The purpose of summer and autumn green onion cultivation is to supply the market demand from August to October. The Yangtze River basin is generally planted in February and planted in the field in June. There are two kinds of ditching planting and sorghum planting when planting. When the planting is earlier and the market is late, it can be ditched for cultivation. The row spacing of the ditching planting is 40-50 cm, the plant spacing is 3~4 cm, and about 40,000 plants per acre are planted. Planting is late, but it does not need to be cultivated in the summer. It can be planted with sorghum, 3 to 4 holes per hole, and the hole distance is 20 cm. It is necessary to weed and eliminate insects in time during summer growth. The soil drought should be watered in time, and the water in the rainy season should be drained in time. After the seedlings are slowed down, the fertilizer can be applied once a day, and the soil is 1-2 times. Summer and autumn green onions can be harvested at any time, mainly for eating fake stems.
