Key points of standardized cultivation techniques of garlic sprouts

Garlic sprouts, also known as green garlic (garlic yellow when there is no light). The flower moss of garlic consists of two parts: the flower stem (moss stem) and the involucre (bract). The moss bud is the involucre at the top of the flowering stem of garlic, which contains underdeveloped inflorescences. The garlic seedlings with good quality should be fresh and tender, the plant height is about 35 cm, the leaves are bright green, neither yellow nor rotten, the hairy roots do not wither, and the spicy taste is strong. It is the green seedling that garlic seedling develops to a certain period, it grows in the farmland, it has the spicy taste of garlic, with its tender garlic leaf and leaf sheath for consumption. Garlic seedlings are rich in vitamin C and nutrients such as protein, carotene, thiamine, riboflavin and so on.

Varieties of garlic seedlings

There are many varieties used for bolting or both bolting and valves. the common local varieties are Linying garlic, Chaohua garlic, Kaifeng garlic, Luoyang purple garlic, Cixian Li garlic, Shanghai Jiading garlic, Hebei Anguo garlic, Shandong Cangshan garlic, Jiangxi Duchang red garlic, Chengdu Jintang red garlic, Anhui Lai'an garlic and so on. The garlic bolts of these garlic are more developed, but the garlic head is smaller. Garlic for bolting has strict requirements for light, so it must be tested first and then popularized, and it should be introduced from areas with similar conditions, so that there are more chances of successful introduction.

Garlic seedlings of the four seasons like fertilizer, which is especially suitable for farm manure and chemical fertilizer. The output is more considerable under the condition of sufficient fertilizer and water. Garlic seedlings of the four seasons have strong disease resistance and generally have no diseases and insect pests. if there are diseases or insect pests, you can refer to the prevention and control methods of garlic diseases and insect pests. Where it is too cold in winter, it is appropriate to sow seeds in spring and summer, and protective measures can be taken according to the situation after winter. The method is to cut off the ground before frosting, cover it with dung or wheat straw after pouring enough overwintering water, and then dig out the roots of the four seasons garlic seedlings and put them in indoor sand storage, and transplant them after thawing in the spring of the following year.

Key points of standardized cultivation techniques of garlic seedlings

1. Application of sufficient base fertilizer: 5000 kg of organic fertilizer and 40 kg of potassium sulfate were applied per mu before planting, and 25 cm deep ploughing and fine soil preparation were made after fertilization. 2. Seed treatment: the diseased, dry rot and injured garlic seeds are removed before sowing, and the garlic cloves are graded according to large, medium and small grades. Three days before sowing, the garlic cloves were packed in a container according to grade and soaked in water, and the water was changed once a day to make the garlic fully absorb water and promote germination. This operation is also beneficial to adjust the farming season and facilitate hierarchical management. Before sowing, garlic seeds should be mixed with sifted calcium superphosphate to meet the demand for phosphorus during garlic sprouting, with 30 kilograms of superphosphate per mu of garlic seed. 3. Planting at the right time: the temperature should be 17 ℃ and 19 min. Before sowing, make a bed 1.5m wide, trench with a row spacing of 20ml / 23cm (10cm deep), and then put garlic cloves with 55000 plants per mu according to the plant spacing of 5cm. The seeds should be arranged at different levels when sowing, so as to facilitate management. Garlic seeds should be kept upright and uneven at the top and bottom, so that the thickness of the covered soil is the same and the emergence of seedlings is ensured. The planting depth is 6 mi 7 cm, and the thickness of the soil cover is generally suitable for the tip of buried garlic cloves. 4. Post-planting management: pour water once after planting to promote the germination of garlic cloves. Water the seedlings again after emergence, and after the land is dry, hoe to preserve soil moisture to prevent soil consolidation. Each time the soil is watered, the ridge is as high as 5ml / 7cm. When the seedlings grew to the 3-leaf stage, the whole plant was sprayed with 20 mg / kg gibberellin solution to promote the growth of the stems and leaves; when the seedlings grew to the 4-leaf stage, the stems and leaves were sprayed with 0.8% sugar water, once every 6 days, 3 times in a row. 5, timely harvest: the Beginning of Winter can first sell first-class seedlings according to the market situation, and pay attention to the removal of fibrous roots and old leaves during harvest. After the temperature dropped to 0 ℃, the rest were cultivated in a small arch shed. If it is put on the market after January of the following year, the small arch shed should be covered with grass to prevent the cold.
