前言砧木是果树赖以生长发育的基础,它对果树的结果早晚、产量高低、品质好坏、成熟迟早、耐藏、抗病以及对不良环境条件的适应能力,都有一定的影响,因此砧木研究工作一向被各国园艺学者所重视。为了充分利用本省的砧木资源,并为荒山、沙滩和盐碱地区发展果树,提供砧木区域化的意见,本所从1956年开始,至1963年,先后与山东省果树研究所、烟台 Introduction Rootstock is the basis for the growth and development of fruit trees. It has some effects on the fruit yield, quality, maturity, storage resistance, disease resistance and adaptability to adverse environmental conditions. Therefore, rootstocks Research has always been valued by horticultural scholars in various countries. In order to make full use of the province’s stock of rootstocks and to develop fruit trees for barren hills, beaches and saline-alkali areas and provide advice on the regionalization of rootstocks, the Institute started from 1956 to 1963 and met with Shandong Fruit Research Institute, Yantai
