The importance of spring pruning Spring pruning is the key to the maintenance of potted grape trees. Its importance is mainly reflected in the following aspects: 1. Promote plant growth: Spring pruning can remove sick and weak branches and excessively dense branches, allowing the plant to ventilate and transmit light, and is conducive to the growth of new buds.
2. Increase yield: Reasonable pruning can adjust the nutrient distribution of plants, so that more nutrients can be used for fruit growth and increase grape yield.
3. Improve quality: Spring pruning can remove sick and weak branches, reduce the occurrence of pests and diseases, and improve the quality of grapes. The best time for spring pruning The best time for spring pruning is generally carried out before the grape germinates. Generally, from mid-March to early April, the grape trees have not yet germinated, and pruning has little impact on the plant. Steps of spring pruning 1. Clean up the plants: Clean up weeds, dead leaves and other debris around the potted grape trees to create a good environment for pruning.
2. Remove sick and weak branches: Observe the plant, cut off sick and weak branches, overdense branches, crossed branches, etc., and keep the plant ventilated and transparent.
3. Trim the main vines: When pruning the main vines, keep 2-3 strong main vines, cut off the rest, and keep 20-30 cm in length.
4. Trim side vines: The pruning of side vines should be carried out according to the growth status and space of the plant. Generally, 1-2 strong side vines should be retained, and the rest of the side vines should be cut off. The pruning length should be retained at 10-15 cm.
5. Trim the fruiting branches: The pruning of the fruiting branches should be adjusted according to the growth of the fruit. Generally, 2-3 strong fruiting branches are retained, and the rest of the fruiting branches are cut off. The pruning length should be retained to 5-10 cm. Maintenance after spring pruning 1. Fertilization: After pruning, the plants can be supplemented with nutrients, and nitrogen, phosphorus and potassium compound fertilizers can be applied.
2. Watering: Keep the soil moist but avoid standing water.
3. Prevention of pests and diseases: After pruning, spray pesticides in time to prevent the occurrence of pests and diseases.
