Ordinary and simple bougainvillea can be seen everywhere in this city. Bougainvillea is a tropical plant, which likes warm and humid climate and is not cold-resistant. Below I will introduce the cultivation methods and precautions of bougainvillea for everyone. Welcome to reading.

Cultivation method of triangular plum blossom: soil

Bougainvillea is not strict with soil, and grows well in clay with good drainage and rich minerals. It is barren, alkali-resistant, drought-resistant and avoids water accumulation. Slightly acidic soil is most beneficial to the growth of bougainvillea.

Cultivation method of triangular plum blossom: watering

Water once a day in spring and autumn, once in the morning and evening in summer, once in the morning and evening after the emergence of watering buds in winter, and spray water on the leaves 1-2 times at the same time. In the rainy season, water should be prevented to prevent plants from rotting and dying.

Cultivation method of bougainvillea: temperature

The optimum growth temperature is 15-30℃, and measures such as shading, spraying water and ventilation should be taken in summer, and the ambient temperature should be kept not lower than 5℃ in winter.

Cultivation method of triangular plum blossom: fertilization

In addition to applying sufficient base fertilizer in the basin soil, topdressing should also be carried out in the growing season. Add a small amount of potassium dihydrogen phosphate and spray 0. 1%-0.2% potassium dihydrogen phosphate solution on the leaves. During the full flowering period, 1 times alum fertilizer is poured every week, and 0.2% potassium dihydrogen phosphate is sprayed on the leaves.

Cultivation method of bougainvillea: light

All the year round, except for the new seedlings in the pot, they should be placed in the semi-shade first. It should be placed in front of the south window in winter, and the illumination time should be no less than 8 hours.

Propagation method of bougainvillea: propagation

Selection of cutting branches: bougainvillea branches with thick arms and fine fragrance can be used for cutting; Thick branches take root late and form quickly; Annual lignified green branches are easy to grow new roots and have high survival rate. Generally, the 1-2-year-old outer-layer sun branches with compact and robust structure are selected, and * * * branches, immature branches, long branches and shaded branches are not used. * * * Cut into 3-4 sections with a sharp knife * * * The length is about 8- 10cm***. The lower slope is 5- 10 mm below the section. Remove the lower leaves and keep the upper two leaves as cuttings.

Cultivation method of bougainvillea: pruning

Bougainvillea grows strongly, so it needs pruning every year. Bougainvillea is usually propagated by cutting, which makes it easy to raise seedlings. In May and June, the mature lignified branches were cut into 20cm long, inserted into a sand basin, covered with glass and kept moist. They can take root in a month or so and blossom in two years. Pruning method: after flowering, moderate pruning, cut off pedicels, retract the branches of13, and sparse weak branches, short branches and internal branches. Pruning should be short, heavy and sparse in combination with soil replacement in winter. Short, short-cut, branches with 1/3 reserved; Heavy, used to cut long branches; Thinning refers to thinning weak branches to make them grow strong branches again, which is also called renewal pruning. The cut branches can be reserved for cutting seedlings. Bougainvillea bougainvillea is planted in the south as a flower stand, fence and doorway. In winter, bougainvillea doesn't rest or shed leaves, but it is only lightly cut, but it should be tied, distributed and pulled so that the flower branches can stand evenly, be distributed reasonably and be covered with flowers.

Matters needing attention in bougainvillea cultivation 1 Pay attention to lighting and ventilation.

Bougainvillea is a positive plant. In order to make the branches and leaves grow normally and increase the number of flowers, bougainvillea must be placed in a well-lit and well-ventilated place, and let it shine for 8 hours to 12 hours every day. If the place is often blocked, plants will grow in vain and the number of flowers will be reduced. If the place is not ventilated or the flowerpots are placed too densely, the leaves will fall off, especially in hot summer, when it is hot and rainy, it is easy to cause the leaves to fall off in a large area, thus affecting the growth and flowering of plants.

2. Strengthen pest control

The common pests of bougainvillea mainly include leaf beetle and aphid, and the common diseases mainly include shoot blight. At ordinary times, we should strengthen loosening soil and weeding, remove dead branches and diseased leaves in time, pay attention to ventilation, and reduce the spread of disease sources. Strengthen the examination of the disease, and if it is found and treated in time, it can be prevented and treated with dimethoate, Tobuzin and other solutions.

In love, the flower language of bougainvillea means empathy. There is another flower language: enthusiasm, perseverance and indomitable spirit.

Continuous flowering method of bougainvillea 1, water control and flower cultivation: bougainvillea likes strong light and high temperature, is not afraid of sun exposure, requires little water, and the basin soil needs to be kept moist. We must control the water 1 month in autumn and winter, and keep it semi-dry and semi-wet, even if the green leaves wither. Controlling water is beneficial to the growth of flowers, which is also the reason why domestic bougainvillea "does not bloom frequently, but is lazy to spend constantly".

2, pruning rejuvenation needs water control: bougainvillea is strong, has strong germination, and is particularly resistant to pruning. Regular pruning and shaping can make its branches more beautiful. It should be reminded that it has a special habit of sprouting first and then taking root. Don't water the old potted plants immediately, but water them once every two days. Moisturize moderately in the future, and gradually turn to normal watering after the new shoots basically grow out, and place them in the sunny place with a temperature of about 25 degrees Celsius.

3, winter warm water control: bougainvillea likes warmth, not cold-resistant, avoid waterlogging, winter must pay attention to warm water control. Keep the temperature above 7 degrees Celsius in winter, or you will freeze to death. Once the temperature drops sharply, plants will lose many leaves, so don't water them too much. It should be placed in the environment of 10℃ to 15℃, and watered once every 10 days, and then gradually increase the watering amount after budding and leaf emergence in spring. Otherwise, it will lead to the death of rotten roots.

Fertilization method of bougainvillea cultivation bougainvillea likes fertilization. After the weather gets warmer in spring, nitrogen fertilizer 1 time every/kloc-0 ~ 1 5 days, cake fertilizer1time every week during the growing period, and phosphorus fertilizer several times during the flowering period. Reduce the amount of fertilization after cooling in autumn and stop fertilization in winter. At the peak of growth and flowering, the potassium dihydrogen phosphate solution with the ratio of 1000 can be sprayed on the leaves for 2 ~ 3 times, or the "Huaduoduo" general fertilizer with the ratio of 1000 can be topdressing every10 day.

Stop fertilizing when the temperature is cool in autumn. Do not apply fertilizer when the temperature is low in late autumn, winter and early spring. However, if the temperature is above 15℃, the mixed liquid fertilizer can be applied every other month 1 time.

Bougainvillea is very sensitive to urea, and if it is not properly fertilized, it may lead to the phenomenon that leaves are flourishing and flowers are few, so it is necessary to be particularly cautious when applying urea.

Spring is the vegetative growth period of bougainvillea, and urea can be applied once per kloc-0/week. This can not only supplement the consumption of plants after flowering, but also promote the growth of new branches and lay a good foundation for reproductive growth.

Dilute liquid fertilizer should be applied in summer, and 0.2% ~ 0.3% potassium dihydrogen phosphate solution can be used as foliar topdressing when conditions permit, every half month 1 time. At the initial stage of flower branch growth, it is still necessary to apply 1 times urea to facilitate flower branch growth.

The cultivation and propagation method of bougainvillea bougainvillea mainly adopts cutting propagation, and for varieties that are not easy to take root by cutting, grafting or high pressure propagation can be adopted.

Cutting propagation: generally, after flowering in June-July, cut off the mature semi-lignified branches with the length of 65,438+00 ~ 65,438+05 cm, soak the cutting base with 20 mg/kg of indolebutyric acid for "hours", and then insert it into a sand bed or a spray seedbed. At the temperature of 2L ~ 25℃ and the relative humidity of 80% ~ 90%, 65. It can also be cut in greenhouse 65438 from June to March.
