Before sowing, combined with shallow ploughing of 0.5 to 2 kg per 667 square meters of Phosphorus-containing Phosphorus powder, to prevent and control underground pests such as black cashew beetle and earthworm. Sixth, timely harvest until the yellow skin becomes soft, timely harvest, to prevent the lower part of the grain growth and mold. After the whole plant is harvested, it cannot be piled up to prevent heat from deteriorating. Drying after 5-7 days. The seeds continue to dry for a few days and are sold for sale.
