补充资料:温带果树
适应在温带气候条件下生长的果树。主要分布在北纬或南纬30°~60°之间,绝大多数为落叶果树。包括:仁果类,如苹果、梨、山楂、榅桲等;核果类,如桃、杏、李、梅、樱桃等;浆果类,如葡萄、柿、猕猴桃、草莓、树莓、越橘、醋栗等;坚果类,如核桃、板栗、榛、银杏、山核桃、阿月浑子等。温带果树在世界果树生产中占有重要地位。苹果、梨、柿、枣等的产量约占中国水果总产量的四分之三。
温带果树不耐酷寒;但与热带和亚热带果树相比,生长季热量要求较低,冬季抗寒力较强,并有自然休眠的特性,需要一定时间的低温,才能完成休眠、正常生长和开花结实。这种适应性在不同的树种、品种之间也有差别。如苹果、梨、杏、樱桃、板栗、榛、树莓、越橘、醋栗等适宜较冷凉的地区;而柿、枣、葡萄、桃、李、核桃等则适宜较温暖的地区,其中柿、枣等温带果树的南方品种群也广泛栽培于亚热带,而可被认为是亚热带果树。但总的来说,绝大多数温带果树不适于在热带和亚热带栽培。
