Field management of garlic in early spring

Garlic is a very popular vegetable in China, which is mainly used as a side dish of all kinds of dishes. Garlic has many functions, and it is also very helpful to human health, so it is welcomed by many people. When we grow garlic in early spring, we need to do a good job in field management. So how exactly should it be done? The following editor will give you a brief introduction to the field management of garlic in early spring. Let's have a look.

1. Raise the ground temperature

Although the temperature gradually picked up in early spring, the ground temperature is still relatively low, and it is easy to appear late spring cold phenomenon. Therefore, when garlic enters the green stage in early spring, we should raise its ground temperature in time. First of all, it is necessary to clean up the sundries on the plastic film and improve the light transmittance of the plastic film, which can effectively improve the low temperature. Then we should carefully examine the situation of the plastic film, and if it is found that the plastic film is damaged, then it should be repaired in time. Avoid the damage of plastic film leading to the invasion of cold air, improve the heat preservation and warming effect of plastic film, and ensure the normal growth of garlic.

2. Fertilizer and water management

Fertilizer and water management in early spring is very important. There are more sunny days in early spring, so we should water and fertilize in the morning when there are more than 4 sunny days in a row. The main fertilizers are flushing fertilization and nitrogen, phosphorus and potassium fertilizer, and the amount of fertilizer is kept at about 20:15kg, combined with watering. If the soil is too dry, it should be watered in time in late March. However, we should pay attention to the watering time, generally can not be watered too early, otherwise it is easy to cause retting root disease, and garlic may also appear secondary growth phenomenon.

Every time we finish watering, we should pay attention to ploughing properly. Improve the permeability of the soil to ensure that water can normally infiltrate into the soil. It can not only increase the ground temperature, but also ensure that the garlic can protect the roots and seedlings normally. When entering early April, always check the growth of garlic. If it is found that the garlic leaves appear yellow tip phenomenon, then it is necessary to re-fertilize in time. Generally speaking, the fertilizer is mainly available nitrogen fertilizer, and the application rate per mu is about 20kg.

3. Disease control

Garlic in early spring is prone to all kinds of diseases if it is not well managed. Among them, leaf blight and gray mold are very common. Therefore, we should pay attention to the management of disease prevention and control in early spring. After the onset of the disease, garlic is prone to appear small white spots on the leaf tip, or light brown spots on the leaf surface. In serious cases, it will lead to the death of the whole leaf, check that there is rot at the base, and the plant will lodge. Therefore, carbendazim or trimethoprim should be used in time for prevention and control.
