1. Habit perennial herb, plant height 15-30 cm. Tubers globose or oblate, spicate inflorescences. Male flowers on top, female flowers on bottom, monoecious, flowering from May to July, fruiting from June to September. Pinellia ternata likes moisture, afraid of drought, afraid of strong light, in direct sunlight or water shortage conditions, easy to occur fallen seedlings. Shade-tolerant, cold-resistant, tubers can naturally winter, soil requirements wet, fertile, deep, with water content of 40%-50%, PH 6-8 was neutral reaction of sandy loam is appropriate, too sticky, sand and easy to accumulate water plot is not suitable for planting. Pinellia ternata seedlings appear three times a year, the first time in early April and early June, the second time in June to mid-August, the third time in August to October, each time after emergence growth period of 50-60 days.
2. Planting to use tubers and plant bud propagation mainly, but also seed propagation, generally planted in autumn and winter, can also be planted in mid-February.
3. Harvesting and processing tuber reproduction in the same year or the second year harvest, generally in summer and autumn after the stem withered seedlings dug. But it is better to harvest between summer mango seed and summer solstice. The average yield of fresh tubers per mu is 500-750 kg. The drying rate is 30%.

Planting techniques of Pinellia ternata
Land preparation is cold-resistant to drought and Pinellia ternata, and loose and fertile sandy or semi-sandy soil is the best, as well as general soil. Before ploughing, 100-150 kg of phosphorus and potassium fertilizer is applied per mu, and fine rakes are ploughed deeply to make east-west border. The sowing method is propagated with tubers, ditching with a gully according to the row spacing of 21-24 cm, with a depth of 4-6 cm, sowing into the seed ball according to the plant spacing of 5-7 cm, then cover the soil flat and push it twice with a big hoe. If the land is moist, do not water, wait for the seedlings to grow, look at the soil moisture appropriate watering. Field management of border rooms

About 120 kg of dry products can be harvested by interplanting Pinellia ternata in fruit forest per mu, and its planting benefit is 3-5 times higher than that of conventional crops. 1. Sow seeds.
