1, shape selection:

The modeling method of bougainvillea bonsai is mainly pruning, supplemented by plate binding. The manufacturing process is relatively easy. According to the different conditions of potted plants, in addition to the above forms, they can also be made into different shapes such as single knife, double knife, horizontal knife, flood and drought type, waterfront type, pagoda type, flower basket type and so on. Different growth stages of bougainvillea have different modeling requirements. For example, small trees can be tied according to the needs of modeling, and of course, bougainvillea with several different colors can be planted together for docking and combination according to different needs. Today, we mainly introduce the popular bougainvillea.

2. Production process:

(1) Planting and binding: firstly, 2-3 bougainvillea plants are planted together in a flowerpot, and the branch spacing is 3 cm. When the normally growing branches reach a suitable height (depending on the shape), tie them tightly with iron wire with plastic skin.

(2) docking of pine branches: after growing and forming, pine branches, cut off the skin at the joint of each branch with a knife, and dock with the cambium.

(3) Dismantle the tie line: tie it tightly after docking (but the wound should be watered against rain), and dismantle it in time after the tie line grows firmly and forms a whole.

(4) Plastic surgery: We regard the following part as the root. Generally, it can be bent according to your own needs to create various styles and shapes, or it can be matched with stones to form a boulder.

(5) Strengthen pruning: After the plastic surgery is completed, many branches will grow in the above-mentioned parts, which can be appropriately pruned according to the intention to subtract the redundant branches. It is worth noting that pruning must be carried out according to the overall image of the idea. Before pruning, we should know fairly well and not blindly.

(6) Bending and shaping: the remaining branches after pruning are further bent and shaped. As time goes on, the lower part will grow a new trunk, but its surface will be rough, but it will be more vigorous and simple. At this time, you can constantly trim the shape to achieve the purpose of simple roots, lush crown and rich level changes. In this way, a bonsai of bougainvillea with hanging roots and claws is made.

Second, the bougainvillea bonsai later maintenance management measures:

The maintenance method of bougainvillea may be clear to many basin friends, but the fine management of bougainvillea bonsai still needs to be done. Let me introduce how bougainvillea achieves fine management:

1, sufficient light:

Considering that bougainvillea is a plant that likes high temperature and long light, it must be placed in a sunny place. On the one hand, it can make it grow and develop rapidly, on the other hand, it can better carry out photosynthesis, which is beneficial to flower bud differentiation and timely supplement nutrition. As a senior bougainvillea breeder, I can tell you that bougainvillea after long sunshine is not only short and strong in internodes, but also has a large number of flowers, dark colors, long flowering period and fast forming.

2, proper watering:

Although bougainvillea likes warm and humid environment, it is very strict when watering this piece. Different growth periods and flowering periods require different amounts of water. As far as flowering period is concerned, the amount of watering began to decrease five weeks before flowering (that is, around mid-August). After watering once, wait for the leaves and buds to droop before watering. The reduced water quantity is affected by the slight moisture of the basin soil. Repeat this until the embryonic form of flowers appears between the branches and axils, and then gradually return to normal watering. This reduction of water not only increases the concentration of cell fluid, but also promotes the differentiation and formation of flower buds.

3. Rational fertilization:

(1) bougainvillea is particularly sensitive to urea, so we should be especially careful when applying urea. If the period and proportion of fertilization are not appropriate, it is likely that there will be fewer leaves and flowers.

(2) In summer, when the temperature is high and there is much rain, plants tend to grow white. At this time, urea can not be applied alone, but some fertilizer made of waste vegetables can be applied.

(3) If conditions permit, potassium dihydrogen phosphate mixed with water can be used as foliar topdressing once every half month.

(4) Urea should still be applied once in the early stage of flower growth, which is beneficial to the growth.

The above four measures, as long as you master the latter two, can completely avoid the adverse effects caused by insufficient sunshine.

4, timely pruning:

(1) Considering the long growth period and fast growth rate of bougainvillea, it is necessary to pick and prune the seeds in time to fix and maintain the plant shape.

(2) The flowers in bougainvillea bonsai only bloom at the top of the new branches, and coring is helpful to popularize the new technology and make it blossom more.

(3) Pruning is generally carried out in spring and summer. Pruning is not needed after mid-August, which will affect the later flowering.

(4) Pruning branches are generally inner branches, thin branches, long branches and cross branches. However, some long branches sometimes need to leave 1-2 buds for short cutting.

Third, how to promote flowers in bougainvillea bonsai:

(1) Adequate fertilizers must be provided at the flourishing stage, mainly nitrogen fertilizer.

(2) Topdressing phosphorus and potassium fertilizer at flowering stage was 65438 0 times.

(3) Bundled bougainvillea bougainvillea should not be fertilized too much, otherwise it will grow too fast and affect the tree type.
