Fruit tree fertilization time

1. Promote autumn basal fertilization, and carry out fruit harvest immediately. Improve the nutritional reserve of fruit trees and promote the development of fruit trees in the spring.

2, spring fertilization, in the root system in the first year of the first 15 days before the peak growth, generally in early March fertilization is over, it should be sooner rather than later.

3, June top dressing must be due to tree-trend, the result is more trees to chase, on the contrary less chase, saplings, no fruit trees do not chase.

4. Mild deficiencies can be supplemented with foliar dressing, which is economical and efficient, and saves time and labor.

Second, fertilization varieties

Fertilization should focus on increasing production and improving quality. Promote the application of organic fertilizers and eliminate the use of single chemical fertilizers.

1. The use of bio-organic fertilizer is the main reason, and the use of nitrogen, phosphorus and potassium is reasonable to achieve both high yield and high quality.

2. Advocate large-scale application of organic-inorganic compound fertilizers and various farmyard fertilizers and self-fertilizers to increase soil organic matter content and improve fruit quality.

3. Promote the use of locally available organic materials. Such as crop straw, weeds, leaves, etc. with a suitable amount of mineral elements, are very good organic fertilizer. These organic fertilizers are economical, efficient, low-cost, and rich in nutrients.

4. Chicken manure and pig manure should be used in orchards after high-temperature fermentation. It is forbidden to directly use raw chickens and pig manure in orchard farmland. Reduce soil contamination.

Third, the operation method

Promote the use of groove, radial, annular rotation method, do not advocate the ground. During this specific operation, you will learn to use the fertilization method this year and become a ring or radial method next year.

Rotate for three years to maximize the use of the limited land area in the orchard. The specific fertilization site of each tree should be in the center of the vertical projection of the crown. Because most of the absorption roots are distributed in the soil around the crown.
