Early autumn garlic cultivation technology
1. Apply enough base fertilizer. Before planting, apply 5,000 kg of organic fertilizer and 40 kg of potassium sulfate. After fertilization, plow 25 cm and finely prepare the ground.
2. Seed treatment. Before the sowing, the garlic with the disease, dry rot and wounded will be removed, and the garlic cloves will be graded according to the three levels of large, medium and small. 3 days before sowing, the garlic cloves are immersed in a container and soaked in water, and the water is changed once a day to make the garlic fully absorb water and promote germination. This step also facilitates adjustment of farm time and ease of hierarchical management. Before sowing, the garlic should be mixed with sieved superphosphate to meet the demand for phosphorus when the garlic cloves germinate, and 30 kg of superphosphate is used per acre of garlic.
3. Planting at the right time. The sowing period is preferably when the local average daily temperature is between 17 °C and 19 °C. Before planting, make a 1.5-meter-wide shovel, ditch with a line spacing of 20 to 23 cm (ditch depth 10 cm), and then place the garlic cloves at a plant spacing of 5 cm, with 55,000 plants per mu. When planting, it should be graded for easy management. Garlic should be kept upright when placed, so that the thickness of the soil is the same, to ensure that the seedlings are neat. The planting depth is 6-7 cm, and the thickness of the covering soil is generally suitable for burying the top of the garlic clove.
4. Management after planting. After planting, pour water once to promote the sprouting of garlic cloves. After the emergence of the seedlings, the seedling water is poured once again, and the soil is dried and then padded to prevent soil compaction. Each time the water is poured once, the ridge is as high as 5 to 7 cm. When the seedling grows to the 3-leaf stage, the whole plant is sprayed with 20 mg/kg gibberellin solution to promote the growth of stems and leaves; when the seedlings grow to the 4-leaf stage, the stems and leaves are sprayed with 0.8% sugar water, and sprayed once every 6 days. , even spray 2 to 3 times.
5. Harvest at the right time. Before the winter, you can sell the first-grade seedlings according to the market conditions, and pay attention to remove the roots and old leaves when harvesting. After the temperature drops to 0 °C, the remaining small arch sheds are kept in heat preservation. After being extended to the market after January of the next year, it is necessary to cover the grass outside the small arch shed to prevent cold.
