How to promote the germination of grapes, the method of grape germination

Greenhouse grape germination technology 1, the correct choice of heating time.

Under natural conditions, grape dormancy generally begins in August, with the deepest dormancy from late September to late October, and tends to be completely released from dormancy in mid to late January of the following year, so it is advisable to start warming the greenhouse grapes around mid-January.

2. Slow heating during germination period.

The period from the beginning of warming to bud break is the time when the grapes are warmed up to the time of bud break, which is generally 25-30 days. The first 7-10 days, cover the grass during the day, uncover it at night, keep the temperature about 20 during the day, keep 5-10 at night, and gradually increase the temperature after that, so that the temperature is kept at 28-30 during the day and 13-15 at night, and the greenhouse humidity is kept above 90 during the germination period.

3. Use artificial methods to break the dormancy of grapes.

3 1 Lime nitrogen breaks dormancy.

Lime nitrogen is a chemical, highly toxic, with the chemical name of calcium cyanamide, and it is used with great care. Specific usage: add lime nitrogen to water 5-10 times, stir fully to make it uniform and consistent, and then let it stand for 5-8 hours, and take the supernatant for later use.

In the protected area, gently apply the bud eyes with a brush or brush. This treatment can make the grape bud bud 10-15 days earlier, but the bud eyes treated with lime nitrogen are prone to shoot growth after germination, which affects the development of flower buds, resulting in low fruit setting rate, small fruit spikes, and affected yield.

3 2 gibberellin ten urea treatment breaks dormancy.

This method can significantly improve the germination of grape bud eyes, which is non-toxic and relatively safe. The specific method of use is: 50-100 mg of gibberellin ten 200 times urea, stir well, and then evenly spray on the grape branches or use a brush, brush, etc. to apply on the bud eye part, the effect is good.

This treatment is also prone to the growth of grape branches, which should be overcome in the later management.

The two methods are pure fart, and I have undergone rigorous experiments, and the results of the experimental vines are later than normal germination, and some branches even die! Miserable.

15d and 20d before normal germination, spray directly with 30 times and 40 times with Domeizi and an appropriate amount of Domex partner.

AbstractThere are four methods of grape germination promotion: warm water germination, variable temperature germination, sand storage germination, and drug germination. Among them, warm water germination is to use two parts of hot water and one part of cold water to put the seeds in it for continuous stirring, and stop when the water temperature is lower than room temperature, and 20% of the seeds will germinate after 2-3 days. Variable temperature germination is to put the seeds in hot water and stir them continuously for 5 minutes, and then soak them in cold water for 2-3 days to germinate.

How grapes are budidized.

Hello, I have seen your question and am sorting out the answer, please wait a while

Grapes need to be bud breaking, right?

There are four methods of grape germination promotion: warm water germination, variable temperature germination, sand storage germination, and drug germination. Among them, warm water germination is to use two parts of hot water and one part of cold water to put the seeds in it for continuous stirring, and stop when the water temperature is lower than room temperature, and 20% of the seeds will germinate after 2-3 days. Variable temperature germination is to put the seeds in hot water and stir them continuously for 5 minutes, and then soak them in cold water for 2-3 days to germinate.

Refrigeration germination is carried out in March and April every year, using about 3 to 4 times the size of the seeds for burial, and it needs to be placed in the temperature and humidity suitable for seed germination, and germination can be carried out after 60 days.

Drug germination: Grape germination is to stimulate the gibberellin and abscisic acid in the seed, and gibberellin can be used to promote germination, so that the metabolism in the seed can be accelerated to promote the growth of the seed, so as to achieve the conditions of seed germination.

I mean mine is an old vine, this year the stubble is flat, the greenhouse, the tree has been cut for almost a month, and there are no new shoots, can you use germination medicine at this time.

The branches of the old vine boasted that there was no moisture.

Is it mulched?

How about the usual fertilizer and water management.

There is a mulch film that is now removed.

Are there pests and diseases?

Fertilizer and water management are good.

If not, then strengthen some nutrition, spray nutrients, and water the sprout water.

It's a greenhouse again, and the temperature should be enough.

Just add nutrients.

Yes, it's just slow.

The useless greenhouses in our village have sprouted.

What's more?

Whether the sprout water should be sprayed with a jug or watered.

It is mainly topdressing nitrogen fertilizer, appropriate amount doped with boron fertilizer, iron fertilizer, zinc fertilizer and fast-acting fertilizer.

1. Warm water germination. When it comes to understanding grape seed germination methods, it is best to choose the use of warm water germination treatment. Use two parts hot water to one part cold water and place the seeds in it and stir constantly. When the water temperature drops below room temperature, 20% of the seeds will germinate in 2 to 3 days.

2. Variable temperature germination. The germination of the seeds is to stir the seeds in hot water continuously for 5 minutes, and then soak them in cold water for 2 to 3 days to promote germination. The temperature of the water should be between 10 and 60, and too hot water will scald the seeds.

3. Sand storage germination. Sand germination is carried out in March and April every year, and it is necessary to bury it with about 3 to 4 times the size of the seeds, and it needs to be placed in a temperature and humidity suitable for seed germination, and germination can occur after 60 days.

4. Drug germination. Grape germination is to excite gibberellin and abscisic acid in the seeds, and gibberellin can be used to promote germination, so that the metabolism in the seeds can be accelerated and the growth of seeds can be accelerated, so as to achieve the conditions for seed germination.

1. Choose a few ripe grapes.

2. Remove the flesh and take out the seeds inside.

3. Soak in warm water at about 30 degrees for a day and night before germination.

4. Mix the seeds with sifted clean river sand in a ratio of 1:3:4.

5. Cover the glass lid, place it on the kang, and pour some warm water in time.

6. After a few days, pour out for inspection and mix up and down, inside and outside, and then put it into a flower pot and cover it to keep warm and moisturize.

7. Check the germination situation every day, the germplasm is good, the temperature and humidity are appropriate, and the seeds can germinate in about eight to ten days.

1. Seed germination.

To promote the germination of grape seeds, it is necessary to clean them first, clean the residual pulp and juice on the surface of the seeds, and then soak or spray them in a disinfectant solution, and then soak them in warm water of about 30 degrees Celsius, and soak them in hail for about 24 hours, and the grape seeds can be sown by absorbing enough water.

2. Soil preparation. Defeated sails.

The soil used to grow grape seeds is not suitable for ordinary soils, and it is necessary to prepare soil with a loose and porous structure, good ventilation and drainage capacity and a certain basic fertility, preferably sandy soil, because such soil is not prone to compaction and can be used for a long time.

3. Watering and moisturizing.

After planting the seeds into the prepared sandy soil, it is particularly important to water the orange lead and moisturize the soil, the first watering should be fully watered to ensure that the soil where the grape seeds are located is completely moist, but can not leave stagnant water, keep it in a slightly humid state for a long time, and water regularly to ensure humidity.

4. Stable temperature.

In addition, if you want to ensure that the grape seeds can germinate as soon as possible, you also need to stabilize the temperature of the soil and environment where the plant is located, stabilize it at about 15 degrees Celsius, and maintain it at about 12 degrees Celsius at the beginning, and then gradually increase the temperature, so that in a warm environment, grape seeds can generally emerge in 10 days.

In order to promote the germination of grape seeds, it is necessary to clean and disinfect them, and then soak them in warm water for 24 hours to allow them to absorb enough water, in addition, you also need to prepare loose and fertile sandy soil, after planting it in the soil, properly watering and moisturizing, the temperature is stable at about 15 degrees Celsius, and germination can occur in about 10 days.

1. Seed germination.

For the germination of grape seeds, Yuqing first cleans them, cleans the residual pulp and juice on the surface of the seeds, and then soaks or sprays them with a disinfectant solution, and then soaks them in warm water of about 30 degrees Celsius, and soaks them for about 24 hours, and the grape seeds can be sown by absorbing enough water.

2. Soil preparation.

The soil used to grow grape seeds is not the general soil can be competent, it is necessary to prepare the soil with a loose and porous structure, good ventilation and drainage ability and a certain basic fertility.

3. Watering and moisturizing.
