Four key points to grasp in winter management of Pinellia ternata
1. Check the seed tubers: Normally, the tubers of Pinellia ternata begin to take root and sprout about half a month after planting. Sometimes, due to low temperatures, tuber rot may occur, so the growth of the seed tubers should be checked in a timely manner. For spots where sprouts have still not emerged, the soil can be gently scraped open by hand or with a bamboo strip, wooden stick, etc. Any seed tubers that have not rooted or whose rootlets are yellow-black are inferior and should be dug out and replanted in a timely manner. 2. Prevent waterlogging and drought: If continuous overcast and rainy weather occurs in winter, the soil is prone to waterlogging and oxygen deficiency, which is not only unfavorable for the tubers of Pinellia ternata to take root underground, but also causes disease and rot.

How to carry out field management of licorice? Four key points to master
Cultivation: Licorice seedlings grow slowly, and weeds have a relatively large impact on them. Cultivation should be combined with timely removal of weeds, with weeding 2-3 times in the same year. After the plants grow larger, weeds become fewer. Pay attention to pulling out weeds, and avoid hoeing the soil, so as not to damage new shoots sprouting from the rhizome. Topdressing: Licorice belongs to the legume family, and its root nodules have nitrogen-fixing ability, so nitrogen fertilizer is generally not applied, and phosphate fertilizer is mainly used for topdressing. After the aboveground parts of licorice wither in late autumn, 2000 kg of decomposed farmyard manure can be applied per mu to cover the ground, so as to increase ground temperature and soil fertility. Thinning: For direct-seeded seedlings of the same year, when they have 2-3 true
