通过试验和调查研究，对红富士苹果套袋技术作了较详细阐述。红富士苹果花后40天开始套袋，果实在袋内需90天生长发育，采收前20～35天为摘袋适期。并对红富士苹果套袋栽培在疏果、防治病虫、袋类别、套袋时期、提高套袋果含糖量等方面所存在问题提出对策和建议。 Through experiments and research, Fuji apple bagging technology made a more elaborate. Red Fuji apple bagging began 40 days after flowering, the fruit in the bag needs 90 days of growth and development, 20 to 35 days before harvest picking period. And put forward countermeasures and suggestions on the existing problems in the bagging cultivation of Red Fuji apple such as thinning, pest control, bag type, bagging period and raising the sugar content of bagging fruit.
