在苹果矮化砧营养繁殖中广泛应用垂直压条法,这个方法并不复杂,但是在哈萨克斯坦南部夏季干热的条件下,我们在采用这个方法时却遇到了一些矛盾。这就是由于在干土中压条不生根,为了使其很好生根,就必须经常灌水,而高的土壤湿度又促进了压条苗地上部的旺盛生长,造成生长过度。另外,为了促进压条苗新梢生长,以便八月份在其上进行芽接,在第一苗圃地定植之前,必需在压条苗基部留2～3芽短剪,这也导致了压条苗的强旺生长。
The vertical bead method is widely used in vegetative propagation of dwarfing apple trees. This method is not complicated. However, we encountered some contradictions when using this method under the conditions of dry and hot summer in the south of Kazakhstan. This is because in the dry soil does not take root, in order to make it a good root, we must always irrigation, and high soil moisture and in turn promote the strong growth of the shoots above ground, resulting in overgrowth. In addition, in order to promote the shoot growth of shoots so as to be budded on them in August, it is necessary to have 2 to 3 shoots short at the base of the shoots before colonization in the first nursery, which also leads to the strong growth of shoots .
