(a) Botanical knowledge

Is a hematoxylin, Bauhinia. Small deciduous trees, usually shrub-like, with dense branches and 2 to 3 meters high. The young bark is smooth and the old one is cracked. Leaves alternate, heart-shaped or suborbicular, entire, smooth and glabrous. In mid-April, flowering, the flower is a fake butterfly, purple, 5 to 8 clusters were born on the old branches, the first leaves open, full of flowers, bright and eye-catching, quite charismatic. Red and purple pods, mature in October. For good flowering tree species.

Attached species

1. Cercis chinensis, leafy, leathery, broadly ovate, abaxially pubescent. Flowers pink, pedicels pendulous, for hanging racemes, 4 to 10 cm long. Purple fruit, 6 to 10 cm long. Produced in western Hubei and Sichuan Three Gorges area.

2. Huangshan Bauhinia, also known as Zhezhi Bauhinia. Leaves nearly leathery, ovoid or heart-shaped, smooth and glabrous. The first leaves blossom and the flowers cluster on old branches. The follicles are thick and leathery and have no narrow wings along the abdomen. Fruit matures in October, reddish purple.

Produced in Anhui Huangshan, Zhejiang, Guangdong and other places. Bauhinia has a cultivar: white flower redbud pure white, clustered on old branches. The same as the original species. Bauhinia is widely distributed in China, North China, East China, Southwest China, South China and other regions. It is a gardening plant that is commonly cultivated in various gardens.

Hi light, more cold-resistant, hi fertile and well-drained soil, intolerant. Sturdy and strong, resistant to pruning.

(B) Materials and Cultivation Measures

Artificial propagation: Sowing seedlings can be the main, but also ramets, layering. The sowing method was adopted in October to harvest seeds, and the dried fruits were dried and threshed. The sundries were removed and stored in bags. Seedlings are sown from February to March of the following year, soaked in warm water of 40°C for a day and night (naturally cooled) before sowing, and then soaked in fresh water and soaked for 4 to 5 days. Change the water once a day until the seeds are fully inflated and wrapped in wet gauze. The germination was carried out at room temperature of ~20°C. Seeds germinating after sowing, can promote rapid and neat germination. Seed bed soil to choose fertile loose sandy loam, drilling spacing 20 cm, sowing ditch depth 2 cm, after sowing covered fine soil thickness of about 1 cm, and then cover straw, with a fine hole watering pot watering. After about 2 weeks, the plantlets will emerge and the grass will be uncovered and shaded. Seedlings strengthen management, can promote seedlings robust growth. Leave the bed and cultivate it for 1 to 2 years. The propagation of tributaries should be carried out in October. The mother-branches of the tussock-like plants should be dug up and rooted. The roots should be tied up with a string, and the soil should be soiled and then re-planted. The spring of the year 2 to 3 Digging and planting in the month is also easy to survive. The bead propagation can be carried out in the spring growing season. The branches to be pressed into the soil are ring-skinned, deep to the xylem, pressed into the soil and covered with thick soil. General spring beading, cutting off from the mother in the autumn, and planting in the early spring.

Wild mountain digging: Wild Zijingensis are mostly born under the mountain mixed forest or in the ditch. It is possible to select old root piles with short stature and thick branches and branches. After the embryo culture, the roots will be restored and then transplanted into pots for processing.

(c) Upper basin process

Selection basins: Bauhinia generally use deeper glazed pots or zisha pots, which are more common in square, round and oval shapes, and sometimes use shallower rectangular pots. The color of the basin is preferably light yellow or cyan in order to reflect the purple flowers.

With soil: the soil quality requirements are not high, slightly acidic or slightly alkaline soil can adapt. Potted plants should be cultivated with fertile loose soil, good permeable leaf-leaf soil or pond river mud mixed with sandy soil and ash.

Planting: Usually planted between February and March in spring. When truncating the main root and the long root system, the branches should be cut properly, leaving only 3 to 4 years old branches as the backbone.

(four) the entire posture technology

Processing: Bauhinia adopts the processing modeling method mainly based on scissors and supplemented by bar. Generally, it is only necessary to properly tie the main stem to the required posture, and it is more convenient to use metal wire for climbing, and it is better to perform after the rainy season. The sculpturing of branches is carried out by pruning and climbing. It is also advisable to process the flowers after flowering.

Tree: Bauhinia bonsai shape is mainly oblique dry, curved dry, weeding, jungle and so on. Natural shape is also good, full of purple flowers, very beautiful.
