目前我国苹果年产200多万吨,提高苹果品质已成为苹果生产和科研中的主要课题。近年来,中国农业科学院就此问题组织了全国科研协作,取得了可喜成果,现举几例供生产上参考应用。元帅系苹果个大、皮色鲜艳、肉质爽脆、甜酸适度、品质上等,产量约占我国苹果的15%。但元帅系苹果属中熟品种,在我国主产区采收前至采收期气温较高。不利于果实物质积累和转化。因此果色浅、风味不浓,对贮运条件要求较高。采后如不及时降温贮藏,就很快发绵,失去原有品质风味,甚至腐烂。生产受到很大限制。山东果树所等单位经多年多点试验 At present, our country produces more than 2 million tons of apples annually. Improving apple quality has become a major issue in apple production and research. In recent years, the Chinese Academy of Agricultural Sciences organized a national scientific research collaboration on this issue and made gratifying achievements. We will give a few examples for reference in production. Marshal Department of a large apple, bright skin color, crisp meat, sweet and sour moderate, high quality, yield about 15% of China’s apple. However, the Marshal Department of the apple is a medium-maturing varieties, the main producing areas in China before harvest to harvest temperature is high. Not conducive to the accumulation and transformation of fruit material. Therefore, light color, flavor is not strong, higher requirements for storage and transportation. After harvesting if not timely cooling storage, quickly sponge, loss of the original quality of flavor, or even decay. Production is greatly limited.
