What is the cultivation and cultivation method of triangular plum? How to control the pruning time of triangular plum? ...

Triangular plum is what we often call leaf flower or safflower kudzu. Triangular plum is an important ornamental flower in common urban greening, which is often planted on flower racks or walls to climb and grow. The beautiful flowers bloom on its overhanging branches at the turn of winter and spring. In addition, it can also be planted as a flower hedge, which is also very chic, simple and beautiful. Now let's take a look at the configuration method of triangular plum and the mastery of pruning time!

What is the cultivation and cultivation method of triangular plum?

Triangular plum flowers are very small, three gather, outside there are three large purple, red, orange or white plastic bracts wrapped, bracts outside the image of leaves but the color is very bright, do not pay attention to observation, often regard it as petals, hence the name of triangular plum.

Triangular plum likes a warm and humid climate and is not cold-resistant, so it can only be used as a potted plant in the Yangtze River basin and the northern region. Triangular plums require plenty of sunshine and often do not blossom or rarely blossom in the shade. In winter, it is best to put it on the indoor sunny windowsill of 18 houses and 20 degrees. Potted soil is not strict, and fertile sandy loam is more suitable. The pot can be changed in early spring, and rotten fertilizer and water will be applied once every half a month during the growth period. after the spring is warm, the pot can be moved to the balcony or the sunny place in the courtyard. If the sun is not enough, the blossom will be little or no at all.

There are often dry, hot and gale winds in North China from May to June, which do great harm to the growth of leaves and flowers, so attention should be paid to moving indoors. As the temperature rises, watering can gradually increase. The potted plum in the north is in full bloom from May to June, when more fertilizer is needed, and rarefied liquid fertilizer is applied once a week. Attention should also be paid to shaping and pruning in summer and autumn to keep the plant shape beautiful. Coring should be carried out in summer to control vegetative growth and promote flower bud formation.

If the temperature in the room is lower than 18 degrees in winter, some leaves will wither and fall. At this time, we should pay attention to controlled watering. Excessive dampness can easily cause rotten roots. If it is not used as an indoor climbing vine, it is appropriate to prune after flowering to promote multiple new branches and grow into a spherical crown with a beautiful and colorful plant shape.

Triangulated plum is easy to reproduce. In June, semi-lignified branches were cut into 10ml 15cm segments and inserted in a basin filled with plain sandy soil. Under the condition of 25 degrees, they can take root in about a month, but at lower temperatures (18ml, 20 degrees), they take root more slowly. Cuttings after rooting, planted in Xiaopeng, should be placed in a semi-shady place, slow seedlings to restore growth for a period of time, can gradually see the light, normal management.

In addition, strips can be used to breed. Most of the 1-2-year-old branches of the lower part of the plant are pressed into the basin from May to June, or the branches are pressed into the soil with another basin; the branches are pressed in a ring, and the peeling width is more than twice the diameter of the branches.

After pressing, cover the soil and keep the basin soil moist; it can take root for more than a month, and cut off the basin for more than two months. Although striping propagation is more troublesome, but the seedlings grow up quickly, which is suitable for the needs of less reproduction in family flower cultivation.

What is the cultivation and cultivation method of triangular plum? How to control the pruning time of triangular plum?

Common triangulated plums include:

(1) Red triangular plum: bracts crimson

(2) Brick red triangular plum: bract brick red

(3) orange triangulated plum: bracts orange yellow

(4) Purple triangle plum: this variety is relatively hardy and will not be frozen if it is put indoors at 5 degrees in winter.

Triangular plum is of great ornamental value, and it is also a kind of Chinese herbal medicine, which has the effect of removing blood stasis and reducing swelling.

How to control the pruning time of triangular plum?

The pruning of triangular plum is mainly to cut out the robust, cut out the space, cut out the layers, cut out the shape, cut out the trunk and branch curvature. Cutting off the weak branches and shortening the long branches is actually reducing consumption, making the retained branches and new branches more robust, losing and gaining, and it is necessary to be willing to cut them in order to get robust bonsai. People should be open-minded, trees should be hollow, and there must be room between branches to grow and receive sunlight. Therefore, bonsai must have 5 layers of 3murs, and the inner hall branches should be removed as far as possible. In order to make the triangular plum have a beautiful shape, the main branch should be stout and have a certain curvature, which represents a kind of vicissitudes of life and simplicity, and can see the whole through a small part, like a big tree, in order to basically have the meaning of bonsai.

Trimmed plum is generally pruned after spring germination, which can determine which branches are weak, which are strong, and which are dry. Of course, they can also be pruned at ordinary times, such as moderate pruning after flowering, cutting off pedicels, retraction of flower branches 1 and 3, thinning of weak branches, short branches, bore branches, winter combined with basin soil pruning, and so on. Triangular plum pruning depends on trees, types, and pots, and should be used flexibly, young trees, potted flowers, shaped and unshaped plants should be treated differently.

The size of the basin determines the weight of pruning.

Small basin, can not cultivate big trees (soil nutrition and growth space is not enough), large basin is not suitable to cultivate small seedlings (waste of space). Generally, the pot height accounts for 1/3 of the whole plant, and the plant accounts for 2/3, which is more appropriate. The plant is too tall and too large, it appears top-heavy and unstable, and the basin size must be taken into account when pruning.

Trimming is divided into heavy cutting, medium cutting, light cutting and retraction:

1. Heavy cutting: the branches are basically cut off, leaving the tree stump and several major branches, and the remaining major branches should also be cut very short. In particular, the branches that are not needed and those that destroy the plant type should be completely cut off. Re-cutting is generally used when the shape is changed.

2. Medium shearing: the specific gravity shearing should be lighter, only cutting off some dead branches and unnecessary branches, and the branches with good growth position will only be shortened, and the whole tree shape will not change too much. Medium scissors are generally used on shaped bonsai.

3. Light pruning: just cut short some weak branches, cut off diseased branches, cut healthy branches slightly, generally use them in seedlings, seedlings and young trees, and try to preserve more branches to form a strong tree potential, so as to facilitate photosynthesis and make the seedlings grow fast.

4. Retract: cut all the branches short so that the shape of this year's tree is about the same as that of last spring, so as to make room for the plant to grow and blossom, make the new branches stronger and bloom more beautiful and spectacular. Sometimes the four pruning methods cannot be completely separated and must be combined organically.

Branches that must be pruned:

Withered stakes and branches (places where diseases and insect pests are reduced to hide).

Riding branch (branch that grows upward at right angles to a flat branch).

Inner branch (weak branch growing inside the crown, also known as shade branch).

Axillary branch (branch that emanates from the base of the main branch).

Parallel branches (two branches grow close together and grow in parallel directions), the weak one must be cut off.

Grow branches (branches that grow upward especially vigorously from the base of the trunk and destroy the plant type).

Cut off the weak branches from the cross branches and wipe off the buds that do not need to be kept.

Overlapping branches (upper and lower branches, cutting off the weak one).

Culture methods of triangular plum family culture methods and matters needing attention of triangular plum

Soil selection of Prunus mume culture

The culture soil of Prunus mume is mature by accumulation of loam, cow dung, rotten leaf soil and sand, and then add appropriate amount of bone powder when it is used. During cultivation, the triangular plum should be planted correctly, filled with culture soil and watered thoroughly.

Orchard soil: rotten leaf soil: sand is mixed at 5:3:2, or peat soil: rotten leaf soil: sand: perlite is mixed at a ratio of 5 to 2.

Watering method of Prunus mume culture

With the acceleration of growth in spring, it needs to be watered every day, and often sprinkle water to its leaves and around to increase air humidity, air humidity is insufficient, it is very easy to fall leaves.

In summer, water was watered twice a day, sprayed in the morning, and watered once after 4: 00 in the afternoon. After watering once before flowering, the leaves or buds were watered again.

When the temperature is cool in autumn, keep the basin soil moist. When the temperature is low (about 10 ℃), less watering makes the basin soil dry. However, if the indoor temperature is kept above 15 ℃, it is appropriate to water more to make the basin soil moist.

Watering is controlled in winter, and the basin soil is not dry or irrigated.

Fertilization method of Prunus mume culture

Triangle plum likes fertilizer. After the weather gets warmer in spring, nitrogen fertilizer is applied every 10 to 15 days, cake fertilizer and water is applied once a week during the growing period, and phosphate fertilizer is applied several times during flowering. Reduce the amount of fertilizer application after cool autumn, and stop fertilization in winter. During the growing and flowering season, 1000 times of potassium dihydrogen phosphate solution can be sprayed on the leaves for 3 times, or general fertilizer should be applied once every 10 days.

Note: triangulated plum is very sensitive to urea, such as improper fertilization, it may produce luxuriant leaves and few flowers, so urea should be applied with special caution.

Light and temperature requirements of Prunus mume culture

The suitable temperature for the growth of Prunus mume is 20-30 ℃, and the winter temperature below 5 ℃ is easy to be frozen and fallen leaves.

Triangular plums like the light, the lack of light in the growing season will lead to the weakening of plant growth and affect flowering. Winter should be placed in bright places, and the daily light can not be less than 8 hours, otherwise a large number of fallen leaves are easy to appear.

Matters needing attention in the culture of triangular plum

Triangular plum is not cold-resistant, it is easy to freeze to death with severe frostbite, so we must pay attention to temperature changes. Generally speaking, if the temperature is lower than 5 ℃ for a long time, it may be frozen to death, even in winter in the south, the lowest can only reach 3 ℃ or so.

Triangular plum is afraid of waterlogging, so potted triangular plum must not accumulate water in the basin.

Triangle plum is resistant to pruning, don't be afraid of bad pruning, frequent pruning will help to blossom more.

Cultivation methods of Prunus mume

Triangular plum is known as light leaf flower, also known as three-leaf plum, towel, rhododendron, triangular flower, etc., is a rattan shrub plant of the family Araceae, native to Brazil, planted in courtyards and parks in southern China as ornamental plants, and cultivated in greenhouses in the north. It can also be used for bonsai, hedgerows and pruning modelling. Let's take a look at the cultivation methods of triangular plum.

How much is the price of triangular plum?

The price of triangular plum is generally based on the height, crown width and ornamental performance of triangular plum. Generally, a triangular plum with a diameter of 2 cm, a crown width of 200 cm and a crown width of 100 meters is about 100 yuan per tree. Of course, it is generally like a sapling with a height of 30 cm and a crown width of 30 cm, and its price is generally 10 yuan and 20 yuan per tree.

Cultivation environment of Prunus mume

Triangulated plum is a tropical plant, which likes the climatic environment of high temperature and humidity, and is more resistant to dry heat, not resistant to cold, and avoid frost. It can safely winter in the open field south of the Tropic of Cancer, and it is only suitable to be potted in the north of South China and even in the vast areas of Central and North China. Move into the indoor or greenhouse in winter. Triangulated plum does not have high requirements for soil fertility, sand or clay are suitable, can withstand water and moisture, but also more resistant to drought. The potted plum flower is forced to dormancy because the temperature drops to a certain extent. In the non-dormant period, the triangular plum flower falls abnormally due to lack of light, and the flowers are withered early due to sufficient water. The triangular plum in the dormant state is not sensitive to the intensity of light, but it has a long life because of low temperature and long life because of less water.

Cutting Propagation of Prunus mume

Triangulated plum is often propagated by cuttings and seedlings are easy to raise. Cut mature Lignified branches in May and June, cut 2-year-old branches into 10 cm long cuttings, and insert them into culture soil (add 1/3 humus or sawdust with plain sandy soil, stir with proper amount of water). Seal with plastic film after insertion. The temperature can take root in 25 days from 20 ℃ to 25 ℃, and the pots can be divided in 2 to 3 months. If you want to obtain ideal new seedlings, you should use high-altitude cuttings to propagate, this way does not affect the growth of the original plant, but also can obtain complete new seedlings, so it is often used by family flower growers and the method is simple and the survival rate is high. it is convenient to transplant in the later stage and easy to manage.

Cultivation methods of Prunus mume

1. Select culture soil: Triangle plum is not strict on soil, but it is afraid of stagnant water and is not resistant to waterlogging, so it is necessary to choose loose and well-drained culture soil. Generally, 4 parts of humus soil, 4 parts of garden soil and 2 parts of sand can be selected. Sun-dried pond mud mixed with some coal cake dregs can also be used as basin soil, and 30 grams of rotten dumpling fertilizer should be mixed into the basin.

2. Rational fertilization: triangulated plum is generally applied liquid fertilizer every 7-10 days during the peak growth period from April to July, and the fertilizer can be used with 10-20% cooked bean cake, rapeseed cake water or human feces water. Since August, in order to promote the gestation of flower buds, fertilizer based on phosphate fertilizer has been applied every 10 days, and 20% liquid fertilizer such as rotten chicken, duck, pigeon dung and fish can be used. From October to mid-November, it is necessary to apply phosphate fertilizer every half a month, and the concentration of fertilizer and water is 3040%. In the future, topdressing should be applied once after each flowering, so that the flowering period can be replenished continuously.

3. Water control before flowering: usually watering should master the principle of "no dry, no watering", but to blossom neatly and more, water control must be carried out before flowering. The watering of triangular plum has been controlled since September, and each watering can be repeated for half a month until the basin soil is dry and the branches and leaves are soft and sagging, and the normal watering can be resumed after half a month. Do not apply fertilizer during the water control period, so as not to burn the root system. In this way, it takes about a month to bud and blossom, and the flowers bloom neatly and flourish.

4. Loosen the soil and change the basin: due to long-term watering, fertilization and Rain Water erosion, the basin soil is easy to solidify, so it is necessary to loosen the soil regularly and remove weeds at the same time to facilitate the growth of Prunus mume. Otherwise, basin soil hardening, stagnant water, easy to cause root rot or poor growth. In addition, the growth rate of triangular plum is faster, the root system is developed, and there are many whisker roots, which need to be changed once a year.
