Embodiment Construction

[0010] According to the above-mentioned technical scheme, soak the naturally mature seeds of the wild Northeast hard comfrey in cold water for 24 hours, remove the seeds and stir them evenly with river sand with a particle size smaller than the seeds, and mix them with a portion of seeds in a ratio of 2:1. Two parts of river sand, after mixing, put the sand and seeds into a woven bag, lay it out flat, cover it with barley and freeze it at minus 18°C ​​to 24°C for 10 days to complete the domestication process of the comfrey seeds. Because the maturation of comfrey seed embryos is divided into two stages, the first stage is that the seed embryos develop naturally during the growth period, and the second stage is that the seed embryos complete the late maturity in the shell. Enter enough water and oxygen to activate the cell tissue. After the seed is domesticated, the late maturation of the embryo can be completed, ensuring one-time sowing of preserved seedlings. Sowing in spring...

Abstract

The present invention relates to northeast lithospermum erythrorrhizon producing process. The great area planting process includes the following steps: soaking lithospermum erythrorrhizon in cold water for 24 hr, mixing with river sand, freezing in sodium soil bed at -18--24 deg.C for 10 days to crack seed shell and complete seed domestication, planting in proper sand soil, collecting seed while leaving stalk of 15-18cm length, and collecting northeast lithospermum erythrorrhizon root in 30 days after collecting seed. Northeast lithospermum erythrorrhizon contains rich effective elements and is used in producing red pigment and health product.

Description

technical field [0001] The invention relates to a production method of Northeast hard comfrey, which is used for planting comfrey in a large area. Background technique [0002] In 1982, the World Health Organization called on scientists from various countries to replace chemically synthesized pigments with natural plant pigments as soon as possible. Scientists from various countries recognized that comfrey was the best raw material to replace chemically synthesized red pigments. Because comfrey red pigment has bright color, high color value, strong coloring ability, and has stable properties such as light resistance, heat resistance, oxidation resistance, and pH resistance, it can be widely used in coloring in industries such as food, beverage, cosmetics, medicine, printing and dyeing, etc. agent. According to the detection and analysis of Shanghai Institute of Plant Physiology, Chinese Academy of Sciences, it is confirmed that comfrey seeds contain a large amount of supero...
