How to conduct soil testing and formula fertilization in apple trees
Apple tree needs fertilizer characteristics The apple orchard soil testing and formula fertilization is the most effective technical measure to improve the soil fertility of the orchard and timely supply the nutrients needed for fruit tree growth. The soil fertility required by the apple tree: First, the soil pH should be suitable, and the soil pH is 5.3-8.2. The apple tree can adapt to different pH of the soil by selecting different rootstocks. Second, the soil layer should be deep, and the depth of the soil layer should exceed 60 cm. Because the root layer of apple mature trees is mainly distributed in 40-60 cm, the deep soil layer is conducive to the extension of the apple tree roots to the deep and wide areas, increasing the fertilizer and water. Absorption area. Third, the soil organic matter content is rich, and the soil organic matter content is more than 1%. This is the basic condition for strong trees, high yield and high quality. The fourth is that the soil has a balanced supply of nutrients, and the apple tree is a tree species with high yield per year and long economic utilization. It has been grown for many years and absorbs many nutrients from a certain soil range. The deficit is therefore necessary to adjust soil fertility through soil testing every year. Apple tree formula fertilization technology The application of organic and inorganic fertilizers to increase the application of organic fertilizers is the basic measure to improve the physical structure and chemical properties of apple orchard soil. Organic fertilizers are long-lasting and slow, and chemical fertilizers are fast and short-lived. The combination of the two can be used for quick recovery and complementary length, and can supply the required nutrients during the growth of the apple.

Nitrogen, phosphorus, potassium, medium and trace elements are used in combination with the growth and stoppage of roots, buds, branches and leaves of apple trees, flower bud differentiation, flowering results, fruit enlargement and maturity, etc., and rhythmically and proportionally absorb various nutrients. element. Various nutrients are equally important and irreplaceable to apple trees. Therefore, on the basis of increasing the application of organic fertilizer to deepen the soil, we must also pay attention to the combined application of chemical fertilizers such as nitrogen, phosphorus, potassium, medium and trace elements, pay attention to the application of multiple compound fertilizers, and coordinate the proportion of various nutrients to meet The need for good growth and high yield of apple trees.
