Attention should be paid to "three fears and four essentials" in the cultivation of five-needle pine bonsai.
The five-needle pine bonsai is a favorite of many flower friends. It can not only be viewed at home, but also play a certain role in beautifying the environment. And five-needle pine bonsai in bonsai is also a relatively common species, but five-needle pine bonsai in the breeding of "three fears and four to" do you understand it?
Five-needle pine bonsai
The "three fears" are: first, they are afraid of getting fat. The requirement of five-needle pine for fertilizer is thin fertilizer and less fertilizer, and the thin liquid fertilizer can only be applied once a year from August to October. If the growth is exuberant in spring, you can apply less, and you can't apply fertilizer at ordinary times. Novice pine breeders often disrelish that it grows slowly and want to fertilize more to make it grow faster, which is counterproductive. Second, I am afraid of stagnant water in the basin. If too much watering, the ventilation in the basin will be blocked, resulting in root rot and withered branches and leaves. As the saying goes, "dry pine and wet cypress" is the reason. Third, I am afraid to pour the basin frequently. Potted plants only need to change pots every 3-4 years, and the time should be from late September to early October, or from February to March. However, some pine breeders choose pots for shaping, but change pots indiscriminately at the wrong time, resulting in death because of changing pots too often.
The "four essentials" are: first, to see more sunshine, it is best to put it in a sunny ventilated place. When the air is dry, you can spray water on the leaves twice in the morning and evening. Second, pruning should be carried out during the dormant period to prevent the loss of too much sap and damage its vitality. Third, keep it in a ventilated, sunny, warm, moist, smoke-free room in winter. Fourth, regular observation should be made to prevent and control diseases and insect pests in time.
Three fears and four essentials in the maintenance of five-needle pine bonsai
Five-needle pine bonsai maintenance is three fears and four essentials.
The five-needle pine (Pinus parviflora) gets its name because of its clusters of leaves. There are many varieties of five-needle pine, among which the pine with the shortest needles (about 2 cm in length) and compact branches is the most valuable. Japanese five-needle pine is a plant of the genus Pinus in pine family. Distributed in Japan and other places, has been artificially introduced and cultivated.
Three fear, one fear fat. The requirement of five-needle pine is to apply thin fertilizer and apply thin liquid fertilizer only once a year from August to October. If the growth is exuberant in spring, you can apply less, and you can't apply fertilizer at ordinary times. Novice pine breeders often disrelish that it grows slowly and want to fertilize more to make it grow faster, which is counterproductive. Second, I am afraid of stagnant water in the basin. If too much watering, the ventilation in the basin will be blocked, resulting in root rot and withered branches and leaves. As the saying goes, "dry pine and wet cypress" is this reason. Third, I am afraid to change the basin frequently. Potted plants only need to change pots every 3 to 4 years, and the time should be from late September to early October, or from February to March. However, some pine breeders choose pots for modeling, but change pots indiscriminately at the wrong time, resulting in death because of changing pots too often. Fourth, to see more sunshine, it is best to put it in the sunny ventilation place, when the air is dry, you can spray water on the leaves twice in the morning and evening. Second, pruning should be carried out during the dormant period to prevent the loss of too much sap and damage its vitality. Third, keep it in a ventilated, sunny, warm, moist, smoke-free room in winter. Fourth, regular observation should be made to prevent and control diseases and insect pests in time.
Five-needle pine is suitable to grow in loose, fertile and slightly acidic soil with good drainage. If the needle is too alkaline, the needles will turn yellow and fall off, so it is better to use natural mountain soil in basin soil. According to the proportion of basin soil, 3 parts of rotten leaf soil, 5 parts of garden soil, 1 part of compost and 1 part of sandy soil were mixed into nutrient soil. Generally, the basin should be changed every 2 to 3 years, and the time should be from February to March or from September to October.
Five-needle pine is a positive tree species, spring, autumn and winter should be kept in a sunny place, the needles are short and strong, the leaves are green, on the contrary, the needles are thin and easy to wither and yellow. But in the hot summer, the hot sun should be avoided around noon so as not to cause the needles to scorch. Spring and autumn are the growing season of five-needle pine, so it is necessary to keep the basin soil moist and promote the growth of branches and leaves. The slow growth of five-needle pine in summer has entered a dormant period, but the water evaporation is large, watering every morning and spraying water to the leaves in the evening. Control watering in winter and maintain its lowest temperature. After the five-needle pine is formed, do not apply too much fertilizer, otherwise it is easy to hurt the root.
Five-needle pine potted plants should choose a dry and ventilated environment, too wet and too shady are disadvantageous to its growth. Watering should be appropriate, usually once a day in spring and autumn, twice a day in summer, and once a few days in winter. At the same time, we should pay attention to the flexible control of weather changes. It is better to pour it with natural water. If you use tap water, you can keep it in the tank for a few days and then pour it.
Five-needle pine does not require high fertility, fertilization should not be too much and too thick, too much fertilization will make shoots grow, needles longer, hindering ornamental value. Generally speaking, only two fertilizers are applied during the growth period of spring and autumn, organic liquid fertilizer (cake fertilizer and water) is applied before germination or after thick leaves in spring, and thicker fertilization can be applied appropriately in autumn to promote robust growth. Stop fertilizing after October.
Attention should be paid to the following three points in the maintenance process:
1, watering too frequently, or more Rain Water in June every year, the basin soil is often too wet, coupled with poor drainage and stagnant water in the basin, causing anoxia in the soil, causing rotten roots and yellowing needles.
2. In the hot summer, the water evaporates quickly and is not watered enough, which will cause the needles to scorch. If the hot sun exposure, the basin soil is too dry, the five-needle pine will also appear top needle tip scorched, if continue to lack of water, the plant will eventually die.
3. The five-needle pine has been put indoors for a long time, lack of light and air, which violates the habit that the five-needle pine should receive light outdoors, or suddenly move to the outdoor to encounter exposure, the same will happen. In order to avoid the withering and yellowing of five-needle pine leaves, corresponding prevention and rescue measures should be taken according to the above reasons.
Tips for potted five-needle pine
One is "determined". That is, when planting on the basin and changing the basin, the five-needle pine likes the slightly acidic soil with fertile and smooth drainage. If planted in alkaline soil, the leaves will soon turn yellow and die, and the basin soil is better with natural mountain mud. It can also be made by mixing 3 parts of rotten leaf soil, 5 parts of mountain soil, 1 part of compost and 1 part of sand, and mix well with 1% ferrous sulfate and sulfur powder. The basin should be changed every 2-3 years, that is, during the dormant period, that is, from February to March and from October to the first and middle of November, do not break the soil ball, cut off the old root and rotten root, replace it with new soil, add a small amount of cake fertilizer, bone powder and cover with culture soil, the size of the basin should be appropriate when changing the basin, the basin should not be too deep, and the deep basin is easy to cause rotten roots due to stagnant water. the bottom of the basin should be added with a layer of 5 pieces of tile 10 cm thick. The tile of the bottom hole should be placed in the shape of "human", covered with brown sheet or plastic yarn, the basin soil on the basin should not be too full, and the water mouth must be cut, which should not only prevent the basin from being too small to damage the root system or squeeze it into the basin, but also prevent the basin from being too large, affecting the absorption of fertilizer and causing stagnant water, tamping it with bamboo sticks after planting, watering through it, and putting it in a cool place for 1 week.
The second is "repair". That is, picking buds and pruning, in the spring shoot growth period, in order to make pine needles short and compact, the new shoots should be removed by hand, and should not be cut with scissors, and should not be sprayed with water after picking, but should be sprayed only after the wound is dry, and should be pruned in time for over-dense branches and dead branches of diseases and insects. From October to November, the leaves at the base of the five-needle pine naturally yellowed and the leaves should be changed, and the leaves should be removed gently in time. This kind of yellow leaves not only affect beauty, but also create conditions for diseases and insect pests to survive the winter.
The third is "adjustment". That is, regulating moisture, "dry pine and wet cypress" is the experience of flower farmers. Five-needle pine likes drying and is not resistant to moisture. It is necessary to keep the basin soil moist in the spring growing season, slow growth in summer into the dormant period, requiring less water, but the high temperature cool department waters once in the morning and spray water to the leaves in the evening; water once every three days in spring and autumn and once every two weeks in winter, as long as the minimum living requirements are maintained, watering should be controlled.
The fourth is "suitable". That is, appropriate fertilization, five-needle pine ridge resistance, fertilization can not be more, otherwise the pine needle will grow too long and not beautiful. Spring fertilizer should be applied once 10% cake fertilizer before germination and after leaf expansion, autumn fertilizer at the end of August can be thicker, 25% cake fertilizer water can be used, and no fertilizer can be applied after October. Usually, 0, 1% urea and 0, 1% potassium dihydrogen phosphate can be sprayed, 1% color can be sprayed once every 2 weeks, and fertilizer spraying should be carried out in the morning, evening or cloudy days.
Fifth, "prevention". That is, to prevent diseases and insect pests, the diseases of five-needle pine include leaf withering disease and pine leaf falling disease. In addition to removing diseased leaves, 50% carbendazim or 70% methyl thiophanate can be sprayed at the initial stage of the disease. It is found that the pine shoot borer can be sprayed with 1200 times of 40 omethoate or Bt emulsion.
The sixth is "governance". That is to do a good job in the prevention and control of five-needle pine needle yellowing, because five-needle pine in the cultivation process is easy to appear needle yellowing phenomenon, loss of luster, it is very difficult to save, this is also a difficult problem in the cultivation of five-needle pine; the causes and prevention methods of its yellowing are briefly described as follows.
(1) rotten roots. When the new leaves were born that year, the yellow tip appeared between summer and autumn, and the leaf tip died after late autumn, which was mainly caused by improper watering, especially too often watering, which made the basin soil too wet for a long time, causing anoxia in the soil and root rot; some were planted too deep, the drainage layer was too shallow, or the drainage holes were blocked, resulting in water accumulation and rotting of the soil; some were protected in winter and spring, and the soil was buried too deep, and the roots were not cleaned in time in early spring, resulting in hypoxia and death of roots. Therefore, the soil moisture of five-needle pine should be kept between 15% and 30%, not less than 10% and higher than 35%.
(2) soil alkalization. The soil and water in the north are slightly alkaline, even if the potted soil is slightly acidic, but because the PH value of the irrigated water is on the high side, and no sulfur and ferrous sulfate are added to adjust the acidity, the leaves turn yellow after 6-10 months, and this yellowing can be solved by alum fertilizer water.
What are the key points for the maintenance of five-needle pine
Five-needle pine chic and vigorous, dark green leaves, beautiful and elegant posture, very poetic, is a tree species with high ornamental value. It likes sunny, warm and highly dry environment, slightly shady, but afraid of low humidity, suitable for growing in loose, fertile, slightly acidic soil. Therefore, in order to cultivate five-needle pine, it is necessary to do a good job of using soil, watering, fertilization, light and so on.
1) use soil. Five-needle pine pot soil requires drainage, good ventilation, slightly acidic sandy soil rich in organic matter, generally commonly used rotten leaf soil mixed with yellow soil (or black mountain mud) and sandy soil, the proportion is 6:3:1. The basin soil should not be alkaline, otherwise it is disadvantageous to growth, and the five-needle pine will yellowing and falling off.
2) change the basin. At the beginning of the five-needle pine basin, it is suitable to burn the mud basin, because of its good ventilation, easy to survive. Wait for the basin, and then change the form of simple, deep color purple sand pottery basin. The potted soil should be changed every 3-4 years, and the time of soil change should be from the end of February to the beginning of April or from September to mid-October. When changing the basin, cut off some old roots properly and water them thoroughly.
3) watering. Five-needle pine is most afraid of waterlogging to hurt roots, so watering should be appropriate, not too much, foliar water should be often sprayed, soil moisture should be kept between 15% and 30%, and natural water is the best. It is generally irrigated once a day in spring and autumn, twice a day in summer and once a few days in winter. At the same time, it should be controlled flexibly according to the changes of the weather.
4) fertilization. The method of thin fertilizer and less fertilizer should be used for five-needle pine, and fully rotten cake fertilizer should be applied. Fertilization for mature plants should be carried out in spring and autumn. Spring fertilizer is applied every 10 days for 3 months before germination, with a concentration of about 15%, to promote germination and branch growth. The weather is hot from July to August, 10% dilute fertilizer and water should be applied once every half a month, and the application should be carried out in the morning and evening. September is the fastest stage of thickening and growth of five-needle pine, so autumn fertilizer can be thickened (the concentration of fertilizer can be increased to about 25%) to promote multiple axillary buds, fewer flower buds, and sufficient nutrients for stem and branch growth. IO should stop fertilizing after the end of the month. In addition, fertilization depends on the weather conditions. For example, it is not suitable to apply fertilizer immediately if it is sunny for a long time; if it is sunny for a long time, it should be watered first, and fertilize after 2 Mel for 3 days.
5) light. Five-needle pine is a strong positive plant, usually the flowerpot should be kept in a dry, ventilated, sunny place to maintain, too wet and too shady are disadvantageous to its growth. The five-needle pine seedlings planted by Agricultural Bank of China for 1-2 years should be placed in the outdoor open air at all times except that they should be properly shaded in the hot noon in summer to prevent the needles from being overexposed to the sun. In this way, the five-needle pine bonsai has dense branches and leaves, thick green, high ornamental value and less diseases and insect pests.
6) Control of diseases and insect pests. The cultivation of five-needle pine, such as improper maintenance, is vulnerable to diseases and pests such as leaf blight, pine larch, pine tip borer, shell insects and so on. If leaf blight and pine leaf drop disease are found, the diseased leaves should be removed in time, and 50% methyl thiophanate wettable powder 800x solution should be sprayed. When pine tip borer, scale insects harm tip tips and feeding needles are found, 1000 times dichlorvos EC can be used to control them.
Rapid Prototyping of five-Needle Pine Bonsai
A pot of five-needle pine bonsai takes seven or eight years or decades of painstaking cultivation, can it be completed within three or five years? It's entirely possible. The methods and steps are as follows: the method of making small bonsai is as follows: in late winter and early spring, one-year-old black pine is selected, its trunk is tied into S shape with fine lead wire, and then the zigzag seed of the lower part of the mud is planted in acid mountain soil. during the growing period, the plants can reach 20 to 30 cm by applying low concentration of rotten human dung or urea two or three times. During the period from the Winter Solstice to Qingming Festival this year, the lead wire was released and the high connection was carried out. The scion adopts the apical bud of five-needle pine, and the orientation is determined according to the shape of black pine and the forming trend in the future. three to five terminal buds are grafted on the trunk of each plant, which is carried out by abdominal grafting, leaving the old leaves of black pine and removing the young buds in time, so as to supply the normal growth of five-needle pine scion. independent five-needle pine bonsai will be formed in the third year. During the period from the Winter Solstice to the Qingming Festival, the large-scale bonsai method went up the mountain to look for exposed roots and curved old black pine stumps. It was best to dig out the mud, trim the overlapping secondary branches, and fake plant them in the mountain or mud basin for commercial reception during the Spring Festival of the following year. The high grafting site is operated on about 2 cm above the black pine branch to correct the swelling of the interface. The scion of the five-needle pine is selected to be a strong branch or a stout main bud. If the branch is grafted high, it is fastened with plastic tape or adhesive tape at the interface, sealed with yellow mud to moisturize, and often sprays water to the leaf surface. An old post of black pine was grafted with five to ten scions, and the branches of black pine were trimmed in two to five years, and the development form of new branches of five-needle pine was slightly pruned, which could be fully formed in about five years. Five-needle pine likes sunshine and ventilation and adapts to acidic soil. Apply rotten cake fertilizer at the end of autumn. Need to dormancy in winter, put in the room around zero degrees, such as breaking the dormancy period, resulting in poor growth, will slowly die.
Management of five-needle pine bonsai in midsummer
Five-needle pine branches and leaves lush, vigorous green, Qiu branch needles, Rondo, appears elegant and simple, is a precious bonsai tree. In the midsummer season of every year, high temperature, strong sunshine and frequent precipitation are the most disadvantageous to the growth of five-needle pine bonsai, so the maintenance and management is very important.
Under moderate light, five-needle pine is a neutral plant, which can grow in sunny or shady places, but when maintained in sunny and well-ventilated places, the needles grow green and strong; in places with insufficient light and heat, needles grow thin and easy to wither and yellow. It is best to give five needles pine more than 5 to 6 hours of light every day, and maintain good ventilation conditions. But in the midsummer hot noon, in order to prevent the needles from getting too much sun caused by scorched leaves, shading and other measures can be taken, other times can allow them to fully accept the sun.
Control watering five-needle pine bonsai watering should pay attention to moderate, flower proverb "dry pine wet cypress", indicating that five-needle pine should be dry. The summer temperature is high, and the basin soil is easy to dry. Generally, the basin soil is watered once in the morning and once in the morning, and in the evening it depends on the dry and wet condition of the basin soil. In case of showers, it is necessary to cover the rain in time to avoid the loss of nutrients in the soil.
Regular fertilization is the key to raising five-needle pine, which can be combined with watering. The weather is hot from July to August, so 10% thin fertilizer and water should be applied once every half month. In addition, we should pay attention to the five-needle pine shade after fertilization, do not let the sun exposure.
It is not suitable to reshape the modeled five-needle pine bonsai. In order to maintain its inherent styling posture, it is necessary to reshape and trim every year. However, the pruning of five-needle pine should be carried out in its winter dormancy period, and must not be trimmed in the midsummer season, otherwise a large amount of pine resin will flow out of the wound, affecting the growth of five-needle pine.
How to raise five-needle pine bonsai well
To raise five-needle pine bonsai well, it is necessary to understand its habits and master its requirements for light, soil, moisture, fertilizer and so on.
Light five-needle pine can grow in landlords with plenty of light and shade. If planted everywhere in gardens, balconies and windows with plenty of sunshine and air, the needles grow green, short and robust. If you put it in a place with insufficient light and damp heat, the needles will grow thin and yellow easily. In the spring and autumn season, it can fully accept the sun. But in the summer inflammation tears at noon, to prevent the sun caused by scorched leaves, so it must be shaded. Usually shade with curtains or move the pot plants into the ventilated room, do not bask in the west for a long time, so as to avoid sunburn to death. Five-needle pine cold-resistant, winter can be placed in the outdoor sun, the temperature is kept at 0 ℃-15 ℃, should not be too high.
Five-needle pine prefers loam which is loose, fertile, well drained and acidic (PH value is between 5.5 and 6.5). Generally choose 25% rotten leaf soil, 25% mountain mud, 10% coke peat, 40% river sand or honeycomb coal slag, mixed with a little bone powder. If alkaline general garden soil is used, the leaves of the right pine will yellowing and fall off, and even cause plant death.
Moisture five-needle pine likes to dry and hate dampness, basin soil can be kept slightly moist. Otherwise, the pine leaves will turn yellow and wither gradually. In autumn and winter, the basal leaves will also turn yellow, which is a phenomenon of natural renewal of fallen leaves. Spring watering, usually 3mi every 4 days, but it depends on the weather of the day and the dry and wet conditions of the basin soil. During the rainy season, the air humidity is high, so watering should be reduced as appropriate. Sometimes it rains continuously, and you have to pay attention to buckle the water or put the potted plants in a ventilated place under the eaves. The temperature is high in summer, and the basin soil is easy to dry, so it is usually watered once in the morning and evening. The air is dry in autumn, and it is the growing season of five-needle pine. The soil is easy to dry and can be watered once every two days, but not too dry. At ordinary times, it is best to spray the foliar surface with clear water, which can not only cool down and remove dust, but also achieve the role of green Baoxiu. The amount of water watering is relatively reduced in winter. In order to prevent freezing, water must also be controlled. Only when it is too dry, the right amount of water should be watered.
Fertilizer fertilization is the key to raising five-needle pine well, which can be combined with watering, but it is based on the principle of "thin fertilizer and frequent application". It is usually watered with rapeseed cake, bean cake and bone meal. From March to June, fertilizer is applied every other half month, and the concentration of fertilizer and water is 15%. The weather is hot from July to August, so it is appropriate to apply about 10% diluted liquid fertilizer. September is a period of rapid thickening and growth of five-needle pine, so after late August, about 55% liquid fertilizer should be applied to promote its growth. Stop fertilizing after 11 / 11.
Before fertilization, the basin soil should be slightly dry and loosened to facilitate the full absorption of fertilizer. If the basin hurts the root. It is better to apply fertilizer in cloudy days and should not be applied in high temperature and strong light. On the second day after fertilization, the plants should be watered.
Saving the chlorosis of five-needle pine needles
First, we must carefully observe whether the needles of the five-needle pine are yellow or yellow. If the old leaves are yellow and the needles fall off with a slight movement of the hand, it means that the root system has not been damaged much, and the possibility of saving is greater; if the new and old leaves are yellow and not easy to fall off, it means that the possibility of saving is smaller.
Second, it depends on whether the skin of the branches has become wrinkled. If the epidermis has become wrinkled, gently peel off the epidermis of a branch with your hand. If there is no green and moisture, it indicates that the possibility of survival is small. If the epidermis of the branches has not become wrinkled, but the old leaves become soft and yellow, it is possible to save them.
Third, if it is caused by water shortage and drought, it should be watered immediately to moisten the basin soil, and it should not be watered enough. This is the key point. After waiting for 4 to 6 hours, pour water again, put it indoors for 3 to 5 days, and ventilate and change air. After 5 days, move to outdoor shade and spray vinegar mist of 0.5% for 4~6 times a day. After a week, gradually move into the sun under normal maintenance, and switch to water to spray needles, humidification can be.
4. If the needle becomes soft and green due to the dry and stuffy indoor air, lack of ventilation and long-term indoor (such as in the middle and late April in East China), the window should be opened to make the air convection, and 0.5% edible vinegar should be sprayed 3 to 4 times a day. After 3~5 days, move to outdoor sunshine for 2~3 hours, spray 4~6 times with about 0.5% edible vinegar solution, maintain for 5~7 days, the softened needles will be stable, and continue to grow new leaves. Some soft old leaves will harden and turn green again. After half a month, they can be put into a place with better light for normal maintenance. At this time, water can be used to spray 2 to 3 times a day, and the effect is obvious. Flower lovers might want to try it.
Why do five-needle pine needles sometimes turn yellow?
In midsummer and early winter, irregular yellowing often occurs in some needles in the middle of the branches, which is the general manifestation of normal metabolism of five-needle pine. However, some flower lovers cultivate five-needle pine every summer arrival, plant leaf tips turn yellow, late autumn after some leaf tips die, which will greatly affect the ornamental value. There are several reasons for this
1)Watering too frequently, or more rain in June every year, the basin soil is often too wet, coupled with poor drainage and ponding in the basin, causing hypoxia in the soil, causing rotten roots and yellowing needles.
2)In hot summers, water evaporates quickly and water is insufficient, resulting in scorched needles. If the sun is too hot, the pot soil is too dry, the five-needle pine will also appear at the tip of the needle tip charred, if the water continues; the plant will eventually die.
3)The five-needle pine is kept indoors for a long time, and the light and air are insufficient, which violates the habit of receiving light outdoors, or suddenly moves to the outdoor to encounter exposure, and the above situation will also occur. In order to avoid yellowing of pine leaves, corresponding preventive and rescue measures should be taken according to the above reasons.
Bonsai Osaka Pine (Golden Leaf Five-Needle Pine) Multiple Grafting
① Rootstock selection: selected after many years of cultivation, selection of beautiful shape, healthy growth of ten years to a hundred years of age can be.
(2) Scion selection: choose two-year-old branches from strong and disease-free Osaka pines as scions, and the best place is sunny.
(3) thinning branches: pruning and thinning branches of black pine on the basis of maintaining the original shape.
4. The scion incision should be equal to the rootstock incision length, the incision length is about 1cm, one side of the section is long, the other side is short.
5. Cut all the branches and parts of black pine with a sharp knife, cut into one-third of the xylem, insert the scion into the incision, and the cambium of each other must coincide with each other.
6. Use plastic tape to bind properly and tighten properly.
Let the needles of the five-needle pine bonsai be short and dense
Five-needle pine branches vigorous, four green, quaint posture, is an excellent bonsai species. How to make the needles short and dense is an important problem worth studying. After many years of practice, the author has accumulated some experience, which is summarized for the reference of bonsai lovers.
First, maintain sufficient light: five-needle pine likes sunshine, avoid shade. The five-needle pine potted plant is placed in a place with sufficient light. The needles are long and weak, and the internodes of the branches are longer. However, in summer, shade should be added to cool down slightly to facilitate growth. Because five needle pine cold tolerance, fear heat. Too high a temperature is bad for its growth.
Second, appropriate buckle water: five-needle pine drought resistance, avoid water wet, appropriate buckle water can shorten the needles, especially in the bud before and after a period of buckle water effect is very good. Too much watering, needles will grow, ponding easy to cause rot root death. It is better to dry the soil slightly. Of course, different seasons, different periods of watering should be different.
Third, control fertilization: five-needle pine barren resistance, not more fertilization. More fertilizer or thick fertilizer is easy to damage root system. High temperature season is not suitable for fertilization, serious cases can cause tree death. Control fertilization can shorten the needle; more fertilizer will lengthen the needle, usually in spring, each fertilization 1 to 2 times can be. Fertilization in the year of planting in the upper pot is even less.
Fourth, the pot should be small and shallow: five-needle pine flat coniferous species, drought resistance and barren. In general, the selection basin should be slightly small and shallow, avoid too large and too deep. Small pots are beneficial to short leaves, too large and too deep pots are easy to accumulate water and rot roots. Cliff type can use deep basin, basin bottom needs more broken tiles, so as to drain ventilation. Five-needle pine should choose simple and elegant purple sand pottery basin, basin shape needs to match the tree posture.
5. Picking buds in time: picking buds is an important means to control growth and maintain beautiful trees. Bud picking should be carried out every spring before bud elongation and needle placement. Remove 1/2 to 2/3 of the bud length. Sunny days are appropriate to facilitate wound healing. If the terminal buds are too dense, they can be picked more, and the buds can be picked less; the buds can be picked more, and the buds can be picked less; the vigorous growth can be picked more; the weak growth can be picked less or not. It is also necessary to decide to pick buds according to modeling needs. After many years of bud picking, the needles can be short and dense, and the tree shape is compact.
6. Reasonable shearing and binding processing: Five-needle pine has strong germination, flexible and elastic branches, pruning resistance, easy winding, winding and pruning are not only the needs of modeling, but also can control growth, shorten needles, and control growth. Shorten needles, make the tree more beautiful. Scissor binding modeling is suitable for winter to early spring dormant period, the wound needs wax, clay or black tape to prevent grease flow, otherwise it will affect tree growth, or even cause death. It is better to combine metal with brown wire.
Seven, the selection of short-leaf varieties: five-needle pine cultivation varieties are many, common have long-leaf five-needle pine, short-leaf five-needle pine, gold-leaf five-needle pine, silver-leaf five-needle pine, spiral leaf five-needle pine and so on.
The cultivation management of five-needle pine bonsai is luxuriant, vigorous and green, Qiu branch needles, convoluted, elegant and simple, is a precious bonsai tree. Every year in midsummer season, high temperature and hot, strong sunshine, frequent precipitation, the growth of pine bonsai is the most unfavorable, then the maintenance management is very important.
Moderate light five-needle pine is a neutral plant, in the sun or more shade can grow, but in the sun, air circulation of the local conservation, needle growth green and robust; in the lack of light and hot places, needle growth thin, easy to yellow. It is best to give five-needle pine more than 5 to 6 hours of light time every day, and maintain good ventilation conditions. However, at noon in midsummer, in order to prevent the needles from being exposed to excessive sun and causing scorched leaves, measures such as shading can be taken, and other times can be allowed to fully accept sunlight.
Control watering of five-needle pine potted plants should pay attention to moderate watering, flower proverb cloud "dry pine wet cypress", indicating that five-needle pine should be dry. Summer temperature is high, basin soil easy to dry, generally watering once in the morning and evening, and must be watered enough once in the morning, evening should be determined according to the dry and wet conditions of basin soil. During showers, it is necessary to cover the rain in time to avoid the loss of nutrients in the soil.
Regular fertilization is the key to raising five-needle pine, which can be combined with watering. July to August hot weather, appropriate to apply 10% thin fertilizer water, once every half month. In addition, pay attention to fertilization should be five needle pine shade, do not let the sun exposure. It is not suitable for shaping. In order to maintain its inherent modeling posture, it is necessary to reshape and prune it every year. However, the pruning of five-needle pine should be carried out during its winter dormancy period, and must not be pruned in the summer season, otherwise the wound will flow out a large amount of turpentine, affecting the growth of five-needle pine.
