In winter, the weather is cold, there is little rainfall, there is plenty of sunshine, and sunshine hours are long. Attention should be paid to the sowing, breeding and planting management of Chinese medicinal materials. The fall and winter season is a good time for the overwintering management of some Chinese herbal medicines, and it is also the season most likely to be neglected by the farmers and peasants. In order to make full use of winter time to do some field management of Chinese herbal medicines, lay a good foundation for the next year's vigorous growth and increase production. The main points for the cultivation and management of Chinese herbal medicines in winter are suggested for your reference.
First, apply base fertilizer. Perennial Chinese herbal medicines should be applied to base fertilizers in autumn and winter, mainly organic fertilizers, and the application of phosphorus and potassium fertilizers will be beneficial to the growth of Chinese herbal medicines in the next year.
Second, clean garden disinfection. In the autumn and winter, the garden must be cleared in time to remove the diseased plants and leaves, concentrate and burn deeply, reduce the base number of overwintering pests and diseases, and disinfect lime in pests and diseases to eliminate overwintering pests and diseases.
Third, the plastic trim. Pruning is an important measure in the cultivation and management of Chinese herbal medicines and flowers. It is necessary to remove the branches and branches of the pests, thin and weak branches, and trim the branches to cultivate high-yield trees.
Fourth, prevent freezing injury. Fill the soil with water once before freezing to prevent freezing. It can be covered with straw and its thickness is about 5cm. After the Chinese herbal medicines suffer from frost, they should take prompt remedial measures, such as assisting the seedlings, making up the seedlings, reseeding the seeds, replanting seeds, etc., and strengthening field management.
