Garlic growth habits

1, temperature: like cold, suitable temperature in-5-26℃. Garlic seedling 4-5 leaf stage cold tolerance is the strongest, when the most suitable winter seedling ridge.

2. Light: Garlic that has completed spring flowers begins to differentiate flower buds and scale buds under long days and higher temperatures for more than 13 hours. In short days and cold environments, it is only suitable for stem and leaf growth.

3. Moisture: wet and afraid of drought.

4. Soil and nutrition: The requirements for soil are not strict, but fertile loam rich in organic matter, loose and breathable, and strong water retention and drainage performance is more suitable.

The reason for garlic hair.

1. The soil is too shallow, the garlic is exposed, and the sun is exposed;

2. In the late stage of bulb expansion, if there is too much rain, the soil is too wet;

3. Harvest too late.

Garlic scattered head response measures

1. Drainage should be done well in the late stage of bulb expansion. Drain water in time after rainfall, and do not irrigate water unless it is dry, so as to avoid excessive soil moisture.

2. Timely harvest. 18-20 days after harvest is the optimum harvest time of garlic sprouts. The standard of suitable harvest time is that most leaves of the plant are dry, the upper leaves are faded to the tip of the leaf, the plant is in a soft state, the plant is pressed from the base to one side, and it is a mature sign when it is not fragile and flexible.

3. Drying in time after harvest, covering garlic heads with garlic leaves, focusing on drying garlic stalks and garlic leaves to reduce water content in the body, so that the base of leaf sheath and protective scales gradually lose water and become dry. Rain and moisture proof during storage.
