Key points of cultivation and Management of Bauhinia

Bauhinia has a wide range of distribution in China, mainly concentrated in Jiangsu, Beijing, Shandong and other provinces. The flowers of Bauhinia are very bright and glossy, so they have high ornamental value. And the bark, wood, flowers and fruits of Bauhinia can be used as medicine, so there is also a very large artificial planting area. However, when we are planting, we have to do a good job in field management in order to ensure the healthy growth of Bauhinia, so the editor below will introduce the field management technology of Bauhinia.

1. Water management

Water is very important for the growth of Bauhinia. It should be watered immediately after planting, especially in the early stage of planting. It must be watered at least three times in the first seven days to meet the water demand of Bauhinia. When we are watering, we should control the watering frequency and dosage according to the weather changes, such as timely watering in summer, but the moisture should not be too much, and we should pay attention to drainage after rain. If the temperature is not high in autumn, it is necessary to control the amount of water to prevent autumn, and then to pour anti-freezing water to enhance the cold resistance of Bauhinia. The spring of the following year should be watered in time during the period of returning to green. From April to October every year, except for watering according to precipitation at 7-8 o'clock, it should be watered once a month.

2. Proper topdressing

The growth of Bauhinia has a great demand for nutrition. Under the condition of sufficient nutrition, it can ensure the robust growth of Bauhinia, increase the number of branches and leaves, and enhance the glossiness of flowers. On the contrary, it will lead to lack of branches and leaves and dull flowers. Therefore, we should apply sufficient base fertilizer before planting, which is mainly based on fully mature farm manure, which should be fully mixed with the soil to prevent root burns caused by excessive heat emission. After normal growth, nitrogen fertilizer should be applied properly after flowering to enhance the growth of Bauhinia, and then phosphorus and potassium fertilizer should be applied in early autumn to promote flower bud differentiation. And when pouring anti-freezing water in early winter, farm manure should be applied once, and then foliar fertilizer should be properly sprayed according to plant growth to fully meet the nutrients needed for the growth of bauhinia.

3. Shaping and pruning

Under the condition of normal growth of Bauhinia, the branches and leaves of Bauhinia plants are luxuriant, if not pruned in time, it will lead to complex branch growth, reduce permeability and hinder the growth of Bauhinia. Especially when Bauhinia is used as an ornamental in various gardens, it is necessary to do a good pruning work in its young tree stage to promote the formation of a good plant type and enhance the ornamental value. After transplanting, it should be truncated properly to promote the growth of branches, increase the area of nutrient absorption and ensure sufficient nutrient accumulation. Then, in the spring of the following year, it was heavily truncated to promote the germination of new branches, and about three strong growing branches were retained to cut off the excess branches. Then remove the excess sprouting in time, pick the heart properly and promote the secondary branch.

4. Other management

The light demand of Bauhinia is relatively large, so when planting, we should pay attention to meet the light demand of Bauhinia, enhance the photosynthetic capacity of Bauhinia, improve the accumulation of nutrients, and increase the ornamental value of Bauhinia. However, attention should be paid to avoid direct sunlight for too long, otherwise it is easy to produce bad phenomena such as high temperature heat injury, burning leaves and so on. Therefore, we should not only ensure the light, but also shade properly. Finally, it is necessary to do a good job in clearing the garden in winter, the germs will overwinter in the sick and disabled bodies, soil and weeds, and harm the bauhinia in the spring of the following year, resulting in diseases and insect pests. Clearing the garden in winter can effectively reduce the base of pathogens and reduce the incidence of disease.

The above is a brief introduction to the key points of bauhinia cultivation and management. When pruning bauhinia trees, we should pay attention to the renewal of flowering branches of bauhinia. Generally more than 5 years of flowering branches, its flowering quantity will be greatly reduced, and flowering position upward, seriously reduce the ornamental value, so it should be updated in time. That's all for today's introduction. This article is for reference only. I hope it can help you all.
