Fertilization techniques of garlic in spring

Garlic is one of the common seasoning vegetables. There is a great demand for fertilizer and water in the process of planting. In order to achieve high yield and high quality, it is necessary to take spring topdressing seriously. So how to fertilize garlic in spring? Let's get to know it with the editor.

1. Returning to green fertilizer

When the temperature gradually picks up in spring, garlic will also enter the green stage. Generally, when the temperature exceeds 7 degrees, garlic begins to dabble in the green stage. For the land with sufficient base fertilizer, there is no need to top fertilizer at this time, only after the garlic turns green. Appropriate foliar fertilizer and growth regulators can be sprayed. The most commonly used are potassium dihydrogen phosphate and brassin, which can enhance disease resistance and stress resistance. in addition, there is often late spring cold in spring, and spraying them can also prevent low temperature freezing injury.

2. Garlic bolting fertilizer

Garlic bolting fertilizer is generally applied before and after the Qingming Festival, when the garlic plant enters the rapid growth period, and the garlic stalk in the root has begun to differentiate and grow, at this time, if the base fertilizer is sown, it needs topdressing in time. At the same time, it is also a period of large water demand for garlic. 2-3 kg urea can be applied with watering. Do not apply too much, so as not to cause damage to the root system, but also cause the phenomenon of yellow leaves in garlic prematurely, because nitrogen will also be converted into ammonia, which will burn the root system and reduce production in a large area because of the barrier of plastic film. As for the land with sufficient base fertilizer, there is no need to apply fertilizer this time, just spray the right amount of insecticides to prevent garlic maggots, pesticides must be sprayed through.

3. Bulb expansion fertilizer

This fertilization can be flushed with water before and after garlic stalk harvesting. Generally, 2.5 kilograms of urea and 2 kilograms of potassium dihydrogen phosphate per mu can be harvested after irrigation, and because garlic bolts are just watered at this time, the water is sufficient and the yield is high. After the garlic stalk is harvested, the nutrition of garlic begins to flow back to the root system, forcing the underground bulb to grow, and those with insufficient water can be watered in time. And 2.5 kilograms of urea per mu, after garlic stalk harvest, watering is the earlier the better, it should be noted that 7-10 days before harvest stop watering and fertilization.
