The production of Huangqi bonsai

Huangqi, also known as red leaves, is a deciduous shrub of the family Lacqueraceae. In recent years, the Beijing Bonsai Association has adopted Huang Yu tree species to produce various forms of tree stump bonsai, which is favored by the majority of bonsai lovers. Using it to make bonsai has the characteristics of simplicity and vitality and rich in variety. Spring buds early shade, green gratifying, midsummer branches and leaves in full bloom, golden autumn red leaves first dyed, after frost full of red leaves, proud frost erect, dazzling, frequently add a little autumn color, endless charm, beautiful. There are many wild resources of Phellodendron chinense in Beijing area, which is easy to be collected. Therefore, the production of Huangqi bonsai is mainly based on field excavation. The time of excavation should be before the sprouting of early spring (March) or in the late autumn season. The stumps dug back from the wild should be initially trimmed and reshaped. Cut the overly long taproot short and retain as many lateral roots as possible to facilitate the absorption of water and nutrients. Cut off the dense branches and shrink the overgrown branches on the trunk. Then plant on the ground or in the air, pour water once after planting, and then keep the potted soil often moist, and often spray water on the branches to facilitate survival. Creating a moist environment with weak light is conducive to the germination and growth of new buds. After the leaf buds of the plant elongate, gradually increase the light and watering, combined with watering, you can apply an appropriate amount of dilute liquid fertilizer to promote the vigorous growth of the tree. usually, the stump can be sham-planted for a year. According to its characteristics, it can be made into oblique dry type, horizontal dry type, cliff type and other bonsai. The shape of Huangqi bonsai should vary from material to material, giving full play to its strengths and avoiding its weaknesses. The modeling method mostly adopts the method of "coarse binding and fine cutting", but the specific modeling should be tailored to the conditions of the students. For example, if the stump with thicker trunk has poor bending performance and is not easy to bend and climb, the method of cutting dry livestock branches can be adopted to cut off the top of the curved part of the trunk, cultivate new branches, and gradually trim livestock branches to cultivate a beautiful tree shape. For the shape of the small stump, the method of cutting and pruning is often used, that is, the trunk and part of the branches are made of metal wire or nylon wire, and then pruned according to the modeling needs, so as to cultivate a hierarchical and graceful tree posture. In short, styling and pruning should be based on the natural conditions of the plant and conform to nature in order to save time and achieve ideal artistic results. Huang likes the sun, but he can grow well in places where there is not enough light. Daily watering is appropriate to keep the wet and dry between the basin and soil. Fertilization can apply fermented cake fertilizer and water in spring and autumn every year to promote its growth and health. Plants grow vigorously in spring and summer, so they should be pruned frequently. Pruning for overgrown, endophytic and over-dense branches. Keep the tree shape beautiful, improve the ventilation and light transmission conditions, and reduce the occurrence of diseases and insect pests. Huangqi bonsai in late autumn, will show bright red leaves, ornamental effect is the best. In order to make the leaves of bonsai turn red and become a good ornamental in autumn, it is particularly important to strengthen the management in autumn. Watering in autumn is appropriate to keep the basin soil moist. In order to make the leaves green and red, apply rarefied liquid fertilizer every ten days or so. At this time, bonsai should be placed in a place with sufficient light and good ventilation, and let it accept more dew at night, which is very beneficial to the redness of the leaves.
