Grape planting technologyLao Qin shared what fertilizer do you need to put in summer black grapes when they bloom?

Grapes are usually grown in relatively flat and open areas, and summer black grapes are no exception. It is also necessary to ensure that the soil in the selected place has water permeability, air permeability and other properties, the application of fertilizer after sowing is essential, the demand for fertilizer in summer black itself is great, in order to ensure the yield must make good use of organic fertilizer.

The time of summer black grape planting is generally in spring and autumn, spring is sown around Qingming chrysanthemum, and autumn is sown after all the leaves have fallen off.

Summer black grape growing techniques.

1. Stuffy soil with celery

Grapes are usually grown in relatively flat and open areas, and summer black grapes are no exception. It is also necessary to ensure that the soil in the selected place has the properties of water permeability, air permeability, etc.

2. Tie vines and prune

When planting a cement pillar and a new shoot of 50-60 cm, it is necessary to wrap the vine around the pole, remove the tendrils in time, and carry out topping and capping.

3. Fertilizer

The application of fertilizer after sowing is indispensable, and the demand for fertilizer in summer is very large, and organic fertilizer must be used well in order to ensure the yield.

Methods for managing summer black grapes.

1. Pruning

There are 4-5 true leaves in the new shoots to grow out of the buds, and the branches and leaves in the dense part of the grape trellis are properly pruned to increase light transmittance and ventilation.

2. Watering

It is necessary to follow the watering principle of seeing dry and wet, and try to increase the number of watering times when the temperature is high in summer, and try to reduce the number of watering times when the temperature is relatively low in winter.

1. Shelf selection.

Fences are mostly used in the north, and single-stem V-shaped or scaffolds are mostly used in the south, and it is generally better to use fences for cultivation. When grape planting, for areas that need to be buried to protect from the cold, the row spacing can be 2 meters, the plant spacing is meters, 6,300 plants per hectare can be cultivated, and the yield can reach more than 30,000 kilograms per hectare in the second year under the general management level.

2. Trim ears and thin fruits.

If the summer black grape fruit spike is double, it is recommended to repair 1. If the spike is too long, pinch off the tip of the spike 1 5 1 4 10 days before flowering. On average, only 1 spike is left on each fruit branch, 1 spike is left on the medium growth new shoot, and no spike is left on the weak branch and cultivated branch.

Artificial fruit thinning can be watered with small water during the flowering and fruit setting period, or combined with spraying fungicides.

3. Swelling treatment.

Summer black grapes naturally grow with small fruits, so they need to be enlarged, which is conducive to increasing the yield of the grapes and increasing the value of the product.

4. Fruit bagging.

Grape bagging can prevent diseases, insect pests, bird pests, pollution, etc., so whether it is planted in the open field or greenhouse, it must be bagged.

5. Water and fertilizer management.

Organic fertilizers should be reapplied in the production of summer black grapes. When planting and building a garden, apply 1500 2000 kg of organic fertilizer per mu, apply 1 time of organic fertilizer in ditching, apply 1500 kg per mu, and chase 1 time of fast-acting nitrogen fertilizer in spring to promote germination and promote the growth of large fruit ears. One time of high-nitrogen three-element fertilizer was applied at the swelling stage, and one time of potassium fertilizer was applied before the fruit matured.

6. Scientific winter scissors.

Summer black grapes have good flower bud differentiation, high germination rate, and high fruiting branch rate, so pruning is generally based on short tip pruning, strong branches can be pruned in the middle tip, and generally tens of thousands of fruiting branches are left per hectare.

Fertilization techniques and precautions for grapes at various stages

1. Embryonic stage

Generally, germination fertilizer is applied once before germination to promote shoot growth and shoot germination. Nitrogen fertilizer was mainly applied during the germination stage, which could effectively promote the rapid growth of new shoots and leaves.

2. Flowering period

During the flowering period, the application of flush fertilization is mainly phosphate fertilizer (phosphorus is mainly used to promote flower bud differentiation), and the germination fertilizer should be applied before flowering, if you choose fast-acting fertilizer, it can be 3 to 5 days in advance, and compound fertilizer is applied 15 to 20 days in advance.

3. Young fruit stage

Flush fertilization should be applied at the stage of young grapes, and potassium fertilizer should be the main type to promote the rapid expansion of young fruits and prevent the occurrence of various potassium deficiency symptoms. Potassium can promote the ripening of young grapes, increase the sugar content of fruits, reduce the degree of acidity, and improve the taste and redness of grapes.

4. Swelling period

The potassium requirement in the swelling stage is more than that in the young fruit stage, which is the highest peak of the grape fertilizer requirement in a year, and the potassium fertilizer is sufficient, which can effectively improve the expansion rate of grape fruits, promote fruit coloring, sweetening, and prevent grain loss.

5. Coloring and maturity period

If the color is not good at this time, you can apply potassium fertilizer again, and if the root fertilizer is sufficient, you can properly apply some potassium fertilizer products to promote color and sugar.

6. Post-harvest

After harvesting, in order to recover quickly from injuries and survive the winter safely, without affecting the next year's product, some nitrogen fertilizer (to promote injury recovery) and phosphate fertilizer (to promote root development) can be rushed. It can be applied up to 1 month after harvest, the earlier the better.

7. Precautions

When planting grapes, usually after the bud starts, you can supplement the fertilizer or water-soluble fertilizer in time, to ensure the nutrients required for grape growth in time, promote seedlings, and promote the expansion of young fruits.

<> summer black grapes use No. 0, No. 1 and No. 2 grape bulking agents for summer black. Method 1: In the late flowering stage, use the No. 1 grape bulking agent special for summer black mixed with water, soak the flower spikes, and after 10 days, use the No. 0 grape bulking agent for summer black mixed with water to dip the fruit ears.

Method 2: 2-3 days after physiological fruit drop, use No. 0 grape bulking agent for summer black mixed with water, soak and dip the fruit ears, and after 8-10 days, use summer black special No. 2 grape bulking agent mixed with water to dip the fruit ears.

1. What kind of bulking agent is used for summer black grapes

Summer black grapes mainly use No. 0, No. 1 and No. 2 grape bulking agents for summer black. Here's how to use it:

1. Method 1.

1) When the summer black grapes are in full bloom, dilute with water with No. 1 grape bulking agent for summer black, and dip the flower spikes (each bottle of No. 1 grape bulking agent for summer black is diluted with 10kg of water).

2) After an interval of 10 days, dilute with No. 0 grape bulking agent for summer black with water, and dip the fruit ears (each bottle of No. 0 grape bulking agent for summer black is diluted with 12kg of water).

2. Method 2.

1) About 2-3 days after the physiological fruit drop of summer black grapes, dilute with water with No. 0 grape bulking agent for summer black, and dip the fruit ears (each bottle of No. 0 grape bulking agent for summer black is diluted with 15kg of water).

2) After an interval of 8-10 days, dilute with No. 2 grape bulking agent for summer black with water, and dip the fruit ears (each bottle of No. 2 grape bulking agent for summer black is diluted with 12kg of water).

3. Method 3.

After the physiological fruit drop of summer black grapes, when the fruit grows to the size of soybeans, dilute it with No. 2 grape bulking agent special for summer black with water, and dip the fruit ears (each bottle of No. 2 grape bulking agent for summer black is diluted with water 12kg).

Second, the trick of fertilization during the grape expansion period

1. The characteristics of fertilizer required during the grape expansion period.

1) In the early stage of the expansion of young fruits (the fruit is the size of mung bean) after the grapes are flowering, the top dressing fertilizer is mainly nitrogen fertilizer, and at the same time, combined with the application of phosphorus and potassium fertilizer, it can promote the growth of new shoots, expand the young fruits, reduce the size of the fruit, ensure that the fruit is large and uniform, and at the same time is conducive to the differentiation of flower buds. The amount of fertilizer applied during this period accounts for about 20-30% of the annual fertilizer application.

2) In the early stage of fruit coloring, the top dressing fertilizer is mainly phosphorus and potassium fertilizer, which can promote the secondary expansion of grapes, improve the sugar content and coloring degree of the fruit, and improve the pressure tolerance of the berry. The amount of fertilizer applied during this period accounts for about 10% of the annual fertilizer application.

2. Fertilization method.

1) After the grapes are flowered, when the young fruits are in the early stage of expansion, apply 15-20kg of urea and 15-20kg compound fertilizer per mu.

2) In the early stage of young fruit coloring, 20-40kg of high-potassium compound fertilizer or 5-10kg of phosphorus and potassium source reservoir and high-phosphorus and high-potassium water-soluble fertilizer should be applied per mu.
