Last Updated: 2024/11/22, Planting a crop of green onions in a fixed greenhouse in winter leisure season can not only improve the utilization rate and economic benefit of the greenhouse, but also rotate stubble, which not only creates a good stubble for the next crop, but also does not affect the planting of fruits and vegetables in early spring. Planting method: when the late autumn vegetable production in the greenhouse is over, combined with meticulous soil preparation, apply 3000 kg of high-quality organic fertilizer per mu, and then open ditches to plant onions. The row spacing is 25ml 30cm, the plant spacing is not more than 1cm, and the planting depth is about 3cm. The planted onions can choose the smaller plants from the autumn scallions.

Management after planting: irrigate once in time after planting, and irrigate the soil again before freezing. Be sure to remove dried onion leaves from the ground when the soil is frozen. After snow, it is necessary to sweep away the snow on the greenhouse film in time, increase the light and increase the temperature of the greenhouse. From late February to early March, when spring onions begin to turn green, they should be irrigated once in time, and farmers with conditions had better apply 15kg ammonium sulfate per mu of water. After that, small water should be irrigated frequently, and two days before harvest, water should be irrigated again. In this way, it is not only easy to pick up onions, but also keep green onions fresh and tender. After harvest, we should prepare the field in time and prepare to plant early spring fruit and vegetable seedlings.
