前言果树高接栽培能提高栽培品种的抗寒力,主要是借助于抗寒中间砧抵御严寒低温的不良气候,改变了树体结构,中间砧对接穗的生长结果产生影响,从而提高栽培品种的越冬抗寒力。由此可见,中间砧的选择具有重要意义。目前,我省苹果高接栽培,多数是对现存的低劣品种进行高接换头,改良品种。对中间砧还没有人进行栽培鉴定和选择,为推广高接栽培很有必要研究提出适合我省特点的中间砧。因之,研究为生产提供抗寒、抗腐烂病、丰产、适应性强的中间砧,是当前我省果树栽培上一个重要的课题。1973年开始进行了苹果中间砧栽培试验,已进行
Preface High-yielding fruit trees can improve the cold-tolerance of cultivars, mainly through the help of cold-resistant anvil to resist the cold climate of low temperature, change the structure of the tree, and the intermediate anvil has an impact on the growth of scions, Winter cold resistance. Thus, the choice of the middle anvil is of great significance. At present, the cultivation of apple in our province is carried out in a high way, most of which are carried out on the existing inferior varieties and improved varieties. It is necessary to study and propose the middle anvil that is suitable for our province to promote the cultivation of high-yielding cultivars. Therefore, research to provide cold-resistant, anti-rot disease, high yield, adaptable intermediate anvil is an important issue in fruit cultivation in our province. Apple began in 1973, an intermediate rootstock cultivation test has been carried out
