Leaves membranous, lanceolate to elliptic-lanceolate, 6-14 cm long, 1-4 cm wide, apex short-acuminate or acute, base wedge-shaped and descending to petioles, ** or slightly hairy in veins;Lateral veins about 8 on each side;The petiole is 05-1 cm.
The inflorescence is apical or axillary, with 10-20 flowers;Calyx lobes lanceolate, pubescent;Corolla purplish-red, lobes oblong, 5 mm long, 3 mm wide, folded back;The secondary corolla is born on the corolla of the zygostasis, 5-lobed, yellow, spoon-shaped, sessile, with tongue-like lobes inside;The pollen masses are oblong, drooping, and have purplish-red powder glands. The follicles are lanceolate, 6-10 cm long and 1-1 in diameter5 cm, tapering at both ends;The seeds are ovate, about 6 mm long and 3 mm wide, with white silk seed hairs at the apexSeed hair length 25 cm. The flowering period is almost all year round, and the fruiting period is from August to December.
Growing Environment:Milkweed likes warm, humid climate, likes fertilizer, light, more drought-tolerant, and the soil requirements are not very strict, but the soil layer of fertile soil, sandy loam soil grows robust, and long-term water accumulation is not conducive to its growth.
Distribution:Native to the West Indies of Latin America. It is widely planted in various tropical and ** regions of the world. It is cultivated in Guangdong, Guangxi, Yunnan, Guizhou, Sichuan, Hunan, Jiangxi, Fujian, Taiwan and other provinces and regions in China, and is also wild and domesticated.
Key Values:
Watch:Strong nature, colorful flowers, high ornamental value, potted plants are suitable for balconies, rooftops or courtyards on the roadside, in front of the window;In the garden, it is often used for flower beds and flower cultivation and ornamentation in green spaces.
Medicinal:The whole plant is toxic, especially the milk toxicity is strong, containing cardiac glycosides, called leukomicrosides, which can be used for medicinal purposes, the whole herb and the root are used as medicine, which can remove deficiency heat and facilitate urination, regulate menstruation, promote blood stasis, reduce inflammation and relieve pain, clear heat, reduce fever, detoxify, disperse swelling and repel insects.
Cultivation and planting techniques
Land selection and land preparation
Choose a thick soil or sandy loam land, plough with a depth of 15-20 cm, apply 1500-2000 kg of fully decomposed manure per mu, sprinkle evenly and ridge.
Sowing and transplanting
The method of live broadcast is mainly hole sowing, the hole distance is 20-25 cm, each hole has 3-4 seeds, and the hole depth is 15-2 cm, covering soil 1-15 cm, slightly suppressed. Sowing time: Late April to early May. Under normal conditions (temperature above 15, soil moisture above 30%), seedlings emerge in about 15 days, and the emergence rate can reach 90%. Seedlings can also be transplanted. The seedling raising time is mid-March, and the transplanting time is in early May, with a plant spacing of 20-25 cm, and 1 plant per hole.
Field management
Direct seedling seedlings grow 2-3 pairs of true leaf time seedlings, leaving 1 plant per hole, and the average number of seedlings can continue to be transplanted. Weeding and loosening are regular field management tasks with proper soil plugging at the base. With the increase of temperature and the right amount of watering, the growth of plants accelerates, and the roots are topdressed once from late June to early July. Nitrogen, phosphorus and potassium compound fertilizer are the mainstay, 20-25 kg per mu. In the rainy season, it is necessary to strengthen the field drainage work, and loosen the soil in time after the rain to enhance the air permeability of the soil and effectively control the occurrence of root rot.
