Sophora tree Sophora japonica flower blooming classification: Plants, Fabaceae, deciduous trees, Sophora japonica, cold-resistant plant species name: Sophora japonica Scientific name: Sophora japonica Linn. Alias: Sophora japonica, Sophora japonica: Leguminosae genus : The origin of Sophora genus is distributed in northern China, and it is now cultivated all over China. It can grow in the North China Plain and the Loess Plateau at an altitude of 1,000 meters. Morphological characteristics: Deciduous tree, up to 25 meters high and 1.5 meters in diameter at breast height. Sophora japonica has a huge spherical crown, many branches and dense leaves, a long flowering period and a canopy of green shade. The dry skin is dark gray, the branchlets are green, and the lenticels are obvious. The buds are blue-purple. The flowers are bisexual, terminal, butterfly-shaped, light yellow-green, blooming from July to August, and the fruits mature in October. The pods are fleshy and bead-shaped. They dry up without cracking when mature. They are often hung on treetops and do not fall through the winter. The seed weight is 125 grams, about 8,000 seeds per kilogram, and the germination rate is 70-85%. The germination ability of seeds stored dry can be maintained for more than 2-3 years. Variations: (1) Sophora japonica: The branchlets are curved and drooping, the crown is umbrella-shaped, and it is often planted in gardens. (2) Sophora japonica: 15-17 leaflets, the leaves are covered with blue-gray filamentous pubescence; the wing petals and keel petals of the flower are often purple, and the flowering period is the latest. (3) Sophora japonica: leaflets are clustered with 3-5 leaves, the terminal leaflets are often 3-lobed, and the lower parts of the lateral leaflets often have large lobes. The growth habit is cold-tolerant, prefers sunshine, slightly shade-tolerant, intolerant of dampness and drought, grows poorly in low-lying water areas, has deep roots, is not strict with soil, and is more tolerant of barren, lime and mildly saline-alkali soil (salt content 0.15 About %) can also grow normally. 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. 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. It is also a windproof and sand-fixing tree species that can be used as both timber and economic forest. It is a good shade tree and street tree species in urban and rural areas. Sophora japonica is one of the traditional tree species for garden greening in China and is full of national sentiment. The leaves of Sophora quinata are uniquely shaped, like thousands of green butterflies perched on the tree. It is a wonder and should be planted alone. Propagation and cultivation: Mainly sowing and propagating, but also cuttings can 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. This species is a poisonous plant included in the Chinese Plant Atlas Database. Its toxicity is to the flowers, leaves, stem bark and pods. Poisoning by eating piranha flowers and leaves may cause facial swelling, skin heat, and itching. The leaves and pods can also irritate the gastrointestinal mucosa, causing colic and diarrhea. Nut shell extract can cause breathing difficulties in mice and rats. Sophora japonica is cool in nature and bitter in taste, and 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 the normal resistance of capillaries, and prevent bleeding, hypertension, and diabetes caused by excessive capillary fragility and high permeability. Taking it can prevent bleeding.
