Manglietia insignis is an endangered species. Manglietia insignis is an evergreen tree, up to 30 m tall, diameter 40 to 60 cm at breast height. General late spring leaves, strong big and small, seeds by the spread of birds. Manglietia insignis is distributed in evergreen broad-leaved forest or mixed evergreen and deciduous broad-leaved forest in Hunan, Guizhou, Guangxi, Yunnan and parts of Tibetan at an altitude of 900 to 2600 m.
Manglietia insignis is an evergreen tree, up to 30 m tall, diameter 40 cm at breast height; Branchlets are glabrous or rust-colored or yellow-brown pilose at nodes when young. Leaves are leathery, oblanceolate, oblong or oblong-elliptic, 10-26 cm long, 4-10 cm wide, apex acuminate or caudate acuminate, tapering from 2/3 below to base, glabrous above, mid veins reddish-brown pubescent or scattering puberulent below; Lateral veins 12-24 on each side; Petiole of manglietia insignis is 1.8-3.5 cm long;Stipules are 0.5-1.2 cm long.
Flowers of Manglietia insignis are fragrant, pedicel stout, 8-10 mm in diameter, from tepals of about 1 cm, with 1 bract off ring mark, tepals 9-12, ocean shipping three slices of brown, the front dyed red or purple, long oval round about 7 cm long, outward of inflection, wheel within 6-9, upright, ivory colored pink, pour egg shaped spoon, 5-7 cm long, a quarter below gradually narrow into claws; Stamens of manglietia insignis are 10-18 mm long, two chambers slightly separated, connectors protruding into a triangular apex, filaments subequal to connectors protruding; Pistils of manglietia insignis are cylindrical, 5-6 cm long, carpels silent, exposed abaxially with shallow furrows. Aggregate fruit is purplish red when fresh, ovate-oblong, 7-12 cm long;Follicles of Manglietia insignis are completely cleft, with papillae.
Manglietia insignis is shade-resistant, likes moist, fertile soil, excellent wood. It was born in mountain broad-leaved forest or evergreen and deciduous broad-leaved mixed forest at an altitude of 1700-2500 meters.
In autumn, the seeds were screened out, the red seed coat was removed, the seeds were washed and dried, and mildew was prevented from affecting the vigor. Store by stratification until early spring sowing. After 1-2 months Manglietia insignis can sprout seedlings, appropriate frame shade shed. When seedlings as high as 20-30 cm can be nursery planting. Forestland selection valley mountainside shade slope moist ground is appropriate.
Manglietia insignis is found in SW Hunan, Guangxi, SW Sichuan, Guizhou (Leigong Mountain, Fanjing Mountain, Anlong), Yunnan (Jingdong, Wulianshan, Honghe, Wenshan), and SE Xizang. They are born in forests at an altitude of 900-1 200 m. Manglietia insignis is also found in Nepal, northeastern India and northern Myanmar.
1. Spray once every 10 days with 0.5% ferrous sulfate solution or 1000 times equivalent amount of Bordeaux liquid.
2. Has the disease of Manglietia insignis, can be used 800 times the special antibacterial liquid spray seedlings, every 7 days to spray a prevention and control.
seedlings unearthed, in the case of not affecting the growth of seedlings, should be less watering, in order to not be conducive to the disease.
The infected strains, immediately with soil excavation, and in the infected strains around the 1 meter range of soil disinfection, agent can be used 50% of benzene to wet powder 1000 times the liquid irrigation.
Weeding and insect control, to ensure that there are no weeds in the seedling, can eliminate part of the eggs and larvae.
Fresh grass trap, with juicy fresh grass or Lettuce leaves cut short, with fresh grass, trichlorfon according to 99.5:0.5 mix into fresh grass bait, into the seedling seedling near, scattered a small pile at a certain distance, trap larvae.
Pesticide control, 50% phoxim cream 1000 times the liquid spray seedling.
1. Trapping and killing with black light before laying eggs in large numbers of female adults.
2. In the adult occurrence period, spray 90% trichlorfon 1000 times liquid.
Dryness and dampness strengthen the spleen. The main epigastric ruffians are in full pain; Accommodation and food are not available.
Manglietia insignis, its leaves are dark green, delicate, leathery, alternate leaves, oblong-shaped oval, oblong-shaped or oblanceolate, luxuriant and beautiful tree shape, gorgeous and fragrant, for rare ornamental species.
Manglietia insignis mainly scattered in nature, but in yunnan qujing city shizong county mushroom mountain has a continuous distribution, about 75 acres, is one of the largest natural community ever found throughout the country, is a rare type of forest, to study the community formation, occurrence and development of law has an important value, and can provide scientific basis for introduction, domestication and artificial breeding. Manglietia insignis is one of the more primitive species in the genus Magnoliaceae. Manglietia insignis is of significance to study the taxonomy and distribution of the genus and the flora of China and adjacent areas.
