What fertilizer is used for fruit trees? What fertilizer is needed for fruit trees

Commonly used chemical fertilizers for fruit trees are mainly urea, diammonium phosphate, superphosphate, potassium sulfate, etc. Because chemical fertilizers can only play the role of supplementing nutrients and cannot improve soil structure, the long-term use of chemical fertilizers will cause soil compaction and lose the balance between soil nutrients. Therefore, when fruit trees use chemical fertilizers, they should be used in conjunction with organic fertilizers, that is, soil miscellaneous fertilizers are the mainstay, chemical fertilizers are used as top dressing, and fertilizer is supplemented during the critical period of growth and development.

Immediate results are obtained. When fruit trees have symptoms of nutrient deficiency due to the lack of certain elements, they should be supplemented in time by topdressing chemical fertilizer or topdressing outside roots. According to the growth changes in the annual cycle of fruit trees, chemical fertilizers are generally applied 3 to 5 times.

1) Two weeks before flowering: Fast-acting nitrogen fertilizers, such as urea, can promote growth, enhance tree strength, and improve fruit setting rate.

2) After flowering: also chase fast-acting nitrogen fertilizer to supplement the nutrients consumed by flowering and fruit setting, reduce fruit drop and ensure the vigorous growth of new shoots.

3) After physiological fruit drop: the topdressing of available nitrogen, phosphorus and potassium promotes root growth, improves leaf function, and is conducive to flower bud differentiation and fruit expansion.

4) Long-term topdressing in autumn: mainly available nitrogen, combined with phosphorus and potassium fertilizers, promote root growth, improve leaf photosynthetic capacity, ensure fruit expansion in the later stage, and increase tree storage nutrients.

5) Post-harvest top dressing: mainly available nitrogen fertilizer, combined with potassium fertilizer. It can improve the photosynthetic function of leaves, prolong the life of leaves, enhance the nutritional level of trees, promote the growth of roots in autumn, and enrich flower buds.

What fertilizer is good for fertilizing fruit trees.

Organic fertilizer is the best and nutritious. Now the fruit trees are managed by the method of extracting raw grass, and the soil is not loosened.

Fruit tree bottom fertilizer can use organic fertilizer, bacterial fertilizer, water-soluble fertilizer in the middle stage, and Peng fruit coloring fertilizer in the later stage.

Hello dear: 1. It is better to apply urea, diammonium phosphate, superphosphate, potassium sulfate, organic fertilizer, soil miscellaneous fertilizer and other fertilizers for planting fruit trees. Chemical fertilizers can only play a role in supplementing nutrients for fruit trees, but cannot improve the structure of the soil, if only chemical fertilizers are used for a long time, it will cause the phenomenon of soil compaction, so that the nutrients in the soil are out of balance.

2. When using chemical fertilizer for fruit trees, it should be applied in conjunction with organic fertilizer or soil miscellaneous fertilizer, that is, organic fertilizer or soil miscellaneous fertilizer is the main fertilizer, supplemented by chemical fertilizer (chemical fertilizer can be applied as top dressing, such as fertilizer supplementation during the critical period of growth and development of fruit trees), so that it can have an immediate effect. 3. When the fruit tree has the symptoms of nutrient deficiency, it can be supplemented by more topdressing fertilizer or topdressing outside the roots, but the number of topdressing should be determined according to the growth changes of the fruit tree in the annual cycle, and under normal circumstances, 3-5 times can be topdressed.

Fruit trees can generally use nitrogen fertilizer, potassium fertilizer, phosphate fertilizer, farm fertilizer or compound fertilizer. Chemical fertilizers can only play a role in supplementing nutrients for plants, and long-term use of chemical fertilizers will make the nutrients in the soil out of balance, so chemical fertilizers should be applied together with organic fertilizers.

How to prevent frostbite from fruit trees.

Before the arrival of winter, wrapping the trunk with a straw rope can prevent the cold air from harming the fruit trees to a certain extent.

When the weather is cold, seal the rhizomes of fruit trees tightly with a mound of soil to prevent cold air from damaging the rhizomes.

Painting the trunk of a fruit tree white can mitigate damage to the bark due to sudden temperature changes, and it can also insulate the trunk to a certain extent.

Overview of fertilization of fruit trees.

Fruit trees refer to trees with edible fruits, such as apple trees, pear trees, citrus trees, apricot trees, peach trees, etc. Many people think that only apple trees belong to fruit trees, but this is actually a misconception about fruit trees. In general, if you want to fertilize fruit trees, you can apply farmyard fertilizer, organic fertilizer, or fermented farmyard fertilizer.

These are high-quality basal fertilizers for fruit trees. These fertilizers have long fertilizer effect, mild fertilizer effect, and comprehensive nutrients, which can provide sufficient nutrients for the growth of fruit trees.

What fertilizer is good for fruit trees.

In general, different fertilizers need to be applied to fruit trees at different stages, organic and inorganic fertilizers need to be applied 5-10 days before the start of spring. The combination of the two promotes the germination of plants. The specific fertilizers applied are manure, urea, superphosphate, potassium sulfate, zinc sulfate, boron fertilizer, and ferrous sulfate.

After the fruit tree germinates, if the branches grow weakly or germinate unevenly, urea and superphosphoric acid such as cavity calcium and potassium sulfate should be applied to fertilize and strengthen the branches.

How to fertilize fruit trees.

The method of fertilizing fruit trees is relatively simple. Dig a trench directly on either side of the vine, apply the prepared organic fertilizer, then fill it and water it. Be careful when ditching and fertilizing fruit trees.

Do not plow the furrow in the same place every time you apply fertilizer, as this will damage the roots of the previous year's new girders. 1.Fertilization in the spring.

Spring fertilization is generally done around April. At this time, nitrogen is one of the nutrients required by fruit trees, and nitrogen-containing fertilizers need to be applied to plants in time to promote their vigorous growth. 2.

Summer fertilization. Fertilization is generally carried out in June-July in the summer. At this time, the demand for phosphorus in fruit trees is relatively large, and they need to be applied with phosphorus-containing fertilizers to promote fruit expansion.

3.Autumn fertilization is more suitable for mid-October fertilization. At this time, the fruit trees need a certain amount of potassium, so it is necessary to apply them a fertilizer containing potassium and give the plant enough nutrients to resume their growth.

4.Winter fertilization is more suitable for fertilization in November-December in winter. The fertilizer is mainly applied in combination with well-rotted human manure or urea, plant ash and other fast-acting fertilizers.

Pay attention to the key points when fertilizing fruit trees.

1.When fertilizing fruit trees, if you want to prevent fertilizer damage and root burning, you should not use too thick fertilizer when fertilizing, and the amount of fertilizer should not be too much. 2.

In order to prevent the yellowing of fruit tree leaves, it is necessary to combine inorganic fertilizer with organic fertilizer, chemical fertilizer and microbial fertilizer for fertilization, so as to achieve full nutrient fertilization and avoid leaf yellowing. 3.Fruit trees are light-protected plants and have high requirements for light.

Therefore, it is important to ensure sufficient light after fertilization to promote the growth and development of the vines, as well as to improve yield and quality.
