How to Increase Grape Yield
Here are some tips on how to increase the yield of grapes, introduced by our editor for netizens.
How to Increase Grape Yield
Grapes are woody vines of the grape genus. Young branches are cylindrical, with longitudinal ridges, hairless or sparsely pubescent, and leaves are elliptical. Its fruit is one of the most popular fruits among people, usually round or oval. Grapes are native to Western Asia and are cultivated worldwide. With the growing market demand for grapes, grape cultivation has become a good choice for many farmers. So, what planting techniques can improve the yield and quality of grapes?
Grape Planting Conditions
According to professional growers, grape cultivation is more suitable for mid-latitude inland areas in China in terms of geographical and climatic conditions. These areas have a temperate continental climate, with less rainfall, sufficient sunlight, and a large diurnal temperature range. This climate is conducive to the accumulation of sugars and reduces the consumption of nutrients. When planting grapes, the terrain should be flat, which is beneficial for the normal growth of grapes, as well as for their picking and transportation.
Grape Cultivation Techniques
2.1 Planting and Cultivation
Grape cultivation uses a trellis system. The trellis protects grapes from intense sunlight, ensures the quality of grape cultivation, and has a good germicidal effect. Therefore, fruit farmers generally use trellises for outdoor grape cultivation. Before planting grapes, growers adjust the rafters to determine the shape of the trellis. This way, during the grape planting process, it can effectively improve planting efficiency and increase grape yield and quality. The quality of trellis installation also affects the formation and yield of grapes.
2.2 Pruning Techniques
During grape growth, grape branches and leaves should be pruned at any time. The main tasks of pruning include binding vines, pinching hearts, leaving buds, and removing tendrils. Pruning can effectively ensure the healthy growth of grapes. It can control the growth of grapes, promote the development of grape production speed, and ensure both the quality of grapes and early harvest. As grapes grow, it is recommended that farmers regularly prune them. Generally, two days after grape planting, grape vines can be pruned, and new shoots should maintain a certain distance from the ground. After pruning, each grapevine can only leave one fruit cluster and 4-5 inflorescences to effectively ensure the quality and nutrition of the next year's grape fruits. Even in winter, grapevines should be pruned without fruits. Some branches should be retained, and the rest should be pruned.
2.3 Fertilization and Water Management
Shallow trench fertilization should generally be carried out in spring. Before planting, water and fertilizer management should be done. When grapes grow vigorously, we need to water and fertilize to speed up the growth of grapes. During the application of water and fertilizer, attention should be paid to methods such as applying less, frequent applications, and shallow applications to ensure that the soil has enough water and that grapes can effectively absorb fertilizers to ensure their growth. Fruit farmers should do weeding and tillage work. Different fertilizers should be applied at different growth stages of grapes. During fertilization, irrigation can be combined with fertilization. The amount of irrigation water can be adjusted and controlled according to weather changes to ensure that grapes can absorb enough nutrients.
Post-Harvest Management of Field-Grown Grapes
3.1 Heavy Application of Base Fertilizer Technique
In autumn, higher temperatures can effectively help decompose base fertilizers. After the base fertilizer is decomposed, it can ensure that grapes and grape fruits absorb enough nutrients, prevent withered branches, and restore some withered branches and leaves. After grape harvesting, growers should continue to apply base fertilizers to grapevines to ensure the growth of next year's grapes. It is recommended to use shallow trench fertilization, digging circular trenches about 20-30 cm around the grapevines. Fruit farmers can top-dress grapes according to their growth cycle and adopt corresponding fertilization methods based on the growth condition of grapes.
3.2 Drought Resistance and Leaf Protection Techniques
Dry weather will have an adverse effect on the growth of grapes. Drought can cause grape branches and leaves to wither and fall, preventing grapes and grape fruits from getting enough nutrients and affecting the healthy growth of trees and fruits. Therefore, during high-temperature months of July and August, fruit farmers should pay close attention to the weather and drought conditions in the planting area, focusing on the growth of grape branches and leaves. If the drought persists, with severe withering and falling of grape branches and leaves, it is necessary to water the grapevines in time to supplement moisture, and pay attention to the amount of water during irrigation. The main irrigation methods include furrow irrigation and hole irrigation.
3.3 Disease and Pest Control Techniques
To ensure the yield and quality of grape crops, disease and pest control should be emphasized. During grape growth, disease and pest control should also be adjusted according to time changes. Taking May as an example, the middle of May is the peak period for powdery mildew and white rot, while the late May becomes the peak period for grape downy mildew. Therefore, in terms of disease control techniques, fruit farmers should use different pesticides for spraying to ensure the control effect. It can also be controlled in other ways, such as bagging fruits 40 days after fruit setting. During bagging, add an appropriate amount of wettable powder to ensure the fungicidal effect and improve fruit quality.
In summary, farmers need to pay more attention to details and management in the process of planting grapes to effectively increase the yield and quality of grapes. I hope this article can be helpful to you.
