Key Techniques for Four-Season Multi-Cutting Cultivation of Stem Garlic

Edible Gardening 0 views
Stem garlic was introduced from Europe and is a perennial crop of the genus Allium in the lily family. Necklace garlic is sown from seed like Welsh onion. Its stems, leaves and scapes resemble those of common garlic, but it is larger and more robust than common garlic, with strong adaptability; it can withstand high temperatures of 40°C and low temperatures of -15°C, and can be sown in spring and autumn in most parts of our country, remaining evergreen all year round. For four-season multi-cutting cultivation, it can be sown from seed like Welsh onion and the seedlings harvested for market, with 1 cutting harvested 60-80 days after sowing, yielding about 2500 kg per mu. If harvesting garlic scapes, seedlings can be raised in summer and autumn, and after 30 days transplanted at a row spacing of 20 cm x 8 cm; scapes bolt in May of the second year after transplanting, with more than 10 tillers per plant, and every tiller can bolt; scapes can be harvested 4-6 times a year, with continuous growth for 5-8 years, during which excess tillers can be pulled out along with their roots for market; the usual yield is about 1500 kg of garlic scapes per mu and more than 5000 kg of stems and leaves.

Sowing and seedling raising are carried out in mid-March in spring and at the end of August and the beginning of September in autumn. Spring-sown seedlings are planted in the field from late May to early June, and autumn-sown seedlings in early October. Spring-sown seedlings are gradually dug up after Frost's Descent and supplied to the market, or they can be stored for winter after harvesting and brought to market in batches or grown as a multi-year crop.
