The specific method is:
First, the onion seeds harvested in the year were carefully selected to remove pods and impurities, and fully dried to reduce the moisture content of the seeds to 10%;
Second, the air-dried weathered coal was crushed through a fine sieve, placed in an iron pan and fry until dry, and then ceased to cool until the temperature of pulverized coal was around 30°C;
Third, according to the proportion of weathered coal with three seeds, the above seeds were mixed with weathered coal and immediately put into high-density polyethylene plastic bags or barrels, sealed tightly and placed in a dry dark place. If seeds are to be taken during storage, follow them with seal. When sowing, weathered coal can be sown together, but also play a role in promoting seedlings and strong.
Weathered coal can extend seed storage life
When the seeds of scallions, onions, leeks, etc. are stored at room temperature until the second year, the germination rate drops below 50%. How do you prolong the storage time of these vegetable seeds? Weathered coal was used as a moisture absorbing agent for storage. The germination rate of the onion species that was stored for three years still reached 86%, and the germination rate was still more than 70% after five years of storage.
