Grape Cultivation Methods and Precautions
A guide to share knowledge on grape cultivation methods and precautions in the field of horticulture, details are as follows:
Grape Cultivation Methods and Precautions
Grapes can be propagated through grafting and cutting. For cutting propagation, select a robust branch, let it dry in a shaded area, and then plant it in moist soil. Grafting involves attaching a superior variety to a resistant rootstock to create a new plant. One month before harvest, strictly control irrigation and spray a solution of potassium dihydrogen phosphate or potassium sulfate on the leaves to improve quality.
When to Plant Grapes
It is better to plant grapes about 15 days before they sprout in spring, approximately in March to April. There is also planting about half a month after the leaves fall in autumn, roughly in September to October. For spring planting, in the Huang-Huai region, it can be done in mid-to-late March, and in the Jingjin region, it can be done from late March to early April.
Methods of Planting Grapes
Grapes can be propagated through grafting and cutting. For cutting propagation, select a robust branch, let it dry in a shaded area, and then plant it in moist soil. Grafting involves attaching a superior variety to a resistant rootstock to create a new plant, known as a grafted seedling.
Steps for Planting Grapes
1. Planting Time: Grapes do not tolerate low-temperature environments, so it's best to plant in spring, from January to May, after the soil thaws and before sprouting. The later the planting time, the weaker the growth.
2. Land Preparation and Ridge Formation: When planting grapes, control the row spacing at 1.8-2 meters, form ridges along the rows, apply sufficient base fertilizer, and then deeply turn the soil by about 40 centimeters to mix the soil and fertilizer thoroughly.
3. Seeding and Maintenance: After planting grapes, it is necessary to maintain the moisture of the soil but avoid waterlogging. During the growth period, apply thin fertilizers frequently, avoiding thick or raw fertilizers.
Precautions for Grape Maintenance
During the growth of grapes, water them promptly, but strictly control irrigation one month before harvest to improve fruit quality. When the fruit is coloring, spray a solution of dichlorvos or carbendazim every 10 days to prevent diseases and pests. One month before harvest, spray a solution of potassium dihydrogen phosphate or potassium sulfate on the leaves to increase sugar content and quality of the fruit.
The above is a comprehensive explanation of grape cultivation methods and precautions, hoping it can help you.
