How much does it cost to grow grapes in greenhouses?

The winter in Northeast China is severe cold, the temperature is -30-40, and the annual active accumulated temperature is (10. 2567-2779, it is difficult to ensure the survival of grapes without greenhouse insulation.

In view of the severe cold climate in Northeast China, it is best to choose more cold-tolerant grape varieties, such as mountain grapes, in addition, you can choose to plant Cabernet Sauvignon from Changli, rose fragrance from Tianjin Binhai District, Chardonnay, Guirenxiang, Cabernet Sauvignon, Cabernet Franc, snake dragon Sauvignon, Merlot, Carignans, Ugni Blanc and other varieties.

All I know is that grapes are very temperature-sensitive.

And what to do if you don't have enough sunlight in winter.

It's hard to get.

The cost of planting one acre of grape land on land is about 10,000 yuan.

Grapes need 44-60 cement columns per acre [row spacing.

One acre of land needs 150-300-480 seedlings [row spacing.

It is calculated based on 450 hours of employment during the basic employment period. In the first year of open field cultivation, the minimum investment of one mu is more than 10,000 yuan! Rain-sheltered cultivation fees are not included.

Grape seedlings are very cheap, a cuttings seedling is only 6-8 cents, and a year's first-class old seedlings are only yuan.

As for the management and technical issues, it mainly depends on the local technical costs, and there may be differences in different regions. But it's pretty much the same.

Adaptation to local conditions is the most important, and costs vary from region to region, relative but not particularly significant.

At present, there are two main planting modes, one is open field cultivation and the other is greenhouse cultivation. Among them, the use of greenhouses to grow grapes has problems such as high cost and high management technical requirements. So, why do you still use greenhouses for cultivation?

The benefits of growing grapes in greenhouses.

Grapes are grown in greenhouses and used in the north, mainly to solve the problem of temperature. Greenhouses can raise the ambient temperature of the grapes and promote early ripening. In general, grapes grown in the open field can be marketed up to a month earlier.

There is a saying, called"Grasp the market and light up in advance"Grapes that are marketed in advance have the best advantages and are conducive to improving economic benefits.

Then, the use of greenhouses to grow grapes in the south also became popular. It stands to reason that the climatic conditions in the south are more suitable for grape growth, and there is no problem with temperature. Therefore, the reason why greenhouses are used to grow grapes has only one purpose, which is to avoid diseases caused by high temperature and humidity climate.

The southern climate is high, rainfall, high temperature and high humidity area, easy to induce various fungal diseases, not suitable for planting more popular, high-efficiency Eurasian grapes, such as Chardonnay.

Cabernet Sauvignon, Cabernet Franc, seedless white sweetheart grapes. Therefore, the purpose of planting grapes in greenhouses in the south is to breed excellent varieties, improve grape quality and improve planting efficiency.

Although growing grapes in greenhouses can bring many benefits, there are still some things that need to be paid attention to in the planting process, as follows:

Precautions for planting grapes in greenhousesGrowing grapes in greenhouses can be listed in advance and get a higher selling price. As a result, many growers want to increase their yields to make more profits. This is understandable, but it is not possible to blindly increase the yield in order to pursue profits, the load is not controlled, and the pruning is too heavy, which brings problems such as insufficient nutrients, poor color, and reduced sweetness from the fruit ripening period to the sugar accumulation period, but the gains outweigh the losses.

In addition, the greenhouse cultivation of grapes has high requirements for humidity, on sunny days, the relative humidity of the air is required to be about 50%, and even at night it is even more than 90%. If the humidity and moisture in the greenhouse are not accurately grasped, it is easy to induce diseases. For example, if the moisture in the soil is too high, the evaporation will be very large, and the transpiration of the crops will be accelerated, so the air humidity.

It is too large, which creates conditions for the infiltration of germs. Therefore, in the process of planting in the greenhouse, we must grasp the humidity in the shed.

Grapes like drought, especially in the ripening season, a rain, a year's hard work is in vain, greenhouse planting is mainly table grapes, because of the anti-season early market, high efficiency is good, and grapes in the inland ripening season rain more, fast ripening, rain will cause grape yield reduction and harvest, so now with greenhouse planting, can play a role in stable yield, high yield now promote many new varieties of grapes, are also in need of greenhouse cultivation, but also for people's curiosity, and rare new varieties, the market is small, use greenhouses to go to market early and late, while getting **.

For the harvest out of season. Because you can adjust the temperature and sunlight in the greenhouse, you can ignore the influence of the season on the plants.

Because grape growth has high temperature requirements, in order to improve the survival rate of grapes, they will choose to use greenhouse planting.
