Detailed Explanation of Key Points of Greenhouse Grape Cultivation Techniques
Grapes are a very common fruit in all regions, and the peak season for grapes is generally in winter and spring. In the past, due to seasonal and technical reasons, grapes could only be eaten in season, but now grape cultivation techniques have gradually matured, and now grapes can also be eaten out of season. This is mainly achieved through greenhouse cultivation, so today I have brought you the cultivation techniques for greenhouse grapes, let's take a look below!
1. Variety Selection
For greenhouse grape cultivation, we first need to select suitable cultivation varieties. Varieties suitable for greenhouse cultivation should be selected with short growth cycles and high sugar content. For example, Kyoho, Muscat Hamburg, etc. When selecting varieties, we should comprehensively consider the local cultivation environment, market demand and prospects. The cultivation varieties must first of all have strong adaptability. For example, if cultivating in the north, because the temperature is relatively low and the temperature difference is also relatively large, the cultivation varieties must have good adaptability to temperature changes.
2. Greenhouse Location
The yield of greenhouse grape cultivation is directly affected by the choice of greenhouse location. If planting on slopes, the greenhouse should be built on higher ground. This can ensure good drainage for the greenhouse and adequate sunlight. Sunlight is the key to ensuring high yield of greenhouse grapes and can increase the sugar content of grapes. Then pay attention to choosing good soil. The planting soil must have sufficient fertility and strong permeability. High-quality soil is also the key to ensuring normal grape growth.
3. Flower and Fruit Management
When cultivating grapes in greenhouses, if there is no artificial release of bees, there are no natural bees to pollinate them. Therefore, during the flowering and fruiting period of grapes, we must do a good job of artificial pollination. Without pollination, the number of flowers and fruits of grapes will be reduced, affecting cultivation benefits. After pollination, properly thin out the fruit clusters grown on the grape plants. Remove some poor-quality and extremely poor grape fruit clusters, and reasonably retain fruit. Keep one fruit cluster per branch, and then when the berry diameter grows to about one centimeter, promptly remove diseased berries, deformed berries and other undesirable fruits.
4. Environmental Control
As just mentioned, sunlight is still very important for grape growth. If the local natural sunlight duration is not long enough, then we must promptly do a good job of artificial supplemental lighting to meet the light requirements of grape growth. Then there is temperature regulation. Grapes have different temperature requirements at different growth stages. Therefore, we should reasonably adjust the temperature according to weather changes and the growth period of grapes. The temperature should not be too high. When the temperature is too high, cooling can be carried out through ventilation and spraying water.
The above is a brief introduction to greenhouse grape cultivation techniques. The fertilizer and water management of greenhouse grapes is similar to ordinary cultivation, so you can carry out watering and fertilizing according to the fertilizer and water management measures of ordinary cultivation methods. That's all for today's introduction. This article is for reference only, and I hope it can help everyone!
