Its sowing method is extremely simple. After closing the ridges of corn and other plants, dig shallow trenches between the rows, spread the seeds evenly between the rows, then cover the soil slightly and water to keep the soil moist, and the seedlings can emerge about a month later.

Before freezing in winter, it is necessary to pour frozen water and apply overwintering fertilizer. It is recommended to cover the roots with farm manure. After thawing in spring next year, farm manure should be broken and leveled. When it comes to the season of Grain Rain during the Qingming Festival, 15 kilograms of urea per mu is applied to make its new leaves germinate, and fertilization should be watered immediately, which can not only reduce the concentration, so as not to cause the phenomenon of burning seedlings, but also quickly absorb fertilizer, and stop watering after entering summer to avoid stem and leaf rot.
