Broussonetia papyrifera is a Moraceae plant.

The leaves are arranged in a spiral shape, ranging from wide ellipse to long ellipse, with a length of 6- 18cm and a width of 5-9cm. The apex is tapered, the base is heart-shaped, the two sides are often unequal, the edges are coarsely serrated, the leaves of small trees are often obviously divided, the surface is rough, sparse and rough, and the back is densely villous, with 3 basal veins and 6-7 pairs of lateral veins. Petiole 2.5 to 8 cm long, densely strigose; Stipules are large, oval and narrow, with a length of 1.5 to 2 cm and a width of 0.8 to 1 cm.

Flowers dioecious; Male inflorescence is catkin, stout, 3-8 cm long, with lanceolate bracts, hairy perianth, triangular ovate lobes, hairy stamens, nearly spherical anthers and small degenerated pistil; Female inflorescence is spherical, capitate, bracts clavate, hairy at the top, perianth tubular, near the style at the top, ovary ovoid, stigma linear and hairy.

The diameter of Juhuaguo is 1.5 to 3cm, and it is orange-red and fleshy when mature. Achene has an equal-length stalk, a small tumor on the surface, a double dragon bone shape, and a hard shell on the exocarp. The flowering period is April-May and the fruiting period is June-July.

It likes light, has strong adaptability, is drought-resistant and barren-resistant, and can also be born near water, mostly in limestone mountains, and can also grow on acidic soil and neutral soil; Strong smoke and dust resistance and air pollution resistance.

Broussonetia papyrifera can resist toxic gases such as sulfur dioxide, hydrogen fluoride and chlorine, and can be used as greening tree species in barren beaches, remote areas and heavily polluted factories. It can also be used as a street tree and paper making. The protein content of Broussonetia papyrifera leaves is as high as 20% to 30%, and it is also rich in amino acids, vitamins, carbohydrates and trace elements. After scientific processing, it can be used to produce full-price livestock feed.

Young leaves can be fed to pigs. Made of Broussonetia papyrifera leaves as the main raw material by fermentation, without pesticides and hormones. The Broussonetia papyrifera leaf feed produced by biotechnology fermentation has a unique flavor. Pigs like to eat it, sleep after eating it, and are willing to grow. According to different pig breeds and growth stages, the feed digestibility is above 80%.
