How to grow Pinellia ternata? Detailed cultivation techniques for Pinellia ternata (Part 1)
(1) Site selection and land preparation: Choose loose, fertile, neutral sandy loam soil with strong water and fertilizer retention capacity; it can also be intercropped under orchards or tall crops such as corn. Plow the soil in winter to let it weather and mature. In early spring, level the land, apply 30000 kg of barnyard manure or compost and 750 kg of superphosphate per hectare, then rake fine and level to make high beds 1.3 m wide with furrow width of 40 cm. (2) Propagation: Generally, tuber or bulb propagation is the main method; seed propagation is also possible, but the seed germination rate is low and the production cycle is long

How to prevent and control common diseases in the middle and late stages of Pinellia ternata growth
Tuber rot disease 1. Causes and symptoms: Occurs during high temperatures, the rainy season, prolonged excessive soil moisture, and the swelling period of tubers and bulbils. In the early stage of the pathogen infecting Pinellia ternata tubers, irregular black spots appear around the edges of the tubers, and these spots rapidly spread outward. After 3-4 days, numerous pathogen spots merge together and continue to infect the interior of the tuber. At this point, the root system of Pinellia ternata begins to shrink, and the above-ground leaves gradually turn from green to yellow and wither.

Pinellia ternata cultivation techniques (part two): detailed planting methods
(1) Propagation methods Pinellia ternata is mainly propagated by tubers and bulbils, and can also be propagated by seeds. ① Tuber propagation After Pinellia ternata has been cultivated for 2 years, the underground tubers can be dug up after the stems fall over in June, August and October each year. Select small tubers about 0.5 cm in transverse diameter that are robust and free from pests and diseases as seed. Mix the seed tubers with semi-dry, semi-moist fine sandy soil, store them in a ventilated and cool place, and take them out for planting in the winter of the same year or the spring of the next year. Planting in the spring of the next year is preferable. With a row spacing of 15 cm, open furrows 10 cm wide and about 5 cm deep, and arrange two staggered rows in each
