Overwintering method of garlic seedling in Yongnian County, Handan City

First, the winter method of garlic seedling raising

1. Before winter, apply compound fertilizer to each mu with water for seedling emergence, and apply sea elf biostimulant to promote root system, condition soil and promote seedling growth.

2, appropriate water control, purple garlic is generally about 5-6 leaves in winter, white garlic is 2-3 leaves, do not have too many leaves before winter to prevent freezing. 99% high-purity potassium dihydrogen phosphate (phosphorus and potassium source bank) can be sprayed on leaves to improve plant nutrition and enhance frost resistance.

3. Before the soil freezes, water the overwintering water in time to ensure the safe overwintering of seedlings. If there is no plastic film cultivation, the border can be covered with firewood to keep warm and cold.

4. In the second year, the weather turned warmer and the overwintering garlic seedlings began to turn green. When the temperature is stable at 1℃-2℃, the covered firewood should be removed. Weeding should be carried out in stages. First, half of it should be removed to expose garlic leaves, so that seedlings can gradually adapt to the external temperature and prevent sudden temperature change from freezing. After the seedlings adapt to exercise, remove all the firewood covered. The temperature is low in early spring, so intertillage should be carried out immediately after the grass is removed to loosen the soil and raise the ground temperature.

5. Sun for 3-5 days after intertillage, and then water with green water. Combined with watering, compound fertilizer can be applied at a rate of 15-25 kg per mu. After the seedlings turned green, the leaves grew vigorously, and Qin Ying watered and fertilized them to promote the growth of the seedlings.

Second, garlic, also known as garlic, garlic, Hu garlic, gourd, single garlic and single garlic, is the general name of garlic plants. Semi-annual herb, Allium in Liliaceae, whose bulbs are used as medicine. Harvest in spring and summer, tie it, hang it in a ventilated place, and dry it in the shade for later use. As the agricultural proverb says, "If you plant garlic for nine months, you will grow nine heads." In June, when the leaves are dry, remove the sediment, ventilate to dry or bake until the epidermis is dry.

Third, growth habits

1, temperature: like cold and cool, the suitable temperature is -5-26℃. The 4-5 leaf stage of garlic seedlings has the strongest cold tolerance, which is the most suitable winter in Miao Ling.

2. Illumination: Garlic in Chunhua begins to differentiate into flower buds and scale buds under long sunshine and high temperature conditions of 1.3 hours or more, which is only suitable for the growth of stems and leaves in short sunshine and cold environment.

3, moisture: like wet and afraid of drought.

4. Soil and nutrition: the requirements for soil are not strict, but fertile loam with rich organic matter, loose air permeability and strong water-retaining and drainage performance is more suitable.
