-Overview-All over the sky In China, there are mainly two kinds of herbs with many small flowers, namely, annual perennial Dianthus chinensis (G. elegans) and perennial perennial Dianthus chinensis (G. paniculata). Originated in Eurasia. Silk flower is as high as 50 cm (20 inches); Branched; The leaves are narrow and blue-green; Widely cultivated, the common varieties are "carmine" (deep rose red) and "big white flower" (big white flower; ; Flowers are big and white) and "Rosea" (flowers are light rose). The sky is full of stars as high as 1 m (40 inches), which looks like silk flower, but has thick roots and white to pale pink flowers; Common varieties are "Compacta flower", "Flore Pleno" and "Grandiflora".

Mantianxing-Broken copper coins (20 pieces) like warm, humid and sunny environment, and are more resistant to shade and cold, and grow best in fertile and loose loam with good drainage. The cultivated soil is slightly alkaline calcareous loam, which needs good drainage and sunshine. If the height of the plant is more than 20 cm, the irrigation amount should be reduced appropriately. A slight drought can promote flowering, especially after flowering, poor drainage or long-term rain, and the roots are easy to rot. Sexual preference is warm, avoiding high temperature and humidity, and the suitable reproductive temperature is 10-25℃. The optimum temperature for propagation and cultivation germination is 15-20 degrees. Sowing date: early autumn-early spring. Optimum growth temperature: 10-25 degrees. Flowering: May-July. Seedling raising: loose soil is selected as the bed, sowing is carried out in September, slightly covered with fine soil, germination lasts about 10 days, and it is moved to a cold bed for wintering in winter. Cultivation: Transplanting in the open field with soil in the next spring, coring once after the seedlings are planted and survive, so as to promote their multi-branching. When the plant height is more than 20 cm, the irrigation amount should be reduced appropriately, and a little drought can promote flowering. It blooms in the middle and late May, and can also be planted directly in the open field or sown in early spring before freezing in June165438+1October. Cutting propagation is the main method. Hardwood cutting is carried out in spring, and the mature branches of the previous year are cut into 10- 15 cm long, inserted into the sand bed, and potted to the sky.

It usually takes about 30 days to take root. Softwood cutting can be used in rainy season, and the top softwood cutting in that year can take root 2-3 weeks after cutting. When changing pots every spring, add fresh and fertile soil, keep the soil moist during the growing period, and apply fertilizer every two weeks 1 time to promote more lush foliage. Pay attention to pruning the whole plant in autumn to maintain a good plant shape. The pests and diseases of gypsophila paniculata are mainly caused by leaf spot, and 65% zineb wettable powder 600 times can be sprayed. Insect pests do great harm to aphids and red spiders, and spraying 40% omethoate EC 1000 times. Pests and diseases prevent stem rot, and atrophy is a fatal disease of gypsophila. Disinfect the soil with formaldehyde solution before planting. Pests are mainly mites and aphids, and dicofol 1000 times and pyrethroid 1500 times can be sprayed. Usage: The sky in early summer is full of white flowers, which are lush, meticulous and evenly distributed. Like stars, hazy and charming, and like snow-covered trees, beautiful and lovely, it is suitable for planting flower beds, roadsides and hedges, and is also very suitable for potted viewing and bonsai making.

Edit the background knowledge of botany in this section.

Gypsophila paniculata is a typical diurnal plant with a single wild floret, which is propagated by seeds. Spring flowers sown in autumn are all over the sky.

Typical characteristics of Japanese plants. Wild species of gypsophila paniculata have small petals and low commodity value. They are mostly used as breeding materials and rarely used for commercial cultivation. At present, the double-petal varieties cultivated as cut flowers are all improved by breeding, and the best propagation method is tissue culture (cloning). The offspring are neat and stable, and the excellent characteristics of the mother are well preserved. Through the efforts of breeders at home and abroad, several varieties that are insensitive or slightly sensitive to the length of sunshine have been improved, which has laid a good foundation for perennial cultivation and supply of cut flowers from all over the sky. At present, the mainstream varieties of cut flowers in Kunming-precocious Dahua (insensitive to day length) and Baixue (slightly sensitive to day length) are two budding strains selected from the perfection of old varieties by Mr. Liu Jiaxun of Yunnan Yike Flower Company, which have been used for tissue culture and mass propagation.
