安徽省地方国营锡山果园场为了扩大砧木资源,加速苹果、梨的繁殖速度,1959年在大面积上应用了环株根接法,培育了梨苗28,760株,苹果苗38,982株,当年已有93%达出圃标准。环株根接的方法是:在春季把去秋芽接的苹果、梨苗或2—3年生幼树四周的侧根扒出土来,距侧根基部10—15厘米处剪断,于剪口处行根接,根接的方法以腹接为主,直径0.3厘米以下的细根则行倒接;接穗上端第一芽与地面相平,顶上复土,约高出接穗上端第一芽1—2厘米。应用这种方法,苹果苗成活率为66%,梨55%,一般每株可按2—5穗。有一株梨苗最多接35穗,成活28穗;有一株苹果苗最多接23穗,成活17穗。嫁接后的母株苗因还保留一定量的根系,生长并未受到多少抑制,而当年的根接苗生长亦很好,有不少当年还
In order to expand the resources of rootstocks and speed up the propagation of apple and pear, the local state-run Xishan Orchard Farm in Anhui Province applied ring root method to large area in 1959. It cultivated 28,760 pear seedlings and 38,982 apple seedlings, of which 93 % Reached nursery standards. Root ring ring method is: in the spring to the autumn budding apple, pear seedlings or 2-3 year-old sapling around the lateral root excavated from the side of the base 10-15 cm cut at the root of the cut root Then, the root of the way to the main abdominal connection, the diameter of 0.3 cm below the fine roots are inverted; the first spike above the ground with the first phase of the ground, the top of the earth, about the first spike above the top of the scion 1-2 cm. Application of this method, the survival rate of apple seedlings 66% pear 55%, generally 2-5 spike per plant. A pear seedlings up to 35 spikes, 28 spikes survive; have an apple seed up to 23 spike, survive 17 spike. Grafted mother plant seedlings because of the retention of a certain amount of roots, growth has not been much inhibition, and then the root pickling growth is also very good, there are many that year
