Matters needing attention in rehydration of edible fungi and storage technology of herbaceous flower seeds

Key points of storage technology

Choosing the right packaging method, the number of flower seeds is generally small, the life is short and the price is expensive. In most cases, polyethylene aluminum foil composite film bags are used, and the jacket is generally paper seed bags. Flower seeds containing aromatic oil should be stored in metal cans, wooden boxes or colored glass bottles. The name of the seed and the year, month, day and service life of the harvest should be correctly marked outside the seed bag.

Seeds stored at low temperature and moistureproof after cleaning and drying to safe moisture content and packed in aluminum foil bags or metal cans should be stored in dry, sealed, low temperature (2 ℃-5 ℃) conditions. The seed bag or jar should be placed on a shelf or table about 50 cm from the ground. Do not contact the seed bag directly with the ground to prevent moisture. A small amount of seeds can be stored in a dryer. The dryer can use glass bottles, small mouth covered urns, plastic buckets, etc., with quicklime, silica gel, dried plant ash and charcoal at the bottom as desiccant, seed bags on top, and then sealed and placed in a low-temperature drying place.

Management measures of Flower seed Storage

Warehouse clearance and disinfection: remove garbage, chemical fertilizers and pesticides in the warehouse, and lay felt paper as a moisture-proof layer in the warehouse to reduce the absorption of ground moisture by seeds. Diluted with 80% dichlorvos EC and sprayed, the doors and windows were closed for 48-72 hours and ventilated for 24 hours. Don't use smoke compartments.

Reasonable stacking: there are many varieties and grades of flower seeds, but the general number of seeds is not large. In the warehouse, it should be placed on a shelf about 50 centimeters away from the wall and 50 centimeters from the ground. Make a sign indicating its location, quantity, packaging, etc., to prevent confusion.

Timely ventilation: seed respiration produces a lot of heat, timely ventilation can cool down and dissipate humidity. Generally to "clear rain closed snow can not pass, dripping water into ice can be encountered, open early in the evening, less open at noon, night fog can not open" as the principle. Ventilation is mostly natural ventilation, conditional mechanical ventilation is available.

Diligent inspection: the warehouse should check in time and check the water content and germination rate of seeds after summer or winter. Set up temperature and humidity meters at multiple points in different parts of the warehouse, set people to measure regularly, and make records. Flower seeds must be stored in a low-temperature and low-humidity environment to prevent mildew or decrease in germination rate.
