为了加快苹果良种的繁殖和推广,近几年来我们采用了“以苗萦苗”的快速繁殖法,取得了良好效果。这种方法的优点是:(一)苗木繁殖速度快。一株良种苗木,经过三、四年时间,即可繁殖十来万株,甚至数百万株(即每年按40-50倍的繁殖率扩大繁殖)。(二)用此法繁殖的无性系后代,其结果期和果实性状与普通方法(从结果树上采接穗嫁接)繁殖的后代没有差异。一、具体方法在辽宁省南部的条件下,一般用二年生山荆子作砧木的苹果嫁接苗,当年生长高度可达1.5-2米。这样快的生长量,便为采用“以苗繁苗”法快速生产接穗创造了有利条件。我们的做法是:将苗干进行摘心,促使摘心部位以下发生副梢,秋季用副梢作接穗进行芽接,翌年春季再利用苗干的延长枝作接穗进行枝接,从而加快了繁殖速度。操作要点是:在苹果嫁接苗长到30-45厘米时进行苗干摘心,摘去3-5厘米长的嫩尖。“元帅”、“金冠”等品种 In order to speed up the breeding and popularization of apple varieties, we have adopted the rapid propagation method of “Miao Miao” in recent years and achieved good results. The advantages of this method are: (A) seedling propagation speed. A seed of seedlings, after three or four years, you can breed ten to ten thousand, or even millions of strains (that is, 40-50 times the annual expansion of breeding multiplication). (2) There is no difference between the offspring of clones propagated by this method and the offspring of the fruit of the fruit and fruit traits and the common method (grafting from the result tree). First, the specific method In the southern province of Liaoning conditions, the general use of perennial tree seedlings of apple grafted seedlings, when the height of up to 1.5-2 meters. Such a rapid growth, it will create a favorable conditions for the rapid production of scion “seedlings and seedlings” method. Our approach is: the topping of the seedlings topping, to promote the occurrence of the following pinaculata acuminata shoots in the fall, with the next shoot for scion spike, the spring of the next year to re-use of seedlings stems for the extension of the branches for the spike, thus speeding up the breeding speed. Operating points are: Apple grafted seedlings to 30-45 cm long seedlings topping, picking 3-5 cm long tender tip. “Marshal”, “Golden Delicious” and other varieties
