Winter is the idle season, and it is the right time to plant scallions in the greenhouse

Using a fixed greenhouse to grow a crop of scallions during the winter idle season can improve the greenhouse's utilization rate and economic benefits, and also allows crop rotation, which not only creates a good preceding crop for the next crop but also does not affect the planting of early spring fruits and vegetables.

Planting method: when the late autumn vegetable production in the greenhouse has ended, along with careful land preparation, apply 3000-4000 kg of high-quality organic fertilizer per mu, then open furrows and plant the scallions. Row spacing 25-30 cm, plant spacing no more than 1 cm, planting depth about 3 cm. The scallions to be planted can be selected from smaller plants among the autumn scallions.

Post-planting management: after planting, irrigate thoroughly once in time, and irrigate thoroughly once more before the soil freezes. After the soil freezes, be sure to clear away the dry scallion leaves on the ground. After snow, promptly sweep away the snow on the greenhouse film to improve light and increase the greenhouse temperature. From late February to early March, when the scallions begin to turn green, irrigate thoroughly once in time, and farmers with the conditions had best apply 10-15 kg of ammonium sulfate per mu with the water. After that, irrigate frequently with small amounts of water, and irrigate once more 1-2 days before harvest. In this way, it is both convenient to lift the scallions and able to keep the scallions fresh and tender. After harvest, promptly prepare the land and sun-dry the field, ready for transplanting early spring fruit and vegetable seedlings.
