摘要
根据农业部在80年代两次组织评选出的全国189个优质水果产地的生态环境资料,用微型电子计算机系统建立数据库,统计分析柑桔、苹果和梨优质产品的构成比例、产区分布地域及其适宜的环境指标和主栽品种的生态适应性,为果树良种区域化栽培与选育提供依据。
In this study, a datum base was estabilished by a microcomputer system, using lots of ecological data collected from the homes of mainly superior fruit species which were appraised by the Ministry of Agriculture, through twice nationwide comparisons in the 1980s. The proportion of products coming from mainly superior fruit species such as citrus, apple and pear, their geographical distribution of homes and optimum ecological indexes were evaluated according to the data of mathematically statistical analysis. Ecological adaptabilities of major cultivars were analysed as well. Furthermore, a regional assignment and production planning of the mainly superior fruit species and their major cultivars were also discussed and suggested for the national development programme of production and selection in the future.
