How to Plant Greenhouse Grapes
A brief knowledge of experience, introducing you to how to plant greenhouse grapes and the small experience of plant cultivation techniques for grape planting. Next, the editor will answer your questions in detail.
With the improvement of people's living standards and the emphasis on healthy eating, people are increasingly pursuing green and organic agricultural products. Faced with market demand, grapes are commonly cultivated in greenhouse greenhouses, which not only increases the yield of grapes but also can increase farmers' income. This article will analyze the key points of greenhouse grape technology to increase the quality and yield of grapes.
One, Greenhouse Site Selection
In the process of cultivation, using the greenhouse to cultivate grapes, environmental conditions play a key role in the growth and quality of grapes. To achieve high-quality and high-yield grapes, it is first necessary to select a good geographical location that is not too high in elevation and relatively flat, saving costs during the transportation of grapes. Secondly, ensure there is sufficient water supply for irrigation and good drainage performance to prevent rainwater from entering the greenhouse after rain, which is not conducive to grape growth. Moreover, soil selection is also crucial. Choose relatively loose soil and thick soil layers, ensuring good permeability and water retention, which results in sweeter grapes and helps to improve the quality and economic benefits of grapes.
Two, Variety Selection
Different grape varieties have different yields in different environments, so it is essential to select varieties based on local climate, soil, and other environmental conditions. This approach utilizes and cultivates local grape resources, combined with flat terrain and sufficient sunlight conditions, to promote high-quality and high-yield grapes.
Three, High Yield Grape Cultivation Techniques
1. Soil, Fertilization, and Water Management
(1) Soil and Fertilizer. During the grape planting process, it is necessary to frequently till the soil deeply and replace fertile soil in the field to accumulate nutrients, improve soil structure, and enhance fruit quality, thus promoting better growth of grapes. Fertilizers are essential nutrients required by grapes during growth and are one of the material foundations for grape production. Adequate fertilization is needed at each stage of grape growth to produce high-quality grapes and promote healthy growth. In addition to commercially available fertilizers, animal manure is also a good option. It is not advisable to use excessive chemical fertilizers, as this can reduce the nutritional value of grapes and harm human health. Therefore, during fertilization, it is necessary to consider the growth condition of grapes and soil fertility, study the soil structure for growth, and scientifically promote grape growth.

(2) Watering. Grapes require a large amount of water during growth. From germination to flowering, the demand for water gradually increases, and it is essential to ensure that grapes receive adequate water during this stage. After entering the maturity stage, the water requirement of grapes begins to decrease and is relatively slow. To better promote grape growth, it is necessary to water according to the changes in grapes at different stages, without waiting until the grapes are short of water to water them or overwatering, as this can severely affect the survival of grapes. It is also important to pay attention to excessive water during heavy rain and timely drainage to prevent the drowning of grape roots.
2. Pruning
Timely pruning of grape vines during growth, removing bad vines, and leaving vigorous ones help grapes absorb more nutrients and water, achieving a balance and improving grape quality. During pruning, try not to leave too many branches to avoid nutrient deficiencies. After grapes are put into production, pruning is even more critical. It is necessary to trim the vines reasonably, removing excessively strong or weak ones to promote overall growth. When pruning, leave longer branches on strong vines and shorter ones on weaker ones, and leave some short branches on side branches. In hot summer weather, if grape vines are not adequately watered, they will lack water, causing leaves to curl and branches to wither. Therefore, it is essential to prune withered leaves to promote normal branch growth.
3. Environmental Control
The temperature and humidity in the greenhouse are crucial for grape growth. During greenhouse cultivation, it is necessary to control the environment of the greenhouse, especially temperature and humidity, to ensure the growth of grapes. According to grape growth, keep the greenhouse warm during the period from covering to germination. If the temperature difference at night is too high or the temperature is too low, measures can be taken to warm the greenhouse appropriately, but ensure the temperature is not too high. After germination to flowering, the temperature changes and day and night temperatures should be controlled. In the later stages, reduce the day-night temperature difference. For grapes in bloom, the maximum temperature should not exceed 34°C and can be controlled between 26-28°C. It is important to ventilate and cool when the greenhouse temperature is too high to keep the air circulating. During the flowering period to the panicle growth period, the humidity in the greenhouse can be controlled at around 80% to improve grape quality.
