What are the key points of standardized cultivation techniques for garlic sprouts?

Garlic sprouts, also called green garlic (they become "garlic yellow" when kept from light). The flower stalk of garlic consists of two parts: the flower stem (scape) and the spathe (the bract). The spathe is the involucre at the tip of the garlic flower stem and contains an incompletely developed inflorescence. Good-quality garlic sprouts should be tender and fresh, with a plant height of about 35 cm, bright green leaves that are neither yellow nor rotting, white fibrous roots that are not withered, and a fairly strong pungent flavor. They are the young seedlings of garlic at a certain stage of development, grown in farm fields, and they have the spicy flavor of garlic; their tender garlic leaves and leaf sheaths are eaten. Garlic sprouts are rich in vitamin C as well as nutrients such as protein, carotene, thiamine and riboflavin. ⟦4 <p>Garlic sprouts, also called green garlic (they become "garlic yellow" when kept from light).

Common local varieties include Linying garlic, Chaohua garlic, Kaifeng garlic, Luoyang purple-skin garlic, Cixian LItai garlic, Shanghai Jiading garlic, Hebei Anguo garlic, Shandong Cangshan garlic, Jiangxi Duchang red garlic, Chengdu Jintang red garlic, and Antai garlic from Lai'an County, Anhui, among others. These garlics have relatively well-developed scapes but smaller bulbs. Scape-type garlic has strict light requirements; when introducing it, you must first test and then promote it, and it should be introduced from areas with similar conditions, so that the chance of success is greater.</p><p>Four-season garlic sprouts like fertilizer, and are especially suited to farmyard manure as the main fertilizer, with chemical fertilizer applied as well. When fertilizer and water are abundant, the yield is even more considerable. Four-season garlic sprouts have strong disease resistance and generally have no pests or diseases; if diseases or pests appear, the control methods for garlic can be used as a reference. In places that are too cold in winter, it is best to sow in spring and summer, and after winter begins, protective measures can be taken according to the situation. The method is: cut off the aboveground part before frost, water thoroughly for overwintering, then cover with manure soil or wheat straw so they can overwinter safely; alternatively, dig out the root clumps of the four-season garlic sprouts, store them in sand indoors, and transplant them after the ground thaws the following spring.</p><p>Key points of standardized cultivation techniques for garlic sprouts</p><p>1. Apply sufficient base fertilizer: before planting, apply 5000 kg of organic fertilizer and 40 kg of potassium sulfate per mu. After fertilizing, plow 25 cm deep and prepare the land finely. 2. Seed treatment: before sowing, remove diseased, dry-rotted and damaged garlic seeds, and when breaking apart the cloves, grade them into three sizes: large, medium and small. Three days before sowing, place the cloves by grade in containers and soak them in water, changing the water once a day, so the garlic seeds absorb enough water and germinate well. This step also helps adjust the farming schedule and facilitates graded management. Before sowing, mix the garlic seeds with sieved superphosphate to meet the phosphorus demand of the cloves during germination; use 30 kg of superphosphate per mu of garlic seeds. 3. Plant at the right time: a temperature of 17-19°C is suitable. Before sowing, make beds 1.5 m wide, open furrows at a row spacing of 20-23 cm (furrow depth 10 cm), then place the garlic cloves at a plant spacing of 5 cm, planting 55,000 plants per mu. When sowing, place the seeds by grade to make management easier. When placing the garlic seeds, keep them upright, aligned at the top but not at the bottom, so that the soil cover is uniform and the seedlings emerge evenly. The planting depth is 6-7 cm, and the soil cover is generally just enough to bury the tips of the garlic cloves. 4. Management after planting: water thoroughly once after planting to promote germination of the cloves. After the seedlings emerge, water once more to promote seedling growth; after the soil surface dries, hoe to conserve moisture and prevent soil crusting. After each watering, cultivate soil once so the ridges reach 5-7 cm high. When the seedlings reach the 3-leaf stage, spray the whole plant with a 20 mg/kg gibberellin solution to promote stem and leaf growth; when the seedlings reach the 4-leaf stage, spray the stems and leaves with 0.8% sugar water, applying once every 6 days for 2-3 consecutive applications. 5. Harvest at the right time: before the Start of Winter, the first-grade seedlings can be sold first according to market conditions; when harvesting, be careful to remove the fibrous roots and old leaves. After the temperature drops below 0°C, build small arched sheds over the remaining plants for insulated cultivation. For those extended for sale after January of the following year, add straw mats over the small arched sheds to protect against the cold.</p>
