山地红富士苹果优质丰产栽培技术

HIGH YIELD AND SUPERIOR QUALITY CULTIVATION TECHNIQUES FOR FUJI APPLE IN MOUNTAINOUS AREA

１９９１～１９９６年对五莲县山地红富士苹果结果树采取深翻改土、配方施肥、覆草、套袋、摘叶转果、铺反光膜、合理修剪及防治病虫害等优质丰产栽培技术措施，结果表明，全县５００多ｈｍ２开发园，一级果率、果实着色指数及品质等都优于对照园。开发６ａ，平均每公顷产量４１５４１ｋｇ、产值２２７７０５元，比对照园１８６７９．５７ｋｇ和４１０９５．０５元，分别增加２２８６１．４３ｋｇ和１８６６０９．９５元，经济效益显著。

We have developed a series of techniques of high yield,fine quality and high benefit for mature Red Fuji apple trees on hilly land in Wulian county from 1991 to 1996.The main measures adopted are:turning soil up deeply and changing the surface soil over to new soil,applying fertilizers in production,mulching,baging,picking off leaves and turning fruits to expose to sun light,covering reflection film,suitable training and pruning system,pest and disease control etc.The result indicates that the developed orchard is better than the control in many indicators such as the first class fruit rate,color and quality etc.After 6 years of development,the average out put is 41541 kg/hm2, 227705 /hm2in value and the control orchard is 18679.57 kg/hm2, 41095.05 /hm2in value ,showing remarkable benefit.
