1, seed selection treatment: select improved seeds and soak them to promote germination.

2. Soil preparation and fertilization: loose and fertile soil with rich organic matter is selected, and the land is turned over one week before sowing, and then fertilized for border sowing.

3. Sowing at the right time: Sow when the temperature is stable at 17- 19℃, put the garlic cloves with the tips facing upward evenly in the soil ditch, cover them with soil and plastic film after sowing, and pour enough root setting water.

4. Maintenance management: Do a good job in watering, fertilization and sunshine management.

5. Timely harvesting: when the plant height is 40-50cm and the base is more than 2cm thick, it can be harvested.

First, seed selection treatment

Choose garlic seeds that are full, disease-free and surface-free, and divide them into small petals, and do not damage the bud points. Before planting, the garlic seedlings were separated and divided into three grades according to large, medium and small petals. The separated garlic seeds were soaked in well water (with low water temperature) for 12 hours to break the dormancy of garlic seeds and promote germination.

Second, soil preparation and fertilization

1, choose loose, breathable, fertile, organic-rich soil, whether it is planted in the ground or potted. Land planting should choose fields with soft fertility, turn over the land one week before sowing, and then apply fertilizer for border sowing after drying and raking. Choose a suitable basin for potted plants to ensure permeability, and open a small hole at the bottom of the basin to facilitate drainage.

2. Apply base fertilizer in combination with land preparation. Generally, apply 80- 100 tons of decomposed soil residue manure, 20kg of urea, 50kg of phosphate fertilizer, 50kg of potash fertilizer 15kg or 50kg of high-quality three-element compound fertilizer per mu.

Third, timely sowing

1, try to choose the temperature at 17- 19℃ for sowing. When planting garlic cloves, you can dig a trench in the soil, then put the garlic cloves with their tips facing up evenly in the trench and cover them with fine soil to ensure that the young buds of garlic cloves can be exposed.

2. After planting, sufficient root water can be poured into the soil, so that the soil is in a moist state and garlic cloves can emerge as soon as possible. You can also cover the surface of the soil with a thin plastic film, which needs to be removed when the garlic seedlings grow new buds.

Fourth, maintenance management

1, sunshine: In the early stage, set up a 30cm shed on the border, cover it with a sunshade net or a straw curtain for shading, and remove the shade shed after the seedlings are fully planted. In the later stage, it is necessary to provide full-day sunshine for garlic seedlings so that the plants can carry out photosynthesis normally.

2. Fertilization: Grasp the principle of thin fertilizer and diligent irrigation, provide compound fertilizer rich in nitrogen, phosphorus and potassium for garlic seedlings, and improve the growth rate of plants. When harvesting, fertilize once every harvest.

3. Watering: replenish unpolluted natural water for garlic seedlings to keep the soil moist. Combined with watering, the soil should be cultivated, and gibberellin can be sprayed appropriately when the seedlings grow to a certain height, which is beneficial to the development of stems and leaves.

Five, timely harvesting

Harvest standard of garlic seedlings: the garlic head is about to swell, the plant height is 40-50cm, and the base is more than 2cm thick. Harvest should not be too late, too late garlic seedlings aging or garlic swelling lose commodity value. Every harvest should be fertilized once. Garlic seedling is a perennial vegetable. In order to prolong the supply period and increase the yield, it should be harvested every other plant and listed in batches.
