Bougainvillea, with its special petals, has attracted many planting users. We have interviewed the relevant technical staff of the Forestry Bureau of our county for the management of the management of Bougainvillea, and are summarized as follows for reference.

First, the growth temperature

The optimum growth temperature is 15-30 degrees Celsius, which is 19-30 degrees Celsius in May-September, 13-16 degrees Celsius in October-April year, 35 degrees Celsius high temperature in summer, over 35 degrees Celsius, it should be properly covered Shade or take water spray, ventilation and other measures, the winter should maintain an ambient temperature of not less than 5 degrees Celsius, otherwise long-term temperature below 5 degrees Celsius, susceptible to frozen leaves.

Triangle flowering needs 15 degrees Celsius or more. In order to prolong the flowering period, it should be moved into the room immediately before the arrival of the cold spell in early winter. It should be placed in a sunny place and maintain a high ambient temperature (it can bloom on New Year's Day and Spring Festival).

Second, light time

Triangle flowers like light, is a positive flower, lack of light during the growing season will lead to plant growth weakness, affecting buds and flowering, therefore, in addition to the new seedlings all year round should be placed at half shade. Winter should be placed in front of the south window, and the lighting time can not be less than 8 hours, otherwise it is prone to a large number of fallen leaves. Short-day flowers, the daily light time is controlled at about 9 hours, and it can blossom after one and a half months.

Third, moisture supply

The spring and autumn seasons should be watered once a day. In the summer, water can be poured every morning and evening. In winter, the temperature is low and the plants are in a dormant state. Watering should be controlled to keep the basin soil moist. The proper control of water in the growing season of potted plants can promote the differentiation of flower buds; the triangle flower is in a vigorous growth stage from June to July, and can appropriately control the water 2-3 times according to different species (degree to young shoots and new leaf shoots are wilting as Degree), spraying water to the leaves 1-2 times a day, 2-3 days before pouring water (to the pelvic floor water flow) This repeated control of water several times, can effectively promote flower bud differentiation, watering every morning and evening after the emergence of buds Once, spray water at the same time 1-2 times, until flowering, not standing water, the rainy season to prevent water accumulation in order to avoid the death of plant roots.

Fourth, the soil configuration

Triangular flowers like loose and fertile slightly acidic soil, avoid blisters, potted plants can be used to leaf soil, peat soil, sand, garden soil, and add a small amount of cooked cake residue as base fertilizer, mixed formulated as culture soil. Flowering plants are changed once a year in pots, and the time is better before germination in early spring. Scissors are used to cut over dense and aged branches.

Fifth, fertilization method

In addition to applying base fertilizer in potting soil, the growing season should also be topdressing. With the change of pots, according to the size of the plant, apply 10-15 cakes of fertilizer to each pot, and then top-up one thin cake of fertilizer and water every half month, and add 0.1% of potassium dihydrogen phosphate, which can accelerate its vegetative growth. It can promote the differentiation of flower buds. After budding, the fertilizer can be changed to phosphorus and potash fertilizers, and a small amount of potassium dihydrogen phosphate can be added to the thin cake fertilizer. At the same time, 0.2-0.2% of dihydrogen phosphate is sprayed on the leaves. Potassium solution was sprayed once a week in the flowering stage, and 0.2% potassium dihydrogen phosphate was sprayed on the leaves.

note:

1. In summer and winter due to slow or dormant plants, fertilization should be stopped to avoid causing damage.

2. Do not apply concentrated fertilizer or raw fertilizer (without adequately decomposed organic fertilizer) to prevent root damage, resulting in leaf coke shedding or even death of the whole plant.
