Key Points of Greenhouse Grape Cultivation Technology
Today's sharing: Key points of greenhouse grape cultivation technology and experience in green plant maintenance to understand the planting methods of grapes. The following editor will provide you with detailed answers:
Because grape cultivation has certain requirements for light, temperature, humidity, etc., grape cultivation in the north usually chooses greenhouse for planting, which can facilitate the management of grape production and improve the yield of grapes. Although there are many benefits to growing grapes in a greenhouse, poor cultivation techniques can be futile. Let's take a look at the key points of greenhouse grape cultivation technology.
I. Choose the Right Grape Variety
If you want to grow grapes in a greenhouse, choosing the right variety is very important. First, choose a variety with good fruit quality, secondly, choose a variety with a medium maturity, and finally, choose a variety that is easy to transport and store. Common grape varieties include Kyoho grapes, and some hybrid varieties are also acceptable.
II. Planting Method
The greenhouse grape planting method should be determined based on your cultivation needs. If you choose early or mid-season grape varieties, it is more suitable for insulation greenhouse planting and then use the accelerated ripening method. If you choose a high-quality grape variety, it is suitable to use a late-season planting method, which can be grown in a plastic greenhouse to reduce the impact of humidity on grapes and reduce the invasion of diseases and pests.
III. Choose a Planting Site
Greenhouse grapes are suitable for a sunny, spacious, and dry location with good air quality. The soil should have good breathability, drainage, and fertility retention, with sandy soil being better.
IV. Film Coverage Work
Firstly, select the appropriate plastic film, focusing mainly on points such as thickness and light transmission, as these are very important for grape growth. If you are in an area with long daylight hours and high temperatures, the aging rate of greenhouse plastic film will be faster, and if affected by strong winds, the film may be damaged. The use of greenhouse plastic film is best not to exceed two years, as it easily affects light transmission and insulation. Therefore, to achieve the best application value of the film, it must be replaced every year. After covering the top film, it is necessary to cover it with a pressure line.
Control the insulation and moisturizing effects of the film coverage. The temperature inside the greenhouse should not be too high in the early stages of film coverage. About one month after covering the film, the seeds begin to germinate, and the temperature inside the greenhouse should not be too high.
V. Post-Management Work
In the later stages of grape cultivation, a reflective film should be laid on the original film-covered infrastructure, which can control the light intensity inside the greenhouse to about 30%, which is very effective for photosynthesis in plants. Provide certain nutrients according to the growth of grapes, as different growth periods require different fertilizers. For example, it is best to ensure the use of phosphorus and potassium fertilizers during the fruit expansion period to promote plant growth.
In winter, attention should be paid to pruning the grapes, focusing on the vines with the larger lengths as the main pruning targets.
The above sharing of the key points of greenhouse grape cultivation technology and understanding the planting methods of grapes is all the content that green plant enthusiasts might refer to.
