Yuxian onion and garlic vegetables mainly include onion, onion, leeks, etc., planting about 10,000 mu per year, fertilization techniques are as follows:

1, base fertilizer planting green onions, garlic, onion and leek all need to apply enough base fertilizer, generally combined with soil preparation for the application, per acre applied to compost soil mixed fertilizer 1000-1500 kg, superphosphate 8-10 kg, potassium sulfate 5 -10 kg.

2. Onion cultivars began to administrate fertilizer 7 days after planting, and then used 20% human urine to top-dress, after which the concentration gradually increased. Onions needed to be topdressed for 5-8 times, and the amount of fertilizer applied was intensive and vigorous. 750 kilograms of human waste, with 10-15 kg of urea and 10 kg of potassium sulfate. 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.

Round green on top of fertilizer after the Qingming stems and leaves began to grow vigorously, before the expansion of the bulb, generally applied per acre of ammonium sulfate 10 kg, 75 kg of planting ash. 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 dressing 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.

The height of seedlings during the seedling raising period is 13 centimeters and the top dressing is started. The topsoil is poured with 10% of manure, and the fertilizer is topdressed once every 20 days, and poured with 20% manure. After transplanting to survive, topdressing began, topdressing was applied every 5-6 days, and the concentration was gradually increased from 10% of manure mixed with 50% of manure, and the top dressing was used twice for each harvest. No nitrogen fertilizer when bolting, fertilization after flowering to promote delivery.
