In the process of flower and tree production, the picked seeds are stored in winter for the next year or poor harvest. If improperly stored, seeds can easily lose their vitality. Therefore, suitable storage methods should be adopted for the storage of flower seeds in winter.
After the dry storage method, the seeds are fully dried, put into sacks or buckets, cabinets, and placed in indoors or cellars. The temperature can be maintained at 0.5 ° C ~ 1 ° C, and the relative humidity can be 50% ~ 60%. First dry the seeds, remove their impurities, and put them in a gauze-sewn bag. Hang the seed bag in a cool and ventilated place in the room, and keep the room temperature between 5 ° C and 10 ° C.
There are three common wet storage methods for wet storage: One is the water storage method. The seeds are packed in bags and stored in running water. The seeds must be stored clean and free of silt and rotten grass. Use wooden stakes around the seeds to prevent them from being washed away by water. The seeds of aquatic flowers such as lotus, water lilies, water hyacinth and oak trees are suitable for the water storage method. The water storage method can only be used in places where the river water is not frozen in winter, otherwise the seeds may be easily damaged. The second is wet sand burial. The seeds are buried in wet sand for storage. The humidity of the sand should not be too high. The temperature should be controlled at 2 ℃ ~ 3 ℃. The sand storage time varies depending on the type of flowers and trees. This method should not be used for small seeds because it is difficult to remove the sand. Choose out. However, it should be noted that the covered sand should not be too wet to prevent mildew, and the room temperature should be kept at 5 ℃ -10 ℃. If it is too high, it will germinate and if it is too low, it will cause frost damage. The third is the pit method. Dig a pit of 1-1.5 meters deep in the back, with high terrain, dry soil, and loose soil. The length and width depend on the number of seeds. Lay a layer of stone or coarse sand on the bottom of the pit, and then a layer of coarse sand and a layer of seeds When stacked, the humidity of the sand should be held in a hand, but it should not be out of water. To prevent mold seedlings, a straw or sorghum stalk is erected every 1 meter to facilitate ventilation and heat dissipation.
