Detailed Explanation of Key Techniques for Greenhouse Grape Cultivation

Grapes are a common fruit, rich in vitamins and suitable for people of all ages. So how are grapes grown? Below, we introduce greenhouse grape cultivation techniques.

1. Insulation measures inside the shed and grape variety selection

The main structure of the greenhouse is: walls, beams and columns, insulation film, etc. Generally, the greenhouse is 50-80 m long from east to west, about 8 m wide from north to south, with a rear wall height of 3 m. The wall thickness should be more than 1 m, and slag and sawdust should be used as a buffer layer, with a heat storage and insulation layer applied inside to provide insulation. When selecting varieties, choose medium-maturing varieties with vigorous tree growth, strong fruiting capacity, disease resistance, large berries and high quality, such as Kyoho and Jingya.

2. Planting management

The most commonly used method for grape planting is trellis planting, specifically divided into single plant single row and double plant double row. During planting, attention should be paid to the amount of fertilizer and water, temperature regulation, and pest and disease control.

3. Flower and fruit management

The purpose of greenhouse grape cultivation techniques is to grow grapes with large berries, good color and excellent taste. Therefore, the number of clusters and berries per vine must be controlled. Flower cluster thinning can be carried out from when the fruiting branch reaches 20 cm in length until flowering. Generally, only one cluster is kept per fruiting branch. This can effectively reduce the number of berries and allow the remaining berries to grow larger.

In summary, through greenhouse grape cultivation, farmers can effectively increase their economic income and better meet the consumption needs of consumers.
