Description

Method for cultivating florists chrysanthemum grafted folium artemisiae argyi
Technical Field
The invention relates to the technical field of flower cultivation, in particular to a method for cultivating tribute chrysanthemum grafted folium artemisiae argyi.
Background
Florists Chrysanthemum is the dry capitate of cultivated varieties of Chrysanthemum of the Compositae family, and is named as Chrysanthemum morifolium (Ramat) Tzvel, Gongju' which is recorded in Ben Cao gang mu as nine hundred varieties of Chrysanthemum. Florists chrysanthemum is recorded in Chinese pharmacopoeia (2020 edition) and Chinese herbal piece processing standard in Anhui province (2019 edition). Florists chrysanthemum is also called Huangshan florists chrysanthemum and Huizhou florists chrysanthemum, also called Huizhou chrysanthemum. The chrysanthemum of four names of China is called together with Hangzhou chrysanthemum, Chuzhou chrysanthemum and Bo chrysanthemum. Because it is used as a tribute in ancient times and is contributed to emperors, it is named "tribute chrysanthemum".
Huangshan tribute chrysanthemum is originally called ' Huizhou tribute chrysanthemum ', also called huizhou chrysanthemum ', and is a good variety bred from chrysanthemum population. Mainly produced between the famous tourist resort Huangshan scenic spot and the cool peak of the national-level natural reserve. The chrysanthemum is originally produced in Jinzhuling Ling of she county, is only produced in Jinzhuling Ling of Anhui she county, grows in mountainous regions with relatively high altitude, mountains and mountains of Huangshan tribute chrysanthemum production areas fluctuate, green water flows for a long time, summer does not have summer heat, winter does not have severe cold, four seasons are clear, the chrysanthemum is warm and humid, the rain quantity is abundant, the sunlight is sufficient, the annual average temperature is 16.4 ℃, and the chrysanthemum belongs to tropical northern marginal areas and is particularly suitable for the growth of tribute chrysanthemum. Due to the unique climatic conditions and the excellent ecological environment of the mountain, the florists chrysanthemum is different from the florists chrysanthemum growing on the plain in appearance form and quality, and has both ornamental value and medicinal function. The production of Huangshan tribute chrysanthemum is very exquisite, after the fresh chrysanthemum is picked, the chrysanthemum is dried in the shade by bamboo \31775, and then the chrysanthemum is baked by charcoal fire with great intensity, and the finished tribute chrysanthemum is better in large and white flower. Florists chrysanthemum is always regarded as an important Chinese medicinal material and exported to southeast Asia.
Huangshan tribute chrysanthemum has the functions of dispelling wind and clearing heat, nourishing liver and improving eyesight, and cooling and detoxicating, and can be used for treating common cold, furuncle and pyogenic infections, high blood pressure, arteriosclerosis and other diseases. As a traditional Chinese medicine and a health care product, the health care and medical value of florists chrysanthemum is generally accepted by consumers, and the florists chrysanthemum has great market potential. As the quality requirement of Chinese pharmacopoeia (2020 edition) on Chinese medicinal materials is integrally improved, pesticide residue is a hard quality index of plant Chinese medicinal materials, and the current florists chrysanthemum planting also faces the problem of pesticide residue and the acute problems of disease resistance, insect damage resistance and the like of florists chrysanthemum.

In the comparative example, 50 plants are grafted, survival conditions are observed 15 days after grafting, and the survival rate reaches 48 percent after 24 plants survive.
Grafting and cultivating a plurality of florists chrysanthemum of different varieties by adopting the method of the embodiment 1, and transplanting the florists chrysanthemum to a field for planting when the grafted florists chrysanthemum grows to 12-15 centimeters; the chrysanthemum seedlings transferred into the field are subjected to fertilization management by adopting the special fertilizer for the florists chrysanthemum, and the fertilization times and the application amount are reduced according to the growth condition of the chrysanthemum seedlings. In addition, during the period, attention needs to be paid to preventing dryness and waterlogging, loosening the soil and weeding in time, replenishing fertilizer in due time and protecting the fertilizer requirement in the growth process of the florists chrysanthemum. When the florescence of the tribute chrysanthemum, the centralized collection is carried out.
The content of the florists chrysanthemum and the florists chrysanthemum grafted sample is measured and tested, and the result is shown in table 1. Wherein the serial number 1 is the test standard for measuring the content of chrysanthemum in the Chinese pharmacopoeia (2020 edition), and the serial number 2 is the test standard for measuring the content of florists chrysanthemum in the Anhui cannon standard (2019 edition). The serial number 3 is the slow tribute chrysanthemum, the serial number 4 is the golden tribute chrysanthemum, the serial number 5 is the mugwort leaf grafted golden tribute chrysanthemum, and the serial number 6 is the mugwort leaf grafted slow tribute chrysanthemum.
