Introduction:
Chrysanthemum repens is an annual perennial herbaceous flower. Since it is dried and does not fall out, it is made from wax and is a good material for making dried flowers. It is a natural “handicraft†unique to nature.
The species of the same genus are sand-scented chrysanthemum, parachute, etc. Perennial herbs are cultivated for one year, with low resistance to cold, and the frost will die. Planting land should be good for sunshine, water conservation, drainage, and land with good fertility. Flower diameter 5 ~ 6CM, stem hard, rich colors, red, peach, yellow, white and intermediate colors.
Origin:
Native to Australia, it is cultivated in many countries in the world.
Morphological characteristics:
Plant height 50-90 cm, stems more branches, the whole plant was hairy. Leaves alternate, strips lanceolate, entire, leafless. Heads solitary shoots. The total sepals are multi-layered, membranous and imbricate, and the outer sepals are short. The internal sepals are elongated and resemble tongue-like flowers. They are white, yellow, orange, pink, red and dark and are often mistaken. Think of petals. Small yellow tubular flowers accumulate in the center of the disk. Achene gray brown, smooth.
Flowering period 7 - September.
Growth habits:
Chrysanthemum sex warm and sunny environment. Not cold, avoid heat, grow well on moist and well-drained fertile and loose soil.
Germination temperature: 15-20 °C
Growth temperature: 12-25°C
Soil: The adaptability to soil is strong. Generally, the soil can be planted, but it requires good drainage.
Moisture: water should not be too much, otherwise the plant is tall, flowering later, avoid moisture.
Sunshine: hi sunshine, lack of sunlight affect flowering.
Fertilizer: Fertilizer is applied once every half-month in growth period, and phosphorus and potassium fertilizers are applied twice in flowering period.
Temperature: warm, but also resistant to cold. The appropriate temperature for sowing is 20-22 degrees, and the suitable temperature for growth is 20-30 degrees.
application:
Can be arranged flower bed flower environment, can also be potted ornamental, in addition it can be used for dry flowers, cut flowers and flower arrangements.
About 350 species of the same genus are presently cultivated:
1 Geranium, with spreading stems, leaf obovoid, capitate silvery white, native New Zealand;
2 Umbrella Flowers Chrysanthemum, shrub-like base, leaves oval, head-shaped inflorescences umbrella-like room, the total sepal oblong, apex obtuse, milky white. Native South Africa;
3 Tianshan chrysanthemum, a perennial herb, densely covered with villi, leaves narrowly lanceolate, head-shaped inflorescences corymbose, yellow or orange, native to Xinjiang, China.
This kind of straw-like chrysanthemum-like golden sun is dazzling and very moving. It is commonly planted in flower beds in Lingnan.
Safflower yellow can significantly inhibit ADP-induced platelet aggregation in rabbits, and also has a very obvious depolymerization effect on ADP-aggregated platelets. When the dosage was 0.22g/ml, the inhibition rate of aggregation and depolymerization reached 85.9% and 78.9% respectively. These effects of safflower yellow were enhanced with the increase of dosage. Safflower yellow has a very significant inhibitory effect on experimental thrombosis in rats, the inhibition rate is 73.4%. Because the thrombus material formed on the silk line is platelet aggregates, the reduction of wet weight of thrombus is obviously the result of drug inhibiting platelet aggregation. It is consistent with in vitro experiments that safflower yellow can inhibit platelet aggregation induced by ADP. Safflower yellow also significantly prolonged plasma recalcification time, prothrombin time and coagulation time in rabbits. It shows that it can affect the coagulation system both in vivo and in vitro. In addition, safflower oil can reduce blood lipid.
