Grape Cultivation Techniques and Management
If you want to learn about grape cultivation techniques and management, as well as related introductions to the timing and methods of grape planting, the editor will introduce them as follows.
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, staking and pruning.
1. Planting Time
Generally, the planting time for grapevines is between March and April, and some are also planted between September and October.
2. Soil Selection
Grapevines do not have high requirements for soil, but in order for them to grow and develop normally, it is best to choose sandy loam or light loam with loose soil texture, good permeability, drainage, and fertility, slightly acidic to slightly alkaline soil with low bulk density,
3. Water and Fertilizer Management
During the process of planting grapevines, watering is required weekly to keep the soil moist. There's no need to water after heavy rain, but waterlogging should be avoided. Grape fertilization mainly occurs in autumn, preferably after harvest, it can also be done after the vines are unearthed and staked in spring. The base fertilizer mainly consists of organic matter, with about 5000 kg of organic matter needed per mu, which is spread in 10-15 cm deep soil pits and mixed evenly with soil. It is necessary to apply top dressing in autumn, generally using 50-100 grams of urea and 150-200 grams of ammonium sulfate to promote germination and fruiting of grapes. In addition to soil fertilization, foliar fertilization is also required, usually using 0.3% urea, 0.3%-0.5% phosphorus acid二氢盐, 0.1% sodium chloride, and 3% phosphorus acid calcium. It is also important to pay attention to weeds in the field and clear them in a timely manner to ensure the normal growth of grapevines,
4. Staking and Fixation
To facilitate field management, staking can be chosen for grapevines, generally using single-rail frameworks for fixation, which is beneficial for ventilation and light transmission, improving grape quality. The row spacing is generally 2-3 meters, the frame height is 1.2-2 meters, with a post every 6 meters in each row, and a horizontal wire every 50 cm on the post,
5. Pruning
In spring, pruning is necessary. Initially, only two strong buds are retained. When the later buds grow to 10-15 leaves, pruning is required again, usually leaving 1-2 leaves at the top. It is also necessary to remove tendrils to avoid nutrient consumption.
