A kind of planting method of coltsfoot

Abstract

The invention discloses a Tussilago farfara planting method. The Tussilago farfara planting method includes the following steps: 1) land selection and soil preparation; 2) transplanting; 3) hidden area establishment; 4) field management including watering, soil loosening, leaf reducing, ventilation, topdressing, and soil covering; 5) disease and pest control; and 6) harvesting and processing. Compared with the prior art, the Tussilago farfara planting method has the advantages that the transplanting survival rate is increased by 10-15%, the incidence rate of diseases and pests is decreased by 1.8-3.5%, the yield of medicinal materials is increased remarkably, the yield of dried flower buds can reach 87.5-100 kg per mu, and is increased by about 25% in average.

Description

technical field [0001] The invention belongs to the technical field of planting Chinese medicinal materials, in particular to a method for planting coltsfoot flowers. Background technique [0002] Coltsfoot, also known as winter flower, is a perennial herb of the genus Coltsfoot in the family Asteraceae. Dried flower buds are used as medicine. It is warm in nature and pungent in taste. It belongs to the lung meridian. It has the functions of moistening lung and lowering qi, relieving cough and reducing phlegm. It is mainly used to treat acute and chronic bronchitis, tuberculosis, cough, asthma and other diseases. In the past, coltsfoot mainly relied on wild collection. With the increase in market demand, the purchase price in production areas has increased, and the amount of unrestricted artificial collection has increased, resulting in a sharp decline in the number of wild resources and the gradual expansion of artificial cultivation areas. It has become the current plantin...

Problems solved by technology

This method can effectively improve the survival rate of coltsfoot flowers, and compared with the traditional planting method, its yield can be increased by 15-20%. However, burning the cut vegetation on the spot during the site preparation will lead to a decrease in the phosphorus content of the land and affect the soil quality. On the other hand, vegetation is also a fertilizer resource. Incineration pollutes the atmosphere and causes waste of resources, which does not conform to the green environmental protection concept of modern agriculture.

At the same time, coltsfoot has strict requirements on temperature and soil pH value. This method does not create a suitable planting environment for coltsfoot, and still maintains the traditional management method. Although the emergence rate, seedling growth speed, and yield have improved, it is still difficult Meet market requirements
