What kind of fertilizer is good for apple trees
Sharing small green plant maintenance tips on what kind of fertilizer is good for apple trees, next, the editor will introduce.
What kind of fertilizer is good for apple trees
When fertilizing apple trees, you can apply farmyard manure, organic fertilizer, and maturely fermented farmyard manure, which are good base fertilizers for apple trees. These fertilizers have a long-lasting effect, a gentle effect, and comprehensive nutrients, which can improve the physical and chemical properties of the soil and provide a high-quality environment for fruit growth. After the beginning of spring, within 5-10 days, you can apply germination fertilizer, and the combination of organic and inorganic fertilizers can help the apple trees grow vigorously.
What kind of fertilizer to apply to apple trees
When fertilizing apple trees, you can apply farmyard manure, organic fertilizer, and maturely fermented farmyard manure, which are good base fertilizers for apple trees. These fertilizers have a long-lasting effect, a gentle effect, and comprehensive nutrients, which can improve the physical and chemical properties of the soil and provide a high-quality environment for fruit growth.
1. Apple trees need to apply germination fertilizer within 5-10 days after the beginning of spring. Combine organic and inorganic fertilizers and apply them in a fertilization trench 30-40 cm away from the main stem, 10-15 cm deep.
2. In April, apple trees should apply the first fruit-strengthening fertilizer, applying 30 kg of urea, 20 kg of sulfate potassium, and 25 kg of common superphosphate per mu, followed by applying fruit-strengthening fertilizer every 20 days.
How to fertilize apple trees
Dig trenches on both sides of the apple trees, apply the prepared organic fertilizer, and then cover it up. When digging the trenches, do not dig in the same place each time. Start from the direction away from the base of the apple tree, closely adjacent to the place where the trench was dug last year, and expand the trench outward. After several years, the entire fruit garden can be fertilized once.
Apple trees need to be fertilized in April, during spring. Applying more nitrogen fertilizer can promote the growth of fruit trees, help them absorb enough nutrients, and produce more flowers.
Apple trees can be fertilized in June-July during summer. The fruit's need for phosphorus starts from the injury flow period, peaks during the vigorous growth period of new shoots and fruit expansion, then decreases, and absorption increases again after harvest.
Fertilizing apple trees in mid-October during autumn is good. Fruits need a certain amount of potassium, and the absorption of potassium is relatively stable throughout the annual growth cycle, but there is a significant increase in potassium absorption during fruit expansion.
Fertilizing apple trees from November to December during winter is suitable. Top-dressing should mainly consist of decomposed human waste, plant ash, urea, and other fast-acting fertilizers. The amount of fertilizer applied at this time accounts for 20%-30% of the annual fertilizer application.
Key points to note when fertilizing apple trees
1. Prevent fertilizer burns: When fertilizing apple trees, it is necessary to apply a large amount of water, then immediately drain it, spray a harmless foliar fertilizer to promote new roots, and spray again three days later.
2. Prevent yellowing leaves: To prevent the leaves of apple trees from turning yellow, combine macroelements with microelements, and combine inorganic fertilizers with organic fertilizers to achieve comprehensive nutrition.
3. Light requirements: Apple trees are light-loving plants with high light requirements. After fertilizing, it is appropriate to expose the plants to some sunlight to promote rapid absorption and growth.
