For the newly bought cash cow, it is more appropriate to change the pot for the cash cow after one or two years. After 1-2 years of planting, the pot soil has gradually agglomerated and filled with old roots. Changing pots is beneficial to the growth of cash cows.
First, the cash cow for pot method
1. Don't change the new cash cow immediately. Let the soil in the original basin dry a little before changing it. Too wet soil replacement can easily lead to root damage, and in severe cases, the root system will rot.
2. Grasp the thickest branch of the outermost circle of the cash cow by hand, and grasp the lower end of the branch when harvesting to avoid scratching the leaves on it. Fix the pot and slowly pull the cash cow out of the pot.
You can't water the cash cow immediately after changing the pot. You must keep dry first. Let the injured part of the plant dry and heal before watering, pay attention to reasonable maintenance, and let the cash cow recover faster and grow better after changing pots.
Second, the maintenance method of cash cow
1. temperature: the optimum temperature for the growth of money tree is 20 ~ 32℃. Whether potted or planted in the ground, it is required that the annual average temperature change is small. In late autumn and early winter, when the temperature drops below 8℃, it should be moved to a well-lit room in time, and the temperature should be kept between 8℃ and 10℃ during the whole wintering period, which is more conducive to its growth.
2. Illumination: Money tree likes light and has strong shade tolerance, so direct strong light should be avoided, especially when it is exposed to the scorching sun after a long rain in Chu Qing in late spring and early summer, and baked naked for 5-6 hours around noon in summer, otherwise, it will easily lead to the young leaves that have just been pumped up being burned. We should create a sunny but cool environment for it.
3. Humidity: In order to preserve potted money trees, efforts should be made to create a humid and dry environment for them. For plants placed in the greenhouse, when the room temperature reaches above 33℃, water should be sprayed on the plants once a day. Because plants have strong drought tolerance, it is better to keep the soil slightly wet and dry, but occasionally watering too much water and fertilizer will also cause root rot. After the Mid-Autumn Festival, water should be reduced, or water should be sprayed instead, so as to help the newly picked young leaves to spend the winter safely. In addition, special attention should be paid to the pot soil in winter, which should not be too wet, and it is better to be dry. Otherwise, under the condition of low temperature, the pot soil is too wet, which is more likely to lead to root rot or even the death of the whole plant.
4. Fertilizer: Cash cows like fertilizer. In the growing season, the mixed solution of 0.2% urea and 0. 1% potassium dihydrogen phosphate can be applied 2-3 times a month, or the balanced fertilizer 20- 10-20(20-20-20) with a concentration of 200-250 ppm can be applied in combination with calcium nitrate. After the Mid-Autumn Festival, in order to make it overwinter safely, nitrogen fertilizer should be stopped and 0.3% potassium dihydrogen phosphate solution should be applied for 2 ~ 3 times continuously to promote the hardening and enrichment of young leaf shafts and newly-pumped leaves. When the temperature drops below 15℃, all forms of topdressing should be stopped to avoid fertilizer damage and root damage under low temperature.
Tip Don't water the cash cow immediately after changing pots, and keep it dry for a few days. Let the injured roots dry, and then water them after the wound recovers. After changing pots, we should pay attention to the management of temperature, light, water and fertilizer, which are directly related to the growth of cash cows.
What is the flower language of Qian Qian tree?
Cash cow flower language: turn money into treasure, become wealth.
Cash cow, also known as taro and Jinsong of American National Railway Passenger Transport Company. There is no main stem on the ground, and adventitious buds germinate from tubers to form large compound leaves, with fleshy leaflets and short, solid and dark green petioles; The underground part is a big tuber. Pinnate compound leaves are extracted from the top of tuber, and the axial surface is thick, with opposite or nearly opposite leaflets on the axial surface. The petiole base is enlarged and lignified; Each compound leaf has 6 ~ 10 pairs of lobules, with a life span of more than 5 years, and there are constantly new Ye Gengxin.
Cash cow originated in the tropical (grassland) climate zone with less rainfall in eastern Africa. I like warm and slightly dry environment, semi-cloudy environment, small annual temperature difference, and relatively drought-resistant, but I am afraid of cold, strong light, clay and water accumulation in basin soil. If the basin soil is impermeable to water, it will easily lead to tuber rot. The soil is required to be loose and fertile, well drained, rich in organic matter and acidic to slightly acidic. Strong germination, after cutting off the thick compound leaves, the top of the tuber will soon grow new leaves.
Cash cow is a popular indoor large-scale bonsai plant, especially placed in a wider living room, study and living room, with elegant and simple style and southern sentiment. It is a new generation of indoor foliage plants, which are beautiful, regular and world-famous. Its saplings grow slowly, which can be used as small pots or medium pots for cultivation and appreciation, or as large pots, with diversified choices.
Cash cow is suitable for many occasions and can be placed in spacious offices, new homes, living rooms, study rooms, balconies and other places. It can not only make people rich and auspicious, but also make the home environment look elegant and simple, with a southern atmosphere. It looks like a bunch of copper leaves. From a distance, it looks like a big bird with wings spread, which is very beautiful. You can see this vigorous plant in your daily work or life, which makes people more motivated and energetic to struggle.
How to maintain rich trees in cold areas
Rich trees brought into Xinjiang from the south are braided and shaped, and their crowns are intact. However, some branches are broken during transportation and loading and unloading, or the leaves turn yellow and fall off due to poor ventilation and water loss. As long as the flowerpot is not broken and the root system is not rotten, it will take more than a month to spit out the leaves and restore the crown by cutting off the broken branches and wilting shoots. Newly introduced plants should be applied with base fertilizer in the same year, and do not change pots. Generally, two or three months before transportation, the seedlings are put in a pot, most of the main lateral roots are cut off, and the mother soil is limited by the pot, so there is a process in which the seedlings grow slowly. Pour organic fertilizer and liquid fertilizer twice a month, such as chicken, sheep and horse manure infusion. You can also pour high phosphorus and potassium compound fertilizer solution to promote its rooting and development. No nitrogen fertilizer was applied in that year, and the white length of young branches was controlled to prevent the trees from slanting to the crown. Rich trees have strong adaptability to water. If you water outdoors or don't water indoors for more than ten days, there will be no floods and droughts that will cause the leaves to turn yellow. Water should be poured indoors every 3-5 days in summer and every 5- 10 days in spring and autumn. Outdoor full-light curing, watering once every 1-2 days, and frequently spraying blades to wash dust. Looking at the room temperature in winter, the soil in the basin is slightly wet. If the room temperature is around 12℃, you can water it once a month.
This tree species is resistant to both shade and sun, and has strong adaptability. In the outdoor full sunshine environment, the leaves are short and wide, dark green, the crown is full, and the stem base is thick. Under long-term weak light, the branches are thin, the petiole is drooping, and the leaves are light green. Do not change the yin and yang position of the basin in management, especially from indoor to outdoor, in order to adapt to the lighting process. Otherwise, the leaves will get sunburned easily. From the end of April, when the weather is clear at noon, move the basin out of the outdoor or balcony and directly expose it to the sun 1-2 hours, and the time will be gradually extended until it is completely illuminated. Even in summer, it doesn't matter, the leaves won't be damaged by high temperature.
Rich trees like warm environment, are not hardy, and adapt to the growth temperature 18-30℃. The high temperature period in summer is a fast-growing stage, so it is necessary to strengthen the management of water and fertilizer. When the temperature is as high as 35℃, water should be sprayed around the basin and on the leaves to increase the humidity. The most ideal way is to put the basin in lawns, flowers and other plants, or put several containers such as pots and cups on the surface of the basin to let the water evaporate naturally and adjust the microclimate. In spring, leave the room at the end of April or early May and put it in the lee of the sun. In autumn, according to the weather changes, people usually go indoors for the winter in September. The enclosed balcony can be extended to the end of 10. In the dead of winter, as long as the room temperature is kept above 18℃, there is plenty of sunshine, and scientific watering and fertilization will make it grow as usual, spreading its leaves and pumping branches. When the room temperature is lower than 8℃, it is humid, dry and unventilated, and the leaves are prone to water stains and fall off in bronze. When the temperature is lower than 3℃, all the leaves will fall off, and the tender branches will lose water and dry up. In severe cases, the whole plant will die in spring.
Rich trees grow faster and have developed roots. Pots should be changed every two years, in late autumn and early spring. Do not water the pots before changing them until the soil shrinks and the pots are separated from the walls. Beat the drum on the wall and bottom of the basin and take out the whole plant. If it is difficult to take out, you can gently inject water along the gap in the basin wall, let the water penetrate into the bottom of the basin, and then shake it back and forth to take out the roots. Never dig out the pot soil, because it is different from a single plant, the main root is in the middle, many plants are clustered, and the main root and lateral root are staggered. Improper excavation will hurt roots and loose braids. If the newly bought bonsai plants grow vigorously and the pots are too small, they can also be changed in July and August by using the semi-dormant state of the plants at high temperature. Do a good job of careful operation, so that the mother soil is not loose, and after planting, water is poured enough, which will not affect the growth. This tree species has strict requirements on basin soil and likes acid sandy loam and humus with good drainage. 60% of vegetable garden soil or humus soil, 30% of human and animal dry manure powder, and 20% of river sand or granular slag are selected as nutrient soil and mixed. Spraying 0.5% ferrous sulfate and 0.3% potassium dihydrogen phosphate solution at the same time. It is best to use pure forest humus when conditions permit. When planting, properly trim the roots, remove too many fibrous roots wrapped around rotten roots, and shake off some hardened original soil. Divide the basin into 5 cm nutrient soil (no base fertilizer) and put a few horseshoe pieces. The soil buried under the stem base is not easy to be deeply planted, and the swollen and round stem base is exposed to the basin surface. After planting, water it, put it in the shade to slow down the seedlings, and turn it into normal management in about three weeks.
Overall pruning determines the pruning intensity according to the crown shape. The long branches that affect the crown shape are cut from the branches 3 cm above the leaf nodes. Remove sprouted branches from the trunk of dead branches and yellow leaves at any time. The top branches are all wilted, which can be pruned from appropriate parts to promote re-germination. This tree species grows 2-5 layers of palmately compound leaves from the top every year, and the lower old leaves naturally fall off every two years 1-3 layers. Due to environmental impact and improper management, it also falls off every year. According to its physiological characteristics, the lower wheel space and trunk are woven one after another. Family plants are not easy to be too high, and they are easy to manage in the range of 1.5-2 meters. If the height of the plant is too high, the stubble can be leveled to make it grow lateral branches, increase the crown and show its charm. For the crown with short leaves, many impellers and rich leaf curtains, we should carefully untie the tail of the crown to make it loose into 5-7 palm-shaped Ye Zhan spaces independent of the umbrella shape, so as to achieve a fluffy crown.
Rich and noble trees have strong resistance, and we have raised them for several years, and no pests and diseases have occurred. Spraying carbendazim, bacitracin and 8% dichlorvos EC in summer. Potted plants have not seen flowers or fruits for several years.
How to raise rubber trees, rubber tree families and their conservation methods
Some netizens asked how to raise rubber trees and how to care for rubber trees planted at home. The following is a brief introduction: rubber trees like high temperature and humidity, sunny environment, shade-tolerant but not cold-resistant. Hevea brasiliensis mostly adopts cutting and high pressure propagation. Cutting propagation is relatively simple, easy to survive and grow rapidly in high temperature and high humidity environment.
Hevea brasiliensis originated from Indian and Malaysian, and is now cultivated all over China. Rubber tree, also known as Ficus and Rubber Fruit, is an evergreen woody foliage plant of Ficus in Moraceae.
Rubber tree leaves are large, thick leathery, shiny, round to rectangular; The surface of the leaves is dark green, and the back of the leaves is light green, which is initially wrapped outside the terminal bud. After the new leaves are stretched, the stipules fall off, leaving traces of stipules on the branches. Its mosaic varieties have yellow and white patches on the green leaves, which is more beautiful and pleasing to the eye.
Rubber trees are often used for cutting and high-pressure propagation. Cutting propagation is simple, easy to survive and fast to grow. Generally, pruning is combined in late spring and early summer. Select annual lignified middle branches as cuttings, cut off the lower leaves, close the upper two leaves and bind them with plastic, or cut off the upper leaves for half a week to reduce water evaporation; In order to prevent the incision from losing too much milk and affecting the survival, plant ash should be used to smear the wound in time; Cutting the treated cuttings into seedbeds based on river sand or vermiculite; Keep the bed high humidity after insertion, and often sprinkle water on the ground (but don't sprinkle water) to improve the air humidity. Under the temperature of 18-25℃ and semi-shading, rooting takes about 2-3 weeks. It is also convenient to use high pressure at home and the success rate is high. Selecting biennial branches under high pressure, firstly girdling branches with the width of 1- 1.5 cm; Then wrap wet moss or peat soil around the wound, and finally wrap it tightly with plastic film, and wrap it at the upper and lower ends; 1-2 months later, the rooting branches can be cut off and put into the pot.
When rubber trees are potted, humus soil 1 serving, garden soil 1 serving and river sand 1 serving should be used as culture soil, and a small amount of base fertilizer should be added. It grows very fast in a high temperature and humid environment, and a leaf can be produced every 5- 10 days. In the meantime, we must ensure adequate fertilizer and water. Generally, liquid fertilizer or compound fertilizer should be applied 1-2 times a month, while maintaining high soil moisture. After autumn, gradually reduce the number of fertilization and watering to promote plant growth and enrichment, which is conducive to wintering. Rubber trees like strong sunlight, and they should be planted in the sun from spring to autumn throughout the growing season, and also under strong light in winter; However, it is also shade-tolerant, and it is also better to cultivate in indoor weak light. In addition, in order to make the plant grow evenly and ensure a good plant shape, when the seedlings grow to a height of 50-80 cm, they are cored to promote the germination of lateral branches; After the lateral branches grow out, select 3-5 branches, and then cut them short once a year, and after 2-3 years, you can get a large plant with complete plant type, roundness and fullness.
The leaves of rubber trees are thick and beautiful, and the leaves are wide, beautiful and shiny. The red terminal bud is like a cloud, and the stipules are like red tassels hanging upside down after splitting, which is quite charming. It is a famous potted foliage plant with high ornamental value. Rubber trees are sunny but resistant to shade, and have strong adaptability to light, which is very suitable for indoor landscaping. Small and medium-sized plants are often used to beautify the living room and study; Medium and large plants are suitable for layout on both sides of the foyer and the center of the lobby of large buildings, which are magnificent and can reflect the tropical phoenix light.
Prevention and control of anthrax
1. Combined with pruning, diseased branches, diseased leaves and dead branches are removed to reduce germs.
2. Pay attention to light transmission and ventilation on weekdays, don't place it too close, and choose disease-free plants to prune and propagate seedlings.
3. Spraying 1% Bordeaux solution after new buds grow in early spring. Spray 1% bordeaux mixture or lime-sulfur mixture with Baume degree of 0.3 or 0.5% potassium permanganate every half month from June to September. In addition, spray 500-800 times solution of 50% wettable powder such as thiophanate, carbendazim and chlorothalonil in the early stage or early stage.
Prevention and treatment of gray spot disease
September -65438+ 10 is heavier, with small gray spots, which expand into irregular shapes, gray inside and dark brown edges, and the leaves crack and appear black particles in the later stage. Bacteria invade from the wound, and 50% carbendazim 1000 times or 70% thiophanate-methyl 1200 times can be sprayed at the initial stage of the disease.
