What fertilizer is good for apples after picking? What fertilizer is good for apple trees?

1. The importance of applying basal fertilizer: the effect of applying basal fertilizer in autumn is much better than fertilizing in winter or spring. Autumn basal fertilizer is golden, and this period of basal fertilizer has the following benefits:

1. The soil temperature of the main root distribution layer of apple is more suitable, the root growth is large, and the absorption function is more active, which is conducive to root absorption after fertilization. Clause.

Second, fertilization is conducive to improving the photosynthetic efficiency of leaves and increasing the accumulation of carbohydrates. Clause.

Third, the autumn application of organic fertilizer has enough time for the root system to absorb, run, and store in the tree, therefore, the autumn application of base fertilizer is an important part of the apple orchard fertilization system, but also the basis of fertilization throughout the year. There are two ways to apply basal fertilizer in autumn, the traditional ditching method, and the non-ditching method!

What fertilizer to use for apple autumn base fertilizer: At this time, the fertilization should fully supplement the nutrients needed by the fruit tree, and at the same time, it should also be able to promote soil improvement. After apple picking, in addition to high-quality organic fertilizer, you can also use polywuba mineral source potassium fulvic acid + polywuba water-soluble fertilizer to promote the formation of soil aggregate structure, improve soil moisture and water retention and air permeability, promote the growth of roots, and at the same time supplement the nitrogen, phosphorus and potassium nutrients required by fruit trees, quickly restore the tree potential, increase the accumulation of nutrients by fruit trees, promote the flower bud differentiation of fruit trees in the coming year, improve the flowering and fruiting rate, and achieve increased yield and quality.

In addition to autumn basal fertilizer, the following work should be done:

2. Watering the orchard: less rain in autumn is drier. Many orchards are now short of water, it is recommended that you immediately water the whole orchard, take advantage of the current ground temperature is still relatively high, and the weather is better.

Watering the orchard is conducive to the accumulation of nutrients in our tree body, and it is also conducive to the recovery of our tree. Quickly replenish the nutrients of the tree!

3. Orchard cleaning: Collect some fallen fruits, reflective films, fruit bags, stumps and leaves from the orchard in a timely manner, bury them or do harmless treatment.

4. Post-harvest pruning: In order to reduce nutrient consumption, promote the fullness of branches and buds, and facilitate the overwintering of the tree, appropriate pruning should be carried out after fruit picking.

Every year after the apple harvest, be sure to fertilize the orchard deeply, this fertilization is different from other times of fertilization, this fertilization is the annual base fertilizer of the orchard. The amount of application should be sufficient, the fertilizer elements should be complete, and the depth of tillage should be enough, and furrow application can be used, that is, ditching and fertilizing from the middle of the row spacing of fruit trees. In this way, the absorption of apple trees can be better, and all the waste, sundries, and debris in the orchard are cleared out of the orchard, and the fruit food bags, reflective films, sticky insect boards, dead branches, wild grasses, leaves, etc. are all removed from the garden, and all the waste is burned and buried.

In order to prevent insect eggs and diseases from overwintering in the garden.

Winter pruning is an important technical measure for orchard management. By thinning branches, light cutting, etc., the overly dense branches, steep branches on the back, upright branches, competing branches and too weak branches are thinned out in the chamber. Pruning off the long useless branches, diseased branches, weak branches, etc., is conducive to the accumulation of nutrients for fruit trees.

After winter pruning, the cut branches should also be cleared out of the garden.

Another very important link is to configure pesticides for apples, and paint them white within at least one meter from the main trunk of fruit trees on the ground, and paint the main trunk of good deeds white to prevent frost damage. Prevention of leaf miners, mites, leaf rollers, large green leafhoppers, cotton aphids, heart-eating insects, etc.; Prevent ring disease, rot disease and dry rot, etc. Enhance the nutrient storage of the tree, enhance the disease resistance of the tree, and make the orchard overwinter.

Some orchards with better conditions, after fertilizing and clearing the garden, can also be winter irrigated, which is the best way and link, which is very conducive to the accumulation of winter nutrition of fruit trees, if the conditions are not available, spring jars are necessary.

The above are the technical requirements for winter management in general orchards after apple harvest. Specific orchards should also be managed according to the situation of specific orchards.

For example, there are specific differences between the management of orchards for planting grass, the management of dwarf orchards, the management of new orchards, and the management of old orchards. However, the general principle is nothing more than the technical measures described above. The management of the winter orchard is very important, it is related to the fundamental problem of whether the next year can have a good yield and whether the quality can be high.

Farmyard manure is the first choice. There are cow dung, pig dung, sheep dung. Chemical fertilizers include Stanley fertilizer, compound fertilizer, urea, etc.

It is best to use organic fertilizer because it is rich in nutrients, including charcoal soil, coconut peat soil, humus soil, etc., which can promote the growth of plant rhizomes. Grass ash can also be used as fertilizer, which is nutritious.

After harvesting, potassium fulvic acid can be used to promote the formation of soil aggregate structure, improve soil air permeability, and promote the growth of roots.

Apple trees generally use farmhouse fertilizer, organic fertilizer, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and other fertilizers are better, among which farmhouse fertilizer and organic fertilizer can make apple trees grow better, nitrogen fertilizer, phosphate fertilizer and potassium fertilizer are conducive to increasing the sweetness of apple trees.

The buds of the apple tree have the advantage of the apex, in order to make the buds germinate smoothly, you can choose to apply fertilizer once before germination, and the fertilizer can choose farmhouse fertilizer and organic fertilizer, and the farmhouse fertilizer and organic fertilizer should be rotten to reduce the damage to the root system of the fruit tree.

2.Fertilization at the time of germination: When the apple tree sprouts, the fertilizer it needs mainly depends on the nutrients stored in the tree, but this is also the period when the root system grows and the branches and leaves begin to grow vigorously, and the fertilization at this time is mainly to improve the quality and growth of the bud.

3.Top dressing during flowering: Top dressing is generally carried out during the flowering period of apple trees, which is to promote the fruiting and vegetative growth of apple trees.

4.Fertilization at the fruit expansion stage: The fruit expansion stage of apple trees needs to be supplemented with an appropriate amount of nitrogen, phosphorus and potassium fertilizers, which is to promote the sugar and color enhancement of fruits and organ differentiation, and the commonly used fertilizers are potassium dihydrogen phosphate or potassium phosphate.

5.Fertilization at maturity: About a month before the fruit of the apple tree matures, phosphorus and potassium fertilizer should be appropriately applied, and calcium, boron and other fertilizers should be used to promote the maturity and nutrient accumulation of apple trees.

6.Post-harvest fertilization: After the harvest of the apple tree, a timely fertilization should be carried out, mainly to help the tree to replenish the nutrients lost due to harvesting and restore the tree's vigor.

Fertilization method: 1Radial furrow fertilization method: dig a trench under the apple canopy according to the horizontal root distribution, generally start digging the first circle from two meters away from the trunk, and then expand outward, the width of the trench should be gradually expanded, and the depth should be kept at about 20-30 cm.

2.Hole casting: Dig near the area where the absorbing roots are distributed, to a depth of about 20-30 cm.

3.Foliar spray: Foliar spray can spray fertilizer directly on the surface of the leaves, but care needs to be taken to control the concentration and avoid leaf burning.

In short, the fertilization of apple trees should be analyzed according to the actual situation, and the appropriate fertilizer type and fertilization method should be selected to help improve the yield and quality.

The favorite fertilizer for apple trees is bio-organic fertilizer. Secondly, feed nitrogen, phosphorus and potassium water-soluble fertilizer and compound fertilizer. Then there is micro-fertilizer, which is also indispensable, calcium, magnesium, sulfur, iron, zinc, boron ......In short, fruit trees are mainly bio-fertilizer, supplemented by water-soluble fertilizer, compound fertilizer and micro-fertilizer.

Fertilize wisely.

Apple tree. Generally, it is better to use farmhouse fertilizer, organic fertilizer, nitrogen fertilizer, phosphate fertilizer, potassium fertilizer and other fertilizers. The capillary roots of the apple tree are its main organs for absorbing nutrients, and the absorption of fertilizer is mainly completed by the root hairs in the root system, so fertilization in the concentrated distribution area of the root system is one of the keys to improve fertilizer efficiency.

In early April, pre-flowering or germination fertilizer is applied to apple trees. In mid-May, post-flowering fertilizer is applied. From the end of May to the beginning of June, the apple trees should be fertilized with flower bud differentiation and young fruit expansion.

Basal fertilizer should be applied in early September. When fertilizing, it is necessary to apply the depth and shallowness according to the depth of the root distribution. Apply organic fertilizer at a depth of 40 to 60 cm.

Foliar fertilizer should also be applied according to the growth of the fruit tree.

1. The best time to fertilize apple trees.

The best time and method of fertilizing apple trees and the formulation.

Apple trees should be fertilized with pre-flowering or germination fertilizer, usually in early April. In mid-May, post-flowering fertilizer is applied. These two fertilization applications can promote budding and flowering of fruit trees, prevent the defertilization of fruit trees due to nutrient consumption, improve fruit setting rate, and promote the growth of new branches.

The best time and method of fertilizing apple trees and the formulation.

From the end of May to the beginning of June, flower bud differentiation and young fruit expansion fertilizer should be applied to apple trees to meet the needs of apple expansion, branch bud growth and flower bud differentiation. In early September, basal fertilizer should be applied, basal fertilizer should be mainly farmhouse fertilizer, and phosphate fertilizer should be applied according to the total amount of the year.

2. Fertilization methods and formulas for apple trees.

The best time and method of fertilizing apple trees and the formulation.

When fertilizing apple trees, if the root system is deeply distributed, it should be applied appropriately deeply, and if not, it should be applied shallowly. The decomposition of organic fertilizer is slow, the fertilizer supply period is long, and it is suitable for deep application, and the mobility of chemical fertilizer is large, so it can be applied shallowly. If organic fertilizer is applied, the depth should be between 40 and 60 cm.

At the same time, fertilization should be applied a little further away from the crown projection.

The best time and method of fertilizing apple trees and the formulation.

Foliar fertilizer can also be applied according to the growth of the fruit tree. If the leaves of the fruit tree are yellowish, nitrogen fertilizer should be applied, and some ferric citrate and phosphorus and potassium fertilizer should be applied appropriately. If the internode between the branches is too long, phosphorus and potassium fertilizer should be sprayed.

The varieties suitable for plant spraying include urea, potassium dihydrogen phosphate, potassium sulfate, etc.

Farm fertilizer, and nitrogen, phosphorus and potassium fertilizer, compound fertilizer, slow-release fertilizer, can be in apples, potassium fertilizer can improve the sweetness of fruits.

After strawberry fruit picking, in order to make up for the nutrient consumption caused by the fruit, enhance the growth potential, and promote the stolons of the strong stolon, it should be topdressed in time. Fast-acting nitrogen fertilizer can be applied, and a small amount of phosphorus and potassium fertilizer can be added. Strawberry cultivation is different from other crops in that it requires the right amount of nitrogen fertilizer.

Because the main role of nitrogen fertilizer is to promote the formation of a large number of leaves and creeping stems, enhance vegetative growth, and increase the size of fruits.

If too much nitrogen fertilizer is applied, it is easy to cause strawberry seedlings to grow, increase diseases, and weaken the flavor of fruits. Phosphate fertilizer mainly promotes flower bud differentiation and fruit setting rate, while potassium fertilizer can promote fruit ripening, increase fruit sugar content and improve fruit quality. Therefore, the fertilization of strawberries should be suitable for nitrogen, phosphorus and potassium.

Summary. Hello, I have helped you find the result; After apple fruit set, apply grams of diammonium phosphate or urea per fruit, and then apply grams of potassium sulfate or magnesium sulfate per fruit during the rapid growth period of the fruit, and organic fertilizers can also be used. When fertilizing, care should be taken to avoid excessive application of fertilizer, so as not to cause damage to the apple tree.

Apple trees need to be fertilized after fruit setting to ensure the quality and yield of the fruit.

Come on. Hello, I have helped you find the result; After the apple is set on the fruit, apply diammonium phosphate or urea to each fruit, and then apply potassium sulfate or magnesium sulfate to each fruit during the rapid growth period of the fruit, and organic fertilizers can also be used. When fertilizing, care should be taken to avoid excessive application of fertilizer, so as not to cause damage to the apple tree.

After fruit set, apple trees need to be fertilized to ensure the quality and yield of the fruit.

Is that still <> you?

Hello dear, what do you want.

Hello dear, do you want to know what brand of fertilizer you need?

Hello, I have helped you find the result; Fertilizer 1, gibberellin: spraying 50mg L of gibberellin on varieties such as Guoguang and Marshal in the flowering period of apple bush branches can improve the fruit setting rate. 2. Triacosanol:

For some apple varieties with poor coloration, such as Changfu Eggplant Ruler No. 2 and Beidou, the spraying of triasanol during the flowering period can improve the fruit setting rate and promote the later coloring of the fruit. 3. P-chlorophenoxyacetic acid: spraying 20mg L p-chlorophenoxyacetic acid + urea at the apple flowering stage can improve the fruit setting rate of apple trees.

Apple tree fertilization time.

Generally, there are five main periods of apple tree fertilization, namely the budding stage, after flowering, the second fruit expansion period, the fruit nutrient transformation period and the autumn basal fertilizer.

What fertilizer to apply to apple trees.

When fertilizing apple trees, nitrogen fertilizer is generally appropriate. Appropriate application of nitrogen fertilizer within a certain range can increase the number of branches and leaves of trees, enhance tree vigor and increase yield. In addition, phosphorus and potassium fertilizers should be appropriately supplemented for apples, which can not only increase the yield of apples, but also promote the growth and development of plant roots, and promote the extension of roots to deep soil, so as to improve the drought resistance of fruit trees.

How to fertilize apple trees.

When fertilizing an apple tree, it can be fertilized through the roots, which are the main organs of the fruit tree to absorb nutrients. Fertilizing the roots can improve the fertilizer. In addition, fertilizer can be sprayed on the leaves of the apple tree.

If the tree grows weakly and the leaves turn yellow or light yellow, it means that the plant is deficient in oxygen and iron, and nitrogen fertilizer should be sprayed to relieve the symptoms.

Precautions for fertilizing apple trees.

When fertilizing apple trees, be careful not to apply too much fertilizer to avoid fertilizer damage. In addition, the stomata on the back of the leaves of the plant are large, and the fertilizer is easily absorbed. Therefore, when spraying fertilizer, the back of the leaf should be the main one, so that some of the fertilizer will slide to the bottom of the leaf.

How to fertilize apples after bagging.

During the planting process, the apple tree will enter the peak growth and development period in the month. The apple tree will enter the fruit expansion stage after bagging, and it needs to be properly applied with phosphate or potassium fertilizer.

When fertilizing apple trees, it is best to dig a shallow radial trench in the ground and sprinkle some phosphorus and potassium fertilizer evenly in the trench. In order to better grow apples, on the basis of proper fertilization, fertilizers such as Bika silica-soluble potassium dihydrogen phosphate can also be properly sprayed on the leaves, and evenly sprinkled on them as foliar fertilizer.

The use of phosphorus and potassium fertilizer after apple bagging can promote the photosynthesis of apple trees, and can also improve the cold, drought and disease resistance of apple trees, which is very helpful for promoting apple expansion, uniform coloring of fruits, and improving quality.

In order to improve the yield of apples, many fruit farmers will habitually use a large amount of high-nitrogen compound fertilizer for it after bagging, but this fertilization is easy to lead to rough peel, slow coloring, poor quality and poor taste. Therefore, it is not recommended to use this fertilization method, when fertilizing, it is best to choose to use phosphorus and potassium fertilizer for it, and the fertilization method is best to choose furrow application.
