Explain the cultivation methods and matters needing attention of green plant Pittosporum.

Pittosporum is an evergreen shrub or small tree, also known as Qilixiang and Baozhuxiang, which is a common green plant in our life. The overall appearance of Pittosporum is umbrella-shaped, with white flowers, fragrance and high ornamental value. The most important thing is that Pittosporum has strong vitality and is easy to plant and survive. We don't have to worry about planting failure. Many parks or roads will be decorated and afforested by planting pittosporum. In southern China, activities and venue arrangements will be decorated with Pittosporum in front of the venue or podium. Because the branches and leaves of Pittosporum are evergreen all year round, there is no need to worry about being lifeless even in cold winter. Let's take a look at the breeding methods and precautions of Pittosporum!

Introduction to growth habits of Pittosporum

Strong adaptability to the climate, cold resistance, but also quite resistant to summer heat. South of the Yellow River basin, you can safely overwinter in the open field. It has strong adaptability to soil and can grow normally in clay, sandy soil and mild saline-alkali soil. It has strong resistance to sulfur dioxide, hydrogen fluoride, chlorine and other toxic gases. It also has strong adaptability to light and is more resistant to shade and scorching sun, but it grows best in semi-shade. The optimum growth temperature is 15 ~ 30℃, and it can withstand freezing temperature in cold but not frozen room in winter, but the lowest temperature at night should be kept above 13℃, so it grows well.

Introduction of Propagation Methods of Pittosporum

Pittosporum is propagated by sowing or cutting. The capsule ripens in 10 ~ 1 11and is sown in the middle of March of the following year. The germination rate of seeds by drilling method is about 50%. The growth of seedlings is slow. Generally, it takes 2 years for seedlings to grow in pots, and it takes 3-4 years for seedlings to take out soil balls from nurseries for planting. Cutting before new leaves germinate in early spring, cutting off 1 ~ 2-year-old shoots, cutting them into 15 cm long, inserting them into a wet sand bed, spraying water for moisture preservation, rooting in about 20 days, and moving them into a nursery for cultivation in about 1.5 months. 2-3-year-old shoots can be planted in pots or out of the nursery. In normal management, we should pay attention to maintaining tree shape, properly watering in drought and applying 1 double base fertilizer in winter.

Introduction of seedling raising methods and matters needing attention of Pittosporum rubrum

1. Upper basin: The upper basin of Pittosporum needs to be planted in a deep basin, and a circle of hard plastic cloth with a height of 5-8 cm is added on the upper part of the inner edge of the basin, and the bottom of the basin is padded with broken tiles. The root can be raised correspondingly when the pot is put, and the pot soil is slightly lower than the plastic ring, so that deep pot shallow planting will not affect the survival.

2. Lighting: Pittosporum has strong adaptability to light and can be placed outdoors in summer. If possible, it can be placed in the shade of flowers. Strong light is harmless to plants.

3. Watering: Pittosporum consumes a lot of water in summer, so water it frequently. If the temperature is low in winter, the amount of watering will be reduced accordingly.

4. Fertilization: Fertilize Pittosporum fortnightly during the growth period, and do not need to spin fertilizer in other periods.

5. Change pots: young potted pittosporum will change a pot every year, and adult plants will change a pot every 2-3 years. The flowerpot is mixed with 1/3 humus and 2/3 clay or loam. When changing pots, the dead roots should be cut off and new culture soil with more organic matter should be added to the pot soil.

Cultivation methods and matters needing attention of banyan tree

Banyan bonsai is one of the choices for many flower lovers to cultivate green plants in recent years. Its simple, desolate and vigorous style really makes people like it, simple and tasteful. But many people don't know how to raise banyan trees. Many people have problems when planting banyan trees, and even die. Now tell everyone that banyan trees are best placed in a well-ventilated place. Soil requirements: The general requirements for cultivating soil in banyan bonsai are loose, breathable and sour black stone silt, river sand, building stone powder and cinder. And these culture soils are easy to obtain.

Watering requirements: banyan bonsai can cover the roots with cultivated soil, and it is advisable to plant trees about 3 inches deep. After pouring the root water thoroughly, put it in a cool and leeward place for maintenance, and cover the ground with a cover. Watering can be decided according to the weather. Keep the culture soil moist and free of water. Too much waterlogging can easily lead to root blackening and necrosis. Long-term waterlogging of surviving banyan trees is easy to cause only long roots and no branches. Trees will not die if they are not watered for two or three days in dog days, but once they are watered, their leaves will wither and fall off, which will affect their growth. Therefore, water management should be dry and wet.

Fertilization requirements: Ficus microcarpa is a tree species that likes water and fertilizer, and is drought-tolerant and moisture-tolerant. After the stump enters normal care, the decomposed human and animal manure or cooked cake fertilizer is used as topdressing, and the topdressing outside the root is 1-2 times a day. When transplanting or changing pots, cooked chicken manure, bean cake, bone meal and culture soil can also be mixed as base fertilizer. Sufficient fertilizer will make the branches grow fast and thick, and they can be pruned several times a year, thus shortening the culture period.

Lighting environment: In banyan bonsai, it should be placed in a ventilated and light-transmitting place with a certain space humidity. Insufficient sunshine, poor ventilation and lack of certain space humidity will make plants yellow, lead to diseases and insect pests, and even die.

Pruning points: it is not advisable to prune blindly, let it germinate first, and it is best not to prune the old piles just planted in the first year. If there are too many branches, they should be pruned between March and April. Cut off a few messy branches at a time and cut them several times. Once cut too much, it will affect the growth of roots and the whole stump.

Pruning points: Pruning is a very important process when banyan piles become banyan bonsai. In the first year, cultivate its roots, raise its essence, and only smear the wrong buds. In the second year, cut the branches after they grow thick and woody. It is advisable to cut it once a year, mainly by cutting and supplemented by binding. Cut the branches twice when they grow vigorously, and cut them again after they grow vigorously. Over and over again, if properly trimmed, a good bonsai will appear in front of you within four years.

Pest control: Pests and diseases: The damage or decay of root system is also easy to shed leaves, but it is difficult to find because the root system grows in the soil. Root rot is very common because of long-term failure to change pots or improper fertilizer and water. It is best to check the roots, and trim the dead roots, weak roots and injured roots properly without damaging the roots. Soak it in a growth agent and plant it in a pot. In addition, the roots of banyan trees are prone to root rot or nodule disease caused by various bacteria and fungi, so proper attention should be paid to spraying drugs for prevention and control. The pests of banyan mainly include aphids, red spiders and mites. Spraying 500ppM omethoate or 1000 times 50% sulfinate wettable powder on the leaves. It is also effective to use 0. 1% washing powder water or essential oil water.

Matters needing attention in banyan cultivation

1. Improper watering: When watering banyan trees, we must adhere to the principle of not watering them, but watering them thoroughly. Drying here means that the surface of the basin soil is dry, not that the basin soil is completely dry. Of course, even if it is dried in Toya, it will not cause great harm to the banyan tree in a short time, because the leaves of banyan tree are thick and small, which has certain drought resistance.

2. Improper fertilization: Ficus microcarpa needs thin fertilizer and diligent application, so as to avoid applying high-concentration chemical fertilizer or organic fertilizer that has not been decomposed by fermentation, otherwise it will cause fertilizer damage, and the light leaves will fall off and the heavy ones will die.

3. Insufficient illumination: Banyan trees grow well in an environment with sufficient illumination. If you can shade 30-50% in the high temperature period in summer, the leaves will be greener, but it is best not to shade when the temperature is lower than 32℃ to avoid the leaves falling off.

4. Pests: The pests that cause the defoliation of banyan trees are mainly red spiders and scale insects, although there are thrips. This kind of insect only sucks juice by rolling leaves, which is less harmful than the above two kinds. Thrips are easy to control and can only be removed and destroyed. However, spiders are relatively small, and the general damaged part is the back of leaves, which is caused by poor ventilation and dry air. The whole plant can be washed with water and sprayed with acaricide, such as acaricide and acaricide. The most harmful parts of scale insects are stems and petioles. , different sizes and colors, round and oval, generally motionless, but it is harmful and needs to be prevented in time. Brush it off with a toothbrush or wipe it clean with a rag, spray 0.2% washing powder and essential oil solution, or spray pesticides such as methidathion, all of which have good results.

Shower Valley Tip: Ficus is a typical strong positive tree species. In the process of cultivation, if the sunshine is insufficient, it will lead to defoliation.

Explain indoor five-color plum cultivation methods and matters needing attention.

Five-colored plum is an evergreen shrub, also known as Shanda Dan and Ruyi Grass. Five-colored plum is a very strange plant with rich colors, and some varieties will change color in one day, which is very beautiful. The flowering period of five-color plum is generally from mid-late April to mid-February of the following year, but it can be seen almost all year round due to the influence of climate and temperature, which is of great ornamental value. Five-colored plums are usually planted in the yard at home, and now there are potted plants in the room. Let's take a look at the breeding methods and precautions of five-color plums!

Basic information of five-color plum:

Five-color plum can reach 2 meters high, with strong smell and short hair. Stems and branches usually have downward hooks and thorns. Leaves opposite, ovate or oblong-ovate. Flowering in all seasons, the inflorescence is axillary, the corolla is saucer-shaped with 4 ~ 5 cracks, and the colors are rich and varied, including red, pink, yellow, orange and white. Some flowers are yellow or pink at first, gradually turn orange or orange, and finally turn red, so they are called five-color plum and seven-color flower.

Breeding value of five-color plum

1. Ornamental: Five-color plum trees are full of flowers, gorgeous all year round, with long flower viewing period and gorgeous colors, such as red, orange, yellow, pink and white. Some flowers are yellow or pink at first, gradually turn orange or orange, and finally turn red. The flowers are small and unique, very beautiful and have certain ornamental value.

2. Bonsai: Five-colored plum branches are soft, suitable for making various forms of bonsai, which can be processed into different forms of bonsai such as single-dry, double-dry, water-facing, oblique-dry, etc., and are also very suitable for home furnishings. Because of the large leaves, the crown is often natural and can also be deliberately tied into a circle.

Introduction of breeding methods and matters needing attention of five-color plum

1, fertilizer and water: loose and fertile sandy loam is suitable for potted plants, and the requirements are not strict. Applying decomposed liquid fertilizer every 10 day, combined with watering, and spraying 3% urea twice every 10 day can make the leaves thicker and greener.

2. Sunshine: Five-color plum likes sunny environment, and it can be placed in sunny outdoor places during the growing season. Even in midsummer, it is not necessary to shade the sun, but it requires good ventilation. If the light is insufficient, the plants will grow white, the stems and branches will be slender, and the flowers will be scarce, which will seriously affect the appreciation.

3. Pruning: Five-color plums grow rapidly. When planting, the branches and leaves that affect the shape should be cut off in time to keep the tree beautiful. After each flowering, the long shoots should be cut short, and the plants should be cut short again in late autumn and early winter before entering the room. The branches of that year should be cut short appropriately. In winter, plants can grow and bloom normally when they are moved to the sunny place indoors. If the room temperature can be maintained above 15℃, they should be watered, fertilized and pruned appropriately.

Cultivation methods and matters needing attention of purse

Money bag is a very common foliage plant, which is easy to take care of and suitable for indoor potted plants. Many flower lovers need to know the cultivation methods and precautions of purse. This article will talk to flower friends about money pockets as some key points of maintenance, hoping to help them.

1, the cultivation method of purse

Money bags like warm, humid and sunny environments. Resistant to semi-shade, not cold, afraid of drought. Can be placed in a brightly lit room for a long time at home. If you can see the sunshine indoors for a few hours every day, it will grow more vigorously. Pay attention to avoid direct outdoor sunlight in summer. During the growing period, keep the basin soil moist without water accumulation, and often spray the plants with water close to room temperature to increase the air humidity and make the leaves fresh.

What needs to be noted here is that we must know the humidity of the basin soil and don't water it blindly according to the time. If the basin soil is not very dry, don't water it, just spray water to keep the humidity. Many flower friends' money bags are hung up because they don't check the actual situation and water them blindly.

When the purse is in a normal state, thin fertilizer can be applied once every two weeks or so, and fertilization can be stopped after September to make its new branches mature, which is beneficial to overwintering. In winter, put it in a sunny place indoors, reduce watering appropriately, and keep the temperature above 12℃, otherwise, a large number of leaves will fall off or even plants will die because of the low temperature.

The purse should be changed every two to three years. Potted soil should be loose and fertile, rich in humus, and well ventilated. 1/3 river sand can be added to humus soil or peat soil, and a small amount of decomposed chicken manure and cow dung can be mixed as base fertilizer.

To reduce evaporation, 1 ~ 2-year-old branches can be cut. The cutting length is about 10 cm, and most leaves are removed. Under the condition of 20℃ to 25℃, it can maintain high air humidity and take root in 4 to 6 weeks.

2. Precautions for daily maintenance of purse

In fact, the precautions mentioned here are not only applicable to money bags, but also to other potted plants with leaves. Here, I will simply talk to the flower friends. One is to pay attention to ventilation. Indoor maintenance is different from outdoor maintenance. If the indoor ventilation is not good, it is very easy to cause the purse to wither and die slowly.

Another problem is watering. As I said before, we should pay attention to the actual situation when watering. In particular, some flower friends have big pots of money, which are very big and deep. They are often watered once and will not dry for a long time. In this case, watering is not recommended, because the soil in the flowerpot is too wet, which will lead to root problems and eventually death. So when watering, try to water the basin when the soil is dry, and spray water at ordinary times.
