Fertilization of onion and garlic vegetables should be treated differently, such as green onions, onions, and leeks. In their usual management process, fertilization technology is very important and will have a certain impact on production. The fertilization methods of onion and garlic vegetables are as follows: Base fertilizer: planting green onions, garlic, onions and leeks must be applied to the base fertilizer, generally combined with the preparation of the soil for sputum application, 1000-1500 kg per mu of mulch mixed soil, 8-10 kg of superphosphate, potassium sulfate 5- 10 kg. Green onion: start topdressing 7 days after planting, first use 20% human excrement and topdressing. Afterwards, the concentration will gradually increase. The green onion needs 5-8 times of topdressing. The amount of fertilization is the highest in the growth period of white onion. The urethral urine is 750 kg, with 10-15 kg of urea and 10 kg of potassium sulfate. Fertilization is required to be applied in the evening. After application, watering is required, and the manure water on the onion leaves is washed into the soil to facilitate the absorption of fat in the roots. Onion: After the Qingming, the stems and leaves began to grow vigorously and the bulbs were inflated before application. Generally, 10 kg of ammonium sulfate per acre was applied, and 75 kg of grass ash was applied. After the summer, when the bulb begins to expand, the manure is applied once and the amount is 200 kg per mu. In addition, the onion is inflated, and then a top dressing is applied. 15 kg of urea per acre is applied and watered in time to keep the ground moist. Later, the bulbs gradually mature, and the fertilization and irrigation should be stopped. Otherwise, the water content in the bulbs is too much and it is not resistant to storage. Garlic: Topdressing varies depending on the purpose of cultivation and the condition of the seedlings. The main reason for collecting green garlic is that the garlic leaves are soft and tender, and the growth is rapid. The top dressing should be applied to the manure and manure, and the thin application should be combined with watering. The cultivation time of harvesting garlic is longer, and attention should be paid to regular topdressing. Fertilization during green garlic can promote the growth of green garlic. It is not advisable to apply more fertilizer during the period of bulb expansion to avoid delaying maturity. Amaranth: After the seedling height is 13 cm, the topdressing is started, and 10% of the manure is applied. After 20 days, the fertilizer is applied once again, and 20% of the manure is applied. After transplanting, the topdressing is started, and it is applied once every 5-6 days. The concentration is gradually increased from 10% of manure to 50%. It can be topdressed twice for each harvest. Do not fertilize when bolting, fertilize after flowering to promote tillering.
