Triangle plum scientific name light leaf flower, also known as three-leaf plum, Mao Baojin, azalea, triangle flower, etc., for purple glory family leaf flower belongs to rattan shrub plant, native to Brazil, south of our country planted in courtyard, park as ornamental plant, north cultivated in greenhouse, can also be used as bonsai, hedge and pruning modeling, below we will take a look at the cultivation method of triangle plum bar!

How much is the price of triangular plum?

The price of triangular plum is generally based on the height, crown width and viewing performance of triangular plum to price, generally in the diameter of 2 cm height in 200 cm crown width in 100 meters or so triangular plum about 100 yuan a tree, of course, generally like a small height in 30 cm crown width in 30 cm saplings generally in the price of 10~20 yuan a tree.

Cultivation Environment of Bougainvillea chinensis

Bougainvillea is a tropical plant, likes high temperature and high humidity climate environment, but also more resistant to dry heat, not cold, avoid frost, south of the Tropic of Cancer of China can safely winter in the open field, north of South China and Central China, North China are only suitable for potted plants, winter moved indoors or greenhouse. Bougainvillea has low requirements for soil fertility, suitable for sand or clay, able to withstand water and moisture, and also able to withstand drought. The potted flowers of Bougainvillea triangularis were forced to dormancy due to the temperature dropping to a certain extent. In the non-dormancy period, Bougainvillea triangularis appeared abnormal flower dropping due to insufficient light, and the flowers withered early due to sufficient water. Bougainvillea triangularis in the dormancy state was insensitive to light intensity, but its life span was long due to low temperature and low water content.

Cuttage Propagation of Bougainvillea delavayi

Triangle plum commonly used cuttage propagation and seedling easy, May, June cut mature lignification branches, 2-year-old branches cut into 10 cm long cuttings, inserted into the culture soil (with plain sand plus one-third humus or sawdust, add appropriate amount of water to stir evenly), inserted with plastic film sealed. Rooting can take place at 20℃ to 25℃ in 25 days, and can be divided into pots in 2 to 3 months. If you want to obtain ideal new seedlings should be used in the way of high-altitude cuttings for reproduction, this way does not affect the growth of the original plant, but also can obtain complete new seedlings, so often used by family flower growers and the method is simple, high survival rate, easy to transplant later, good management.

Cultivation method of triangular plum

1, select culture soil: triangular plum soil requirements are not strict, but afraid of water, not waterlogging, so must choose loose, good drainage culture soil, generally can choose humus soil 4, garden soil 4, sand 2 prepared culture soil, can also use dried pond mud mixed with some coal cake residue for pot soil, on the pot also need to mix 30 grams of decomposed dumpling fertilizer as base fertilizer.

2, reasonable fertilization: triangular plum general growth period every 7~10 days to apply liquid fertilizer once, fertilizer can be 10~20% decomposed bean cake, rapeseed cake water or human excrement water. In August, in order to promote the gestation of flower buds, phosphate fertilizer is applied, and fertilizer is applied once every 10 days. Liquid fertilizer such as 20% decomposed chicken, duck and pigeon dung and fish offal can be used. From October to the middle of November, phosphorus fertilizer should be applied once every half month, and the concentration of fertilizer and water should be 30~40%. After each flowering, topdressing should be added once, so that nutrients can be continuously supplemented during flowering.

3, water control before flowering: usually watering master the principle of "do not dry, do not irrigate, water must be transparent", but to bloom neatly, many flowers, water control must be carried out before flowering. The watering of triangular plum is controlled from September, and each watering can be repeated for half a month after the pot soil is dry and the branches and leaves are soft. After half a month, the normal watering is resumed. Do not fertilize during water control to avoid fertilizer burning roots. In this way, buds can bloom in about a month, and flowers open neatly and flourish.

4. Loosening and changing pots: Due to long-term watering, fertilization and rain erosion, the pot soil is easy to harden, so it is necessary to loosen the soil regularly and remove the weeds in the pot at the same time to facilitate the growth of triangular plum. Otherwise basin soil hardening, ponding, easy to cause root rot or poor growth. In addition, triangular plum growth faster, root system developed, fibrous roots many, need to change pot once a year.

Cultivation and Management of Bougainvillea chinensis

1. Temperature management: The suitable temperature for the growth of Bougainvillea chinensis is 15~30℃, of which 19~30℃ is from May to September, and 13~16℃ is from October to April of the following year. In summer, it can withstand the high temperature of 35℃. When the temperature exceeds 35℃, it should be properly shaded or sprayed with water or ventilated. In winter, the ambient temperature should be maintained at not less than 5℃. Otherwise, when the temperature is below 5 ℃ for a long time, it is easy to freeze and fall. Flowering needs more than 15℃ temperature, in order to prolong flowering should be in early winter cold before the arrival of timely move into the room, placed in sufficient sunlight, maintain a higher ambient temperature.

2. Light control: Triangle plum likes light and belongs to positive flowers. Insufficient light in growing season will lead to weak growth of plants, affecting pregnant buds and flowering. Therefore, seedlings except new pots should be placed in semi-shade all year round. Winter should be placed in front of the south window, and the lighting time should not be less than 8 hours, otherwise a large number of leaves will easily appear. Short-day flowers, the daily lighting time control in 9 hours or so, can be in a month and a half after the bud flowering.

3. Reasonable pruning: Bougainvillea grows rapidly, and attention should be paid to shaping and pruning during the growth period to promote the growth of lateral branches and more flowering branches. The number of pruning is generally 1~3 times, not too much, otherwise it will affect the number of flowering. After each flowering, the remaining flowers should be removed in time to reduce nutrient consumption. After flowering, over-dense branches, inner bore branches, excessive branches and weak branches should be thinly cut. Other branches should not be pruned or only slightly pruned. It is not suitable to cut again, so as to shorten the growth period of the next round and promote early flowering and multiple flowering.

4, flowering control: if you want to see the National Day horn plum, you can put the pot in advance in the dark room for light-proof treatment, because it is a short-day flower. The time is about the beginning of August, the potted triangular plum is placed in an environment without light leakage, and the light is completely lost from 5 p.m. to 8 a.m. on the second day every day, so that it is maintained for 50 days, and water is sprayed every day to cool down. Normal watering, weekly increase phosphorus, potassium fertilizer or shoe fertilizer. Such a national day can see the gorgeous horn plum.

What if the triangle plum doesn't bloom?

1. Light: Bougainvillea loves light, so it can be placed in a sunny place. This is not only beneficial to its vegetative growth, but also conducive to reproductive growth. After strong sunlight treatment, the internode of branches is short, the growth is full, the flower quantity is many, the flower color is deep, the flowering period is long.

2, pruning: triangular plum growth period is long and fast, so it is necessary to properly prune and pick.

3. Moisture: Triangle plum should start to control water in mid-August. After watering once, wait until the leaves and buds are drooping before watering. The degree of water control is subject to the plant not dying. Repeat this treatment until the embryonic form of flowers appears between the axils of the branches, and then gradually restore normal watering. Water control can increase the concentration of cell fluid and promote flower bud differentiation and formation.

4, fertilization: Bougainvillea is very sensitive to urea, such as improper fertilization period, improper proportion, it may produce luxuriant foliage and less flowers phenomenon, so urea must be particularly cautious. Summer temperature is high, rain more, plant easy to grow, can not apply urea alone, can apply some fertilizer with rotten vegetable leaves, it is best to use 0.2%-0.3% potassium dihydrogen phosphate solution for foliar topdressing, fertilization once every half month. Urea can be applied once at the early stage of flowering to facilitate the growth of flowering flowers.

Cautions for triangular plum farming

1, the growth period of triangular plum should be appropriate to ensure the temperature of triangular plum, generally in winter to maintain above 5℃, the minimum can not be lower than 3℃.

2, triangular plum more like the sun, but in the summer time to carry out appropriate shade treatment, while in the winter time, to ensure 8 hours of light.

3. In terms of soil selection, the breeding of Bougainvillea chinensis should choose fertile, loose and strong drainage soil.

4. The watering of triangular plum should be appropriate, and certain drainage should be ensured during the rainy season, otherwise the phenomenon of rotten roots will occur.

5. Before flowering, the pots can be properly turned over and the soil can be properly trimmed.

Prevention and control of diseases and insect pests of Bougainvillea chinensis

1. Leaf spot disease

[Harm symptoms] The disease spot is yellow brown at the beginning, surrounded by yellow-green halo, and then expands into a nearly round or irregular disease spot with dark brown edges. In the later stage, black dots appear on the disease spot.

[Prevention and control method] If a small amount of disease spots are found, apply Dakening Cream on them, cut off the branches with more diseases, generally use 50% carbendazim WP 500 times solution for prevention and control at the initial stage of disease, spray once every 7~10 days, and spray once on the fourth day according to actual experience, and then spray once every 7 days. 3~4 times in succession, the control effect is good.

2. Brown spot disease

[Harm symptoms] The injured leaves produce yellow-brown to light brown spots with a diameter of 0.1~0.5 cm on the leaves.

[Control method] A small number of diseased leaves are removed and burned in time. In the early stage of the disease, use 70% mancozeb wettable powder 400 times solution, spray once every 10 days for 3~ 3 consecutive times.

3. Scale insects

[Harm symptoms] In the environment of poor light, poor ventilation, high temperature and high humidity, it is easy to cause a variety of scale insects.

[Control method] 45% malathion emulsifiable concentrate 1000 times spray kill.
