Mulberry is a deciduous tree or shrub, with a height of more than 3- 10 m, a DBH of 50 cm, a thick gray bark 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.
Flowers unisexual, axillary or axillary in bud scales, born at the same time as leaves; Male inflorescence pendulous, 2-3.5 cm long, densely white pilose, male flowers. Perianth wide oval, light green. Filaments folded in bud stage, anthers 2-loculed, spherical to kidney-shaped, longitudinally dehiscent; The female inflorescence is1-2cm long and hairy, the total pedicel is 5 5- 10/0mm long, the female flower is sessile, the tepals are obovate, the tip is blunt, the outer surface and edge are hairy, the two sides of the ovary are tightly clasped, there is no style, the stigma is 2-split, and the inner surface has papillae.
Chrysanthemum fruit is oval, long1-2.5cm, and red or deep purple when ripe. The flowering period is April-May and the fruiting period is May-August.
Mulberry likes warm and humid climate and is slightly tolerant to 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.
The defoliation of mulberry leaves in winter is its growth law, and new leaves will grow next spring, but in addition to normal leaves, plants will also defoliate because of low temperature or insufficient light.
Mulberry is a deciduous tree belonging to Moraceae. Its shape is very different from that of poplar, but it will begin to shed leaves in cold winter.
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.
The in vitro experiment of fresh mulberry leaf decoction showed that it had strong antibacterial effect on Staphylococcus aureus, hemolytic streptococcus B, diphtheria Bacillus and Anabaena, and also had certain antibacterial effect on Escherichia coli, typhoid Bacillus, Shigella dysenteriae and Pseudomonas aeruginosa. This soup can also kill leptospira.
