Post-harvest Management of Greenhouse Grapes
The editor introduces you to the post-harvest management of greenhouse grapes in the aspect of green plants and flowers, some very good tips and knowledge, recommended for collection!
Post-harvest Management of Greenhouse Grapes
Grapes are adaptable, have a high market demand, and bring good economic returns. Developing greenhouse grapes can effectively enhance the value of these grapes. In recent years, greenhouse technology has become increasingly advanced, usually allowing greenhouse cultivation to start 10-15 days earlier than traditional methods, filling the gap in the off-season grape market. However, with the stable support of technology, many fruit farmers do not pay enough attention to post-harvest management, resulting in a significant decrease in grape yields by 10%-20% the following year. Today, let's talk about the post-harvest management of greenhouse grapes.
Post-fruit Fertilization
After harvesting greenhouse grapes, it is necessary to replenish nutrients in a timely manner to restore tree vitality. Post-fruit fertilization plays an important regulatory role. It is recommended to fertilize according to the plant's growth condition, applying about 12 kg of effective nitrogen fertilizer per mu, and spraying a 0.3% urea solution 2-3 times to promote normal tree growth.
Cultivation and Weeding
In August and September, greenhouse grape gardens are prone to various weeds. After harvesting, it is important to cultivate the land and remove weeds promptly, as well as to conduct deep tillage. At the same time, affected by the high temperatures in August and September, fruit farmers should also pay attention to drought resistance and irrigation. In case of drought for 15-20 days, furrow irrigation should be adopted in a timely manner.
In addition, it is necessary to keep the orchard clean, promptly cutting off diseased branches, leaves, fruits, and dead branches to reduce the sources of pests and diseases.
Disease and Pest Control
After fruit harvest, fruit trees are prone to fungi such as downy mildew, black spot, and rust, especially from August to September, which is the peak period for downy mildew, especially in rainy years. Therefore, it is important to continue paying attention to disease control after harvesting. Additionally, it is necessary to prevent pests such as beetles, grape moths, and leafhoppers.
Careful Pruning
Pruning and shaping grapes after harvest is very important. To reduce nutrient consumption, the first step in pruning is to remove tendrils and weak branches, as well as severely diseased leaves. The second step is to ensure the integration of fruiting branches, nutritional branches, and regenerative branches.
In summary, this article briefly introduces some key points of post-harvest management of greenhouse grapes. When harvest season comes, fruit farmers must pay more attention to these management issues, as this is to ensure the grape yield for the following year.
The detailed explanation of the post-harvest management of greenhouse grapes shared above is hoped to bring you some help in green plant management!
