* The advantages of hard-core green onions. Hard-core Welsh onion is drought-resistant, heat-resistant and storage-resistant, and its seed consumption is small. Planting an acre of green onions only needs about 2 kilograms of seeds, and the yield per acre can reach about 3500 kilograms. In the case of proper management, green onions generally do not die, and there is basically no need to control pests and diseases. Moreover, the amount of labor per mu of green onions is small, and one or two people in the family can manage more than ten acres of green onions.
* Shortcomings of hard-core green onions. Onion planting should not be continuous cropping, nor should it be mixed with ginger, leek and other crops. Because they are similar crops, they will affect each other when growing, so it is best to rotate with other vegetables. In addition, the growth of Welsh onion at seedling stage is weak, and the plants are small, so the nursery place should be far away from the cool and windproof area. At the same time, green onions are prone to lodging in the growth process, which needs attention.
