苹果矮化栽培,可以大大提高集约化生产水平,已日益为国内外所重视。为了加强这方面的研究工作,我们在引进外来矮化砧木的同时,于一九七四年对省内苹果矮化砧木资源进行了调查。现将调查结果分述如下:一、砧木的分布:我省气候一般干燥冷凉,适宜苹果生长,因此,蔷薇科苹果属的半栽培种、野生种资源极为丰富,栽培历史也久。据《齐民要术》一书记载,远在一千四百多年前,绵苹果一类的果树,在河西地区已有栽培。这些半栽培种、野生种,具有抗寒、抗旱、
Apple dwarf cultivation, can greatly enhance the level of intensive production, has increasingly been valued at home and abroad. In order to strengthen research work in this area, we conducted an investigation into dwarfing apple rootstock resources in the province in 1974 while introducing exotic dwarfing rootstocks. The survey results are as follows: First, the distribution of rootstocks: the province’s climate is generally dry and cold, suitable for apple growth, therefore, Rosaceae apple genus semi-cultivated species of wild species is extremely rich in resources, cultivation history has long. According to “Qi Min Yao Shu” a book records, far more than 1,400 years ago, a kind of cotton apple tree fruit trees, has been cultivated in Hexi region. These semi-cultivated species, wild species, with cold, drought,
