Can the grape cold shed survive the winter safely, and is the cold shed suitable for growing grape s

Look at where the north of Shandong can't be.

The cold shed can be used for grape cultivation and seedling.

How the grapes are cared for.

Preparation of seedlings: Seedlings are purchased from autumn to before the Spring Festival, and the purity and quality of seedlings are higher. After the seedlings are purchased, leave 2-3 full buds and cut them flat.

The seedlings are buried in bundles in front of the ditch, the depth of the ditch is meters, the length and width are not limited, and the direction is not limited. The top layer is about 30 cm above the ground, and the cover soil is slightly above the ground level, so it is not irrigated but splashed with water. This method is prone to heat and is planted immediately after the soil thaws in spring.

Seedlings are set to dry: Chengju stupid clear seedlings leave 3 buds to dry.

Transplanting and fertilization: After the grapes have sprouted, they can be transplanted, and after transplanting, they can be transplanted with Root Le Rooting Agent to promote the growth of the vines.

OK. It is recommended to choose a flat terrain, fertile soil, leeward to the sun, convenient irrigation and drainage of the plot to build a garden, try to use the north-south direction, face south to north, the height of the shed 3 can hang 5 films), the width of 18 24m is appropriate, too narrow is not conducive to the early Minghe finch heat preservation, too wide is not conducive to ventilation and cooling. This makes it possible to grow three rows of grapes in the cold shed.

The planting density varies according to the variety, site conditions, shaping methods, seedling resources and other kinds of seedlings. Generally, the plant spacing of small trellis is 4m.

OK. The cold shed refers to the plastic greenhouse, which does not need to be covered with straw tape, and only one layer of plastic film is blind. Growing grapes in cold sheds is a low-investment, easy-to-manage project that allows grapes to be marketed 1 to 2 months earlier.

Grape cold shed planting should pay attention to the prevention and control of diseases caused by high temperature, high humidity and poor ventilation, the main diseases in the cold shed are gray mold, downy mildew, anthracnose and other diseases, thrips, blind bugs, mites and other insect pests, on the basis of comprehensive control measures, to play a good light rod stone sulfur mixture, in the future according to the law of disease and the occurrence of the situation for prevention and control, disease control, eliminate pests.

Here's how to survive the winter:

1. Master the cold resistance of grapevines: Grapevines are mainly affected by frost in winter, mainly by their roots, followed by stems and branches. When the ground temperature at the root system of grapes drops to 16, the root system will be frost damaged to varying degrees; When it reaches 18, they will all freeze to death.

Therefore, the temperature of the grape roots in winter should be kept above 16.

2. Pay attention to timely filling of frozen water: 10 days before the grapes are buried in the cold-proof soil in winter, cold-proof water should be filled once, in order to prevent root frost damage and early spring drought. When irrigating, it must be fully irrigated, and the soil must reach a saturated state as the standard. When the ground soil is slightly dry, bury the soil to prevent cold.

3. Pay attention to the timely removal and burial of the first cold-proof soil: due to the late autumn and early winter, not only the temperature is low, but also the wind is strong, and the water content of the grape stems and branches is easy to evaporate due to the wind. When the grapes fall leaves, cut them in time, and then tie the branches and vines with straw ropes, etc., and bury the cold-proof soil when the temperature is stable at about 2 for five consecutive days.

Don't bury too much for the first time, and take not showing branches as the standard.

Fourth, pay attention to bury the second cold-proof soil in a timely manner: bury the second cold-proof soil, and it is ideal to carry out it when the temperature drops to 0, that is, bury the second cold-proof soil before freezing. In winter, the ground temperature drops to 12 at 80 cm below the surface, and the thickness of the cold-proof soil is 20 cm to 30 cm, and then the ground temperature decreases by 1, and the thickness of the buried soil increases by 10 cm.

In order to achieve a better cold-proof effect, when burying the second cold-proof soil, it should be covered with corn straw or grass before burying the soil. This significantly increases the temperature at the roots of the grapes. The width (bottom width) of the cold-proof soil should not be less than a meter, the front is trapezoidal, the upper width is 1, 2 meters, and it can be patted with a shovel after burial.

In addition, the thickness of the buried cold-proof soil is also related to the local soil quality. Generally speaking, sandy loam soils, especially those with a fine sand layer or a mixed layer of sand and gravel at the bottom of 1 metre, are thicker, because the temperature in such areas not only drops quickly but also in winter. On the contrary, in the black soil area, the bottom layer is mostly yellow clay, which not only cools down slowly but also has a relatively high ground temperature, so the soil can be buried shallowly.

5. Pay attention to the land point and the ditch for returning the seal: when digging cold-proof soil, be sure to take soil between the rows 2 meters away from both sides of the main trunk of the vine, not too close to the roots, so as not to make the cold air flow from the soil ditch to the roots of the vines, causing frost damage. In places with irrigation conditions, the soil ditch should be irrigated with water to freeze into ice after freezing, which can not only prevent the invasion of cold air, reduce the thickness of the frozen soil, but also help the root system to overwinter and drought prevention in the following spring.

Where there are no irrigation conditions, the soil ditch can also be covered with grass and other materials.

Resources.

In cold areas, the soil is buried in winter to prevent the cold, and the arrows are repaired before the soil is buried. In areas where the soil is not buried, arrows are repaired two weeks after the leaves have fallen.

The grapes are relatively cold-resistant, the roots in the north are covered with soil of 20---30 cm, and the water is filled to prevent dryness and freezing, and the south is managed normally.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: What does the cold shed grapes help the fallen leaves:

There are many people who grow grapes in the cold shed to help them lose their leaves, but there are very few people who actually make money from growing grapes. Because in the process of growing grapes, the places that need to be paid attention to are very complex. Only if everything is done particularly well, from cultivation to management, can the grapes grow better.

And the faster the grapes grow, the better, the sooner they can be marketed. Grape growers must know that if the grapes are marketed late, it means that they will not make much money. And those growers who often make money by growing grapes have their grapes on the market very early.

Grape growers often encounter problems such as very few flower spikes of grapes, and the flower spikes are particularly weak. The most serious is the phenomenon of flower spike degradation. To understand why grapes are in this condition, we must first understand the reasons for this situation.

Many melons and fruits have a natural dormancy period, and grapes naturally have a natural dormancy period of about two months. As we mentioned above, the earlier the grapes are on the market, the more money you make.

As we mentioned above, the earlier the grapes are on the market, the more money you make.

Suggestion: Dear [Xian Hall File Flower] Now that the epidemic is repeated, you must pay attention to the <> of the slag when you go out and pretend to be chaotic

Wear a mask when you go out, wash your hands frequently! I wish you a happy life <> when to help the grapes fall in the cold shed.

Leaves begin to fall around mid-October.

Summary. Dear, the grapes are relatively delicate, it is recommended that you take anti-freezing measures, and the following points are hoped that you will give them.

Dear, the grapes are relatively delicate, it is recommended that you take anti-freezing measures, and the following points are hoped that you will give them.

1. Ground buried cold-proof method (1) The pruned branches are taken off the shelves in one direction, straightened, bundled and placed flat on the furrow surface**. In order to prevent the branches from being crushed when buried, it is best to put rodenticide poison at the base of each plant in the base of the tree or straw, and in areas with serious rodent infestation, rodenticide should be put at the base of the branches to prevent biting and damaging the branches. (2) When buried, squeeze both sides of the branches and vines tightly, and then cover them to the required width and thickness.

3) Take the *ditch close to the side of the plant and not less than 50cm away from the outer edge of the cold-proof pile (about 1 5m from the base of the plant) to prevent the root system from being frozen from the side. (4) When buried, it is necessary to shoot the real wheel chant while cultivating * to prevent ventilation in the pile. When the soil begins to freeze, it is best to fill the ditch with freezing water once or twice to increase the temperature and prevent the root system from being frosted.

Second, the underground ditching and burying method at the edge of the row from the rhizome 50cm in the direction of the line: the width and depth of 40 50cm each wide open the cold-proof ditch, the bundled branches into the ditch; You can cover the straw first, or you can bury it directly*. This method of trenching for many years has a damage and destructive effect on the root system, and it is labor-intensive and time-consuming, and is currently applied in individual areas.

3. Deep head like ditch planting cold protection method This method is suitable for dry climate areas and well-drained plots. Before planting, dig a trench 30 to 40 cm deep, and there are two ways to plant and grow grapes in the trench to protect against the cold. (1) Buried cold-proof:

Tie the branches and vines and put them in the ditch, for the convenience of the shelves and reduce the damage of the branches and buds, you can put a layer of straw on the branches and bend the vines, and then bury them*. This method is more economical than the actual burial on the ground, labor-saving, and has a higher safety factor. (2) Hollow cold protection:

First, the branches and vines are tied and placed in the ditch, and then small wooden poles are placed horizontally on the ditch, and the straw is spread on top of it* to the required width and thickness. This method has a better moisturizing effect than the buried method, and the safety factor of wintering is larger, but it is more material-intensive.

Fourth, plastic film cold protection method In recent years, some vineyards in Donghong and North have tried to wear and wear plastic film to prevent cold, and the effect is good. The practice is to first cover the branches with wheat straw or straw 40cm thick, cover them with plastic film, and use * around them. However, special care should be taken not to break the film, so as not to cause frost damage due to cold air penetrating people.

Fifth, the simplification of the slip cold protection method of the use of cold-resistant rootstock grafted grapes, because the root system cold resistance is 2 4 times stronger than the self-rooted seedlings, so it can greatly simplify the cold-proof measures, saving 1 3-1 2 cold-proof labor. For example, in the northern part of Chengde, the organic mulch can be removed and buried directly*, so as to ensure the safe wintering of branches and roots. Therefore, the use of cold-resistant rootstocks and the implementation of simplified cold-proof are the directions for the development of grape production in severe winter areas.
