对当今国内外近千个苹果品种中筛选引入的早熟优质型、金冠类 (乔纳金系、嘎拉系 )、元帅系 3～ 5代浓红短枝型、富士系 2～ 3代早生短枝型和优质大果型 5大类 34个现代新优代表品种 ,通过在中亚热带湿热少日照常绿阔叶林生态型区的生物学特性与生态反应的研究结果表明 :7个品种在定植后第一年即开花结果 ,34个品种在第三年全部正常开花结果 ,且南部魁、新嘎拉产量分别达到 2 0 81 2 5kg/6 6 6 7m2 、2 0 39 6 3kg/6 6 6 7m2 。与温带地区相比 ,果实成熟期提前 15～ 30d ,生育期短者仅 45d。具有早果丰产特性和淡季供市的优势。幼树具有营养生长量大、超长枝多、多次生长特性和超长果枝、多次果枝、腋花芽果枝结果特性 ,这些构成了早果丰产的结构基础。对 10个品种果实外观、内部品质 ,抗逆性和适应性等的 18个生理、生态、形态结构指标进行了测试分析。综合评价表明 ,南部魁、新嘎拉是适宜于该生态型区主栽的首选品种。
At present, nearly one thousand apple varieties at home and abroad were introduced into the precocious high-quality, golden crown class (Jonathan, Gala series), the marshal is 3-5 generations of red spur type, Fuji 2 to 3 generations of short The results showed that the biological characteristics and ecological response of the ecotypes in ecotone of evergreen broad-leaved forest in subtropical zone of mid-subtropical China showed that seven cultivars The first year after flowering results, 34 varieties all flowering in the third year of the normal results, and the southern Quebec, the new Gala output reached 2 0 81 2 5kg / 6 6 6m 2, 2 0 39 6 3kg / 666 7m2. Compared with the temperate regions, the fruit ripening period is 15-30 days earlier and the shortest growth period is only 45 days. With early fruit yield features and off-season for the market advantage. Saplings have the features of large vegetative growth, long and long branches, multiple growth characteristics and long fruit branches, multiple fruit branches and axillary flower bud fruiting branches, which constitute the structural basis of early fruit yield. Eighteen physiological, ecological and morphological indexes such as appearance, internal quality, resistance and adaptability of fruit of 10 cultivars were tested and analyzed. Comprehensive evaluation shows that the southern Quebec, the new Gala is suitable for the main type of ecological district planted varieties.
