How to Fertilize a Vineyard Most Efficiently
The editor will share some knowledge about how to fertilize a vineyard most efficiently, let's take a look together.
How to Fertilize a Vineyard Most Efficiently
Based on the growth and development characteristics of grapes throughout the year, in order to achieve high and stable yields, the following fertilization plan is formulated for all stages of grape growth. This fertilization plan emphasizes the application of basic fertilizers and combines reasonable top dressing, aiming for a yield of over 4000 jin per mu. During the top dressing process, the type of fertilizer should be adjusted flexibly according to the growth condition of grapes in each season.
Based on the growth and development characteristics of grapes throughout the year, the following fertilization plan is formulated to achieve high and stable yields.
1. Top Dressing Before Germination
For those who have applied basic fertilizers in autumn: Use calcium nitrate with boron and zinc or ammonium nitrate with calcium or nitrate ammonium potassium 40-80 kg, apply in furrows or with water irrigation or after watering.
For those who have not applied basic fertilizers in autumn: Apply 60-80 kg of nitrophosphate potassium and 25-50 kg of Shibile, mix the fertilizers well before applying in furrows, or use 80 kg of nitrophosphate potassium for water irrigation.
2. Top Dressing Before Flowering
For those who have applied basic fertilizers in autumn: Apply 40-60 kg of nitrophosphate potassium.
For those who have not applied basic fertilizers in autumn: Apply ammonium nitrate with boron and zinc or nitrate ammonium potassium 40 kg and water-retaining loose soil sulfate potassium 18-18-18 50-80 kg.
This period should not use nitrogen fertilizer alone, especially for the Kyoho variety, which can cause blossom and fruit drop when using nitrogen fertilizer alone.
3. Top Dressing During the Young Fruit Stage
Apply 40 kg of high-tower nitrosulfate-based 16-6-18, spray the leaves with calcium gluconate, zinc sulfate, and potassium dihydrogen phosphate, which can effectively prevent large and small berries and physiological fruit drop.
From this period, spray calcium gluconate on the leaves when applying pesticides, or use alternately.
4. Top Dressing During Berry Swelling Stage
Apply 20-40 kg of rare earth nitrate potassium or 30-40 kg of compound microbial inoculant for water irrigation, apply 1-2 times, alternating between the fertilizer and the microbial inoculant.
5. Top Dressing Before Harvest
Apply 40 kg of nitrate ammonium potassium and spray the leaves with calcium gluconate, which can effectively increase the firmness, color, and storage time of the fruit.
6. After Harvest
Apply Tianshi water-retaining loose soil type 18-18-18 or sulfur-phosphorus ammonium 80-120 kg, compound microbial fertilizer 120-150 kg, and Shibile 40-50 kg.
After grapes enter the fruiting stage, special attention should be paid to supplementing calcium fertilizers, as grapes require calcium as much as potassium.
In the annual fertilization process of grapes, emphasis should be placed on applying autumn basic fertilizers, which can effectively replenish the nutritional deficiency of the tree body during the fruiting stage.
We can use the time from after harvest to half before the next year's germination to fully cultivate the roots, adjust the soil structure, and increase the looseness, breathability, and nutritional activity of the soil.
【Summary】This fertilization plan emphasizes basic fertilizers and combines reasonable top dressing, aiming for a yield of over 4000 jin/mu. During the top dressing process, the type of fertilizer should be adjusted flexibly according to the growth condition of grapes in each season.
The above introduction on how to fertilize a vineyard most efficiently is for everyone to learn and understand!
