What kind of fertilizer makes garlic grow the fastest and most vigorously?
Garlic requires a variety of nutrients during its growth process. By using different types of fertilizers in a proper combination, it can grow faster and more vigorously.
Below is a list of fertilizers suitable for different growth stages of garlic:
Base fertilizer:
Base fertilizer is the foundation for the growth of garlic, providing continuous nutrient supply throughout its entire growth cycle. It should be mainly composed of organic fertilizers, with chemical fertilizers serving as a supplement.
● Organic fertilizers: Common examples include farmyard manure (such as decomposed pig manure, cow manure, chicken manure, etc.), compost, and green manure.
These organic fertilizers are rich in various nutrients and abundant organic matter. They can improve soil structure, enhance soil fertility and water-holding and nutrient-retaining capabilities.
Generally, 3,000 - 5,000 kilograms of well-rotted farmyard manure can be applied per mu (Chinese unit of land area).
● Fertilizers: Mainly include nitrogen fertilizers, phosphorus fertilizers and potassium fertilizers.
Common nitrogen fertilizers include urea, phosphorus fertilizers such as superphosphate, and potassium fertilizers like potassium sulfate.
Generally, 15 - 20 kilograms of urea, 50 - 60 kilograms of superphosphate and 15 - 20 kilograms of potassium sulfate can be applied per mu (Chinese unit of area measurement).
Fertilizer application:
Apply fertilizers at different growth stages of garlic to meet its needs for growth and development.
● Seedling Promotion Fertilizer: After the garlic seedlings have emerged, if the base fertilizer is insufficient or no seed fertilizer has been applied, a single application of seedling promotion fertilizer can be made.
The main fertilizer is nitrogen fertilizer. Generally, 5 - 8 kilograms of urea or 10 - 15 kilograms of ammonium sulfate can be applied per mu (Chinese unit of area).
● Revitalizing fertilizer: It is typically applied when the temperature rises in spring and the garlic leaves start to grow and the root system begins to elongate.
The main fertilizer is nitrogen fertilizer, combined with an appropriate amount of phosphorus and potassium fertilizers. For each mu of land, apply 10 - 15 kilograms of urea and 5 - 10 kilograms of potassium sulfate.
● Garlic shoot fertilizer: Apply fertilizer when the garlic shoots begin to differentiate. This is a crucial period for garlic growth, and the demand for nutrients is high.
Nitrogen fertilizer should be the main component, along with the application of phosphorus and potassium fertilizers. Each acre can be fertilized with 15 - 20 kilograms of urea and 10 - 15 kilograms of potassium sulfate.
● Bulb Enlargement: After harvesting the bulbs, it is the crucial period for bulb enlargement. At this time, a large amount of potassium fertilizer should be applied, along with an appropriate amount of nitrogen fertilizer.
Generally, 15 - 20 kilograms of potassium sulfate and 5 - 10 kilograms of urea should be applied per mu (Chinese unit of land area).
☆. Foliar fertilizer:
During the middle and late stages of garlic growth, nutrients can be supplemented through foliar spraying, which can quickly provide nutrients to the plants, enhance the photosynthesis of the leaves, and increase the yield and quality of garlic sprouts and bulbs.
● Trace element fertilizers: such as borax, zinc sulfate, and ammonium molybdate, can enhance the stress resistance and quality of garlic.
Generally, during the growth period of garlic sprouts and the period of bulb enlargement, a 0.2% - 0.3% borax solution or a 0.1% - 0.2% zinc sulfate solution should be sprayed every 7 - 10 days.
Plant growth regulators: such as brassinolide, can regulate the growth and development of garlic and enhance its stress resistance.
Generally, during the middle and late stages of garlic growth, apply a 0.01% - 0.05% solution of brassinolide, spraying it every 7 - 10 days, and repeat this process 2 - 3 times.
