Skillful management of winter drought and half summer
After planting in dry Pinellia ternata and early winter, Chinese medicinal materials enter the winter tube stage, if the overwintering management is not good, it will directly affect its yield and quality. Therefore, it is very important to strengthen its winter management. According to production experience, drug farmers should achieve the following four points during the drought and overwintering period:
Check the seed stem usually, the tuber of Pinellia ternata begins to take root about half a month after planting, and sometimes the rotten seed will occur because of the low temperature, so the growth of the seed stem should be checked in time. For places that have not emerged for a long time, the soil can be gently removed by hand or bamboo slices or sticks. If there is no root or the stem with yellow and black roots is inferior, it should be dug up and replanted in time.
If there is continuous rain in winter, the soil is easy to be waterlogged and anoxic, which is not only not conducive to the root of Pinellia tuber in the ground, but also lead to disease and rot. Therefore, at this time, we should pay attention to ditch drainage, so that the rain stops the water to dry. If drought occurs in winter, it will cause tubers to dry up and shrink. To affect the underground growth, furrow irrigation can be adopted to let the water permeate and moist the soil through the ditch, and the water in the ditch can be discharged in time after irrigation.
Weed removal after planting in Pinellia ternata for a month, ploughing and loosening the soil should be carried out on a sunny day, perennial weeds should be removed in time, and weeding should be mainly planing or pulling weeds to prevent damage to tubers. For plots with serious weeds, you can choose sunny days, spray 60 kg of water with 10% glyphosate 800 kg 1000 g per mu; or spray 50 kg of water evenly with 20 g water-free agent 150 kg 250 ml per mu.
The application of farm manure to the planting land can not only increase the fertilizer efficiency and promote the growth of tubers, but also keep heat and moisture. Therefore, during the severe cold, 2500 to 3000 kg of rotten pig and cattle dung per mu, 50 kg of rotten cooked cake fertilizer or 75 kg of plant ash should be used evenly between the rows of the border to overwinter.

On weeding of Pinellia ternata
Pinellia ternata is a dicotyledonous plant. In the cultivation process of this kind of medicinal materials, the problem of weeding is relatively thorny, and there is no clear and effective method at present, mainly artificial weeding, and no herbicide has been used for weeding experiment. It is said that an expert specializing in Pinellia ternata used butylamine to weed after sowing in dry and Pinellia ternata, but we do not know the specific concentration. You might as well use butachlor to start with a low concentration (100 times liquid) and test in a small range with a gradient ratio. After observation, it is determined that the herbicide has obvious killing effect on other weeds.

The method of planting Pinellia ternata in greenhouse
Pinellia ternata, also known as Pinellia ternata, Sanbaotiao, Ma Yuguo, is a commonly used Chinese herbal medicine, which is distributed in the north and south of our country. In recent years, due to the reclamation and utilization of barren mountains and the extensive use of herbicides in farmland, the ecological environment has been destroyed, the resources have decreased year by year, and the price has been rising. According to the survey, at present, Pinellia ternata commodities are scarce in 17 professional markets across the country, and the supply exceeds demand, and the market price is firm at 36-42 yuan / kg. Therefore, the market prospect of artificial planting Pinellia ternata is very broad. In recent years, we
