What are the grape cultivation techniques
For many girls, let's continue reading about the grape cultivation techniques and related green plant content throughout the grape planting process!
Grapes are juicy, sweet, and rich in nutrients. Today, we will learn about the planting methods of grapevines from planting time, soil selection, water and fertilizer management, trellis fixing, and pruning.
1. Planting Time
Usually, the planting time for grapevines is from March to April, and some are also planted from September to October.
2. Soil Selection
Grapevines do not have high requirements for soil, but to ensure normal growth and development, it is best to choose loose, well-drained, and fertile sandy loam or light loam with slightly acidic to slightly alkaline soil.
3. Water and Fertilizer Management
In the process of planting grapevines, it is necessary to water the grapevines weekly to keep the soil moist. There is no need to water if it rains heavily, but avoid waterlogging. Grapes are mainly fertilized in autumn, preferably after harvesting. It can also be done in spring after the vines are unearthed and trellised. The base fertilizer mainly consists of organic fertilizer, with about 5,000 kilograms of organic fertilizer needed per mu. A 10-15 cm layer of topsoil can be dug in the orchard, and the fertilizer can be spread in the dug pits, mixed evenly with the soil, and then the topsoil is filled back. In autumn, it is also necessary to apply top dressing, usually using 50-100 grams of urea and 150-200 grams of ammonium sulfate. This can promote the germination and fruiting of grapes. In addition to soil fertilization, foliar top dressing is also required for grapes, usually using 0.3% urea, 0.3%-0.5% monopotassium phosphate, 0.1% sodium chloride, and 3% calcium superphosphate. It is also necessary to pay attention to the weed situation in the field, clearing weeds in a timely manner to ensure the normal growth of grapevines.
4. Trellis Fixing
To facilitate field management, grapevines can be supported with a trellis. The single fence framework is commonly used because it is conducive to ventilation and light penetration, improving the quality of grapes. Generally, the row spacing is 2-3 meters, the height of the trellis is 1.2-2 meters, and there is a post every 6 meters in each row, with a horizontal wire stretched every 50 centimeters on the posts.
5. Pruning
It is necessary to prune appropriately in the spring. Initially, only two strong buds need to be left. When the later shoots grow to 10-15 leaves, they need to be pruned again, usually leaving 1-2 leaves at the top. It is also necessary to remove tendrils to avoid nutrient consumption.
The above is a specific introduction to the grape cultivation techniques and the entire process of planting grapes, hoping to bring some knowledge of flowers and green plants to plant enthusiasts.
