Species name: Sophora japonica

Sophora japonica and Platycladus orientalis have become the city tree of Beijing. At the same time, Sophora japonica is also the city tree of Dalian City, Liaoning Province and Tai'an City, Shandong Province. [Edit this paragraph] Name English name: Flower of Japanese Pagodatree, Pagodatree Flower Bud

Latin literary name: Sophora japonica Linn.

Origin of name: Sophora japonica tree, with pinnately compound leaves and smaller leaflets, so The canopy is dense. The first-level lateral branches of the locust tree are thick, giving the tree a cloud-like crown. The locust tree has rhizobia and sufficient nitrogen nutrition, so its leaves are dark green. From a distance, the crown of the locust tree looks like a dense dark green cloud. Dark green is a dark color, and thick clouds will also bring darkness. The locust tree is shrunken in the shape of a string of beads, and the shrunken area is very thin. The pod corners of the locust tree remain on the tree. During the rainy season of the second year, when it rains, the pod corners are soaked by the rain and break and fall. The peel is soaked and rots, revealing the seeds, dyeing the ground under the shade of the tree dark green. Sophora trees are susceptible to aphids, and aphids' secretions will dye the ground black when they fall on the ground. Therefore, the shade of locust trees often appears black, which also has a gloomy meaning. Therefore, the name of the locust tree comes from "obscurity". The pronunciation of the word "槐" is similar to the word "hui". "槐树" means "hui tree", which means a type of tree with a dark crown.

But it grows best on moist, fertile, deep, well-drained sandy soil. It is resistant to smoke and dust and can adapt to the urban street environment. There are not many pests and diseases. Long life and strong resistance to smoke poison. [Edit this paragraph] Garden uses Characteristic tree species commonly used in Chinese gardens. It has strong fast-growing properties, hard material, elasticity, straight texture, easy processing, and corrosion resistance. The buds can be used as dyes, the pulp can be used as medicine, and the seeds can be used as feed.

[Edit this paragraph] Propagation and cultivation are mainly sowing and propagating, and cuttings can also be used. For spring sowing, because the seed coat has a fence layer with cells that are closely connected and has poor water permeability, before sowing, soak the seeds in water with an initial temperature of 85-90 degrees for 24 hours, and then process the remaining hard kernels 1-2 times. The seeds swell when they absorb water and can be sown.

The spacing between rows is 20-25 cm, the soil cover thickness is 1.5-2 cm, the seeding rate per acre is 8-10 kg, and the seedlings are unearthed in 7-10 days. During the seedling stage, they should be planted reasonably densely to prevent the trunks from bending. Generally, 6-8 seedlings per meter will be left. Annual seedlings are more than 1 meter tall. The seedlings can also be grown in concentrated nutrient pots in early spring and then transplanted to establish the seedlings. Sophora japonica has strong germination ability. If the seedlings are cultivated to form a good stem shape, they can be cut in the early spring of the second year and the spacing between the rows can be increased. The seedlings will be 3-4 meters high that year, and the trunks will be straight, thick and smooth. [Edit this paragraph] A nectar plant with excellent economic uses; the seeds are pressed for oil for industrial use; the exocarp of Sophora japonica can be used to extract sugar, etc.; the wood is used for construction or making farm tools and furniture; it has strong resistance to toxic gases such as sulfur dioxide and chlorine. resistance. [Edit this paragraph] Medicinal value Sophora japonica is cool in nature and bitter in taste. It has the functions of clearing away heat and cooling blood, clearing liver and purging fire, and stopping bleeding. It contains rutin, quercetin, sophorodiol, vitamin A and other substances. Rutin can improve the function of capillaries, maintain normal resistance of capillaries, and prevent bleeding, high blood pressure, and diabetes caused by excessive capillary fragility and high permeability. Taking it can prevent bleeding; Sophora japonica can stop bleeding and lower blood pressure. pressure.

Cut the branches of Sophora japonica into small sections, boil it until the liquid turns green, smoke it first and then wash the hemorrhoids, which has a good therapeutic effect.
