After the seeds have matured, they must be timely harvested and dealt with in a timely manner to prevent them from falling, rotting, or losing their germination power. It is theoretically believed that the more mature the seeds are, the better the seeds are harvested and the harvested materials are not yet fully accumulated and physiologically immature, affecting the germination rate. How to collect and store flower seeds? First, the method of harvesting seeds differs depending on the type of flower. Harvesting and storage of dried fruit seeds include dried fruits, pods, pods, achenes, nuts, and other fruits. The fruit is naturally dried before it matures, cracks and releases seeds, or the seeds fall off together with the dried fruit. This type of seed should be harvested before the fruit matures sufficiently, ie before it cracks or falls off. Some flowers, such as semi-branch lotus, impatiens, pansy, etc., have a long duration of flowering and fruiting. Fruits ripen and scattered as soon as they are late, and must be harvested from plants that are still flowering. After the dried fruit seeds are harvested, they should be placed in a ventilated place for 1 to 3 weeks to allow them to air dry as soon as possible, controlling the moisture content to 8% to 15%. In the rainy and high humidity season, it is necessary to heat the seed for rapid drying and high moisture content. The baking temperature should not exceed 32°C. Seeds with low water content should not be higher than 43°C. After the seed moisture content reaches the standard, remove the impurities from the seed and put it into the bag where the gauze is sewn. If there are many seed varieties, label the bag to avoid confusion and hang the seed bag in a cool, ventilated place. Harvesting and storage of succulent fruit seeds Common flesh fruits include berry, stone fruit, pear fruit, and citrus fruit, such as clivia, pomegranate, coral cherry, honeysuckle, privet, holly, genus, and mature fleshy fruit. The indicator is the discoloration and softening of the pericarp. The immature is usually green and hard. When mature, it gradually changes to white, yellow, orange, red, purple, black and other colors. The water content increases from hard to soft. After harvesting, the fleshy fruit should be timely harvested, and the ripening fruit will fall or be eaten by the bird worm. If the peel is only harvested after drying, it will deepen the seed's dormancy or be infected by mold. After harvesting the fleshy fruit, put it in the room for several days to fully ripen the seed. Wash the pulp with clean water before rot, and remove the unfilled seeds that float on the surface of the water. The flesh must be washed. otherwise. Easy to grow mold. The washed seeds are dried and then stored. Harvest bulbs, bulbs, underground rhizome bulbs and storage of bulbs, bulbs and other species such as cultivars, cannas, dahlias, etc. Before the frost falls, underground stalks should be dug out of the soil and dried 2 to 3 After a few days, put it in a warm, airy, moist room and cover it with wet sand. However, it should be noted that the covered sand should not be too wet to prevent mildew. The room temperature should be maintained at 5 to 10°C. If it is too high, it will easily germinate. If it is too low, it may cause frost damage. In addition, some seeds should be soaked in water after harvest, such as water lily, the water temperature is generally required around 5 °C, so as to ensure the germination rate. All kinds of seeds harvested in autumn and winter season should not be exposed to sunlight, otherwise it will affect the germination rate. The seeds should be dried and placed in a cool place. Pay attention to moisture, smoke, and rodents. China Agricultural Network Editor
