Description

Technical Field

[0001] The invention belongs to the technical field of artificial planting of snow lotus, and particularly relates to a coating agent for improving the emergence rate and survival rate of snow lotus seeds, a coating agent preparation method, and a coating seed preparation method. Background Art

[0002] Snow lotus is a perennial herb of the genus Saussurea, 15–35 cm high. The rhizome is thick, with many brown leaves surrounding the neck. The stem is thick, 2–3 cm in diameter at the base, and glabrous. The leaves are dense, basal leaves and stem leaves are sessile, and the leaves are elliptical or ovate-elliptical, up to 14 cm long and 2–3.5 cm wide, with obtuse or acute apex, decurrent base, sharp teeth on the margin, and glabrous on both sides; the uppermost leaves are bract-like, membranous, light yellow, broadly ovate, 5.5–7 cm long and 2–7 cm wide, surrounding the inflorescence, with sharp teeth on the margin.

[0003] Snow lotus contains protein, amino acids, flavonoids, alkaloids, etc. It has the effects of promoting blood circulation, dispelling cold and dampness, stopping bleeding and reducing swelling, and expelling toxins from the body.

[0004] The vitamin C contained in snow lotus can soften blood vessels, prevent aging, remove wrinkles and lipid accumulation, and improve microcirculation. It can make the skin shiny and prevent the carcinogenic process of chemical substances, so as to achieve the purpose of cancer prevention, anti-cancer, and cancer treatment, and prolong life. Snow lotus can be used as a facial cream to accelerate skin metabolism, reduce wrinkles, keep the skin shiny and plump, and delay aging. It also has a good effect on facial freckles and liver spots.

[0005] Snow lotus seeds germinate at 0℃, grow at 3-5℃, and seedlings can withstand severe cold of -21℃. Due to its short growth period, it can quickly germinate, grow, bloom and bear fruit in a relatively short period of time, which is also the result of its long-term adaptation to the environment. Although it takes 5 years to bloom, the actual growth days are only 8 months.

[0006] In 1996, China listed Tianshan Saussurea as a second-class protected plant. Tianshan Saussurea is the only Saussurea plant listed in the "Chinese Plant Red Book" and is a second-class endangered species in China. In 2000, the State Council's Document No. 13 explicitly prohibited the collection of wild Saussurea. The medicinal effects of Saussurea have been recognized. At present, there are more than 100 companies in China that have developed Saussurea medicines, which are no longer in the raw material state. Artificial cultivation of Saussurea has become an urgent need in the market. However, in the process of artificial cultivation, due to the special growth habits of Tianshan Saussurea, the requirements for the growth environment and its own fragility make artificial cultivation encounter many difficulties, making it difficult to industrialize and large-scale plant Saussurea. One of the main reasons is that the germination rate of Saussurea seeds is low, the growth is slow, and the survival rate of seedlings is low. Summary of the invention
