Three choices: First, select fertilizer varieties: According to the high and low nutrient content of available nitrogen, phosphorus and potassium in the soil, based on the principle of balance of supply and demand, select the appropriate proportion of nitrogen, phosphorus and potassium compound fertilizer. At the same time, according to the pH of the orchard soil, choose fertilizers with different characteristics. The second is to select the amount of fertilizer: on the basis of soil testing, calculate the amount of fertilizer based on how much nutrient the fruit tree needs. The third is to choose the fertilization method: this is very important in the current orchard production management. Common fertilization methods include strip ditch application, annular ditch application, radial ditch application, and point application. The first two fertilization methods are suitable for autumn fertilization. Three combinations: First, the application of organic fertilizer (referring to man, livestock, poultry manure, straw, cake made of fertilizer) combined with the application of fertilizer; second, the application of a large number of elemental fertilizer and trace element fertilizer; three is fertilization and pouring Water is combined.

Fruit tree autumn fertilization "three look", "three choices" and "three combinations"
Look at it: Look at the tree potential: For the fruit trees with weak trees, the amount of fertilizer should be increased appropriately; for fruit trees with deficiency, the medium and trace element fertilizers should be applied in a targeted manner; the difference between the young trees and the fruit trees should be different. Fertilize. Second, look at the soil nutrient content: through the agricultural department to carry out soil tests, to understand the level of each nutrient content, to make up for the lack of compensation, how much to fill. Third, the target production of the year: Under normal circumstances, when the target output is high, the amount of fertilizer applied in autumn is correspondingly larger; when the target yield is low, the amount of fertilizer is correspondingly less. Determine the target yield, based on the average yield of the first 3-4 years of the orchard, increase the yield by 10%-15% (this method can be used in orchards that enter the stable result period).
