Flower seeds must be harvested at the fruit ripening stage, and timely selection, inferiority, impurity removal, sun dried storage, in order to ensure seed germination. Now we will introduce the collection and storage methods of several flower seeds. (1) Poplar: The seeds are spherical or slightly oval. See the fruit peel skin has dimmed, you can harvest. The pods should be collected in the early morning with moisture, such as harvesting when the sun is strong, the pods are easily split, the seeds are easily dispersed, and after harvesting, when exposed to sunlight, the containers should be covered with glass to prevent cracking of the fruits. Being ejected outside the container. (2) Chrysanthemum Chrysanthemum: When the achene matures, it is during the rainy season in late spring and early summer. It harvests in sunny days in batches, and it is best to seed the seeds first. When the achenes begin to yellow, the harvest can be harvested. , otherwise the seeds will fall off easily and the seed development will last for 4 years. When collecting seeds, pay attention to the fact that Calendula officinalis tends to be degraded. Therefore, special strains should be eliminated and the seeds of inferior plants should not be collected. 3) Winter corals: On the plants that are dignified, robust and have many results, harvest the red ripe berries. After smashing, wash them in water to remove peels, flesh and scorpions. Pick up the plump seeds and dry them for storage. spare. (4) Phloxa: Fruits of different maturation, cracking when mature, in order to prevent seed from falling, when most of the pods yellow, under the total peduncles, dry threshing collection standby, seed germination rate can be maintained for 2 years. (5) Catharanthus roseus: Due to different fruit maturation period, pay attention to observing the yellowing of the fruit in the bones, but when the seeds in the fruit are darkly visible, they should be removed in batches in time. Otherwise, the fruit will crack and the seeds will be scattered. . (6) Pansy: To select the two-year-old robust and beautiful plant as the mother plant. When the fruit is raised, the skin is slightly white, and when the seed turns from greenish white to light brown, it must be harvested immediately. Otherwise, the fruit will be cracked when it is dried in the sun and the seed will be ejected. The causal ripening period varies, so it is necessary to collect the seeds in batches. The seeds of this flower contain large amounts of oil and are susceptible to insects and should be properly collected. (7) Cornflowers: Seeds can be harvested when the inflorescence is just yellow. If the inflorescence is too mature, the seeds are easily scattered. Generally, when most of the inflorescences are yellow, the whole plant is picked up, dried and then threshed and stored in a cool and dry place. Seeds have the ability to broadcast.
