Can soaking grape seedlings sprout, and can soaking grape branches with water to sprout?

OK. Top dressing is selectively fertilized according to the different phenological stages of the grapes. It can be divided into germination fertilizer, flowering fertilizer, fruit strengthening fertilizer and ripening fertilizer. The exact amount of fertilization should be based on the yield requirements of the tree and the fertility of the local soil.

Germination fertilizer: about 2 months, apply a germination fertilizer, germination fertilizer is mainly nitrogen fertilizer, you can use imported water-soluble fertilizer nitrogen fertilizer, using furrow application or hole application.

Pre-flower: In late April, apply a pre-flower. Pre-flowering fertilizer, mainly nitrogen fertilizer and phosphorus fertilizer, with Yanwo water-soluble fertilizer high nitrogen and high phosphorus type, need to be watered immediately after fertilization.

Strong fruit fertilizer: Yanwo high potassium water-soluble fertilizer can be used, and furrow application or hole application is still used.

The growth period of young fruits is the peak fertilizer demand of grapes in a year, and fertilization at this time not only promotes the growth of young fruits, but also has a good effect on the growth of branches and leaves of the year.

Coloring fertilizer: also known as ripening fertilizer.

Post-harvest fertilizer: After the fruit is harvested, due to the large nutrient consumption of the tree, fertilization is required to ease the tree and delay defoliation.

In recent years, with the improvement of grape fertilizer and water management technology, irrigation fertilization has been gradually adopted to replace traditional fertilization methods in production.

Top dressing begins in mid to late April, and fertilization is carried out using drip irrigation. 2kg of water-soluble compound fertilizer with nitrogen, phosphorus and potassium content of 15:15:15 can be applied per mu, which can be used at the same time as water-soluble fertilizer and water fertilizer, once a week, during which the soil is kept moist.

At the same time, during the grape growing season, according to the grape's nutrient requirements, topdressing can be carried out outside the roots. If the grapes are sprayed with foliar fertilizer after fruit set, they can continue to supplement nutrients, and Yanwo potassium dihydrogen phosphate can be used to supplement the phosphorus and potassium needs of the tree. 7-10 days after fruit harvest, it helps the plant to regulate growth, promote nutrient absorption, and restore the tree's vigor as soon as possible.

Grape roots cannot be sprouted and planted.

Grape propagation methods

There are many methods of grape propagation technology, which can be roughly divided into sexual reproduction and asexual reproduction, sexual reproduction is the use of plant seeds for planting, and asexual reproduction is through cuttings, grafting, striping and other methods through plant vegetative organs for reproduction. In the actual production process, in addition to seed propagation, the most used is cuttings propagation, which is very convenient and fast.

Grape cuttings propagation technology

1. Cuttings collection

The collection of cuttings is generally in autumn after the leaves fall to before the freeze, combined with winter pruning, to select fully mature, robust and full annual branches, full bud body, no diseases and pests, diameter to. Pay attention to cut off immature branches, and spray stone sulfur mixture for disinfection after collection.

2. Nursery selection

Choose sandy soil with convenient transportation, close to water sources, flat terrain, leeward and sunny, easy drainage, deep soil layer, and soil pH value to.

3. Germination

Because it is difficult to root directly from cuttings and the survival rate is low, it is necessary to soak with rooting powder solution first, the base of the cuttings is downward, the soaking time is 2 hours, and the soaking depth is 3cm. Or you can also use one-thousandth of the rooting powder solution to dip it quickly, pay attention to the top of the cuttings can not touch the medicine, otherwise it will inhibit growth.

4. Cuttings

After the previous preparations are done, you can wait for cuttings, generally at the surface temperature of 15, around the end of April, the east and west ridges. Insert 2 rows per ridge, plant spacing 10 to 15cm, top bud facing up, and fill with enough water at one time after insertion.

5. Management after cuttings

After cuttings, water enough at one time, generally about 20 days can produce full buds, each plant leaves a strong shoot, in order to ensure that the nutrients are concentrated and promote growth.

In general, cuttings are one of the main methods of grape propagation, which has the advantages of simplicity, high survival coefficient and low cost, and the ability to maintain some of the original characteristics of the grape variety. Of course, cuttings are not without drawbacks, so in actual production and application, it is necessary to combine the characteristics of grape varieties, planting environment and other factors to choose the appropriate propagation method.

Summary. Do not wipe out all the new shoots after grape pruning, remove a part, leave a few strong buds, and do not be too close to each other, do not be reluctant, otherwise it will affect the growth and branch fullness.

The new shoots sent out after grape pruning should not be completely extinguished, and a part of it should be removed, leaving a few strong buds of the brigade, not too close to each other, and not to be reluctant, otherwise it will affect the growth and branch enrichment.

Last year, the vines that my friend gave me were all teething from the roots.

The old rod is no longer teething.

Can it be raised? When the roots are in the ground, the grape seedlings show the symptoms of slow growth, short internodes, dark green leaves, small and thick leaves, and inhibition of leaf propagation, resulting in twisted and wrinkled leaves.

This year, it grows to a height of meters thicker than chopsticks, how to prune and manage?

How many are the same?

Is it necessary to preserve such vines?

1. Light: When planting vines, choose a location that is not covered by houses and trees. 2. Erection frame:

When the vines are young, they start to erect the shelves and tie the branches to the shelf. 3. Top dressing: The grapevines should be sprayed once before flowering to promote Kao Spine Surge No. 1.

4. Pruning: Pruning is carried out when the vine grows its first true leaves, and the excess new shoots are erased during the budding period.

It is not easy to get rooted.

You can try it by adding rooting agent to the water.

No. There must be roots and stems.

Grape Cultivation Method:

The pot should not be too small, and when it is time for the seedlings, you can use a smaller pot first, but as the vines gradually grow, the soil is too little, the nutrients are too little, and the nutrients can no longer keep up. Choose at least a pot with a diameter of 30 cm or more. To increase breathability, add a little coarse sand to the soil.

It is better not to have an airtight basin. I tried to plant a grape in a porcelain pot, and for two years in a row, the grapes didn't grow much at all, and I checked the potting soil, and found that after watering, it was difficult to dry, and after the rain, the pot was muddy for a long time. So it is not conducive to the development of grape roots.

Don't plant two grapes, or one grape with other fruit trees and plants. I planted two grape trees together, and there were some small greens and stuff in the open space next to them. Then almost none of the grapes in this pot bear fruit, and sure enough, you can't be greedy.

And the weeds inside have to be cleaned up for everything.

Don't water too much. If it is placed on the balcony, you must pay attention to this problem, and the open air is slightly better. Because the balcony itself is not well ventilated, if the soil is too wet, the evaporation is small. The grapes themselves can't drink as much water, which only adds to its burden.

When setting up a shelf, you don't need to use iron or a shelf that transfers heat quickly, especially in the high temperature of the middle of the summer, which will be red and easy to burn the grape branches, so that the originally long green vines will wither and the leaves will turn yellow.

Increase fertilization during the grape growing season. I saw an eldest sister fill the foam box for planting grapes with organic fertilizer in the spring, and make her own kitchen waste or something. The grapes grew very vigorously and had a lot of fruit.

However, during the flowering period, apply less fertilizer, otherwise if you water more, it will be very tolerant of flowers and fruits.

Soil is critical and should be loosened regularly. But be careful not to hurt the roots. If you see that the soil in the pot is as hard as a stone, then the vines should be dug up and replanted.

Or replace it with loose, breathable and nutritious humus. Add enough well-rotted fertilizer as base fertilizer. The grapes will grow very well next spring.

If you feel that the grape growth is not good, you can consider changing the pot or changing the soil. Prune the branches in winter. However, pruning should be used in the kind of large number of grape bases, generally planted at home will not grow so lush and so large, if it is on the terrace or the roof of the building, you can prune a little.

No, there must be a section that has been soaked in liquid medicine.
