Garlic is a very popular vegetable in China, which is mainly used as a side dish in various dishes. Garlic is popular with many people because it has many benefits and is good for health. When we plant garlic in early spring, we need to do a good job in field management. So what are the main points of garlic field management in spring?

1. Increase the ground temperature

① Although the temperature rises gradually in early spring, the ground temperature is still low, which is easy to cause inversion. In early spring, garlic should enter the green period, and the ground temperature should be raised in time.

② Removing any sundries in the covering and improving its light transmittance can effectively improve the low temperature. Then check the covering carefully and repair any damage. Avoid the invasion of cold air caused by the damage of plastic film, improve the thermal insulation effect of plastic film, and ensure the normal growth of garlic.

2. Fertilizer and water management

① Fertilizer management in early spring is very important. Because there are many sunny days in early spring, it is necessary to water and fertilize in the morning for more than four consecutive days. Fertilizers are mainly flushing fertilizer and NPK fertilizer, with a dosage of about 20 kg and watering. If the soil is too dry, water it once in late April. However, it is very important to pay attention to the watering time, because it is generally not possible to water early, because it may lead to compost and diseases, and garlic may also develop into secondary growth.

It is very important to cultivate the soil properly after each watering. This improves the permeability of the soil and ensures that water penetrates the soil properly. This will increase the ground temperature and ensure that garlic retains its roots. At the beginning of April, it is very important to check the growth of garlic regularly. If you see yellow tips on garlic leaves, fertilize them again in time. Fertilizer is mainly nitrogen, and the dosage per mu is about 25 kg.

3. Disease control

Garlic is easily infected with various diseases if it is not properly managed in early spring. Leaf blight and gray mold are common. After the onset, garlic is prone to white spots on the tip or light brown spots on the leaves. In severe cases, the whole leaf dies, the base rots and the plant collapses. Therefore, it is very important to control diseases with chemicals such as carbendazim or chloroquine.
