苹果的贮藏营养是指贮藏于根、干、枝中的养分,包括碳水化合物、蛋白质、氨基酸及维生素、激素等。从苹果生产的长期实践中,使我们认识到苹果产量的高低和大小年的幅度,与贮藏营养水平关系极大。因为花芽的形成、座果率的高低、果实的大小,都与贮藏营养密切相关。贮藏养分多的树,花芽形成多,花芽质量高,春季开花早而整齐,座果率相应也高。果实的大小决定于细 Apple’s storage of nutrition is stored in the roots, stems, branches of nutrients, including carbohydrates, proteins, amino acids and vitamins, hormones and so on. From the long-term practice of apple production, we have realized that the magnitude of apple production and the magnitude of annual size have a great relationship with the nutritional level of storage. Because of the formation of flower buds, the rate of fruit set, fruit size, are closely related with the storage of nutrition. Storage of more trees, flower buds and more flower buds of high quality, flowering early and neat spring, the corresponding fruit rate is also high. The size of the fruit is determined by the fine
