Don’t soak garlic in water.
Garlic planting techniques:
1. Preliminary planting
1. The depth of soil preparation is generally about 20cm, and it needs to be carefully tilled, leveled, and raked , there is no obvious lump, and it reaches "even, loose, broken, and clean". The length of the border is determined according to the water source. The border can be 80-100m long and 4.2-4.4m wide; it can also be 40-50m long and 4.2-4.4m wide.
2. Select seeds, peel and break the cloves manually, remove the trays and stems of the garlic, and grade them according to large, medium, small and heart. Small garlic cloves are processed according to specific conditions. The seed selection requirements are pure white without red veins, no scars, no saccharification, and no smooth skin. The principle requires that the weight of each pill is about 5g. Seed size is key to achieving high yields.
3. Sow garlic at the right time. Sow garlic at the right time. The planting time is at the end of Bailu and the beginning of autumn equinox (end of September and beginning of October), and the temperature is about 17°C. Dry garlic cloves for 1 to 2 days before sowing.
4. Reasonable and dense planting, the general row spacing is 20cm, the plant spacing is 16-17cm, and there are about 20,000 plants per 667 square meters. The method is to use a rake or ditch opener to make a trench about 5cm deep, and cover the garlic with about 1cm of soil after planting.
2. Field management
1. Irrigation of garlic requires a relatively large amount of water, and generally requires 4 waterings during the entire growth period. ⑴ Covering water: Garlic needs to be watered in time after sowing, watering enough to ensure that no one plant leaks, and 100 cubic meters of water per 667 square meters. This water not only meets the needs of garlic planting, but also provides convenience for covering with mulch.
⑵ Water for strong seedlings: Watering is usually done around early April or when the ground temperature is above 15℃.
⑶Water for moss emergence: Pour this water as soon as the garlic moss emerges.
⑷Swelling water: Pour this water after pulling out the garlic moss.
2. Mulching with plastic film Mulching with plastic film is the key to increasing garlic production. It can increase the ground temperature, decompose organic matter quickly, reduce water evaporation, and meet garlic's environmental needs. After pouring the coating water, if the ground still sinks slightly, use a laminating machine or manual method to cover it. No matter which method is used, the mulch film must be tightened and pressed firmly on both sides to prevent the mulch film from being lifted up when strong winds blow in autumn and winter.
3. When the garlic sprouts have just broken through the soil, pierce the mulch film in time to remove the seedlings. Generally, use the morning or evening when the temperature is low and the mulch film is less elastic. Use a new broom to gently pat the mulch film or use a bamboo rake. Carry out light columbine.
4. Artificial weeding During the growth period of garlic, the temperature is relatively low, and the weed damage is mainly after the Spring Festival. Because of the mulch covering, we rely on artificial weeding. The method is to use thick iron bars or 8mm steel bars to make a small "7"-shaped ditch, and break the mulch film into small holes to eradicate small grass seedlings.
5. Pulling the garlic moss When the upper part of the garlic moss curls up from the bottom, it is the best time to pull the garlic moss. The method is to lift it gently by hand from 11 noon to 3 pm every day.
3. Fertilization of green food The principle of fertilizing garlic is to use organic fertilizer as the main part, and a small amount of chemical fertilizer according to the formula; use base fertilizer as the main part, supplemented by top dressing.
1. As base fertilizer, in late September, apply 5,000kg of high-quality farmyard manure (fully decomposed manure, compost, and cake fertilizer), 20kg of urea, and 10kg of potassium sulfate per 667 square meters. It is required to spread evenly and then plow the land deeply. 2. In early April of the second year of top dressing, combined with watering to strengthen the seedlings, apply 10kg of quick-acting fertilizer urea per 667 square meters. In mid-April, spray 0.5kg potassium dihydrogen phosphate dissolved in 50k per 667 square meters.
