The difference between loose-tailed sunflower disease and insect pest control and Phoenix-tailed bamboo

Loose-tailed sunflower looks very similar to bamboo, but loose-tailed sunflower is also going to get sick. How to control the diseases and pests of loose-tailed sunflower? What is the difference between Phyllostachys pubescens and Phoenix tail bamboo?

Pest control of sunflower:

Leaf spot disease, leaf tip and leaf edge are the most vulnerable, resulting in dry curl, the initial stage of the disease with 50% carbendan wettable powder 500 times liquid spray control. In addition, it may be harmful to scale insects and can be sprayed with 1500 times of omethoate EC. In the summer high temperature season, the plant should be placed in indoor scattered light or under the shade to avoid direct sunlight. In the northern area in late September, the outdoor temperature gradually decreased, the potted flowers placed outside should be moved into the place with sufficient indoor light in time, pay attention to heat preservation and cold protection, and the indoor temperature should not be lower than 10 ℃. During this period, attention should be paid to reducing the number of rehydration, so as to avoid low temperature, high humidity and rotten roots and yellow leaves.

1. Leaf blight is a common disease caused by fungal infection, which has a great impact on the growth of loose-tailed sunflower, which will dry up the leaves in light cases and lead to the death of the whole plant in severe cases.

Prevention and control methods:

Strengthen ventilation, avoid rain and spray during the onset of the disease; cut off the damaged branches and leaves in time to prevent further infection, and apply daconine ointment to the wound after pruning; if there is a disease, it can be sprayed with 1000 liquid of 70% methyl topzine or 75% chlorothalonil, once every 7 to 10 days, 3 to 4 times in a row, which can effectively control the disease.

If the environment is dry and poorly ventilated, red spiders and shell insects are easy to occur, so it should be sprayed with 800 times omethoate regularly.

2. Prevention and cure of root rot.

The leaf tip and leaf edge of loose-tailed sunflower appear dry coke during the growth period, the main reasons are:

1, the air is too dry loose tail sunflower likes the higher air humidity, when the air is too dry, it will cause the focal tip and edge of the leaf. Water should be sprayed on the leaf surface and the surrounding environment 3 or 4 times a day throughout the growth period to increase air humidity. But stop watering after dormancy.

2. The sunshine is too strong

Loose-tailed sunflower likes the semi-overcast environment from May to September, and there will be some phenomena such as leaf yellowing, focal tip, focal edge and so on in direct sunlight. During this period, it should be placed under a shade or under a big tree to avoid direct sunlight.

3. The basin soil is too dry.

Loose-tailed sunflower needs to provide sufficient water during its growth. When the basin soil is dry for a long time, because the growth of the plant does not get enough water, the leaf tip and leaf edge will dry.

4. the basin soil is too wet.

It is not that as long as there is water in the basin soil, plants can absorb and use it. When the basin soil is too wet, it affects the respiration of the plant root, which affects the water absorption of the root system, and leads to the lack of water in the plant, which leads to the focal tip and edge of the leaf.

5. Excessive fertilization

Excessive fertilization will cause the reverse osmosis of plant root cells and make the plant lose water. When the degree is light, it will lead to the focal tip and edge of leaves, and in serious cases, it will cause rotting root death. The growth stopped at 10 ℃ and entered the dormant period. When the temperature is less than 6 ℃, it is necessary to move into the room to keep warm, and the room temperature should be kept above 8 ℃. After moving into the room, it should be placed in a place with light, and those with air conditioners and other heaters in the room should stay away.

The difference between loose-tailed sunflower and Phoenix tail bamboo:

Sunflower with loose tail:

Also known as yellow coconut, Aoi Murasaki, is the palm family, sunflower genus evergreen shrubs or small trees, its roots are smooth, generally yellowish green, leaves are relatively smooth and slender, of course, a scattered tail.

It likes the warm, moist, ventilated semi-shady environment, not resistant to cold, can be seen everywhere in the south, the north belongs to indoor green plants, listen to shade-resistant, exposure is not!

Phoenix tail bamboo:

Filial piety bamboo is a variant of bamboo, it becomes smaller, shorter, green leaves whirling, of course, more elegant, a string of leaves is like the tail of a Phoenix, the leaves are very small, ornamental is still good!

Seeing this Phoenix tail bamboo, I know that it is not a Phoenix tail sunflower, it is really an ornamental bamboo, not a palm plant.

It generally grows in the south of our country, like warm and humid welcome, bright light on the line, but also more shade-resistant, but not cold-resistant, do not like exposure, the maintenance of basin soil must be well drained, sandy soil will be fine!

It is easy to die when the temperature is below 0 degrees in winter. it looks very fresh and elegant, and it is still a great small bonsai in the courtyard and indoor.

The disease and pest control of loose-tailed sunflower is introduced here, and the difference between loose-tailed sunflower and Phoenix tail bamboo is also introduced. Have you made a clear distinction between the two?

The difference between loose-tailed sunflower and Phyllostachys pubescens Culture method of loose-tailed sunflower

Phyllostachys pubescens and sunflower are common small landscape plants, but people often confuse the two. The following is about the difference between loose-tailed sunflower and Phoenix-tailed bamboo, as well as the breeding method of loose-tailed sunflower.

The difference between loose-tailed sunflower and Phoenix-tailed bamboo

Sunflower with loose tail

Loose-tailed sunflower, also known as yellow coconut, Aoi Murasaki. Tufted evergreen shrubs or small trees of the genus Palmaceae. The stem is smooth, yellowish green, without burr, covered with wax powder when tender, with obvious leaf marks and ringed striations. The leaf surface is slippery and slender, pinnatifid, long 40~150cm, petiole slightly curved, apex soft.

Inflorescences born under leaf sheath, paniculate, about 0.8 m long, with 2-3 branches, branched inflorescences 20-30 cm long, 8-10 rachilla, 12-18 cm long; flowers small, ovoid, golden, spirally inserted on rachilla; male sepals and petals with 3 sepals and petals with striped veins, stamens 6, anthers ±T-shaped. Sepals and petals of female flowers similar to those of male flowers, ovary 1-loculed, with short styles and thick stigmas.

The fruit is slightly turbinate or Obovate, about 1.5-1.8 cm long, 0.8-1 cm in diameter, yellowish when fresh, purplish black when dry, exocarp smooth, mesocarp with reticulate fibers. The seed is slightly Obovate, the endosperm is uniform, there is a long and narrow cavity in the center, and the embryo is lateral. Flowering in May and fruiting in August.

Phyllostachys pubescens

The plant type is short, the green leaves are fine and whirling, and the charm is unrestrained, just like the Phoenix tail. The branch is slender, and the upper end of the bamboo pole is thin because of its luxuriant branches and leaves. The branches are dense, slender and curved. Leaves small, about 3cm long, often 20 arranged on both sides of the branches, like pinnate. Bamboo stalks and branches that are solid or nearly solid are called "Guanyin bamboo", while hollow ones are called "Phoenix tail bamboo".

Phoenix tail bamboo is native to southern China. Like warm, humid and semi-shady environment, cold tolerance is poor, not resistant to strong light exposure, afraid of waterlogging, suitable for fertile, loose and well-drained loam, winter temperature is not lower than 0 ℃. Phyllostachys pubescens has dense clusters of plants, short stems and beautiful branches and leaves, which can absorb formaldehyde and purify the air. It is often used in potted plants, decorated with small courtyards and rooms, and also used to make bonsai or as a low hedge material.

Difference

Loose-tailed sunflower and Phoenix tail bamboo belong to different species, loose-tailed sunflower belongs to shrubs, its highest height can reach 7 or 8 meters. Its stem is very smooth, often golden yellow, its leaves are slender and ring-shaped, the longest can reach 150cm, the leaves are bright green.

Phyllostachys pubescens is a ligneous plant, its main stem grows densely, its stems are hollow, its highest height can only reach about 3m, and its leaves are fine and whirling, and some leaves are as thin as needles and shaped like Phoenix tails. Its branches and leaves are very luxuriant and often bend the stem to form a natural drooping state.

Culture method of loose tail sunflower

I. Propagation methods

1. Sowing method

Most of the seeds used for sowing and reproduction are imported from abroad, and it is difficult to collect mature sunflower seeds at home. Pot sowing is commonly used, the thickness of the covered soil is twice as thick as the seed, and the potted soil is kept moist. When the seedlings are 8-10 cm high, they can be planted separately.

2. Split-plant method

Loose-tailed sunflower can propagate all the year round, around April, combined with changing pots, select the plants with many tillers in the base, remove part of the old basin soil, and divide it into several clumps from the base joint with a sharp knife. The wound needs to be disinfected with plant ash or sulfur powder. Each clump should not be too small, there must be 2-3 plants, and retain the root system, the newly planted sunflower, because the root system is not yet well developed, should avoid exposure to strong light for a long time. Water properly and spray water to the leaves several times a day to keep the leaves moist. Curing at 20-25 degrees Celsius, the recovery is faster. Generally, it can become a potted commodity after 1-2 years of maintenance. Otherwise, the growth of loose-tailed sunflower is slow after ramet, and it affects the ornamental. After planting, it was placed in a high humid temperature environment, and often sprayed with water to facilitate the recovery of growth.

Aquaculture management

1. Humidity

Loose-tailed sunflower is native to the tropics, likes high temperature environment, and has strict requirements on winter temperature. When it is lower than 10 ℃, it grows slowly and begins to enter semi-dormant or dormant state; when it is below 5 ℃, it can not survive the winter safely; in summer, it can be tolerated when the temperature is above 35 ℃, but its growth will be temporarily hindered. The most suitable growth temperature is 18-30 ℃.

2. Lighting

Loose-tailed sunflower is not strict with light, likes plenty of sunshine and can withstand half-shade, but grows better when there is enough light.

3. Fertilizer and water

For potted sunflower, in addition to adding organic fertilizer when potting, proper fertilizer and water management should be carried out in the usual maintenance process. Spring, summer and autumn, these three seasons are the peak growth season of sunflower, the interval period is about 1-4 days, the interval period is shorter in sunny or high temperature, and longer or unwatered in rainy or low temperature. In the winter dormancy period, the main work is to control fertilizer and water, the interval period is about 3-7 days, the interval period is shorter in sunny or high temperature, and longer or unwatered in rainy or low temperature. For loose-tailed sunflower planted in the ground, fertilizer and water were applied 2 times and 4 times in spring and summer: first, a small ditch was separated at 30: 100 outside the root neck (the larger the sunflower, the farther away from the root neck), the width and depth of the ditch were 20 cm. The ditch is sprinkled with 25-50 jin of organic fertilizer, or 1-5 two-grain compound fertilizer (chemical fertilizer), and then poured with water. After the beginning of winter, before the beginning of spring, fertilize again according to the above method, but do not need watering.

4. Pruning

Loose-tailed sunflower does not need to be pruned, its beauty lies in the graceful leaves, as pure and beautiful as a girl, and the shell wrapped in the root is fine if you don't like it, otherwise you don't have to peel it off, because it will fall off naturally at a certain time. Diluted compound fertilizer can be used if there is a large number of loose-tailed sunflower.

III. Pest control

1. Leaf spot

Loose-tailed sunflower leaf tip and leaf edge are the most vulnerable, resulting in dry curl, the initial stage of the disease with 50% carbendan wettable powder 500 times liquid spray control. In addition, it may be harmful to scale insects and can be sprayed with 1500 times of omethoate EC.

2. Whitefly

Can be used Caltex dipterex 200 times liquid spray control, loose tail sunflower leaves and roots should be sprayed. If you can always maintain good ventilation, loose-tailed sunflower is not prone to whitefly. If the environment is dry and poorly ventilated, the harm of red spiders can also occur, which can be prevented by spraying 3000-5000 times diluent of 20% wettable powder.

The difference between loose-tailed sunflower and Phoenix-tailed bamboo the master taught you to see through at a glance.

Many people will confuse loose-tailed sunflower and Phoenix-tailed bamboo together, coupled with the boasting of some merchants in the market, which often makes it difficult for everyone to distinguish. So here the editor teaches you the simplest way to distinguish between loose-tailed sunflower and Phoenix-tailed bamboo.

The difference between loose-tailed sunflower and Phoenix-tailed bamboo

Loose-tailed sunflower: alias yellow coconut, family belongs to palm family, loose-tailed sunflower genus. Shrubs or small trees, up to 3-8 m in origin. The stem is smooth and without burr, there are obvious leaf scars on it, showing a ring shape, and the base has many tillers, showing tufted growth. Leaves slippery and slender, pinnately compound, 40-150 cm long. Leaflets and petioles slightly curved, apex soft. Pinnae lanceolate, 20-25 cm long, asymmetrical on the left and right sides, with dorsal eminence in the middle of the leaf axis. The leaves are bright green and the petioles and stems are golden yellow.

Phyllostachys pubescens: alias Guanyin bamboo, Gramineae Bamboo subfamily Phyllostachys pubescens perennial Lignification plant. The culms are dense, short and thin, but hollow. The height of culm is 1-3m and the diameter is 0.5-1.0cm. The leaf branchlets of Phyllostachys pubescens are pendulous, with 9-13 leaves per branchlet, and the leaves are small, linear-lanceolate to lanceolate, 3. 3-6.5cm long and 0. 4-0.7cm wide. The plants are clustered, the leaves are slender and soft, curved and drooping, like a Phoenix tail.

The difference between loose-tailed sunflower and Phoenix tail bamboo is not big, the leaves are similar, it depends on the rhizome. The rhizome of Phyllostachys pubescens is similar to that of bamboo, and it grows upward, and it is not separated until it grows to a certain height. Sunflower begins to spread from the rhizome, which is easy to identify.

Culture method of loose tail sunflower

1. Soil: sunflower is not strict with soil, but it is suitable for loose and humus-rich soil. Potted sunflower can be prepared with rotten leaf soil, peat soil plus 1 to 3 river sand or perlite and base fertilizer to prepare culture soil.

2. Watering: keep the basin soil moist at ordinary times. Summer and autumn high temperature period, but also often maintain a higher air humidity around the plant, but avoid basin soil stagnant water, so as not to cause rotten roots.

3. Sunshine: light is not strict, like plenty of sunshine, but also withstand half-shade, but grow better when there is enough light. In indoor cultivation, ornamental should be placed in a place with strong scattered light; it can also withstand dark environment, but it should be moved to outdoor light regularly for better maintenance to facilitate recovery and maintain a high ornamental state.

4, temperature: loose-tailed sunflower is native to the tropics, likes high temperature environment, and has strict requirements on winter temperature. When it is lower than 10 ℃, it grows slowly and begins to enter a semi-dormant or dormant state; when it is less than 5 ℃, it can not safely survive the winter; in summer, it can be tolerated when the temperature is above 35 ℃, but its growth will be temporarily hindered. The most suitable growth temperature is 18-30 ℃.

5. Fertilization: the period from May to October is the prosperous period of its growth, so it is necessary to provide sufficient water and fertilizer conditions. Generally, rotten liquid fertilizer or compound fertilizer is applied every 1-2 weeks to promote the vigorous growth of the plant, the leaf color is thick green, fertilize less or not in autumn and winter, and keep the basin soil dry and wet at the same time.

6. Pruning: when the plant enters the dormant or semi-dormant period in winter, the branches such as thin, disease and insect, withered and overdense should be cut off.

7, insect pests: leaf spot disease, leaf tip and leaf edge are the most vulnerable, resulting in dry curl, the initial stage of the disease with 50% carbendan wettable powder 500 times liquid spray control. In addition, it may be harmful to scale insects and can be sprayed with 1500 times of omethoate EC.

The difference between loose-tailed sunflower and Phoenix-tailed bamboo and the breeding methods of loose-tailed sunflower are introduced here. I believe that when you go to the market to buy these two kinds of plants in the future, they should no longer be confused. I hope it will be helpful to you. Please stay tuned.
