Life Habits Sophora japonica likes light, is cold-resistant, low temperature of minus 33 degrees, drought-resistant, barren-resistant, saline-alkali-resistant, capable of absorbing sound, with few pests and diseases, strong disease resistance, developed root system, strong germination and tillering ability and strong soil and water conservation ability.

After several years' trial planting identification by Chinese Academy of Forestry, Sophora japonica is cold-resistant, heat-resistant, drought-resistant, ridged and fast-growing. It blooms in two years and reaches its peak in three years. Sophora japonica south of the Yellow River blooms three times a year for 20 to 40 days each time. In the south of the Yangtze River, Sophora japonica blooms four times a year or in multiple seasons, each flowering period is 20 to 40 days. In the northeast and north China, Sophora japonica blooms twice a year, in May (flowering period is 20 days) and July (flowering period is 40 days) respectively, which is a rare tree species suitable for urban landscaping in China.

Sophora japonica is easy to propagate, and it is preferred to bury roots, cut and graft. Fast growth: the annual seedling is 2 meters high, the biennial seedling is about 3 meters high, DBH is 2-3 cm, and it begins to bloom; The survival rate of transplanting is over 95%, and the transplanting of seedlings does not need soil, which is convenient for long-distance transportation.

Morphological characteristics: fast growth, early flowering, multi-season flowering: Sophora japonica can grow to 2? 3 meters, two years, the tree energy is as high as 3? 4 meters, DBH can reach about 3 cm. When planting trees, it began to blossom in two years and flourished in three years. In the northeast, they bloom twice a year in May and July, three times in the south of the Yellow River and continuously in spring, summer and autumn in the south of the Yangtze River.

Sophora japonica is transplanted in spring and blooms that year, which is an excellent nectar source tree species. It has thick branches and leaves, the petiole is not easy to fall off, the root system is developed, the main lateral roots are strong, the tillering is fast, it can effectively prevent wind and maintain water and soil, and it is cold-resistant, drought-resistant, high-temperature resistant and pest-resistant. Sophora japonica grows fast, can be buried in roots or propagated by cutting, and its trunk diameter is more than 3.5 cm, so it is an optional tree species for developing wind and sand fixation in western China.

The distribution range originated in Spain and was introduced to North Korea in 1960s. Sophora japonica grows well in the south, north and northwest of China. In addition to being widely planted in the local area, it will be planted in Beijing in large quantities to create a strong green Olympic atmosphere.

Planting techniques should be transplanted after defoliation in autumn or before germination in spring. After planting, water it in time, and then water it about 3 times according to the drought situation to ensure survival. Sophora japonica has strong vitality. The survival rate of planting is high, and the transplanted seedlings do not need soil or chemical treatment. In order to make the seedlings grow strong, after transplanting, level the stubble on the ground, cut off thousands of branches on the ground, and leave a strong bud from the base. After stubble leveling, Sophora japonica not only has high survival rate, but also has good tree shape and fast growth. Sophora japonica grows naturally, with an open crown and beautiful tree shape, and does not need pruning. The height of the tree in the year of planting can reach 2? 3m, the taproot and lateral root are 2m long, and generally bloom in the second year after planting.

Sophora japonica is a small deciduous tree in Leguminosae, with a height of 6-8 meters and a brown to grayish brown trunk. Leaves alternate, dark green and shiny, green and green. These flowers are pink and have a strong fragrance. It blooms twice a year, the first time in mid-May and the second time in August. The flowering period is about 60 days and the flower diameter is 4-7 cm. When flowers bloom, clusters of flowers gather on the branches. Sophora japonica likes warm and humid climate and sunny and well-ventilated environment; For soil requirements, neutral soil with moist, good drainage and deep and loose soil layer is better, and acidic and alkaline soil can also adapt. Sophora japonica is cold-resistant and drought-resistant, and can resist -25? At the low temperature of -30℃, it can be cultivated in the open field in the north, and it is a rare cold-resistant landscaping tree species.

The propagation of Sophora japonica generally adopts the methods of burying roots and pruning, but burying roots is the main method. The main roots and lateral roots of Sophora japonica with a diameter of 0.5- 1-2 years were selected for root burying propagation. In spring, before Sophora japonica sprouts, the lateral roots should be cut off by 20-30 cm, and the amount of root cutting should not exceed half of the lateral roots, so as not to affect the normal growth and flowering of the plants. Dig out the cut root to avoid damaging the root bark. Before cutting, you can use sand or bury soil to prevent dehydration. Take out the roots in mid-April, cut them into 8- 10 cm cuttings, and bury the cuttings in the bed with a depth of about 5 cm and a row spacing of 20 cm? 30 centimeters. One-year-old stiff branches were selected as cutting methods. In the middle of April in spring, cut the branches into cuttings of 10- 12 cm. Every 50 plants are 1 bundle, and the roots are soaked with 50mg/L ABT2 rooting powder for 2-4 hours, and then the cuttings can be taken out and drained. Spread a plastic film on the edge to increase the temperature and humidity. Insert the cuttings into the bed at a 45-degree angle, with a row spacing of 20 cm? 20 centimeters. After cutting, the soil is often kept moist, and the cutting seedlings can grow to 1- 1.5 meters high in the same year. Sophora japonica can reproduce quickly, and each finished seedling can reproduce 30-40 plants by root cutting in the second year.

The transplanting of Sophora japonica should be carried out after defoliation in autumn or before germination in spring. When planting, dig holes and apply sufficient base fertilizer. After planting, fill the soil, compact it, water it, and then keep it moist. Because Sophora japonica has strong vitality and high planting survival rate, seedlings do not need to carry soil, and the planting survival rate can reach over 98%. After planting, according to different greening environments, the stem should be fixed at 0.8- 1.5m to promote branching. Sophora japonica grows fast and blooms early, usually in the second year after planting. In the year of planting, the height of the tree can reach 3-4m, and the DBH is 4-5cm. According to different green attraction, natural growth or spherical pruning can be adopted.

The most ornamental value of Sophora japonica is the red flower, which can bloom 200-500 red flowers at the same time, which is very spectacular and beautiful. The most valuable cultivation is that flowers bloom in two seasons a year, which can be described as "enjoying beautiful scenery in the garden in early autumn, and Sophora japonica blooms in different colors". The most valuable for popularization is cold resistance and drought resistance, which is adaptable to both north and south. Sophora japonica is a new woody flower variety that needs to be developed urgently because of its unique ornamental and landscaping value.

The main value of Sophora japonica is high-quality fast-growing wood, branches, leaves and roots are fuels, tender leaves are feed and green manure, and flowers are excellent honey sources and food, all of which are treasures. The most attractive ornamental value of Sophora japonica is that the red flowers and green leaves are full of beautiful trees, and the flowers are fragrant in the north and in the south all year round; The most satisfactory cultivation value is that it is widely used, purified and ornamental, and green and beautified. The most popular values are cold tolerance, drought tolerance, heat tolerance and strong adaptability, which can be planted in both north and south, and everything can be planted. As the new favorite of greening and beautification in China, Sophora japonica has a very broad development prospect. After several years' introduction of many kinds of garden greening experimental varieties, Sophora japonica has the best performance and response in different regions and environments. On September 6th, 20001year, this tree species was positioned by China Academy of Forestry as a high-grade excellent new tree species for landscaping, and was also listed as an excellent new tree species for the greening of Olympic-related track sections by Beijing Garden Department. In a word, the introduction time of Sophora japonica is short, the introduction quantity is small and the scale is small. At present, it is in the stage of seedling propagation, and the development scale in all parts of the country is small, lacking large-scale green seedlings. It is a new variety of woody flowers for landscaping that needs to be expanded urgently at this stage, and it has great development space in the next decade.

The flower language of plant culture is crystal clear, beautiful and refined, and is deeply loved by spring.
