Flower seed storage method

First, the harvested seeds should be cleaned after harvesting. After the whole plant is pulled out, it is dried and then threshed. Even the fruit is harvested to remove skin, flesh and various appendages. Then put the seeds with husks on canvas, mats, bamboo mats to dry, do not put the seeds on the cement drying field or in a metal container in the sun exposure, otherwise it will affect the vitality of the seeds. The seeds can be placed on canvas, mats, and bamboo mats to dry. Some seeds are afraid of light and can be naturally air-dried. That is, the seeds are placed in a ventilated, sheltered room so that they are naturally dry. The safe moisture content of general herbaceous flower seeds is less than 7%. Second, storage technology points 1. Choose the right packing method. Flower seeds are generally less in number, have a shorter life span and are more expensive. In most cases, polyethylene foil composite film bags are used to coat paper seed bags. Flowers containing aromatic oil should be stored in metal cans, wooden boxes or tinted glass bottles. Canned, aluminum foil bags can also be vacuumed or semi-vacuum when sealed to reduce the amount of oxygen in the container. The name of the seed and the year, month, day and age of the harvest should be correctly indicated outside the seed bag. 2. Low temperature moisture storage. The seeds that are washed and dried to a safe moisture content and packaged in aluminum foil bags or metal cans should be stored in a dry, sealed, low temperature (2-5°C) condition. Seed bags or cans should be placed on a shelf or table about 50 cm away from the ground. Avoid seed bags directly touching the ground to prevent moisture. A small amount of seeds can be stored in a desiccator. The desiccator can use glass bottles, small-mouthed cans, plastic buckets, etc. At the bottom, quicklime, silica gel, dry grass ash, charcoal, etc. can be used as a desiccant, and seed bags can be placed. It is then sealed and placed in a cool, dry place. 3. The strength of seed vitality and the length of seed life of herbaceous flower seeds are closely related to storage conditions. Under the conditions of warm, moist, and unobstructed air, the seeds have a strong vitality. Nutrients in the seed are quickly consumed and the life span of the seed is shortened. In the condition of low temperature, dryness and slow air circulation, the seed life is slow, and the seed life can be relatively extended. Therefore, 1-2 years of herbaceous flower seeds should be kept at low temperature, dry and confined conditions. Preservation of Phlox, Kochia, Primulae for 1 year; 2-3 years of preserved butterfly flower, haloxylin, pansy, marigold, beautiful cherry, aster, daisy, nasturtium, fragrant bowl Bean, Poppy, Cleome, Bunch of Red, Strawflower, Snapdragon, Cornflower; Shelf Life, 4-5 years old, half-branch, zinnia, cinnamon, communis, violet, dwarf Cow, pansy, cockscomb, calendula etc. Third, storage management measures 1. Clearance and Disinfection: Remove garbage, chemical fertilizers and pesticides from the warehouse, and lay linoleum paper inside the warehouse as a moisture barrier to reduce surface moisture absorption by the seeds. Dilute with 80% dichlorvos and spray 48 hours after the doors and windows are closed for 24 hours. Do not use a smoker. 2. Reasonable stacking: There are many varieties of flower seeds and their grades are different. However, the number of seeds is not large. Store in a warehouse about 50 cm from the wall and 50 cm from the floor. Make good signs and mark the location, quantity, and packaging to prevent mixing. 3. Timely ventilation: The seeds breathe a lot of heat, and timely ventilation can cool and loosen the wetness. Generally speaking, it is based on the principle that "the weather is closed by snow, the water is dripping into the ice, and opened early in the morning and opened late, and the fog is not open at night". Ventilation uses natural ventilation and conditional mechanical ventilation. 4. Diligently inspect: The warehouse should be checked in time, and the water content and germination rate of the seeds should be tested after the seeds have passed the summer or winter. Set up temperature and humidity meters at various points in different parts of the warehouse, schedule regular measurements and record well. It is important to keep the low-temperature, low-humidity environment in which the seeds of flowers are stored to prevent the mildew or germination rate of the seeds from decreasing.
