How to store flower seeds and control diseases and insect pests of edible fungi

After the seeds were harvested and dried, the full seeds were selected and stored free of diseases and insect pests. Attention should be paid to classification during storage to avoid mixing with each other. The life span of flower seeds varies according to seed maturity and storage conditions. Some seeds can not be stored, once stored, they lose their germination rate, such as seedling begonia and so on. In general, the vitality of flower seeds can be maintained for 2 to 3 years or more. If the storage time is too long, not only the germination rate will be reduced, but also the growth ability after germination is poor.

The storage of flower seeds should pay attention to the following aspects:

Keeping dry is an important condition to prevent seed deterioration. The moisture content should be kept at 12% in order to stabilize the life activity of the seed. Once the seed moisture content is found to be too high, it should be turned into the sun immediately to prevent it from heating, mildew and freezing.

Controlling the high temperature will enhance the respiration of seeds and directly affect the quality and germination rate of seeds. Preservation under the condition of 2 ℃ ~ 3 ℃ can reduce the respiration rate of seeds, thus maintaining the long vitality of seeds.

Clean seed storage rooms should be cleaned, cracks and rat holes should be plugged with lime, walls should be brushed with lime water, and then disinfected with appropriate amount of chemicals. After drying, the seeds collected and stored in the family can be hung in a ventilated and dry place with a cloth bag, which is a better method of storage.

With different storage methods, some seeds are suitable for wet storage, such as Phyllostachys pubescens, papaya, peach blossoms, plum blossoms, roses, etc., while the seeds of water lilies and jade lilies need to be stored in bottles filled with water. Peony, rose, sweet-scented osmanthus and other seeds need to be stored in sand; others need to be stored by frozen methods, such as duck tail, swallows, stachyons, etc.; the seeds of peony and magnolia should be harvested along with the seed; and some drupes and seeds with a hard seed coat should be stored in a pit (a layer of horse dung, a layer of soil and a layer of seeds) and sealed.
