What is the sour deficiency in grapes? When to add what fertilizer?

What fertilizer to use for planting grapes, what fertilizer to use, planting grapes with 3000 pounds of farm fertilizer per acre of land is the best, if there is no farm fertilizer, only use compound fertilizer 300 pounds per acre. Generally, the fertilization is completed before the beginning of spring, and the fertilizer is sprinkled on the ground 1 to 4 feet away from the vines, and then turned down 3 to 4 inches.

It is recommended to use Black Tiger Bottom Fertilizer + Black Tiger Compound Microbial Fertilizer to increase the content of soil organic matter and effective nutrients, adjust soil pH value in both directions, improve the buffering capacity of soil to acidification, improve soil structure, and can fertilize the soil, supplement the trace elements in amino acid chelation, improve the grape root environment through active microbial hailstorm, raise roots, promote source preparation, quickly restore tree nutrients, and scientifically supplement nitrogen, phosphorus and potassium, The active microorganisms in the black tiger compound microbial fertilizer work together

Organic fertilizer: apply organic fertilizer such as well-rotted soybean cake fertilizer, crop straw, and well-rotted human and animal manure. Compound fertilizer:

In autumn, the grapes should be supplemented with compound fertilizer to provide sufficient nutrients for the plants. Fertilization method: Dig a shallow fertilization ditch forty to fifty centimeters away from the grapes.

Daily management: Pruning and shaping the plants regularly.

1. Organic fertilizer

When fertilizing grapes in autumn, it is necessary to choose to apply organic fertilizer-based fertilizer, generally choose well-rotted soybean cake fertilizer, crop straw, rotted human and animal manure, etc., and then apply 400 to 500 kg of well-rotted human and animal manure per mu, or use well-rotted soybean cake fertilizer.

2. Compound fertilizer

Grapes should also be supplemented with nitrogen, phosphorus and potassium compound fertilizers in autumn, especially phosphorus and potassium fertilizers, usually 40 to 50 kg of nitrogen, phosphorus and potassium compound fertilizers, 80 to 100 kg of superphosphate or calcium-magnesium phosphate fertilizer, and 25 to 30 kg of potassium sulfate per mu, which can not only provide sufficient nutrients for plants, but also increase the resistance of grapes.

3. Fertilization method

When fertilizing grapes, it is necessary to dig a shallow annular trench with a depth of 25 to 30 cm from the plant, and then pour the fertilizer evenly into the ditch, cover the soil, and water it once to promote better absorption of water and nutrients by the root system.

4. Daily management

In the process of maintaining grape vines in autumn, it is necessary to prune the plants, cut off the branches that are too dense, too long and too weak to reduce nutrient consumption, and at the same time check the growth of the branches on the main stem, and then cut off the branches that are weak and affect the appearance, which is conducive to the growth of the main stem branches.

<> grape ripening period is suitable for organic fertilizers such as manure, compost, pond mud, etc. 3000-4000 kg of organic fertilizer should be applied per mu of vineyard, and 10-15 kg of potassium fertilizer or 70-100 kg of compound fertilizer should be applied per mu. Apply chemical fertilizer first and then apply organic fertilizer, it is better to apply radial deep application, and cover the soil after fertilization, and the depth of covering soil is 20-25 cm.

After the fertilization is completed, pay attention to proper irrigation, which is conducive to the better fertilizer effect of the fertilizer.

1. What fertilizer should be used during the ripening period of grapes

1. Fertilization fertilizer during the grape maturity period is better with organic fertilizer such as manure, compost, pond mud, etc. At the same time, it is mixed with potassium cavity fertilizer, compound fertilizer and other fast-acting fertilizers. 3000-4000 kg of organic fertilizer per mu of vineyard is applied, mixed with 10-15 kg of potash or 70-100 kg of compound fertilizer.

It is better to apply radial deep application, first apply chemical fertilizer and then apply organic matter fertilizer, and then cover the soil, the depth of the soil cover is 20-25 cm, and pay attention to the timely irrigation after fertilizing and covering the soil.

2. After the grape is harvested, in order to quickly recover from the injury, survive the winter safely, and not affect the products of the next year, some nitrogen fertilizer and phosphate fertilizer can be applied to promote the recovery of the injury and the development of the root system. It can be applied up to 1 month after harvest, the earlier the better.

3. Grapes should be harvested at the right time when they are ripe. The ripe grapes have a bright skin, and when the rainbow flesh is transparent, there is a thick layer of powder, which has its inherent flavor when eaten, and the seeds are brown. If you pick too early, the acid will be too high, which will affect the quality, and if you pick too late, the fruit will taste good and will not be resistant to storage and transportation.

Second, what fertilizer to use if the grapes are not sweet

1. Grapes are not sweet with urea, potassium sulfate, calcium and other fertilizers. Grapes are not sweet should be sugar-added coloring fertilizer, after a small amount of fruit coloring, apply sugar-enhancing coloring fertilizer, generally 30 kg of urea, 25 kg of general calcium, 30-35 kg of potassium sulfate. The specific amount of fertilizer should be adapted to the physical and chemical properties of the soil.

Generally, sandy and mountainous areas are barren and thin, and the amount of fertilizer should be large; For flat land with fertile soil, the amount of fertilizer can be appropriately reduced.

2. The more fertilization of grapes, the better, according to the characteristics of the grapes, the amount of application is enough, not too much. Excessive application of fertilizer can lead to a decrease in shoot length, fruit set and fruiting per hectare, which in turn affects the yield of the grapes.

3. Fertilization should be combined with hole application and foliar fertilizer, and different fertilizers in different growth periods should be used in appropriate fertilization methods to achieve effective use of fertilizers.

Hello grape base fertilizer fertilization time: grape base fertilizer is generally applied after grape fruit picking, at this time the base fertilizer is applied in time, which is conducive to restoring tree potential, prolonging leaf life, promoting leaf photosynthesis, improving the degree of lignification of branches, and increasing tree nutrient storage. Generally speaking, the earlier the grape autumn fertilizer is applied, the better, but it is necessary to adapt measures to local conditions, scientific management, according to local climatic conditions, too high or too low temperature is not conducive to root growth.

2.It is recommended to use black tiger bottom fertilizer + black tiger compound microbial fertilizer to increase the content of soil organic matter and effective nutrients, adjust the soil pH value in both directions, improve the buffer capacity of the soil against acidification, improve the soil structure, and can fertilize the soil, supplement the trace elements in amino acid chelation, improve the grape root environment through active microorganisms, raise roots, promote roots, quickly restore tree nutrients, and scientifically supplement nitrogen, phosphorus and potassium. The active microorganisms in the Black Tiger Complex Microbial Bacteria Fertilizer Hongshou work together to make the grapes grow healthier.

<> the grapes enter the young fruiting stage, nitrogen, phosphate, potassium and other chemical fertilizers can be applied, and an appropriate amount of organic fertilizer can also be applied. When the grape is in the soybean size, it is the critical period of fertilizer and water for fruit development, at this time, the top dressing is generally based on nitrogen fertilizer, and at the same time, it is necessary to cooperate with the application of phosphate fertilizer and potassium fertilizer, generally 30 kg of urea, 20 kg of superphosphate and 20 kg of potassium sulfate can be applied per mu. Notes:

The top dressing work must be combined with the irrigation and the irrigation must be ensured to be thoroughly irrigated.

Overwintering fertilizer: Traditionally, it has been applied during the dormant period of the grapes. Now it is recommended to apply in the month, after the grape is harvested, it is also applied during the growth of green branches and green leaves, which is the second peak of grape root growth, which can promote the grapes to produce a large number of fibrous roots, so as to strengthen the tree and be more conducive to wintering.

The fertilizer is mainly farmhouse fertilizer, and calcium fertilizer is applied at the same time, or a small amount of three elements are added.

For grape winter, strong trees or long trees, must be thinned first and then pruned, thinning requirements according to the original density and growth, can be carried out to leave one felling, or three felling. In order to prevent the branches from being airtight, poorly ventilated and transmitted, the fruit is poor, and the size of the fruit is serious.

If the grapes that are more than two or three years old have not been thinned, they must be cut at the best time this year to ensure that the tree shape is cultivated, and the degree of thinning is left one and one is left, but the tree is really weak, individual fields can be left for one and three, or not thinned and cut again next year, and the order must be thinned first and then pruned.

Pruning starts at the end of December and ends before the Spring Festival, do not prune too early, so as not to lose nutrients and affect the tree's potential. After pruning, it is necessary to apply callus antiseptic film in time to disinfect and seal. Do not use heavy shears instead of thinning.

For grapes, I believe many people will love it, after all, its taste is very sweet and sour, and it can always bring people good value when eaten. In different growth cycles, grapes do not have the same nutrient requirements, so we must pay attention to the supplementation of different nutrients, so that the grapes can grow better. What kind of fertilizer do grapes need?

The old farmer will teach you to remember to grasp these key points.

Peptide calcium. <>

Rational application. Grapes are of good quality after dissolving fertilizer in water.

In order to make the grapes have a unique taste, it is necessary to supplement a certain amount of magnesium, which can promote the improvement of the fruit and also enhance the production of enzymatic reactions. Of course, it is necessary to supplement in time after puffing and picking, and generally choose Fujinmen polypeptide magnesium, which can be well absorbed and can prevent the premature aging of fruits.

In the winter (November is the best time), the application of sufficient basal fertilizer will promote the smooth germination of the grapes in the following year. And when applying organic fertilizer, it is best to take deep fertilization, this fertilization method can not only improve the soil permeability of the vineyard, promote soil organic mineralization, so that the fertilizer is not easy to lose, improve soil fertility and water retention capacity, and is conducive to the plant to absorb ultraviolet rays to kill germs, promote root growth, so that grapes can get a good harvest in the coming year, and the yield per mu is more than 3000 catties.

What is the best fertilizer to apply.

The basal fertilizer applied to grapes in winter is mainly farmhouse fertilizer, supplemented by an appropriate amount of long-acting chemical fertilizer. The amount of use per mu is generally about tons, and 40 kg of phosphate fertilizer and 75 kg of nitrogen fertilizer can be added per mu in the farm fertilizer.

How to apply organic fertilizer.

The application of organic fertilizer should take the method of deep fertilization. Here's how:

Before ploughing and fertilizing, the weeds, grape residues and plastic film fragments on the ridges should be cleaned out of the garden, destroyed in a centralized manner, and should not be thrown into ditches and pools at will, so as to strictly prevent pollution of water sources and minimize the source of tobacco disease. In winter, the ploughing and fertilization position is generally sprinkled at a distance of 20 to 40 cm from the trunk, and then the soil is turned over, and the depth of the soil should not be too deep, with a depth of 20 cm. If the ploughing is too deep, a large amount of raw soil will be turned over to the surface, resulting in a mixture of raw and cooked soil, which often turns the grapes yellow and grows slowly.

The best time for winter pruning is from late December to the end of January. The main purpose of winter pruning is to thin out useless over-dense branches, pest and disease branches, disabled old branches and cut off the old branches of the current year, so as to reduce the water evaporation of the winter branches and select the mother branches that bear fruit in the following year.
