How to achieve high yield in greenhouse grapes
If you want to understand the explanation of how to achieve high yield in greenhouse grapes in the field of green plants and flowers, the following will introduce you to this knowledge.
How to achieve high yield in greenhouse grapes
Fresh grapes are sour, sweet, and juicy, and there are many grape varieties in China. The main cultivation methods of grapes are open-field cultivation and greenhouse cultivation. So what are the key points of greenhouse cultivation?
Greenhouse Construction
Common greenhouse types for grapes include single-span greenhouses and arch-shaped greenhouses, and to ensure sufficient sunlight, the greenhouses are generally oriented north-south when built. When planting in the greenhouse, the method of separate planting can be used, and the trellis in the greenhouse should be set up according to actual conditions.
Planting
Firstly, it is necessary to choose suitable grape varieties that are adaptable, disease-resistant, have a short growth cycle, and high yield. Secondly, during the planting process, it is important to adjust the fertilization ratio according to local conditions, promoting root growth during the appropriate growth stage to ensure smooth planting.
Grape Seedling Management
Grape seedlings are relatively vulnerable, so it is necessary to carry out scientific and reasonable seedling management. Firstly, during the fertilization process, ensure sufficient fertilizer while avoiding excessive fertilization that can damage the seedlings. Therefore, when fertilizing, it should be done in small amounts, and after each fertilization, appropriate watering or spraying should be done. Secondly, it is necessary to carry out pest and disease control work in advance to prevent problems before they occur. Based on the growth status of the seedlings at different growth stages, the best drugs should be chosen scientifically and reasonably.
It is worth noting that herbicides should not be used. Additionally, it is important to adjust the growth form of the grapes, making reasonable use of the greenhouse space to provide a sufficient and suitable environment for grape growth. Grapes need to go through a climbing stage, so the greenhouse should have corresponding trellises built, and the height of the trellises should be reasonable to ensure that the grape vines can climb on them.
Grape Cultivation
Firstly, suitable cultivation conditions should be provided for grape growth, and existing resources should be used reasonably according to the natural conditions of the grape planting area. Although grapes are plants, they enter a dormant period like animals in winter, so it is necessary to keep the greenhouse warm during winter. Secondly, it is important to cover the greenhouse with plastic film and remove it at the right time based on natural factors. Timely covering not only maintains warmth and humidity but also effectively improves the yield and quality of grapes.
Framework Shape Characteristics
To ensure grape yield and avoid overcrowding, attention should be paid to the distribution of the greenhouse surface and adjust the planting distance. Regular drying should be done step by step to maximize the growth space for grapes.
Branch Management
To ensure the growth form of grapes, it is necessary to manage the grape vines promptly. Specifically, in the first year of pruning, only the new shoots of the grapes need to be pruned; in the second year of pruning, an appropriate number of branches should be maintained to guide their normal growth.
In summary, the cultivation management of greenhouse grapes involves several key points, and fruit farmers can refer to more information for reference, hoping it is helpful to everyone.
