果树树体的贮藏营养主要是碳水化合物(以淀粉为主)、蛋白质和脂肪等,这些物质贮存于皮层、木质部的薄壁细胞及髓中。树体的贮藏营养对越冬及下一个生长季节的萌芽、开花、抽梢展叶、生根、坐果、果实形成等过程的顺利完成都有显著的影响。因此,致力于提高贮藏营养水平,对果树的 Fruit trees are mainly stored carbohydrates (mainly starch), protein and fat storage, these substances stored in the cortex, xylem parenchyma cells and pith. The tree’s storage nutrition has a significant impact on the successful completion of the process of overwintering and the next growing season of germination, flowering, leaf-tip exhibition, rooting, fruit setting, fruit formation. Therefore, dedicated to improving the level of storage of nutrients on fruit trees
