Bougainvillea cultivation techniques

Bougainvillea is also known as bougainvillea and treasure towel. It has more than 100 kinds of species. It has wide adaptability, strong vitality, and can enjoy all kinds of flowers. It also has rich colors, long flowering period and flowering. It is a very good potted flower. It is also used in landscape gardens for hedgerows, porches, and bonsai. As long as the varieties are right and properly managed, they can grow and bloom throughout the year.

Habits: Bougainvillea is a tropical plant, hi temperature and humidity environment, but also more resistant to dry heat, drought, cold intolerance, avoid frost temperature in winter not less than 3-7 °C. The optimum temperature for growth was 15°C, and the optimum temperature for flowering was 15-30°C. Bougainvillea is a yang plant, which requires sufficient light and plenty of light. Strict requirements on the soil, resistance to thin drought, avoid water, the most suitable for loose fertile sandy loam.

Breeding: Using cutting method, greenhouse cuttings can be in January-March, and select mature branches to be inserted into the sand bed. Rooting at room temperature below 25°C for about 1 month. If the open field cuttings can be carried out after the flowers. Treatment with 20 mg/L IBA for 24 hours promoted the rooting of the cuttings. For cuttings that are not easy to root, they can be bred by the grafting method or air-ballasting method.

Management: During the cultivation process, it should be frequently picked up to form a clustered and low plant shape. Can also be set up to climb up. The bougainvillea is a light plant, and it should be placed or cultivated in a sunny place whether it is indoors or in open fields. Before spring sprouting, change the basin, water in summer and flowering time, and reduce the amount of watering after flowering. Daily watering is based on the principle of “dry between the stem and the stem”. During the period of slow growth, 1 fertilization is applied. In the vigorous growth period, 1 fertilization is applied in half a month. Phosphate fertilizer is applied several times during flowering. During the flowering period, there are more flowers and fallen leaves. Clean up in time to keep the plants clean and beautiful. After flowering, the pruning is performed to adjust the tree vigor, and the dead branches, the dense branches, the sick and the weak branches and the branch shoots are cut off, and more robust new branches are promoted to ensure flowering bloom. About 5 years can be re-cut 1 update. To control the watering in winter to make the plants fully dormant, flowering in spring and summer will be more colorful.

Most products of Fluorine-containing Benzonitrile is a colorless transparent liquid and has a pungent odor. It was widely used in pesticides, pharmaceuticals liquid crystal material manufacturing. High efficiency, low toxicity and residue characteristics. Through extensive research and production practice, we have found some good manufacturing processes of fluoro-containing cyanophenyl products. In addition, we have groundbreaking research on ratio of raw materials, solvent selection, the choice of solvent concentration, related use of catalysts..
