Last Updated: 2024/11/22, 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 the production experience, the drug farmers should do the following four points during the overwintering period of Pinellia ternata: under normal circumstances, the tuber of Pinellia ternata begins to take root and emerge about half a month after it is planted, and sometimes rotten seeds will occur because of low air temperature. so the growth of the seed stem should be checked in time. The soil can be gently removed by hand, bamboo slices, sticks, etc., where the seedlings have not emerged for a long time, usually without roots or roots.

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.
