Pollution-free garlic cultivation technology

   

Choose the best species to choose Cangshan white skin garlic, Yongnian white skin garlic, these varieties of garlic head hypertrophy, the skin is white. Generally, each head has 7~10 petals, and the single head weighs about 45g. It has quick germination, golden yellow tip, good quality and high yield. It is an ideal garlic variety for planting garlic.

The construction of the warm garlic garlic has a short growth period and a wide range of temperature adaptation, and can grow under the condition of 12 ° C ~ 30 ° C. The production site should choose the leeward sunny and high-lying plots to improve the warming temperature and reduce the freezing damage. When the outside temperature rises, it can cool the wind well. It is produced by the use of earthen warm concrete. The height of the warm concrete is generally 2~2.5 meters, the depth of the ground is 1 meter, the height of the exposed ground is 1~1.5 meters, the length of the raft is 7 meters, and the width of the raft is 7 meters. Surrounded by brick walls, topping the top, using cement columns as the main beam, the wooden poles are placed on the cement columns to make the tweezers, and the wire is fixed firmly. Under the scaffolding, support the two columns (three per row) of cement columns, and then place corn stover or grasshopper on the shelf. The top cover is covered with a thickness of about 40 cm. Leave a wind venting window at each of the four corners, and dig a 50 cm wide and 1.4 m high entrance and exit on the side of the raft. The entrance and exit should be covered with a curtain to prevent wind and light. The cultivated bed soil is preferably rich in organic loam, the thickness of the soil layer is 10~12 cm, and the garlic is placed after the flattening.

Before the sowing, the garlic is stripped of the outer skin of the garlic bulb, the basal plate and some or all the garlic skin to facilitate water absorption and gas exchange. The low temperature treatment of 0 ° C ~ 4 ° C before sowing, can be released in advance. In addition, soaking in water for a day and night before sowing, so that the garlic can fully absorb water and accelerate germination. When planting, try to use dense planting methods to plant the garlic one by one in the cultivation pot. Immediately after sowing, cover 3~4 cm of soil and pour water once. The gauze is covered 20 cm above the kneading surface, and the four corners are fixed with wooden posts to support the garlic plants to prevent lodging and improve quality.

The management of garlic noodles mainly uses the nutrients stored in garlic bulbs to transform into fresh leaves for consumption. The key to management is to timely and appropriate watering, control soil moisture and promote rapid growth of leaves. The soil is too dry, the leaves grow slowly, affecting the quality and yield of garlic, but under confined conditions, such as air, soil moisture is too large, and garlic rot is easy to occur, so the number of watering should be minimized. Generally, it is poured once after planting to maintain high humidity to ensure the rapid emergence of garlic. In the future, the water can be flexibly watered according to the outside temperature, soil moisture, and garlic yellow growth conditions, and the humidity in the warm sputum cannot be too high. In the early stage of growth, the amount of water sprayed is small, and gradually increases in the later stage. Before the harvest, the appropriate amount of water is poured once, which not only ensures the yield and quality of the garlic, but also lays a foundation for further growth after harvesting. After entering the Lidong Festival, the outside temperature is significantly reduced. It is necessary to heat the stove in the warm shovel (you can make a small earthen stove) to increase the temperature and keep it growing normally. When the temperature exceeds 20 °C during the day, the wind should be cooled to prevent the heat from growing.

Harvest at the right time when the garlic height reaches 35~45 cm. It usually takes 25 days from the planting of garlic to the cutting knife, and it can take the second knife in about 20 days. Cut it when harvesting, don't pull it up. The harvested garlic is tied in bundles and aired in the sun to make the garlic leaves turn from white to golden yellow. In the production process, the sowing date should be flexibly determined according to the harvest period to achieve the best benefit.
