The brocade is commonly known as bougainvillea, bougainvillea, Maobao towel, and evergreen climbing shrubs. The flowers are small, three clusters, and there are three slices of leaves that are shaped like leaves but are bright and unusual. People often regard them as petals, hence the name bougainvillea. When the temperature is suitable, it can bloom all the year round. Bougainvillea will get this name because its pattern is rather peculiar, only three petals, and the shape of the three-petal petals is inverted triangle, so it is very different from other plums. Bougainvillea cultivation method: 1. Soil: Bougainvillea has poor requirements on soil, and it grows well in poorly drained and mineral-rich soils, which are poor, alkali-resistant, drought-tolerant and avoid water accumulation. The slightly acidic soil is most conducive to the growth of bougainvillea. 2. Watering: Pay attention to controlling the amount of water before flowering. The usual watering of bougainvillea masters the principle of “do not dry or pour, but pass throughâ€. However, to make the bougainvillea flower neat and flowery, water control must be carried out before flowering. Starting from September, the watering of the bougainvillea is controlled. Each time the watering is done, the potting soil is dry and the branches and leaves are softly hanged. This is repeated for half a month, and after half a month, it is normal to water. Do not apply fertilizer during water control to prevent the fertilizer from burning roots. In about a month, the bougainvillea blooms and the flowers are open and tidy. 3. Temperature: The suitable temperature for growth is 15-30 °C. In summer, it should be properly shaded or sprayed, ventilated, etc., and the temperature should be maintained at no less than 5 °C in winter, otherwise it will be susceptible to frozen leaves. Flowering requires a temperature above 15 °C. In order to prolong the flowering period, it should be moved into the room in time before the cold current in early winter, and placed in a sunny place to maintain a high ambient temperature (continuous flowering on New Year's Day and Spring Festival). 4. Fertilization: Fertilization cannot come, nor can it be too little. In order to make the bougainvillea bloom more, it is necessary to ensure sufficient nutrients, and at the same time, fertilization should be timely and appropriate, and rational use. Generally, from April to July, the growth period is high, and the liquid fertilizer is applied every 7 to 10 days to promote the growth of the plant. The fertilizer can be used with 10% to 20% of decomposed bean cake, rapeseed cake water or human waste water. 5. Illumination and ventilation: The bougainvillea is a positive plant. In order to make the branches and leaves grow normally and increase the number of flowering, the bougainvillea must be placed in a well-lit, well-ventilated place, allowing it to light for 8 hours to 12 hours a day. If the placement is often shaded, the plants will grow and the number of flowers will be reduced. If the placement position is not ventilated or the basin and the basin are placed too densely, the leaves will fall off, especially in hot summer, and the heat will suddenly fall off, which will easily cause large areas of leaves to fall off, thus affecting the growth and flowering of the plants. 7. Trimming: Trimming is exquisite, not too casual. Bougainvillea grows rapidly, and it is necessary to pay attention to plastic trimming during the growing season to promote the growth of side branches and more flowering branches. The number of pruning is generally 1 to 3 times, and it should not be too much, otherwise it will affect the number of flowering. After each flowering, it is necessary to remove residual flowers in time to reduce nutrient consumption. After the flowering period, the dense branches, inner lychee, long branches, and weak branches should be thinned. For other branches, the branches are generally not trimmed or only the branches are slightly trimmed. It is not suitable to be cut again to shorten the growth period of the next round. It blooms early and blooms many times. 8. Pest control: The common pests of bougainvillea mainly include leaf beetles and aphids, and common diseases mainly include blight. It is necessary to strengthen the weeding of loose soil, remove dead branches and diseased leaves in time, and pay attention to ventilation to reduce the spread of the source of the disease. Strengthen the examination of the condition and find out that the condition is treated in time, and it can be controlled with solutions such as dimethoate and thiophanate. 9. Loosening and changing pots: This can't be lazy. Due to long-term watering, fertilization and rain erosion, the bougainvillea is easy to compact. Therefore, it is necessary to loosen the soil regularly and remove the weeds in the pots to facilitate the growth of the bougainvillea. Otherwise, the soil of the potting soil and water accumulation may easily cause the roots of the bougainvillea to rot or grow poorly. In addition, the growth of bougainvillea is faster, the root system is developed, and there are many roots. It needs to be changed once a year. Bougainvillea breeding method: (1) Cutting propagation method: The propagation of bougainvillea is mainly cutting, and the survival rate of cuttings is high in summer. The annual semi-lignified branches should be selected for cutting, cut into 10~15cm segments, inserted in sand bed, at 20~25°C, 20-25 days. It can be rooted, and it can be bloomed after 40 days. If hormone treatment is used before cutting, it can promote rooting and increase survival rate. (2) bead propagation method: The bead can be used in the ordinary beading method, mostly in the spring and autumn, the bead can be scratched first, then buried in the soil, keep the temperature above 20 °C, roots can be rooted in about 20 days, and cut off from the mother after autumn.
