How to top fertilize apple trees in July What is the best fertilizer to apply to apple trees in July

The peak of fruit growth occurs from mid-to-late June to early to mid-July.

Top dressing during the rapid expansion of fruits: This topdressing is mainly to accelerate the rapid expansion of fruits and improve the expansion rate of fruit cells. To increase yields, overcome the body of the tree"Big and small years", which plays an important role in promoting flower bud differentiation.

This period is carried out on the basis of the second top dressing, after physiological fruit drop. The type of fertilizer is still mainly nitrogen, and the combination of phosphorus and potassium is the most ideal.

According to the survey, the rapid expansion period (peak growth) of apple fruit varies depending on the region and variety. According to the survey conducted by Tianjin Forestry and Fruit Research Institute, the peak growth of Marshal short-branched varieties and Golden Crown varieties occurred from mid-to-late June to early to mid-July. That is, after mid-June, the fruit will enter the period of rapid expansion.

In production practice, top dressing should master the principle of top dressing and fertilization according to the place, the tree has strength and weakness, and the demand for nutrients is also different depending on the amount of fruit. The amount of fruit is large, and weak trees should be eaten"Partial rice", to give more fertilizer. For strong trees, trees with few flowers and fruits or young and vigorous trees that do not bear fruit, in order to slow down the growth of branches and leaves, promote the formation of short branches and the differentiation of flower buds, top dressing should be done after the new shoots stop growing, and the amount should be small.

Right"Big year"Trees should be increased in the middle and late stages of top dressing. "Little years"Trees should focus on top dressing before and after germination. It should be noted that the middle and late topdressing of fruit trees should not be too late.

The number should not be too much. In order to avoid causing the growth of new shoots in late autumn, reduce the nutrient accumulation level and cold resistance of the tree. It also affects the coloration and fruit quality of the variety.

Depending on the topdressing, the soil conditions of the orchard are different, and the topdressing should also be treated differently. The fertilizer and water retention capacity of the sandy land is poor, so it is necessary to chase less frequently, and do not water a lot of water after the top dressing, so as to cause water and fertilizer leakage in tin. Saline-alkali land, the available phosphorus content in the soil is low, and phosphorus fertilizer should be added (soil application or extra-root topdressing) when topdressing.

In mid to late July, the topdressing of fruit expansion fertilizer is conducive to promoting the growth of new roots, improving leaf function, increasing single fruit weight, increasing grade fruit rate and yield, enriching flower buds and tree nutrient accumulation, improving tree resistance, and laying a good foundation for the high yield and quality of the current year and the bumper harvest of the next year. Generally, about 50 kg of fast-acting compound fertilizer (high nitrogen and high potassium compound fertilizer) is applied per mu, which is conducive to promoting fruit expansion, and topdressing phosphorus and potassium fertilizer can improve fruit hardness and sugar content, and promote fruit coloring.

Summary. Good afternoon, I'm glad to answer for you, this topdressing is mainly to accelerate the rapid expansion of the fruit and improve the expansion rate of fruit cells.

How do trace elements need to be supplemented, and is there a fertilization plan for shellfish?

Nitrogen-based, with phosphorus and potassium compound fertilizer is the most ideal.

Apple trees are sprayed with pesticides in July, what insects need to be controlled.

1.Prevention and control of coarse or rotten objects Early defoliation, anthracnose, red spiders, golden-striped moths, heart-eating insects, leaf-curling moths, etc. 2.

The focus of the prevention and control work in July is the high temperature season, when the leaf is 7 8 hawthorn leaf mite adult mites, the mass fraction of spraying, the same below) avermectin 2000 3000 times liquid or 15% pyridoxine rock leakage 3000 times liquid control;

Approximately what time period the pesticide is applied.

Shady weather.

Supplement trace elements: At this time, fertilizers containing trace elements, such as fertilizers rich in zinc, iron and other elements, can be used to help apple trees grow healthily. 2.

Top dressing: Compound fertilizers of nitrogen, phosphorus, potassium and other elements can be used for top dressing, **nutrients required by apple trees. According to the actual situation of the apple tree, it can be fertilized in an appropriate amount.

3.Organic fertilizers: Organic fertilizers, such as well-rotted compost or chicken manure, are also a good option to provide the organic matter and nutrients that plants need.

Dear friends, please pay attention to the actual condition of the trees and avoid over-fertilising or using improper fertilizers to avoid damage to the apple trees. It is best to refer to the advice of professionals or gardening books before fertilizing to ensure the correct fertilization.

What fertilizer is good for apple trees in August.

Dear, I'm glad to answer for the stove to send you, if you fertilize the apple tree in July, you can consider the following points:1Supplementation of trace elements:

At this time, you can use fertilizers containing trace elements, such as fertilizers rich in zinc, iron and other elements, to help apple trees grow healthily. 2.Top dressing:

You can use a compound fertilizer of nitrogen, phosphorus, potassium and other elements for top dressing, ** nutrients needed for apple trees. According to the actual situation of the apple tree, it can be fertilized in an appropriate amount. 3.

Organic fertilizers: Organic fertilizers, such as well-rotted compost or chicken manure, are also a good option to provide the organic matter and nutrients that plants need. Dear friends, please pay attention to the actual condition of the trees and avoid over-fertilising or using improper fertilizers to avoid damage to the apple trees.

August is the ripening period of apple trees, when pest control and fruit protection should be carried out. When it comes to fertilization, you can consider the following:1

Keep the soil moist: During the ripening period, apple trees need enough water to maintain fruit quality and growth. Therefore, it is very important to ensure that the soil is moist and can be watered in the right amount to meet the water requirements.

2.Potassium: Potassium plays an important role in the ripening and quality of the fruit.

Top dressing can be done using fertilizers containing high potassium content to increase the sugar content and aroma of the fruit. 3.Organic fertilizers:

Organic fertilizers can provide the nutrients and nutrients that plants need, and they are also beneficial for soil improvement. It can be applied using well-rotted compost or organic fertilizers such as chicken manure. Pay attention to the actual situation of the trees, and determine the appropriate fertilizer type and amount according to the soil conditions and the growing environment of the apple tree.

It is best to refer to the advice of a professional or gardening book before fertilising to ensure that the fertiliser is being carried correctly.

The varieties of apples that naturally ripen in June are not certain, because of the rapid development of pesticides and fertilizers, all kinds of off-season vegetables and fruits, all of which are greenhouse crops, and now the ripening agent is also very developed, which can make apples speed up the ripening speed back to the bridge, so that they can be listed in advance, and various varieties are possible. Leakage is fierce.

Generally speaking, the fertilization period should pay attention to the autumn application of basal fertilizer, 60% 80% of the phosphate fertilizer should be applied in the form of basal fertilizer, with a small amount of nitrogen fertilizer and potassium fertilizer, 60% of nitrogen fertilizer in spring, the summer young fruit expansion period and flower bud differentiation period to apply an appropriate amount of nitrogen, phosphorus and potassium fertilizer, most of the potassium fertilizer should be applied 20 days before the young fruit expansion period and fruit coloring, you can use the imported water-soluble fertilizer with fast dissolution and high utilization rate.

The demand for nitrogen fertilizer is less than that of general varieties, and the demand for phosphorus and potassium fertilizer is relatively large. The ratio of nitrogen, phosphorus and potassium in the fruiting stage is generally 1:1

During the fruit expansion period, nitrogen fertilizer should not be applied partially, but phosphorus and potassium fertilizer should be increased. In addition, potassium dihydrogen phosphate is also needed to ensure the normal growth of red Fuji apple trees. The survey showed that the application of potassium fertilizer alone in August resulted in good fruit coloring, and the size of the year was not significant.

Summary. Hello, dear, I am glad to answer for you: apple trees are balanced fertilizers in June.

Hello, dear, I am glad to answer for you: apple trees are balanced fertilizers in June.

If you are fertilizing your apple trees in June, you can consider using a balanced fertilizer and choose a balanced plant fertilizer, such as 10-10-10 or 14-14-14, which contains the right amount of nitrogen, phosphorus and potassium to provide the main nutrients needed by the apple tree.

May I. Dear, yes, thank you for your support, I wish you all the best!

When fertilizing apple trees in June, phosphorus fertilizer is the main front, at this time it is the young fruit expansion period of the plant, and the application of phosphorus fertilizer can promote the growth of fruits, at this time, it is necessary to pay attention to reducing the amount of nitrogen fertilizer and irrigation to promote the formation of flower buds, when fertilizing apple trees, you can dig a ring ditch or tic-tac-toe ditch under the crown projection, and then put the fertilizer into the ditch and cover the soil to bury.

Apple trees in June fertilization to phosphate fertilizer, at this time for the young fruit expansion period of the plant, the application of phosphate fertilizer can promote the fruit of the strong, and wait until July to August, and then apply potassium fertilizer for it, can play a significant role in increasing yield.

When fertilizing apple trees, you can dig a ring ditch or tic-tac-toe ditch with a width and depth of 50 cm under the crown projection, then put the fertilizer into the ditch, cover it with garden soil, and then grind it with a watering belt to fully integrate the soil and fertilizer.

June is the critical period for apple tree flower buds to begin physiological differentiation, at this time, it is necessary to reduce the amount of nitrogen fertilizer and irrigation, so that the soil moisture is controlled at about 60% of the field drainage, so as to promote the formation of flower buds, and the fertilizer should be fully diluted before fertilization to avoid burning roots with thick fertilizer.

After the budding of the apple tree, it is necessary to remove the weak fruit and diseased fruit in time to promote the formation of strong fruit, and after the beginning of spring, in order to control all kinds of red spiders, scale insects and overwintering insect eggs, it is necessary to spray it every 7-10 days with stone sulfur mixture.

Hello, here is the best choice of compound fertilizer or organic fertilizer (such as organic cow dung or organic fishmeal, etc.) for fertilization in June. Compound fertilizer can provide a variety of nutrients, which can provide better nutritional supplements for apple trees and stimulate the growth of fruit trees. In addition to promoting the growth of plants, reducing soil pH value, and reducing the failure of sharp nitrogen, organic fertilizer can also provide common nutrients and promote the growth and development of fruit trees. When applying fertilizer, we should also consider the terrain, climate, soil type, branchage, water, etc., and pay attention to the fertilizer in the soil, and mix the fertilizer and the soil evenly to ensure the uniform application of fertilizer.

In addition, when fertilizing in June, in order to ensure the nutritional balance, nutrients such as phosphate fertilizer and potassium fertilizer should also be supplemented to help the fruit trees mature normally and improve their quality.
