Good varieties are the first condition to increase yield. Once we planted, we also needed to set up a seed field. The planting method is the same as that of ordinary plants. During the period, we strengthen field management and properly apply phosphate and potassium fertilizers before flowering. The seeds have full grains, and at the same time more good seeds can be obtained. When the seeds are seven or eight mature, they can be harvested. The harvested seeds can be placed in a ventilated and dry shady place for 4-6, and they can be threshed to remove impurities and deflated seeds.
