Second, erected bed (a) the location of the bed and materials. The position of the bed is divided into 3 parts: the front and rear of the greenhouse are shorter, can take 2 shelves, the middle is higher, can take 3 shelves. The distance between each bed is 80 cm. Beds are made of wood, straw, old plastic film, iron wire and a small amount of red brick. (b) Laying up the bed. The first floor is 10 centimeters from the ground floor of the greenhouse, and several walls of 6 to 7 centimeters wide are laid, each wall is 1.2 to 1.6 meters long, and then the wood frame is used to form a bed frame of 1 to 3 meters wide (unlimited length). The distance between the rods is preferably 20-30 cm. After the bed frame is over, an old plastic film (for water retention) is laid on top and the film is covered with 6 cm thick sandy loam soil. The second floor is based on the first floor, 80 to 100 cm from the first floor with a wooden pole abduction frame, bed width of 1 meter, the bed frame is tied and then covered with 6 cm thick straw, the straw is covered with a layer of old plastic The film was covered with 6 cm thick sandy loam soil and the soil was photographed. The third floor is 60 cm high from the second floor and is framed by wooden poles. The bed is 80 to 90 cm wide. After the bed frame is well-knotted, a 6-cm-thick stalk of straw is spread on the stalk. An old plastic film is placed on the stalk. The film is covered with 6-cm thick sandy loam soil and the soil is tamped.

Third, cultivation management (a) the choice of garlic. Large varieties with large heads, many flaps, and short dormancy periods were selected, and the varieties had a rapid emergence and high yield. (b) Treatment of garlic seeds. Garlic with a large container, add 20 °C water soak for 30 hours, so that the garlic water swelling, soaked out after the drain drain stuffy stuffy, and then dig out the stem plate. If the production volume is large, the stem plate may not be dug, but it must harvest two knives. (c) put garlic pressure sand. 15 kg of garlic per square meter. The tighter the garlic is, the tighter the space between the garlic is filled with loose garlic. After the garlic is covered, cover a 3cm thick fine sand, then make a photo, and take a shot every 3 days. (d) Moisture management. Garlic seedling watering, water temperature not lower than 15 °C, it is best to use 20 °C water, so as not to reduce the temperature of the bed. Pre-growth (after planting garlic) pouring water, the middle of the growth period (15 to 16 cm in height) pouring water, pouring water in the late growth period (4 days before harvest). Because the garlic seedlings are exposed in the space, the water is scattered and lost quickly. The number of watering depends on the dry and wet conditions of the bed soil. (e) Temperature management. Keep the greenhouse membrane surface clean and improve light transmission. After planting garlic, the daytime temperature is controlled between 24°C and 26°C, and the nighttime temperature is controlled between 20°C and 22°C; after Miao Qi, the daytime temperature is controlled between 22°C and 24°C, and the nighttime temperature is controlled between 18°C ​​and 22°C; At 15 cm, the daytime temperature is controlled between 20°C and 22°C, and the nighttime temperature is controlled between 16°C and 18°C. During harvest, the daytime temperature is controlled at 18°C ​​and the nighttime temperature is controlled between 14°C and 16°C.

Fourth, timely harvest When the garlic grows to 35 cm, seedling leaves slightly tilted, it should be harvested in time. The first knife can be cut 20 days after planting garlic seedlings. After the first knife is cut, the new seedlings will be re-watered after the knife roots are healed, and the second knife will be cut when the seedlings grow to 30 centimeters after 20 days.
