NPK 20-5-20 is a compound fertilizer with high nitrogen, medium phosphorus and high potassium content, which is highly suitable for the needs of apple trees during their vigorous growth period (spring to early summer) and fruit expansion period (summer). The following are its specific applicable methods and precautions
Applicable period
·From the time of spring sprouting to before flowering: Promote the growth of new shoots and the development of leaves, laying a foundation for flowering and fruit setting.
·From flower drop to the young fruit stage: Supports the cell division and early expansion of young fruits, as well as the continuous growth of spring shoots.
·Fruit expansion period (critical period) : This is the time when the formula can best exert its advantages (usually in summer). High potassium can significantly promote fruit enlargement, sugar increase, coloring and quality improvement. Meanwhile, an appropriate amount of nitrogen ensures leaf function and provides photosynthetic products for fruit growth.
·After fruit harvest (as appropriate) : If the tree is weak, a small amount (lower than the amount used during the growing season) can be applied after harvest to promote recovery and nutrient return and reserve, laying a foundation for the coming year. However, caution should be exercised to avoid overly stimulating the growth of autumn shoots and thereby reducing cold resistance.
Application method
Soil broadcasting (most commonly used) : Evenly spread the fertilizer near the drip line of the tree crown (the outer edge of the vertical projection of the tree crown) and slightly inward. This is the main distribution area of the absorbing roots. Avoid scattering it directly at the base of the tree trunk.
Application in furrows or acupoints
Circular trench application: Dig a trench about 20-30 cm deep and 20-30 cm wide along the drip line of the tree crown, sprinkle the fertilizer and cover it with soil.
Radial furrow application: Dig 4 to 8 radial furrows outward from the trunk (shallower inside and deeper outside to avoid damaging large roots), apply the fertilizer into the furrows and cover with soil.
Hole application: Dig multiple fertilizer holes evenly under the tree canopy (20-30 centimeters deep), apply the fertilizer and then cover it with soil.
Key techniques and precautions for scientific fertilization
1.Soil testing formula: The most accurate method! Through soil testing, the abundance or deficiency of soil nutrients can be understood. What is lacking should be supplemented to avoid waste and pollution.
2. Organic and inorganic combination: Using organic fertilizer as the base fertilizer and precise chemical fertilizer for top dressing is the golden rule for achieving high-yield, high-quality and sustainable apple cultivation.
3. Pay attention to applying base fertilizer in autumn: "Autumn fertilizer is gold!" Early, deep and adequate application of organic fertilizer is crucial for the growth and yield of trees in the coming year.
4. Skillful use of foliar fertilizers: For medium and trace elements (such as calcium, boron, zinc, iron, etc.) and rapid supplementation (such as potassium dihydrogen phosphate), foliar spraying is an efficient supplementation method, especially when the root system's absorption capacity is weak or the soil is severely fixed. Avoid spraying during periods of high temperature and strong light.
5. Balanced fertilization: Avoid excessive application of nitrogen fertilizer and pay attention to the balanced supply of nitrogen, phosphorus, potassium and trace elements. Excessive nitrogen fertilizer is one of the main reasons for the decline in quality.
6. Water Management: Water is indispensable for the dissolution of fertilizers and root absorption. After fertilization (especially top dressing), irrigate reasonably according to soil moisture conditions. Avoid flooding with water.
7. Fertilization based on tree age: Adjust the amount and proportion of fertilizer according to the tree age (young trees, trees in the peak fruit-bearing period, and senescent trees), tree vigor (vigorous or weak), and load capacity (the number of fruits borne).
