Weeding should be done frequently before closing the ridge for plant growth, and attention should be paid to weeding between seedlings in direct seeding area. When the seedling height in the drill field is 15cm, it should be fixed at 30cm, and the surplus seedlings should be used for transplanting. The plants in the direct seeding area grow fast and the density is high, so the plants grow in vain, and few plants are branched or not. Although it can reach the height of the plant, there are fewer leaves under the plant, poor illumination and air falling off, which affects the yield of leaves and perilla oil. At the same time, the stems with many leaves and few leaves also affect the specifications of the whole grass, so it is not too early to sow seedlings. From field planting to ridge sealing, loosen the soil and weed twice.

The growth time of perilla frutescens is relatively short, and the whole grass can be harvested two and a half months after planting, and the whole grass is used as medicine, so nitrogen fertilizer is mainly used. Concentrate fertilization before ridge closure.

After sowing or transplanting, if it doesn't rain for several days, water it in time. Pay attention to drainage in rainy season, dredge the operation channel, and prevent stagnant water from littering.
