Garlic can be treated for the first time when it turns green at the vernal equinox.

According to the growth and development of garlic and the characteristics of fertilizer demand, it is generally based on matured organic fertilizer (agricultural fertilizer) supplemented by chemical fertilizer. Before sowing and cultivation, base fertilizer should be applied first. Usually 1000-2000kg organic fertilizer and 50kg ternary compound fertilizer are needed per mu. Top dressing of garlic is usually based on nitrogen fertilizer, combined with phosphorus fertilizer and potassium fertilizer. Usually, it can be topdressing in different periods, which can be divided into green turning period, garlic tomb extension period and garlic head growth period.

During the period of turning green, some insecticides can be used at this time, and topdressing can be carried out when garlic seedlings turn green. In spring, the average daily temperature reached about 7 C, and topdressing began. Usually, 10- 15 kg nitrogen fertilizer or 1000- 1500 kg organic fertilizer is applied per mu. Garlic seedlings are generally harvested when they grow to about 20 cm, so it is not necessary to consider garlic germination and extension period and garlic head growth period in topdressing.

The steps of hydroponics garlic:

Material preparation: fresh garlic, clear water, rooting powder, hydroponic container and nutrient solution.

1, garlic stem removal

Garlic is mostly planted in the soil, but you can buy fresh garlic at ordinary times. First, you need to treat its skin, remove the roots of garlic, wash them with water, and apply rooting powder to the removed roots.

2. Prepare the container

When talking about how to raise garlic in water, it is necessary not only to treat garlic, but also to prepare suitable containers for hydroponics. Usually, cups, plates and other containers can be used. For hydroponics, garlic needs to be replaced according to the growth needs, so it is necessary to prepare containers with larger caliber.

3, hydroponic rooting

First of all, you need to put the processed garlic into a container, and you need to inject a proper amount of water into it to drown the garlic for a quarter.

4. Management measures

Every time garlic takes root in hydroponics, it must be given a better water source in time, just change the water every 3 ~ 4 days. You also need to drop a few drops of nutrient solution into the water and carefully maintain it in the shade. Just wait patiently for garlic to take root and sprout. After taking root and sprout, it can be maintained in astigmatism.
