The leeks harvested by leeks are generally appropriate, usually harvesting 4-5 times a year, and harvesting 2-3 æ˜¥å£ before spring. In summer, the cultivation of leeks requires high yields, mainly in raising the roots, so that the plants produce more tillers, so they are generally not harvested and lay the foundation for the autumn harvest. Generally 2-3 收 can be harvested in the fall. If too many pods are harvested, it will cause premature plant failure and reduce the yield and quality of the leeks. In winter, harvesting is stopped 30-40 days before the wilting of leeks, and it naturally withers, so that the root stalks can accumulate more nutrients and create conditions for the plants to overwinter and grow in the coming year. When harvesting leeks, the height of sorghum should be appropriate, and the sorghum should not be too low. Generally, the stalks should be harvested at about 4 cm from the ground at the roots, and the cutting edge should be yellow. After each harvest, the knife edge should be raised slightly. Within 2 days after harvesting, fertilization and watering should not be applied, so as to avoid infection of bacteria in the air and diseases and insect pests, resulting in rot.
