Fertilization technology is very important for the production of scallions, onion, garlic, leeks and other vegetables, and it also has a certain impact on its production. Basically the same is that the cultivation of this kind of vegetables need to apply enough base fertilizer, generally combined with soil preparation for the application, per acre applied to compost soil mixed fertilizer 1000-1500 kilograms, superphosphate 8-10 kilograms, potassium sulfate 5-10 kilograms . The difference is that green onions, onions, garlic, leeks have different requirements for top dressing.

Onion

The top dressing was started 7 days after the planting, and then 20% human fecal urine was used for top dressing. After the concentration was gradually increased, green onions needed to be top dressing for 5-8 times. The amount of fertilizer applied was light blue and the most prosperous period was growing. This period can use human urine per mu. 750 kg, with the application of urea 10-15 kg, potassium sulfate 10 kg. Fertilizers are required to be applied in the evening. Water should be applied after the application, and the feces on the onion leaves should be flushed into the soil so as to facilitate the roots to absorb the fertilizer.

Round onions

After the Qingming, the stems and leaves began to grow vigorously, and the bulbs were topped before expanding. Generally, 10 kg of ammonium sulfate was applied per mu, and 75 kg of plant ash was 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

Top dressing varies 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.

Amaranth

Seedling height 13 centimeters after the beginning of top dressing, with 10% of manure water pouring, interval 20 days after top dressing once, with 20% manure pouring. 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 fertilization when convulsions, fertilization after flowering to promote delivery.
