Grapes are fruits that many people like to eat, and they are grown in many areas. It’s already autumn, and it’s not long before the grapes are going through the winter. The grape will stop growing when the temperature drops to 10 degrees Celsius, and the cold resistance of the grapes after entering the dormant period will have some limitations. In order to make the grapes safe for winter, We must do a good job of wintering and cold-proof management measures for grapes, and we will work together to understand them.
1. Ground buried cold method
The ground-buried cold-proof method is to remove the trimmed branches in one direction, comb the bundles, and lay them flat on the soil. In the cold area, it is necessary to prevent the branches from being crushed. In addition, some straw, straw and other coverings can be placed on the upper part of the plant and on the upper and the sides of the branches, and then the soil can be compacted. When the grapes are covered with soil, it is necessary to prevent the leakage of cold air. The thickness of the mound is about 40 cm and the width is about 1.8 m. After the soil is frozen, the winter water can be poured into the soil on both sides to prevent side freezing.
2, underground trenching method
The method of underground trenching is to open a deep trench with a width of 50 cm and a depth of about 50 cm from the root of the plant, and then put the bundled branches into the ditch to ensure the cold-proof effect. Put in straw, straw, etc., and then cover the soil. This method has a good anti-cold effect, but it should not be used for years to avoid damage to the root system.
3, deep ditch planting cold method
Deep-growing planting cold-proof method requires deep digging of planting ditch when planting, generally around 40 cm, and the grape plant can grow directly in the ditch. In winter, it can be buried or not buried. According to the actual situation, the cold-proof effect is better.
4, plastic film cold method
When the plastic film is cold-proof, it is necessary to pay attention to not pierce the film, but also to pile up the soil, so it can be operated when the labor is sufficient. First cover the branches with straw or straw, then cover the plastic film, and finally cover it with soil. In this way, straw, film, and mound can all play a role in preventing cold and keeping warm, and it is very easy for grapes to survive winter.
The above is the management method and technology of the grape overwintering. The grape is well managed for wintering and has a good influence on the high yield and high quality of the grapes in the coming year. Therefore, in order to effectively ensure the grape yield, we must do a good job of wintering management of the grapes.
