What kind of fertilizer should be applied to grapes in winter?

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.

Fertilize the grapes in winter. Organic fertilizer and nitrogen, phosphorus and potassium complete fertilizer are the main fertilizers, supplemented with phosphorus and potassium fertilizers. 400 500 kg of rotted human and livestock manure, 40 50 kg of nitrogen, phosphorus and potassium (15 15 15) potassium sulfate or nitrate sulfur or pure sulfur-based compound fertilizer, 80 100 kg of superphosphate or calcium-magnesium phosphate fertilizer, 25 30 kg of potassium sulfate per mu, and a shallow annular ditch with a depth and width of 25 30 cm was dug at a distance of 40 50 cm from the grape plant.

What is the best fertilizer to use for winter application of base fertilizer for vineyards?

The period of applying the fertilizer is as early as possible, after the grape is harvested, the fertilization work is carried out immediately, and the method of deep application can be used, that is, the ditch is 50-60 cm away from the grapes, the ditch is 40 cm wide and 40-60 cm deep. It can also be carried out by mechanical application.

2. The type of fertilization: organic fertilizer and bacterial fertilizer are the main ones, and sulfur-based nitrogen, phosphorus and potassium compound fertilizers are used in conjunction with Pai. At the same time, it is necessary to add an appropriate amount of medium and trace elements.

3. The amount of fertilization: the amount of fertilizer should be determined according to the age of the tree, the tree potential, the year's fruiting and other factors, and the amount of fertilizer should account for about 70% of the total fertilizer consumption throughout the year in principle.

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.

<>1. It is better to use solid inorganic fertilizer for grapes. According to the needs of grape growth and development, urea was applied 3 times in the first year of planting (2 times less than soil cultivation), 50 grams of plants each time; Top dressing ternary compound fertilizer 2 times, 100 grams each time, 9 kg of urea per mu and 12 kg of ternary compound fertilizer are applied throughout the year, which are 1 5 and 1 4 of top dressing per mu of soil cultivation, of which the supplement of trace elements adopts the method of foliar spraying, combined with spraying 2 3 times a year.

2. Due to the vigorous growth of substrate cultivation grapes, the huge root system, and the ability to resist pests and diseases is greatly improved, the first year of planting is 3 4 times with medication, and the result is less than 5 times in the annual growing season of that year.

3. The frame type used in grape soilless cultivation is that the trellis is better than the hedge. Because the trellis is small, the grapes grow vigorously, and the fruit is not as good as the trellis. According to the test results, the use of flat scaffolding is not only easy to increase yield in the early stage, but also easy to improve the quality.

4. Grapes need a lot of nutrients, and nitrogen fertilizer is the main factor in the early stage, and phosphorus and potassium fertilizer increase accordingly after entering the fruiting period. In addition to organic fertilizer, 80-150kg of nitrogen, phosphorus and potassium are required per hectare per crop (harvest), which should be adjusted according to different varieties, yields, tree potentials and soil fertility. The basal fertilizer is applied after winter, and 10,000kg of chicken and duck manure, 3750kg of cake fertilizer and 3750kg of superphosphate are applied per hectare.

5. Top dressing is applied before the shade buds, before flowering and fruit expansion period, and timely spraying of strong fruit tiling, nitrogen fertilizer is mainly used in the early stage to promote the growth of branches and flower spikes, and phosphorus and potassium fertilizer are added during the fruit expansion period to improve quality. Extra-root topdressing spray with urinary cord and potassium dihydrogen phosphate can promote fruit enlargement and uplift and ripening.

Fertilizer. 1. When pouring planting water, it is recommended to add seaweed essence or fulvic acid to promote the rapid growth of the root system;

2. For the first time in spring, choose high-phosphorus and medium-nitrogen fertilizers, such as 10-30-20, give priority to ensuring the growth of underground roots, and drip irrigation of 1 to 2 kg per mu. Note: Start to use fertilizer after seeing the tendrils, and do not use fertilizer to stress the root system in advance;

3. Then choose high-nitrogen fertilizers, such as 30-10-10, to ensure the rapid growth of branches and leaves, drip irrigation 2 to 3 kg at an interval of 20 days, and use 4 to 5 times;

4. Before and after the beginning of autumn, switch to medium phosphorus and high potassium fertilizer to ensure the lignification of new branches and promote the differentiation of flower buds, and use twice at an interval of 20 days;

5. The application of basal fertilizer in autumn must be carried out at the earliest when the average temperature during the day is lower than 30, and the latest should be completed one month before the fall of leaves. The basal fertilizer applied in autumn is mainly farmhouse fertilizer, supplemented by compound fertilizer. The quality of flower buds is good, the orchard with a full frame of tree shape is carried out in accordance with the standard of high-yield tree fertilizer, and it is recommended to apply more than 2 tons of farmhouse fertilizer per mu, about 30 kg of compound fertilizer, and about 50 kg of calcium, magnesium and phosphorus fertilizer.

Orchards with poor flower bud quality can reduce the amount of compound fertilizer.

What is the best fertilizer for grapes? Not only nitrogen, phosphorus and potassium, but also everything that a grape needs.

Grape planting technologyLao Qin shared that summer black grapes need dust when they bloom, what fertilizer to put here? Paixun.

Grapes are planted with rotten manure or compound fertilizer and amino acid compound fertilizer.

The fertilization method is mainly solid inorganic fertilizer. According to the needs of grape growth and development, urea was applied 3 times in the first year of planting (2 times less than soil cultivation), 50 grams of plants each time; Top dressing ternary compound fertilizer 2 times, 100 grams each time, 9 kg of urea per mu and 12 kg of ternary compound fertilizer are applied throughout the year, which are 1 5 and 1 4 of top dressing per mu of soil cultivation, of which the supplement of trace elements adopts the method of foliar spraying, combined with spraying 2 3 times a year.

Seedlings are fertilized slowly, i.e. fertilized first after planting red grapes, and watered enough after planting Cronson grapes. When the grape seedlings have new shoots, the planting has been successful and can be properly fertilized and watered. Strip sowing fertilization should be carried out at a distance of 20cm from the roots of seedlings, the fertilization depth is about 12cm, and the fertilization is about 20kg per mu.

It can be used with 45% light chemical fertilizers, controlled-release fertilizers or fruits. Fertilize and water later. Fertilization during the growing season.

After the first application of slow seedling fertilizer, about three weeks later, the second top dressing is started. This fertilizer can be applied together with diammonium phosphate.

You can use 30g of ternary compound fertilizer and 20g of diammonium phosphate special fertilizer for fruit trees, with a distance of 20-25cm between red roots, open a 10cm deep hole, and apply. After filling, water once, and keep the soil layer of Bihui always moist. Fertilize after the water breaks, apply a second fertilizer at an interval of about three weeks, and then apply another fertiliser.

At this time, the temperature is already high, the soil temperature is also rising, and the original mulch film can be removed. Then dig a 10 cm deep trench for the red liter plant every 25 cm, bury 50 grams of 45% nitrogen, phosphorus and potassium compound fertilizer, and 50 grams of special fertilizer for red liter fruit trees. After filling, irrigation is carried out in a fused way to improve fertilizer utilization.

Fertilization in the second half of the fruit, regret the omission of this fertilizer, to increase the amount of potassium fertilizer, is conducive to improving the quality of fresh fruits, strawberry sugar content, fruit color is good.

Generally, 25 30 grams of ammonium sulfate are used per plant, 50 grams of ammonium sulfate ternary compound fertilizer are used for each plant, and 50 grams of special fertilizer for red fruit trees. Trenching and burial are still used to improve fertility and reduce evaporation. Don't forget to water after fertilizing.

At the same time, the independent leaves should be sprayed with 10% plant ash solution, which can improve the quality of bright red fruits and make the grapes evenly remove the bag during the discoloration period. At the beginning of planting, it is necessary to apply basal fertilizer in autumn. Organic fertilizer should be used for base fertilizer, which is conducive to microbial fertilizer, various trace element fertilizers, etc.

The applied basal fertilizer should be well composted and placed in a furrow 50 cm from the plant. The ditch is 30 centimeters wide and 40 centimeters deep. Fill the ditch symmetrically with chemical fertilizer, and then water it after it has been filled.

Generally, the application is completed around the National Day, and it is not suitable to be too late.

5000 kg of organic fertilizer, 100 kg of soybean cake, and 100 kg of beneficial microbial fertilizer should be applied at one time. Although it can also be applied before the budding stage of the red carpet, the sooner the organic fertilizer is applied, the better the actual effect. Although the weather is cold in autumn, the soil temperature is still very high, and the rhizomes are still in a lively situation.

The grapes are dormant during the winter and cannot be fertilised.
