How to understand the sowing, reproduction and nursing of Chrysanthemum morifolium

White crystal chrysanthemum is propagated by sowing, usually in September to October in autumn, and the suitable temperature for germination is 15℃ to 20℃.

White crystal chrysanthemum. When sowing, after sowing, it is appropriate to shade with reed curtains and not to cover them with thin films. Mix the seeds with a small amount of fine sand or culture soil and spread them on the seedbed or seedling tray. The thickness of the soil should not be seen. Keep it moist and germinate in 5 to 8 days. After the seedling slightly topdressing, promote seedling growth robust, grow two or three leaves when the first sub-planting, bare roots without soil. After growing 4 to 5 true leaves, they are transferred to seedbeds or nutrient bowls for cultivation. At the end of October, irrigate once permeable water. When the soil is not sticky or scattered, store people in the sunny bed for winter. Cover the cattail mat at night to prevent cold. Although the white crystal chrysanthemum is cold-resistant, it is better to put the seedlings in the plastic greenhouse or cold room in winter to continue to grow. Water and fertilize in time, remove the buds in time, and promote them to increase the crown diameter. Move them outdoors or flower beds in early spring next year to increase their ornamental effect. Like warm, cold, like light, but also resistant to semi-shade, growth temperature 15~25 degrees.

After one or two transplants in autumn, flower beds can be planted directly when flowers are seen in spring. After autumn seedling division without reverse bed transplant, spring should be added enough base fertilizer in the bed after maintenance molding, into the flower bed planting or out of the nursery market. When planting, apply decayed leaf fertilizer or stable as base fertilizer, plant spacing 15 cm. After planting, it is advisable to water once every 7 to 10 days. Fertilization does not have to be too frequent, every 2- 3 weeks to apply a thin manure water, once a month, until February after flowering, stop fertilization.

Another: white crystal chrysanthemum growth period like sunshine, not tolerant of shade. White crystal chrysanthemum autumn sowing to promote strong, if there is no sub-seedling transplantation, can be at the end of October seedlings out, separate, root clusters with a little bit of soil, and then grasp-prepared in advance containing more humus and slightly sticky moist fertile soil, put-two seedlings in the center of the loam tightly into a lump, in turn stored into the Yangqi, spray moisture, to promote the growth of fibrous roots, small plants strong, in spring directly planted flower beds or listed for sale is not easy to wilt. Tips: white crystal chrysanthemum in summer hot period flowering bad, easy to die, such as digging transplant cool place, to be able to bloom again in autumn.

Cultivated soil rich in organic matter to fertile loam or sandy loam best, drainage, sunshine needs to be good, insufficient sunshine flowering bad. Cultivate soil at ordinary times to keep moist, drought fertility is not good. Cut off the remaining flowers immediately after the flower withers, which can promote the new buds to bloom again. Sexual warmth, avoid high temperature and humidity, suitable temperature for growth 15~25 degrees C, pay attention to avoid long-term moisture caused by decay in plum season, and prolong flowering.

Autumn sowing in warm areas, mainly spring sowing in North China, seed germination temperature of 15-20 degrees. 5-8 The sky sprouted. Flowers bloom 11-12 weeks after sowing.

The sowing method is used for reproduction. Autumn and winter are the sowing periods in Taiwan flat land. Spring sowing can also be carried out in high cold land. The optimum temperature for seed germination is 15~20 ℃. The seeds mixed with a small amount of fine sand or culture soil, and then evenly spread on the seedbed, covering a little soil above, maintain humidity, about 5 to 8 days to germinate. When the leaves have 5~7 buds, move them into flower beds with plant spacing of 15-20 cm, or plant them in 17 cm pots. The flower bed large-area cultivation may also adopt the direct seeding method, first prepares the soil, pre-embeds the base fertilizer, then scatters the seed in the soil surface, waits for the seedling to see the plant spacing to make the transplant or the interplanting.

conservation and pest prevention

White crystal chrysanthemum due to long flowering period, growth period or flowering period every 20-30 days topdressing once, so usually culture soil to keep moist, flowers immediately after the cut off residual flowers, can promote new buds to bloom again.
