How is the output of Pinellia ternata?
Pinellia ternata is usually propagated by tubers, which can be harvested three times a year, that is, the first harvest in April and around June 20; the second time on August 10-20 and the third time on September 10-15, that is, three times when plant buds mature and cultivate soil three times or take plant buds to plant separately, it is also a stage of growth, development and maturity of underground bulbs. However, the domestic species are usually harvested once after autumn, because Pinellia ternata continues to grow and expand the underground corms.
In field management, plastic film can not only keep soil moisture, but also increase the soil temperature by about 4 ℃, so that Pinellia ternata enters the growing period 20 days ahead of time and the yield is high. Remove the plastic film when the seedlings emerge. Corn can be intercropped or corn can be intercropped in the ditch. A layer of wheat bran can be sprinkled between the rows in summer. It can not only reduce the ground temperature of 4 ℃ 5%, but also increase the soil water content of 3%, and increase the yield by 20% 50%. In the hot summer, when there is much rain in the later stage, the wheat bran should be removed in time according to the wet condition of the ground to prevent the mother from rotten.

What to do when dentate mushrooms appear?
The fruiting body of young mushroom develops normally, but the edge of the cap is like a serrated, convex and concave uneven. The cause of this disease is mainly caused by strong wind stimulation. The wind is strong, the humidity is less, the young Pleurotus ostreatus fruiting body is affected by these adverse environments, resulting in metabolic interference, some tissue cells on the edge of the cap are damaged, resulting in serrated Pleurotus ostreatus. Prevention and control methods: windy weather, do not open tuyere or less tuyere, if urgent ventilation, the north wind only opens the south tuyere, the south wind only opens the north tuyere. At the same time, the amount of spraying water was increased to improve the humidity of the mushroom shed.

Pinellia ternata, a traditional Chinese medicine, can be planted three times a year. Sowing in April, harvesting in July; sowing in July, harvesting in October; sowing in October, harvesting in April of the following year. Three crops of Pinellia ternata can earn more than 5000 yuan per mu. Selection of soil preparation: planting pinellia ternata in loose fertile soil is good. Combined with soil preparation, 3000~5000 kg of miscellaneous fertilizer, 25~30 kg of calcium superphosphate and 1000 kg of plant ash should be applied per mu, and ammonium bicarbonate should not be applied. After deep ploughing and fine harrowing, the ridge is 1.3 meters wide, 17 cm high and 30 cm wide. intercropping in furrow
