Perilla price: it is understood that dried wild perilla costs 45 yuan per jin, and fresh perilla costs 10 yuan per jin.

How to grow it: perilla is highly adaptable and not demanding about soil; it grows well in well-drained sandy loam, loam and clay loam, around houses and behind them, beside ditches and field edges, and in fertile soil. The previous crop is best a vegetable. It can be planted under young fruit trees. Sow in spring; the sowing time differs by one month between south and north, March in the south and mid-to-late April in the north. For direct sowing, drill in rows in the bed, opening furrows 2-3 cm deep at a row spacing of 60 cm, scatter the seeds evenly into the furrows, and cover with a thin layer of soil after sowing. Hill sowing: row spacing 45 cm, plant spacing 25-30 cm, sow in hills and cover with shallow soil. Water immediately after sowing to keep it moist; the sowing rate is 15-18.75 kg per hectare. Direct sowing saves labor, grows fast, allows early harvest and gives high yield.

Perilla has a relatively short growing period; two and a half months after transplanting, the whole plant can be harvested, and since the whole plant is used as medicine, nitrogen fertilizer is the main type used. Apply fertilizer in a concentrated way before the rows close. For direct-sown and seedling-raised plots, topdress when the seedlings are 30 cm tall, loosen the soil and earth up to bury the fertilizer well. Apply fertilizer once more before the rows close, in the same way as above. When harvesting perilla, choose a sunny day to cut it, as the aroma is strong and it dries easily; for perilla leaves used as medicine, harvest in late July to early August, before perilla flowers. While collecting seeds, pay attention to selecting and keeping good seeds. Choose robust plants with high yield, wait until the seeds are fully mature before harvesting, dry them in the sun and thresh them for use as seed.
