Mulberry (Latin name: Morus alba L.) is a deciduous tree or shrub of Moraceae, and its height can reach15m. This tree is rich in milk pulp and its bark is yellowish brown. The leaves are ovoid to broadly ovoid, with sharp, round or shallow heart-shaped leaves at the base, rough serrated edges and sometimes irregular division. Leaves are glabrous and shiny, and there are sparse hairs on the dorsal veins of leaves. Dioecious, flowering in May, _ _ _ _ _ _. The fruit ripens from June to July, and the flowers and fruits are oval or cylindrical, dark purple or white. I like light, but I was a little tolerant of shade when I was a child. Like warm and humid climate, cold-resistant. Strong drought resistance, water and humidity resistance.
Morphological characteristics: trees or shrubs, 3- 10 meters high or higher, DBH up to 50 cm, thick bark, gray, with irregular shallow longitudinal cracks; Winter buds are reddish-brown, oval, with tile-shaped bud scales, gray-brown and fine hairs; Branchlets have fine hairs. The leaves are ovoid or broadly ovoid, 5- 15cm long and 5- 12cm wide. The apex is acute, tapering or obtuse, the base is round to shallow heart-shaped, the edge is rough and obtuse, sometimes the leaves are divided, the surface is bright green and hairless, the back is sparse along the veins, and there are tufts of hairs in the axils of the veins. Petiole length 1.5-5.5 cm, pilose; Stipules lanceolate, caducous, densely setose outside.
Pest control: use dichlorvos, dimethoate and mulberry once after spring silkworm germination, and use dichlorvos, dimethoate, mulberry, carbendazim and thiophanate-methyl to control pests after spring silkworm, summer silkworm and early autumn silkworm.
Origin and Habitat: This species is native to north-central China, and has been cultivated from northeast to southwest provinces and northwest to Xinjiang. North Korea, Japan, Mongolia, Central Asian countries, Russia, Europe and other places, as well as India and Vietnam are also cultivated.
Growth habit: like warm and humid climate, slightly tolerant of shade. Germination begins when the temperature is above 65438 02℃, and the suitable temperature for growth is 25-30℃. When it is higher than 40℃, it will be inhibited, and when it is lower than 12℃, it will stop growing. Drought tolerance, waterlogging tolerance and barren tolerance. Strong adaptability to soil.
Economic value: Mulberry leaves can disperse wind and heat; Clearing lung; Clean your eyes. Main wind-heat cold; Early onset of wind temperature, fever, headache, sweating, cough, chest pain; Or lung dryness, dry cough without phlegm; Dry throat and thirst; Wind-heat and hyperactivity of liver yang; Eyes are red and swollen.
Toxicity: The safe dose of 10% Mulberry Leaf Injection to mice (weight 20g) after intraperitoneal injection 1 is equivalent to 250 times of human dose. Continuous intraperitoneal injection of 2 1 day into mice at a dose of 60 times that of human beings has no harm to liver, kidney and lung. If a larger dose is given, the above organs will degenerate and bleed.
