一、苹果的养根壮树 根系是整个树体生长发育的基础,壮树须养根。根的生长受土壤环境条件和树体营养的影响。瘠薄山丘地的土壤通透性较好,但土层薄,有机质含量低,水土流失严重,保水保肥力差。苹果园地下管理应注重创造土壤最佳水肥气热环境。

First, the root of apple root system is the basis for the growth and development of the whole tree, strong tree root culture. Root growth is affected by soil environmental conditions and tree nutrition. The soil in the barren hills is more permeable, but the soil is thin, the content of organic matter is low, soil erosion is serious, and water and fertility is poor. Apple orchard management should focus on creating the best soil and water fertilizer hot environment.
