How to manage grapes just germinated
Today, let's introduce the knowledge of how to manage grapes just germinated. Regarding the management of grapes just germinated and how to care for them, let's learn about it together.
1. Water management. After a long period of dormancy, grapes enter the period of vegetative growth, requiring a large amount of water to restore vitality. Therefore, before the grapes germinate, it is necessary to supplement them with water, known as the germination water. Germination water is also one of the stages with the highest water demand during the entire growth cycle of grapes.
2. Nutrition and fertilization. Before the grapes germinate, it is necessary to apply fertilizers according to different varieties and their growth characteristics, also known as germination fertilizer. About 15 days before the germination period, medium-fertilizing varieties should be supplemented with compound fertilizer containing nitrogen, phosphorus, and potassium at 10-15 kg/acre; for varieties with weaker growth and higher fertilizer requirements, use 15-20 kg/acre of compound fertilizer containing nitrogen, phosphorus, and potassium, supplemented with 7.5-10 kg/acre of urea.
3. Pruning. During the grape germination period, pay attention to leaving only one bud at each node, removing double buds, diseased buds, weak buds, and buds in improper growth positions.
4. Pest and disease control. Before the grapes germinate, also known as the downy stage, use sulfur preparations (such as a 3-degree Baume solution of lime sulfur) for garden cleanup, making sure to leave no死角, which can effectively reduce the incidence of diseases and pests for the year, especially for powdery mildew and mites. When the grapes have 2-3 leaves, use a protective fungicide + insecticide/acaricide throughout the garden, especially in areas with more rainfall, to prevent the occurrence of high-humidity diseases.
5. Application of dormancy-breaking agents. To promote the germination of grapes, we usually take a series of measures such as scoring the buds, using dormancy-breaking agents like cyanamide or lime nitrogen to help grapes break dormancy and promote uniform germination.
