The flowering period of leaves is longer and the flowers are more beautiful. In the south, the general flowering period is from October of the year to the beginning of June of the following year. How to make potted leaves bloom more? The author believes that the following aspects must be done: First, the choice of culture soil The leaf flower does not require strict soil, but it is afraid of stagnant water and impatience. Therefore, loose soil and well-drained culture soil must be selected. Generally, 4 soils of humus, 4 soils, 2 sands can be used, and some dried coal can be used to add some coal cake residue to the pot soil. Second, reasonable fertilization to make leaves bloom more, we must ensure adequate nutrients, while timely and appropriate amount of fertilization, the rational use. Generally from April to July, the growth period is prosperous. Liquid fertilizer is applied once every 7 days to 10 days to promote healthy growth. Fertilizer can use 10% to 20% cooked bean cake, rapeseed cake water or human feces water. Starting in August, in order to promote the gestation of flower buds, fertilizers dominated by phosphate fertilizers are applied. Fertilizers are applied once every 10 days, and 20% of rotten chickens and ducks can be used for droppings and fish liquids. Since the flowering period began in October, from this time to mid-November, fertilizers based on phosphate fertilizers are applied once every two weeks. The concentration of fertilizers is 30% to 40%. Every time after flowering, topdressing should be applied once again, so that the leaves of flowers are continuously supplemented with nutrients during flowering. Third, to control the water before flowering, the usual watering of bougainvillea grasp "do not do not poured, pouring will be thorough" principle. However, to make the leaves flower neat and flowery, water must be controlled before flowering. From September, the watering of the bougainvillea was controlled. Each time the watering was done, it was necessary to wait until the pelvic soil was dry and the branches and leaves were sloppy. After repeated half a month, the normal watering was resumed after half a month. Avoid fertilization during water control, so as not to burn the roots of the fertilizer. In this way, about one month later, the flowers of the leaves can bloom and the flowers bloom neatly and prosperously. Fourth, loose soil weeding and change leaves bonsai flowers due to long-term watering, fertilization and rain erosion, basin soil is easy to compact, so we must regularly loosen the soil, while removing the pot soil weeds, in order to facilitate the growth of the leaves. Otherwise, potted soil, water, easily lead to rot or poor growth of leaf flower roots. In addition, the leaves grow faster, the root system is developed, and there are many fibrous roots. Fifth, pruning leaves the flower to grow quickly, the growth period should pay attention to plastic pruning to promote lateral branch growth, more flowering branches. The number of prunings is usually from 1 to 3 times, and should not be excessive, otherwise it will affect the number of flowering. After each flowering, we must promptly remove residual flowers to reduce nutrient consumption. After the flowering period, the dense branches, inner litchi, leggy branches and weak branches shall be thinned. For other branches, the branches must not be trimmed or the branches must be trimmed. It is not appropriate to cut them again to shorten the growth period of the next round and promote It blooms early and blossoms many times. Pay attention to the light and ventilation The bougainvillea is a positive plant. In order for the normal growth of the leaves and the increase of flowering times, the bougainvillea must be placed in a well-lit and well-ventilated place and let it light for 8 to 12 hours per day. If the placement is often shaded, the plants will grow longer and the number of flowers will decrease. If the place is not ventilated or placed too densely between the basin and the basin, leaves will fall off, especially in hot summer, hot and cold, it will easily cause large areas of leaves to fall off, thus affecting plant growth and flowering. VII. Strengthen Pest Control The common pests of leaf flowers are leaf aphids and aphids. Common diseases mainly include blight disease. Usually we must strengthen weeding and weed control, timely removal of dead branches and diseased leaves, and pay attention to ventilation to reduce the spread of the disease. Strengthen the examination of the condition and find out the condition in time. It can be treated with dimethoate, thiophanate and other solutions.
