In the middle and south autumn sowing garlic area, mulching is an effective measure to increase the yield of garlic and garlic sprouts. Due to the use of mulch film coverage, the autumn garlic planted in Hebei province has advanced about 200 kilometers to the north and reached the Beijing area. 1. Appropriate sowing time for the suitable sowing date of the film mulching garlic, from the Beijing area to the Shu area, is approximately between the "equinox" and "cold dew". 2. Cangshan garlic is generally used for the selection of good varieties, and Cangshan Po-tree garlic used in Yongnian County where garlic sprouts are mainly produced. 3. Appropriate base fertilizer mulching garlic should be enough base fertilizer, generally with 5000 kg of high-quality farmyard fertilizer, 100 kg of ammonium bicarbonate, 100 kg of superphosphate. Plowing and hoeing. The width is 166 cm. 4. The sowing method is to open 8 furrows in a row with a distance of 20 centimeters and a furrow depth of 3 to 4 centimeters, artificially planted in the furrows, and vertically implant the garlic into the earth. The production of garlic sprouts is mainly from 45,000 to 50,000 plants (plant spacing of 6 to 7 centimeters), and the production of garlic plants is mainly from 25,000 to 30,000 plants (10 to 12 centimeters of plant spacing) per mu. After the soil covered with garlic, the soil thickness is about 0.5 to 1 cm. 5. After watering the film, do not water it after it is planted. Garlic should be drenched in the soil for about 1 week. Then, when the water is poured and the floor is wetted, the self-made simple laying machine is used, and the roll width is 90 cm. 0.004 ~ 0.005 mm garlic weeding film or ordinary film. Push one side of the end of the dumpling and push it forward. Pull the two sides of the film into the soil and pull it tightly to the surface. Then turn the other side and cover the other half of the side of the mulch along the other side. This is actually a step. The son covered two pellicles. Finally, the mandible's membrane was manually cut into the soil. If it is not covered with a special herbicide film for garlic, it is necessary to grasp the herbicide after the first watering, and then cover the film. 6. After 5 to 7 days after the first watering of the ruptured membrane, when there are more coleoptiles on top of the mulching membrane, use a thin rake to sweep the membrane over the membrane to help the garlic break the membrane; the interval is 2 to 3 days thereafter. Sweep it again, and after at least 3 sweeps, put a handful of garlic sprouts out of the mulching film. 7. Pre-winter management of the earth before freezing, pouring frozen water, in order to protect the safe winter garlic. In areas north of Baoding, it is best to sprinkle some grasses in the field to protect the plants from cold. 8. After years of management, the garlic will turn green and then return to Qingshui. Simultaneously, 25 to 30 kg of ammonium bicarbonate is poured into the water. When the mother is rotten, water is poured into the pesticide to prevent garlic sprouts. Before the convulsions, combine watering and then chase ammonium bicarbonate into 50 kg/mu, and pour 2~3 water later.
