种也会退化。因此,近年来,贵州不少果园进行品种更替;新品种不断涌进,老品种不断淘汰。这种“新陈代谢”,给低产果园带来新希望。而品种更换,应采取什么技术措施,才能达到早结果早丰产,是当前高接换种所面临的重要问题。通过多年实践,我们体会到多芽高贴接是高接换种的好方法,是改造低产果园的良方。 Fruit trees can yield, variety is the key. The same species, yielding in one area, and showing differences in the other area; the same area, the same species, after years of evolution, the species will degenerate. Therefore, in recent years, many varieties of orchards in Guizhou change; new varieties continue to pour into the old species continue to be eliminated. This “metabolism” brings new hope to low-yield orchards. The species change, what technical measures should be taken in order to achieve early results early yield, is the current high accession to face an important issue. Through many years of practice, we have realized that high budding and high sticking is a good way of high-yielding and high yielding and a good way to transform low-yielding orchards.
