Choose early-maturing varieties with strong disease resistance, short growth period, wide and soft leaves, high quality and high yield, such as Zhongnong No. 1, Zhongnong No. 3, Quanzhou Garlic and other varieties to grow thick and high-yielding garlic seedlings.
2. Soil preparation and fertilization
Choose plots with flat terrain, good water retention, convenient irrigation and drainage, loose and fertile soil, and plots with food crops or non-onion and garlic vegetables as the first crop. Before land preparation, apply 1500 kg of decomposed organic fertilizer per mu and 50 kg of 45% three-element compound fertilizer per acre, then deep plow and prepare the land. The border is 100-120 cm wide and 20 cm high.
3. Seed treatment
Before planting, select the garlic which is large, round, neat, disease-free and undamaged. Before sowing, soak the garlic cloves in clean water for 12 hours. After removing them, soak the seeds with 200 times solution of 60% benzalkonium suspension seed coating agent + 98% potassium dihydrogen phosphate solution 500 times solution for 30 minutes, remove and dry. Just sowing, it can effectively kill the germs on the garlic seeds, promote the growth of the seedlings, and improve the disease resistance and stress resistance of the garlic seedlings.
4. Sowing seeds at the right time
The sowing date can be determined according to the time to market. The new garlic has a dormant period of 3 months and can be sown from mid-to-late September to early October. Divide the ditch at 10--15 cm row spacing, insert garlic cloves into the soil at a distance of 3 to 5 cm, 2-3 cm deep, and then cover the soil firmly. About 200 kilograms of garlic are needed per mu. After sowing, water and moisturize. Before emergence, cover with 1.4m wide silver and black two-color mulch film.
5. Field management
1. Membrane rupture in time: When garlic emerges, the membrane ruptures in time to ensure the normal growth of garlic.
2. Water and fertilizer management: on the basis of applying plantar fertilizer and watering plantar water, watering and topdressing are generally no longer needed in the early stage. When the garlic seedlings grow to about 15 cm, watering can be combined, and 10 kg of urea per acre is applied in the later stage. 0.3% urea + 30 mg/kg gibberellin solution can be used for foliar spraying.
3. Build a small bow shed: As the temperature continues to drop, to the later stage of growth, before and after the frost, the small bow shed should be built in time and covered with a film to ensure the normal growth of garlic seedlings.
Six, timely harvest
Generally, about 70 days after sowing, when the garlic seedlings grow to a height of more than 30-50cm, they can be harvested in batches according to market conditions.
