I. Fertilization period: The fertilization period of fruit trees is based on the growth rules of the roots of fruit trees to determine the period, method, type and dosage of fertilization. The effects of the various fertilization methods appear to be the same, but their properties are quite different. Therefore, fertilization of fruit trees should establish a scientific concept of development and use a scientific attitude and scientific method to guide fertilization of fruit trees. 1. Promote the application of basal fertilizer in autumn, and immediately after harvest. Improve the nutritional level of fruit trees and promote the development of fruit trees in spring. 2. Fertilization in spring, 15 days before the peak of the first growth of the root system in a year, generally fertilization ends in early March, it should be early but not later. 3. The topdressing in June must be determined by the tree's vigor. As a result, more trees are chased more, otherwise they are chased less. Young trees and fruitless trees are not chased. 4. Mild fertilizer deficiency can be supplemented by foliar topdressing, which is economical and efficient, and saves time and labor. Fertilizer Varieties Fertilization should focus on improving yield and quality. Promote the use of organic fertilizers and eliminate the use of a single chemical fertilizer. 1. Bio-organic fertilizer-based, reasonable use of nitrogen, phosphorus, and potassium to achieve both high yield and high quality. 2. Advocate a large number of application of organic and inorganic compound fertilizers and various farm manures and self-fertilizers to increase soil organic matter content and improve fruit quality. 3. Promote and apply local ready-made organic substances. For example, crop straws, weeds, leaves, etc. with suitable mineral elements are good organic fertilizers. These organic fertilizers are economical, efficient, low cost and rich in nutrients. 4. Chicken manure and pig manure should be fermented at high temperature before they can be used in the orchard. It is strictly forbidden to directly use raw chicken and pig manure in orchard farmland. Reduce soil pollution. Operation method The method of ditch, radial and circular rotation is advocated, and ground application is not recommended. During the specific operation, master the furrow fertilization method this year, and turn it into a ring or radial method next year. Rotate every three years to maximize the limited land area in the orchard. The specific fertilizing part of each tree should be grasped at the middle and outer periphery of the vertical projection of the crown. Because most of the absorbing roots are distributed in the soil around the canopy. Disclaimer: Some articles on this website are transferred from the Internet.
