What are the methods of grape fertilization
Grapes are a kind of vines in the grape genus. Its fruit is one of the most popular fruits. It can be eaten fresh or made into raisins or wine. It is rich in glucose, minerals, vitamins, and other nutrients. Regular consumption of grapes can prevent the occurrence of cardiovascular diseases and has high medicinal value. What fertilization methods are needed to increase grape yield? Let's take a look next!
Basic Fertilization
Basic fertilization provides most of the nutrients needed for plant growth every year, usually in larger amounts, accounting for about 2/3 of the total amount of fertilizer. It mainly consists of organic fertilizers and slow-release fertilizers, which can improve the soil. According to data, basic fertilization can be applied in autumn, but in real life, basic fertilization can be applied before more leaves fall. Autumn application of basic fertilization is beneficial for the decomposition of organic fertilizers and early utilization by plants, as well as for injured roots. Basic fertilization is mainly applied in trenches. The trench depth is 40-60 cm, and the width is 30-40 cm. According to the amount of soil and fertilizer, the applied fertilizer is thoroughly mixed with the soil and then applied in the trench that needs to be refilled. If it is winter fertilization, the soil can be covered according to the trenching situation to prevent freezing due to cold weather. Also, avoid getting a cold when digging the trench, and provide irrigation water after fertilization.
Top-dressing
If only basic fertilization is applied in greenhouses, it sometimes cannot meet the nutritional needs of growth and fruiting. Therefore, if the roots do not meet the nutritional requirements, top-dressing should be carried out in a timely manner. Fast-acting fertilizers are generally used for top-dressing. In the early stage of grape top-dressing, nitrogen fertilizers are mainly used (should be shallowly applied), and phosphorus and potassium fertilizers are mainly used in the middle and later stages (phosphorus fertilizers are more mobile and should be deeply applied).
Soil Preparation Fertilization
Soil top-dressing is mainly carried out in the plant roots. The fertilization depth, depending on the different fertilization parts, should not be too deep before the buds, otherwise the shallow roots will be damaged by the excess.
Nitrogen fertilizers (urea, etc.) and potassium fertilizers are applied in shallow trenches between two grape plants on the tree board. After covering the soil, the water source can be irrigated. Or before the rain to the ground, so phosphorus fertilizers must be applied as deeply as possible in the trenches.
(1) Fertilization before Bud Break
In the soil before germination, available nitrogen is the main fertilizer. Compound fertilizers can be applied appropriately depending on the situation. Fertilizing at this time is beneficial for promoting bud growth. This top-dressing is especially important. For vigorous tree growth, you can choose not to fertilize.
(2) Fertilization before Flowering
Fertilization before flowering is applied one week before flowering, usually effective quickly, mainly consisting of nitrogen fertilizers combined with phosphorus and potassium fertilizers. For vigorous tree growth, the use of nitrogen fertilizers can be reduced. For varieties that are very prone to flowering, such as巨峰 (Jufeng), even without top-dressing, they can grow well.
(3) Accelerating Fruit Fertilization
Young fruits rapidly enter the enlargement period. The fruit size is similar to peas. At this time, we need effective nitrogen and phosphorus fertilizers, mainly combined with potassium fertilizers, which can increase fruit size. Fertilization is necessary to promote the growth of flower buds.
(4) Coloring Fertilization
When colored grape varieties start to change color and colorless grape varieties become soft, applying top-dressing is very important. Top-dressing mainly consists of potassium fertilizers, combined with phosphorus and nitrogen fertilizers.
(5) Compensation Fertilization
Timely fertilization after harvest, especially in areas with longer growing periods, is beneficial for accelerating grape maturity and nutrient accumulation.
Root Dressing
Dissolving fertilizers in water and spreading them on leaves allows the fertilizers to enter the plant through leaves, buds, and seedlings, which is an economical, labor-saving, and quick-acting method. It can meet the needs of grape wood in critical periods of fertilizer requirement. Top-dressing is the most effective way to supplement fruit nutrition in orchards.
In summary, if farmers want to increase grape yields, they need to master the correct fertilization methods and do a good job of scientific management. I hope this article can be helpful to you.
