Onion garlic vegetables fertilization should be treated differently

Onion and garlic vegetables should be treated differently, such as green onions, onions, and leeks. Fertilizing technology is very important in their usual management processes and will have a certain impact on production. Onion garlic vegetables fertilization method is as follows:

Basal fertilizer: Planting green onions, garlic, onion and leeks all need to be applied with basal fertilizer, which is generally applied when combined with soil preparation and soil preparation. The perennial mussel composted soil is 1,000-1500 kg, superphosphate 8-10 kg, and potassium sulfate 5- 10 kg.

Weeping onions: Fertilizers began to be applied 7 days after planting. Fertilizers were topped with 20% of manure, and then gradually increased in concentration. Weighing onions was needed 5-8 times for all onions. Excrement 750 kg, with the application of urea 10-15 kg, potassium sulfate 10 kg. Fertilizers are required to be applied in the evening. After application, watering is required to flush the onion leaves to the soil in order to facilitate root absorption.

Onion: After the clearing, the top-hatching stems and leaves begin to grow vigorously, and the bulbs are expanded before the application. Normally, 10 kg of ammonium sulfate is applied per mu, and 75 kg of plant ash is applied. After the beginning of summer, when the bulb began to expand, the manure was applied once and the amount of 200 kg per mu was used. In addition, when the onion expands, another top dressing is applied, applying 15 kg of urea per mu and watering in time to keep the ground moist. Afterwards, the bulb matures gradually and it is necessary to stop fertilization and irrigation. Otherwise, the water content in the bulb will be too much to store.

Garlic: Topdressing differs depending on the purpose of cultivation and the condition of the seedlings. Receiving green garlic, the garlic leaves are required to be soft and tender, grow rapidly, and top dressings should be treated with human feces and urine, combined with thin water supply and watering. Harvesting garlic for a long time, should pay attention to regular fertilizer, green garlic period can promote the growth of garlic, bulb expansion should not be more fertilization, so as not to delay maturity.

Leek: After raising the seedlings to a height of 13 cm, topdressing is started, and 10% feces water is poured. After 20 days, the fertilizer is topdressed once, and 20% feces water is poured. After transplanting to survive, topdressing was started, topdressing was applied every 5-6 days, and the concentration was gradually increased from 10% of manure mixed to 50%. You can top-dress twice each time you harvest. No nitrogen fertilizer when bolting, fertilization after flowering to promote delivery.
