The average yield per mu of scallion is several kilograms, with the planting method attached.

The yield per mu of scallion is related to the variety of scallion, weather, planting management technology and other factors. If the planting management is proper, the yield per mu can generally reach about 6000-8000 kg, and the high yield can reach more than 10000 kg. To grow green onions, in order to achieve high yield, it is necessary to choose varieties that are bolting-resistant, cold-resistant, disease-resistant and suitable for local climate. Spring planting and autumn harvest of green onions can generally be selected, such as Weiming No.3, No.4, Minghui and Xinzhuangyuan. Spring planting and winter harvesting green onions can generally choose Yudou green onions, Xingxing No.2, Mingmen and Changfeng green onions; If you plant green onions in summer and autumn, you can choose varieties such as general taste and long summer, spring festival evening smoke and famous evening smoke.

1. How many kilograms of green onions are produced per mu?

1. With proper planting management, the yield per mu of Chinese onion can generally reach about 6000-8000 kg, and the high yield can reach more than 10000 kg. The specific yield is related to the variety of Chinese onion, weather and planting management techniques. In order to achieve high yield of scallion, it is necessary to select improved varieties, carry out scientific water and fertilizer management and pest control.

2, spring planting and autumn harvesting green onions, if you want high yield, you can generally choose Weiming No.3, No.4, Minghui and COVID-19; Planting green onions and harvesting winter onions, if you want high yield, you can generally choose Yudou onion, Star No.2, Mingmen, Changfeng onion, Fengyuyi and other varieties; When planting green onions in summer and autumn, you can choose varieties such as general taste, long summer, spring festival evening smoke and famous evening smoke. When selecting varieties of special plots (continuous cropping plots in rainstorm), we should choose varieties that can tolerate continuous cropping, such as Puweixing, Yudou Welsh Onion, Zhixing No.3, Zhixing No.4 and so on.

Second, the planting method of green onions

1, seed selection and seed soaking

Choose varieties that are bolting-resistant, cold-resistant, disease-resistant and suitable for local climate. In order to improve the germination rate of seeds, seeds can be soaked in clean water 1 day before sowing, and some water can be dried before sowing.

2. Land preparation and selection

Green onions should be planted in sandy soil with loose and fertile soil, flat terrain, sufficient sunshine and good irrigation and drainage conditions, and crops such as green onions and garlic have not been planted for more than three years. First of all, soil preparation and fertilization should be carried out. Soil preparation can be at least 30 cm deep. Weeds and pests should be removed. Clods should be broken, raked and fertilized with decomposed fertilizer. Then ditch, the ditch width is about 1- 1.5 m, and the ditch spacing is generally 80- 100 cm.

3. Scientific planting

There are three main planting methods of green onions, namely sowing, dividing plants and planting balls. Sowing and planting can adopt the method of hole sowing, dig small holes in the soil, keep a good spacing, and sow the seeds into the holes. Planting by plant can divide the green onion into several small pieces and then plant it. Bulb planting can choose high-quality bulbs suitable for local climate, without pests and diseases, tidy up the soil and plant bulbs.

4. Tian Tuan management

After the survival of green onion planting, attention should be paid to weeding among seedlings, regular irrigation and drainage, topdressing according to the growth situation, and prevention and control of pests and diseases. When the rainfall is heavy, it is necessary to prepare for flood control and drainage, and at the same time, intertillage in time after the rain to avoid land hardening. The prevention of diseases should focus on prevention, and adhere to the principle of agricultural prevention, physical prevention and biological prevention, supplemented by chemical prevention.

5, timely harvesting

When the leaves and pseudostems of scallion can be eaten at the same time, and the growth of tubular leaves of scallion reaches the peak, it is generally the highest yield period of scallion and the suitable harvest period of scallion. When harvesting scallion, one side of the scallion ridge can be dug down with a fork or shovel until the root of the scallion is exposed, and then the scallion is gently pulled out by hand, and then the soil is shaken off, spread flat on the ground and dried properly, or harvested mechanically.
