The fertilization of garlic should be thoughtful and should not be misused.

Abstract: garlic needs a large amount of fertilizer, so fertilization can help high yield.

At present, the weather is getting cooler, and garlic growing areas have begun to grow garlic one after another. Although the price of garlic this year is not ideal, garlic, as a seasoning often eaten in daily life, can be said to be bought by every household, so there are still a lot of farmers growing garlic.

What kind of fertilizer is good for garlic?

If you want garlic to grow well and have a high yield, it is inseparable from reasonable fertilization. What kind of fertilizer is good for garlic? Before solving this problem, we must understand the fertilizer demand in the process of garlic growth, as well as the local planting environment, as well as the variety of garlic. These problems need to be taken into account.

Fertilizer requirement of garlic

First of all, let's take a look at the fertilizer requirements during the growth of garlic. Garlic is a kind of crop which needs a large amount of fertilizer, and the demand for fertilizer is different in different growth stages. Generally speaking, there is the greatest demand for nitrogen fertilizer in the growth process of garlic, followed by potassium fertilizer, followed by phosphate fertilizer, calcium fertilizer, magnesium fertilizer and other fertilizers. The absorption ratio of nitrogen, phosphorus, potassium and calcium is generally 1: (0.25 to 0.35): (0.85 to 0.95): (0.5 to 0.75). And the demand for fertilizer of different elements is also different at different stages of garlic growth.

How to fertilize garlic?

First of all, let's take a look at the fertilization of garlic base fertilizer.

The quality of garlic base fertilizer is related to the later growth of garlic and the overwintering condition of garlic. So applying basic fertilizer is the first step in the successful planting of garlic. Garlic base fertilizer can generally use barnyard manure, chicken manure, ring manure, compost and so on. If you choose stable manure as ring manure, you generally need 2500 to 3000 kilograms per mu, and the amount of barnyard manure is about 4500 kilograms per mu. In addition, about 30 kilograms of special compound fertilizer for garlic and 30 kilograms of superphosphate are needed per mu.

Pay attention to the topdressing of garlic

Garlic topdressing generally has more growth condition, topdressing two or three times. The first time is to fertilize garlic before overwintering. At this time, garlic generally grows to about 25 centimeters and has five leaves. At this time, it is necessary to apply overwintering fertilizer in time to promote garlic to survive the winter safely, generally applying nitrogen fertilizer, and applying about 15 kilograms of urea fertilizer per mu according to the soil conditions.

The second topdressing is usually carried out after the garlic turns green, which is usually carried out before and after the Spring Equinox, and the average temperature is already above 7 degrees. Generally, about 10 kg of nitrogen fertilizer is applied per mu, if the growth of garlic is better, and overwintering fertilizer has been applied, less or no fertilizer can be applied at this time.

The third time is topdressing during the growth period of garlic bolting, which is the key period for garlic growth. Topdressing must be carried out in time to promote the growth of garlic. Generally in the middle of May, about 30 kilograms of potassium sulfate compound fertilizer and 10 kilograms of urea are generally applied.

The fourth time is topdressing after garlic stalk harvest, during this period, the nutrition of garlic began to move downward, which is the most critical period for the growth of garlic. Generally speaking, there are more growth conditions per mu and about 15 kg of potassium sulfate compound fertilizer is applied. (III)
