The annual mean temperature and other 10 climatic factors were selected as the main factors for comparison by using the method of Euclidean fuzzy distance similitude priority ratio. The sequence of similarity degree of climatic and ecological conditions of 126 cities or stations in China and of the main persimmon production region in Japan were analyzed by QBASIC programme. And the China’s suitable climatic and ecological region for introducing Japanese sweet persimmon ( Diospyros kaki ) were divided in the light of practical introduction and cultivation experiments. The authors divided China into 3 climatic and ecological regions according to their suitability for cultivating Japanese sweet persimmon.
甜柿是柿(Diospyros kaki Linn.f.)树的自然类型,属日本主要栽培果树之一,其特点是果实采后不需人工脱涩即可食用,甜脆爽口,风味独特。近年来,日本甜柿已在我国大量引种栽培,国内对甜柿的生物学习性和栽培方法已作了不少观察和研究。但对甜柿果实的生长发育过程及果实发育期间生化物质消长规律的研究尚未见报道。
