What is the best fertilizer for grapes
Let me tell you about the knowledge related to the best fertilizer for grapes, and then let's get to know it together.
What is the best fertilizer for grapes
In the northern regions, grape planting can be fertilized annually in September-October, while in the southern regions, fertilization is done between October and November, which is beneficial for the promotion of new roots and the increase of nutrient reserves in the tree body. Top-dressing for grapes is usually done by applying a fast-acting nitrogen fertilizer about ten days before flowering, and potassium fertilizer is applied at the beginning of July. The purpose of top-dressing at different stages is different, with both base and top dressings being nitrogen-based, but the proportions during fertilization should be appropriate.
Grape fertilization timing
1. Fertilization is carried out before the grape roots enter the second growth peak, with the northern regions fertilizing in September-October each year and the southern regions between October and November, which is beneficial for the promotion of new roots and the increase of nutrient reserves in the tree body.
2. The annual roots of grapes are weak, so a small amount of chemical fertilizer can be applied, and a little organic fertilizer can be applied every two months to promote healthy growth.
3. Top-dressing for grapes is usually done by applying a fast-acting nitrogen fertilizer about ten days before flowering, and potassium fertilizer is applied at the beginning of July. The purpose of top-dressing at different stages is different.
What type of fertilizer for grapes
When fertilizing grapes, both base and top dressings are nitrogen-based, which can promote more vigorous leaf growth, but the proportions during fertilization should be appropriate to avoid single fertilization.
Generally, the treatment of grape fertilization mainly supplies the basic nutrients needed during the entire growth period of grapes, creating good soil conditions for crop growth and development, and can also improve the soil and increase soil fertility.
Grape fertilization methods
1. Base fertilizer: Grapes are fertilized with base fertilizer in mid-September to mid-October, with 6-8 cubic meters (5000-10000 kg) of decomposed pig, chicken, or cow dung per mu, plus 15 kg of diammonium phosphate.
2. Top dressing: The first top-dressing for grapes is done before germination, mainly with N fertilizer, and the amount of fertilizer should account for 1/2 of the annual top-dressing N fertilizer. A narrow trench 10-15 cm deep is dug 30-40 cm away from the plant, and after fertilization, water is applied and soil is covered.
Precautions for grape fertilization
The soil nutrients in grape planting are leached severely, so fertilization should be done in small amounts and multiple times, with attention to reducing the amount of irrigation water. After the fruit is harvested, within one month, base fertilizer needs to be applied.
