Onion seedlings poured back to Qingshui in mid-March. In early April, when the height of the seedling is 15-30 cm, 1-2 seedlings are planted, and the seedling distance is 5-7 cm. The seedlings can be combined with loose soil and weeding. From late April to May, the temperature rose to 20°C and the height of the seedlings was 30-50 cm. It was a period of vigorous growth of onion seedlings and good management of fertilizer and water was needed. Can be staged to track the effect of fertilizers, such as urea, compound fertilizer, etc. 2-3 times, 15-20 kg per acre. From late May to early June, it is necessary to control and promote integration. More seedlings were watered, and the onion seedlings were strong. It was not until 4-5 days before transplanting that they were poured with water to facilitate seedling growth. In the May-June period, we must also do a good job in preventing and controlling pests such as green onions, leaf miners, and thrips. Onion is generally transplanted in mid-to-late June. Transplanting should select high-land, fertile land plots and avoid heavy crops. It is best to rotate crops with food crops. The distance between the onion and the ditch depends on the variety. The length of the onion sulcus with long white and high soil is more than 80 cm. Onion ditch is mostly saddle-shaped. The ditch is 20-30 meters long and the longest is not more than 50 meters. The ditch is north-south. ? Transplanting should use one or two strong seedlings. Changbai-type onions (such as Zhangqiu green onions) are generally 18,000-20,000 plants per acre. The planting is usually done with dry planting. After the ditching, the onion shoots are arranged one by one on the side of the ditch, and the soil is smashed down from the other side and finally watered.
