Key points of cutting Propagation and cultivation Management of potted Prunus mume (picture)

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.

Cultivation and Management of Prunus mume

1. Temperature management: the suitable temperature for the growth of Prunus mume is 15: 30 ℃, among which it is 19: 30 ℃ from May to September and 13: 16 ℃ from October to April of the following year. When the temperature is above 35 ℃ in summer, shading or spraying water and ventilation should be taken properly, and the ambient temperature should be maintained at no less than 5 ℃ in winter, otherwise the long-term temperature below 5 ℃ will be easy to freeze and fall leaves. Flowering needs a temperature of more than 15 ℃. In order to prolong the flowering period, it should be moved indoors in time before the arrival of the cold spell at the beginning of winter and placed in a sunny place to maintain a high ambient temperature.

2. Light control: triangulated plum is a positive flower. Lack of light in the growing season will lead to plant growth weakness, affecting pregnant buds and flowering, so seedlings except fresh pots should be placed in the semi-shade all the year round. Winter should be placed in front of the southward window, and the lighting time should not be less than 8 hours, otherwise a large number of fallen leaves are easy to appear. Short-day flowers, the light time every day is controlled at about 9 hours, and it can bud and blossom after one and a half months.

3. Reasonable pruning: triangular plum grows rapidly, and attention should be paid to shaping and pruning during the growing period, so as to promote the growth of lateral branches and produce more flowering branches. The number of pruning is generally 1-3 times, should not be too much, otherwise it will affect the number of flowering. After each flowering, the residual flowers should be removed in time to reduce nutrient consumption. After the flowering period, the overdense branches, bore branches, overgrown branches and weak branches should be thinned, and other branches should not be pruned or only slightly trimmed, so it is not suitable for heavy pruning, so as to shorten the growth period of the next round and promote them to bloom early and blossom many times.

4. Florescence control: if you want to see the horn plum on National Day, you can put the pot in the dark room in advance to avoid the light, because it is a short-day flower. The time is around the beginning of August, the potted triangular plum is placed in a light-proof environment, and there is no light at all from 5: 00 p.m. to 8: 00 a.m. on the second day, so as to keep it for 50 days and spray water to cool down every day. Normal watering, weekly application of phosphorus, potassium liquid fertilizer or foot forgiveness fertilizer. In this way, gorgeous horn plums can be seen on National Day.

What if the triangular plum does not blossom?

1. Lighting: triangular plum 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. The plants treated by strong sunlight had short internodes, full growth, large number of flowers, deep flower color and long flowering period.

2. Pruning: the growing period of triangulated plums is long and fast, so pruning and coring should be done properly.

3. Moisture: Triangle plum should start to control water in the middle of August. After watering once, wait for the leaves and buds to droop before watering. The degree of water control is based on the fact that plants do not dry and die. After such repeated treatment, the embryonic form of flowers appeared in the axils of the leaves at the end of the branch, and then gradually returned to normal watering. Water control can increase the concentration of plum cell fluid and promote the differentiation and formation of flower buds.

4. Fertilization: Triangle plum is very sensitive to urea, such as improper fertilization period and improper proportion, it may produce the phenomenon of luxuriant leaves and few flowers, so urea must be applied with special caution. The summer temperature is high, Rain Water is more, and the plant is easy to grow. You can not apply urea alone. You can apply some fertilizer made from rotten vegetable leaf retting. It is best to use 0.2% KH2PO4 0.3% solution as foliar topdressing, fertilizing once every half a month. Urea can be applied once at the initial stage of flower branch growth to facilitate flower branch growth.

Matters needing attention in the culture of triangular plum

1. The growth period of triangular plum should properly ensure the temperature of triangular plum, which should be kept above 5 ℃ in winter, and the lowest should not be less than 3 ℃.

2. Triangular plum prefers sunshine, but it should be properly shaded in summer and 8 hours of light should be guaranteed in winter.

3. In the aspect of soil selection, the cultivation of Prunus mume should choose the soil with relatively fertile, loose and strong drainage performance.

4. The triangular plum should be watered properly and a certain degree of drainage should be ensured in the rainy season, otherwise there will be the phenomenon of rotten roots.

5. Triangular plum can be properly turned over to change soil before flowering, and can be pruned properly at the same time.

Control of Diseases and insect pests of Prunus mume

Culture methods and matters needing attention of potted triangular plum

Triangular plum has ornamental value, bright colors such as flowers, has been introduced and cultivated in large numbers, and has become a good product of garden planting and indoor potted plants. Then how to raise triangulated plum? What do you need to pay attention to in breeding? Next, let's take a look at the culture methods and matters needing attention of triangular plum.

I. Culture methods and matters needing attention of triangular plum

1. Soil: Prunus angustifolia is lax on soil, growing well in clay heavy soil with good drainage and rich minerals, barren, alkali-resistant, drought-resistant and avoid stagnant water. The slightly sour soil is most favorable for the growth of Prunus mume.

2. Watering: triangular plum should be watered once a day in spring and autumn, once in the morning and evening in summer, once in the morning and evening after the emergence of watering buds in winter, and spraying water to the leaf surface twice at the same time. It is necessary to prevent stagnant water in the rainy season so that the plants will not rot and die.

3. Temperature: the suitable temperature for the growth of Prunus mume is 15-30 ℃. Proper shading or measures such as water spraying and ventilation should be taken in summer, and the ambient temperature should be maintained at no less than 5 ℃ in winter.

4. Fertilization: in addition to applying sufficient basic fertilizer in the basin soil, triangulated plum should also be fertilized in the growing season. Add a small amount of potassium dihydrogen phosphate and spray 0.1% potassium dihydrogen phosphate on the leaf. 2% potassium dihydrogen phosphate solution, alum fertilizer water was applied once a week during flowering, and 0.2% potassium dihydrogen phosphate was sprayed on the leaf.

5. Illumination: the seedlings of triangular plum should be placed in the semi-shade place except for the new ones all the year round. Winter should be placed in front of the south window, and the lighting time should not be less than 8 hours.

6. Propagation: triangulated plum cuttings as thick as arms and as thin as incense can be used for cutting; coarse branches have late roots and fast shaping; annual lignified green branches are easy to grow new roots and have a high survival rate.

7. Pruning: trimmed plum leaves and peanuts grow strongly, so they need to be shaped and pruned every year. Leaf flowers are often propagated by cuttings, so it is easy to raise seedlings. In May and June, mature lignified branches are cut, which are 20 centimeters long, inserted into sand basins, covered with glass, kept moist, rooting in about a month, and flowering in two years.

II. The relationship between Triangle Plum and Home Environment

1, triangle plum beautifies the home, triangle plum blossom, gorgeous full branches, bracts are purple blue, scarlet, peach, crimson, orange and other kinds, are very gorgeous. There are also hanging towels, also known as wool towels, flowers gather to form a group, red as fire, especially beautiful, very suitable for planting in parks, flower beds, scaffolding on both sides of the door, climbing for the door.

2. Triangular plum can measure the quality of the living environment at home. It likes warm and humid climate and is not cold-resistant. It can only survive the winter safely when it is more than 3 ℃ and blossom only when it is over 15 ℃. Like plenty of light. Lax requirements on the soil, in good drainage, mineral-rich clay loam in good growth, barren resistance, alkali resistance, drought resistance, avoid stagnant water, resistant to pruning. Except in the south of China, it can be cultivated in open field for overwintering, and pot and greenhouse cultivation are needed in other areas. Sandy loam with good drainage is the most suitable for soil.

The breeding methods and matters needing attention of Triangle Plum have been introduced. I hope it will be helpful to everyone. Triangular plum has bright colors and high ornamental value, so we can raise some at home.

The breeding method of triangular plum the culture method of triangular plum

Triangular plum is a very common household plant, because it is very easy to feed, unique design and color, and suitable for local decoration in study, living room, bedroom and other areas, so many flower friends choose. Next, let's learn about the breeding method and breeding method of triangular plum.

The Propagation method of Prunus mume

There are three main propagation methods of Prunus mume: cutting, high pressure and grafting, the most important of which is cutting propagation. The suitable cutting time is 3-6 months. High-pressure propagation takes root for about a month, and transplanting is the best in spring. During the growing period, it is necessary to pick the heart to promote the differentiation of flower buds and the germination of lateral branches.

The main results are as follows: 1. the best cutting time is spring and summer and autumn. In spring (March-April), the pruned annual branches can be used for cutting (also known as old cutting), but the survival rate is not too high, only about 70%. Summer and autumn is the peak growing season of triangulated plum, so the semi-lignified branches of the same year are selected for tender cutting, and the survival rate can reach more than 90%. As long as the management is strengthened, it can blossom in that year.

2. The cutting substrate is relatively random, and flower friends can use local materials. The matrix can choose coarse sand, fine sand, sandy loam with good permeability, loose soil that is not too fertile, or mashed and burnt briquette, cinder and so on. Then add 0.1% carbendazim for disinfection, accumulate the soil and cover it with a film for 7-10 days. The slotting machine is 1 m-1.2 m wide, 15-20 cm high and unlimited in length.

3. In the treatment of cuttings, short and stout annual branches with short internodes were cut into 8-10 cm long, leaving only 2-3 leaves on the cuttings. Treatment with rooting element before cutting can promote its early rooting and more rooting.

4. The suitable cutting depth is 3-4 cm (equivalent to 1 / 3 or 2 / 5 of cuttings). Before inserting, punch the hole with the insertion rod, then insert the cuttings, and press the matrix at the base of each cuttings slightly to make the cuttings come into close contact with the matrix. Then pour the water once and cover it with a film to keep warm.

Culture method of triangulated plum

1. Soil selection

The cultivated soil is made of loam, cow dung, rotten leaf soil, sand and so on, and appropriate amount of bone powder is added when used. During cultivation, the triangular plum should be planted correctly, filled with culture soil and watered thoroughly. In the process of cultivation, it is often necessary to pick the heart to form a clump and low plant type. A bracket can also be set up to make it climb.

The following soil formulations can be used for families: garden soil: rotten leaf soil: sand = 5RV 3RV 2; peat soil: rotten leaf soil: sand: perlite = 5Rd 2RV 2VR 1.

two。 Watering method

Triangular plum has a large demand for water, especially in midsummer, lack of water is easy to cause defoliation, affecting growth and flowering. Therefore, the summer flowering period is watered twice a day, sprayed in the morning, and watered once after 4 pm; watering can be reduced appropriately after flower fade, and the soil will cause fallen leaves and rotten roots if the soil is too wet; watering is controlled in winter, and the basin soil is not dry or irrigated. However, the water should be deducted 4-5 weeks before flowering, that is, after watering once, the leaves or buds should be watered again, which is beneficial to the differentiation and formation of flower buds.

Triangular flowers like wet soil and are afraid of water stains. 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. Triangular flowers and leaves, summer water consumption is large, it is best to water once every morning and evening, so that the soil is in a moist state, increase the number of times to sprinkle water to its leaves and around. When the temperature is cool in autumn, keep the basin soil moist. In late autumn, winter and early spring, 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.

3. Fertilization method

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 could be sprayed on the leaves for 3 times, or 1000 times of Huaduoduo general fertilizer could be applied once every 10 days.

Stop fertilizing when the temperature is cool in autumn. Do not apply fertilizer when the temperature is low in late autumn, winter and early spring. However, if the temperature is above 15 ℃, the mixed liquid fertilizer can be applied every other month.

Triangular plum is very sensitive to urea, such as improper fertilization, it may produce luxuriant branches and few flowers, so we should be very careful when applying urea.

Spring blossom is the vegetative growth period of Prunus mume, and urea can be applied every other week. This can not only supplement the consumption of post-anthesis plants, but also promote the growth of new branches and lay a good foundation for reproductive growth.

Some liquid fertilizer should be applied thinly in summer, and 0.2%-0.3% potassium dihydrogen phosphate solution can be used as foliar topdressing once every half month. Urea is still needed at the initial stage of flower branch growth to facilitate flower branch growth.

4. Light and temperature requirements

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.

5. Matters needing attention

The main results are as follows: (1) the light-loving plants of the genus Prunus should be sunny, whether potted or planted on the ground. the plants treated by strong sunlight have short branches, full growth, many flowers, deep color and long flowering period. Lack of light results in weak growth of new branches, dim leaves and little or no flowering.

(2) triangular plum bonsai mostly choose rectangular or oval purple sand pottery or glazed pottery basin, the color should not be too deep, in order to set off the bright color of triangular plum bracts. The basin soil should be mixed with nutrient soil rich in humus, loose and well drained, and the basin should be put on the basin in the period of stable temperature in spring.

(3) the cool temperature in autumn can reduce the supply of water and fertilizer, make the basin soil moist and ensure sufficient light. When the temperature drops to about 10 ℃, you should timely move the indoor light sufficient place or close the balcony where there is light to cultivate. Because the indoor air humidity is low, should often sprinkle water to its leaves and around to increase the air humidity.

(4) Triangle flower is not cold-resistant, winter temperature is lower than 7℃ will be deciduous. But winter defoliation, spring temperature will rise after the re-growth of leaves, but the growth is not good. Therefore, it is best to keep the room temperature around 10℃ in winter. In winter, triangular flowers should be placed on the windowsill with sufficient light, and different water and fertilizer management should be carried out according to different temperatures. It should be sprayed around several times a day to increase air humidity.

The above is for everyone to introduce the triangular plum breeding methods and triangular plum breeding methods, we all understand it? More home knowledge please pay attention.
