Green garlic seedlings are fresh and green garlic leaves as a vegetable supply market. This cultivation method can be carried out at any other time except for summer. The green garlic sprouts are delicious and are high-value seasonings and toned vegetables. There are two ways to cultivate green garlic seedlings: one is not to cultivate soil, the pseudo stems are light; the other is to use the method of soil cultivation to soften the pseudo stems from light and become a vegetable food with white stems and crisp green leaves and bright green leaves. Only the softening cultivation method will be described below. 1. Cultivation season In the southern part of China, softened green garlic seedlings can be planted at any time from late August to March of the next year, and harvested until May. The northern winter is cold, and the open field cultivation is planted from mid-late August to late September, and can be harvested until mid-late November. Cultivation in protected areas can be planted from early October to March next year, and harvested in May. The growth time required from sowing to harvesting the garlic is determined by the temperature conditions. Under the condition of an average daily temperature of 13-20 ° C, it takes 45-50 days from sowing to harvesting. If the temperature is between 7 and 13 ° C, it takes 75-80 days; at 0-7 ° C, the seedlings stop growing, but are not affected by freezing. Because the temperature conditions required for the growth of garlic seedlings are not high, the protection facilities with simple insulation properties are not well used in cultivation, such as wind barrier impotence, small arch shed, plastic greenhouse, or in the airway of the north wall of the solar greenhouse, or Cultivated on the window sill of the family. 2. Variety Selection Various garlic varieties can be used to cultivate softened green garlic seedlings, and all varieties are suitable for cultivation of green garlic seedlings. In the past, small petal varieties were used, such as the cultivation of green garlic seedlings with dog tooth garlic. This method saves garlic and has low cost, but the garlic is slender, the yield is low, and the quality is not good. In view of this shortcoming, at present, many varieties of large petals are used to cultivate green garlic seedlings. When the large-flowered species are cultivated for green garlic seedlings, the amount of seed is large, the cost is slightly higher, but the yield is high, the quality is good, and the growth is strong. There are special varieties for cultivating garlic seedlings in China, such as the whole state meat garlic in Guangxi. The garlic cloves are light but fat, and the growing garlic seedlings are strong and high-yielding. When cultivating green garlic seedlings in early autumn, the varieties with short dormancy period should be selected so as to sprout early after sowing. In Shandong Province, it is appropriate to use purple garlic. 3. Seeding is made in the open field or in the protected area, and is made into a flat raft of 1.5-1.7 meters wide. The organic fertilizer used in the simmer is 45,000 kg per hectare and 10 cm in shallow. Garlic treatment is carried out in the same autumn. The petal can be sown with skin, or it can be soaked in clear water for one night to peel off the foreskin and then sown. After peeling, the seedlings are quicker and more neat. When planting, put the garlic petals in a vertical arrangement on the raft. After the broadcast, cover the soil 3 cm, pour the water and then 1-2 cm. 4. Bing soil softening appropriate soil can increase the length of pseudo-stem of green garlic seedlings, improve product quality, and have the effect of softening the pseudo-stem. When the garlic seedlings are basically out and the leaves are not yet unfolded, the water is poured once. After the water has been infiltrated, it is covered with a layer of sand or horse dung and grass, about 5 cm thick. If the garlic grows strong and grows, after the soil is covered, a layer of soil can be sprinkled to ensure that the length of the garlic stem is 10-15 cm. 5. Field Management Softening Green garlic seedlings mainly rely on the accumulation of nutrients in the seedlings. If the base fertilizer is sufficient in the nursery, the topdressing period does not need to be topdressed. In the protected area, the temperature is lower and the water evaporates less. Therefore, after pouring water once before the first soiling, it is generally unnecessary to re-water. When planting in open field, it should be watered several times from sowing to harvesting. It is necessary to gently pour water before emergence, which can reduce the ground temperature, keep the soil moist, and promote the rooting of garlic seedlings and early emergence. After the garlic is ready, the urea can be applied with water, 150 kg per hectare. 15 to 20 days before harvesting, urea can also be applied once. Green garlic seedlings that are exposed to the winter, should be poured over winter water before winter. 6. Temperature management When planting softened green garlic seedlings in protected areas, proper temperature management is required. Keep 20-25 ° C inside the protective ground before emergence. After the emergence of the seedlings, keep the temperature below 20 °C during the day, and reduce the temperature by more than 20 °C; not less than 5 °C at night. The temperature should be lowered 4-5 days before harvest, about 15 °C during the day. The temperature of garlic in the growing season is too high, it is easy to occur long and fall, affecting product quality. The temperature is too low, which causes growth retardation and affects the market. Therefore, in the late autumn and early winter, when the outside temperature is high, ventilation and cooling should be strengthened. In the deep winter and cold season, you should pay attention to the rigid plastic film, and cover the grass to keep warm. 7. The standard for harvesting high-quality softened garlic seedlings is that the pseudo-stems are long and thick, the sizes of the trees are relatively neat, the leaves are tender and not long, and there are no dead leaves and dry leaves. When harvesting, the seed petals can be pulled up and bundled and washed. It can also be cut with a knife about 1 cm from the ground. Do not injure the garlic cloves when harvesting, and then add fertilizer and water after growing new leaves; promote plant growth and facilitate the second knife. At the third harvest, the company was uprooted. Disclaimer: Some articles on this website are transferred from the Internet.
