How to process Schisandra seeds? Detailed explanation of the correct processing method
After the Schisandra fruit ripens and is harvested, select plump, large, disease-free Schisandra fruits, soak them in warm water (40-45°C) for 3 days, rub off the flesh, pick out the seeds, then use water separation to remove the shriveled grains, and store them in a ventilated, dry place. After drying, carry out stratification. The stratification method is to fully mix the prepared seeds with 3 times their mass of wet sand; the sand's moisture level should be such that it does not form a ball when squeezed by hand. Dig a pit trench of 60cm×60cm×60cm, with the seed-and-sand mixture at a thickness of 40cm, cover with 15cm of soil, then cover with a

How to Treat Licorice Seeds? A Detailed Guide to the Correct Method
The methods currently used in production are as follows: (1) Sand abrasion method: mix licorice seeds with clean river sand at a 1 to 1 ratio, put them into a container, and stir repeatedly so that they rub against each other; sow once the seed coat is no longer shiny. This method is labor-intensive and is only suitable for treating a small quantity of seeds. (2) Rice milling machine treatment: grind the licorice seeds with an electric rice milling machine for 2-3 passes, until the seed coat is scratched but the kernel is not broken. (3) Warming and repeated soaking method: soak the seeds in 60°C warm water for 6-8 hours, and use the "rice-washing method" to float off the seeds in the upper layer that have already absorbed water; then take the
