How to raise taro, culture methods and matters needing attention / avoid stagnant water / avoid bright light

Taro is a highly ornamental plant, its leaf color is rich, very changeable, so it is loved by many people, many people want to raise one at home, so how to raise taro? What are the breeding methods and matters needing attention of taro? Next, the editor will take you to learn about it.

First, how to raise taro and understand its habits

If we want to know how to raise taro, we must first understand the growth habits of this plant. It likes a warm and humid environment, but it is not cold-resistant, so we must pay attention to cold prevention when breeding in winter. In addition, there are many places that need to be paid attention to. Details are introduced below, and we will move on.

II. Culture methods and matters needing attention of taro

1. The choice of soil should be high in looseness.

When we cultivate taro, we should first choose soil, which is the first step and also a step to lay a good foundation. generally speaking, it is best to choose relatively loose rotten leaf soil or peat soil, which has good drainage and air permeability. to make it grow better. It is best not to choose too dry or moist soil, which is not conducive to its growth, and can easily lead to root rot if the humidity is too high.

two。 Fertilization requirements, mainly nitrogen fertilizer

In the cultivation methods and matters needing attention of taro, fertilization is a very important step, especially after entering the growing period, its demand for fertilizer is very high, basically once a week. In the choice of fertilizer, we generally use nitrogen, phosphorus and potassium fertilizer to match, but mainly with nitrogen fertilizer. And we should pay attention to dilution before fertilizing, otherwise it is easy to burn the plant.

3. Watering requirements, control watering / avoid stagnant water

Spring and summer are the peak season for the growth of taro, so we should keep the soil moist and watered frequently, so that it can grow better, but we have to control the amount of watering when watering. After the soil has a certain amount of moisture, we can stop watering, and remember that it can not be watered too much, otherwise it is easy to cause stagnant water to cause rotting roots.

4. Lighting requirements, avoid strong light

The flower-leaf taro is that this kind of plant prefers the semi-shady environment, so it is best not to put it in the strong light when breeding, otherwise it is easy to burn the plant, we can put it in the sunlight scattering place, so that it will not affect its receiving light and will not hurt the plant because the light is too strong.

5. Temperature management, 20-30 ℃

Among the methods and matters needing attention in the cultivation of taro, the environmental temperature is also a point that needs to be paid attention to. The environment suitable for its growth is between 20 and 30 ℃, so we can control the temperature properly when breeding. This kind of plant is less hardy, and the ambient temperature of its growth had better not be lower than 10 ℃, otherwise it will easily lead to yellowing of its leaves.

6. Trim regularly and disinfect the utensils first

In the process of the growth of taro, sometimes there will be the phenomenon of overgrowth, at this time we need to prune it, so that it can not only maintain its plant type, but also play a role in promoting branching, so it looks like it will burst. However, before pruning, we have to disinfect the pruning tools so as not to infect the plants with bacteria.

7. Pest control, timely prevention and control

In the process of breeding taro, if the cultivation is improper, it is easy to have bad problems such as diseases and insect pests, which do great harm to plants, so we must deal with them in time. Specific treatment methods you can refer to the flower and leaf taro pest control article, here the editor will not introduce too much.

What are the taboos about growing flowers in summer? Key points and matters needing attention in growing flowers in summer

The hot summer is coming soon, the summer climate is hot, and the rainfall is increasing, which is the exuberant period of the growth and development of most flowers and trees, and it is also a good time for cutting flowers and trees, but this season is also a time for the occurrence of a large number of diseases and insect pests, so, flowers should be maintained more carefully.

1. Sunscreen

Sunscreen can not only reduce the sun but also cool down. According to the different habits of flowers, put them in the corresponding place.

① foliage plants such as tortoise back bamboo, Brazilian wood, rubber tree, rich tree, green pineapple, etc., should be placed in a semi-shady and ventilated place; flowers, bulbous plant rhododendron, camellia, calla lily, Zhu Dinghong, gentleman orchid, etc., should be placed in a cool and ventilated place.

② succulent succulent plants such as cactus, crab claw orchid, arrow lotus, longevity flower, wax plum, pomegranate, mulberry, rose, etc., should be placed in a sunny and well-ventilated place.

③ sits in the room facing east and west, and the flowers can be placed on the east balcony or windowsill for maintenance to avoid strong light and high temperature in the afternoon. Sitting north to the south of the room, flowers can be placed on the north balcony or windowsill maintenance, reduce light intensity.

Can also be in the balcony or courtyard to build a sunshade, roof with plastic film to do sunshade net, sunshade effect is good. When planting flowers in the courtyard, you must put up the bottom of the basin to facilitate drainage and ventilation.

two。 Cooling and humidification

High temperature is bad for the growth of flowers. In general, when the temperature is 35-40 ℃, the flowers will stop growing; when the air temperature reaches more than 45 ℃, the flowers will be in danger. When the summer temperature is high and the air is dry, when the water absorption capacity of the flower root is greatly weakened, it can cool and humidify it.

① often sprays water mist on the leaves and stems of potted flowers and sprinkles water on the ground around potted flowers. According to the measurement, the ground temperature can be reduced by 1-5 ℃ immediately after spraying water, and the leaf temperature can be reduced by 1-2 ℃ after spraying water for a few minutes.

② built a sand trough in the corner of the balcony. Surround a piece of land with bricks, cover it with 3-5cm thick coarse sand, put the flowers on it, and sprinkle water on the sand surface 2-3 times a day to create a relatively cool and humid microclimate.

③ put a plank on the pool with cold water, put the flowers on the plank, and add enough cold water to the pool every day to help moisturize and cool down.

④ flowers placed indoors can also be cooled and humidified by a humidifier.

3. Dormant flowers spend the summer safely

Flowers that like warm and cool grow into dormant or semi-dormant state during the summer high temperature period, such as cyclamen, hanging golden bell, calla lotus, flower and leaf taro, lotus, begonia, etc., various measures should be taken to make it safe to spend the summer.

① controls the temperature. Avoid bright light and put dormant flowers in a cool and ventilated place after summer. When the temperature is high, it is often necessary to spray water on the plants and the ground to cool down.

② controls water quantity. The amount of water should be kept slightly moist in the basin soil. Watering too much pot soil for a long time is easy to cause rotten roots, watering too little is easy to make the roots shrink.

③ stopped fertilizing. The growth of dormant flowers consumes very little nutrients, and fertilization is easy to cause rotting roots and even death.

Cyclamen, hyacinth, tulips and other bulb flowers can be dug up and stored in a cool, ventilated, dry and sheltered place after the stems and leaves have withered on the ground.

4. Pruning and shaping

If flowers grow too much in summer, they should wipe buds in time, cut short and cut too long branches, and cut too dense branches.

The taboos for flower conservation in summer are as follows:

(1) avoid high temperature, high humidity and poor ventilation

Poor indoor ventilation, coupled with high temperature, high humidity, prone to diseases and insect pests, affect beauty and growth, and even lead to death. Indoor ventilation should be strengthened, and 1000 times of methyl topiramate or 1000 times of sterilized liquid can be sprayed regularly for prevention and control.

(2) the taboo light is too weak if the curtains are closed during the day in summer, resulting in dim light, which will affect the growth of flowers and is not conducive to viewing. Therefore, the room where plants are placed should be properly illuminated and should not be too dark.

(3) avoid using air conditioners.

When the air conditioning is used in the cooling room, the air humidity is small, which is easy to wilt the leaves of foliage plants and affect the luster of the leaves, and the edges of the leaves will become scorched when it is serious. The leaves of the flowers that are directly blown out of the air-conditioned outlet will soon lose water and dry up. The plants should be placed away from the air-conditioned outlet and pay attention to spraying more water to improve the indoor air humidity.

(4) avoid improper use of water

The temperature in summer is too high, water evaporation is fast, watering should be timely. Potted flowers placed outdoors should be cleaned up in time after it rains.

The above are the main points and taboos of growing flowers in summer, so florists should pay attention to these mistakes in summer.

How to raise family potted flowers and plants in summer? What should we pay attention to?

The light is suitable to prevent exposure.

Light is the energy source for flowers to produce nutrients, so many flowers can blossom and flourish only under sufficient light conditions. However, different flowers or different growth stages of the same flower have different requirements for light, so there are flower proverbs such as "Yin camellia, yang peony, half yin and half yang four seasons orchid".

Generally like the flowers with plenty of light, such as rose, pomegranate, sweet-scented osmanthus, Riley, plum blossom, peony, poinsettia, variegated wood, chrysanthemum, Dahlia, Milan, Prynne, Fusang, crape myrtle, kumquat, aquatic flowers, cactus, etc., after leaving the room in spring, they should be kept in a sunny place, but in the middle of summer, they should also be moved to a slightly shaded place to prevent strong light exposure.

Generally negative or strongly negative flowers, such as orchids, tortoise back bamboos, hanging orchids, asparagus, camellias, rhododendrons, ivy, masts, evergreens, begonias, brown bamboos, Phyllostachys pubescens, orchids, ferns and magnolia, etc., should be maintained in an environment with good ventilation and 50-80% shade in summer. if exposed to direct light, it will cause branches and leaves to turn yellow and even die. For this kind of flowers, it is best to put them on the balcony or windowsill facing east or north in summer, or to cultivate them in a well-ventilated place with bright scattered light; you can also use reeds or bamboo curtains to set up a shade shed and put the flowerpot under the shade shed for maintenance. in this way, the light intensity can be reduced to facilitate the robust growth of flowers.

Cooling and humidification pay attention to ventilation

Temperature is a necessary condition for the growth of flowers. Due to the long-term influence of the natural climatic conditions of the place of origin, different flowers have formed the unique optimum, highest and lowest temperature. For most flowers, the suitable temperature for growth is 20-30 ℃. The highest temperature in summer in most areas of China can reach more than 30C. When the temperature exceeds the maximum limit of flower growth, the normal life activity of flowers will be blocked, resulting in short plants, partial burns of leaves, reduction of flower quantity and shortening of florescence. Many kinds of flowers bloom little or not in summer, and the influence of high temperature on their normal growth is an important reason.

Tropical and subtropical flowers, such as Michelia, camellias, rhododendrons, orchids, etc., grow under warm and humid marine climate for a long time, and form special ecological requirements that like air and moisture in the course of their childbearing. It is generally required that the air humidity should not be less than 80%. If it can meet the requirements of air humidity in maintenance, it will give birth well; otherwise, it will be prone to poor growth, leaf margin drying, tender leaves scorching and so on.

Under family conditions, there are four main ways to cool and humidify in summer:

The main results are as follows: (1) during the normal watering in summer, according to the different requirements of air humidity of different flowers, spray water on the branches and leaves 2 or 3 times a day, and spray water on the ground of flowerpots 1 or 2 times at the same time.

(2) spread sand to cool the north or east balcony with a thick layer of coarse sand, then put the flowerpot on the sand surface, sprinkle water on the sand surface 1-2 times a day in the second season, and use the water contained in the sand to absorb heat in the air. the purpose of cooling and humidification can be achieved.

(3) A prefabricated board of hardwood or cement is used to cool the pool, put on the tank containing cold water, and then put the flowerpot on the board or cement board, add water once a day, and the water evaporates continuously after being heated, which can not only increase the air humidity, but also lower the temperature.

(4) put the flowerpot in the well-ventilated place with scattered light, spray clean water 1-2 times a day, and use electric fan to cool down.

Rational watering and proper fertilization

Summer temperature is high, evaporation is fast, plant transpiration is also strong, flowers need more water, so for most flowers, there should be sufficient water supply. As for how to control the amount of water in summer? It should be determined according to the type of flowers, the plant size and the actual dry and wet condition of the basin soil. General grass flowers themselves have more water content, transpiration intensity, watering should be more; general woody flowers can be watered less appropriately. Under normal circumstances, general flowers should be watered 1-2 times a day, never half waist water, otherwise the leaves will often curl and yellowing, for a long time, the whole plant will die.

It is best to use Rain Water to water flowers in summer, or dry tap water for 1 to 2 days first. Watering time is appropriate in the morning and evening, do not pour cold water at noon, because the temperature is very high at this time, the temperature outside can often reach about 40 ℃, not only transpiration is strong, but also water evaporation is fast, suddenly the cold water is excited, the foliar cells turn from tense to wilting, so that the leaves scorch, and when serious, it will cause the whole plant to die. This phenomenon is particularly obvious in some grass flowers. If in the early stage of flower bud gestation, flowering and fruit setting, cold water is watered at noon in summer, it is also easy to cause bud drop, flower drop and fruit drop phenomenon.

What needs to be specially mentioned here is: due to the high soil temperature in hot summer, it must be watered in time after the shower to eliminate the high humidity and muggy heat in the basin soil and reduce the basin soil temperature; the stagnant water in the basin after the rainstorm should be poured out immediately, or the basin soil should be pierced with bamboo sticks (do not hurt the root) to let the water flow out from the drainage hole at the bottom of the basin to avoid rotting the root.

When applying fertilizer to potted flowers in summer, we should grasp the principle of "applying thin fertilizer frequently". Excessive concentration of fertilizer is easy to cause rotten roots, generally exuberant flowers, about every 10-15 days to apply dilute liquid fertilizer. Fertilization should be carried out on sunny days and when the basin soil is dry. Because the root is easy to rot when fertilized in wet soil. The fertilization time should be in the evening after getting cooler. Water should be watered once the day after fertilization. The type of fertilization varies from flower to flower. Flowers that like acidic soil, such as camellias, rhododendrons, magnolia, maizi, Riley, etc., should not apply alkaline fertilizers, but should choose acidic or physiologically acidic fertilizers, such as calcium superphosphate, ammonium sulfate, ammonium nitrate and ferrous sulfate. When flowers enter the flower bud differentiation and bud stage, it is appropriate to apply more phosphorus and potassium fertilizer to promote more flowering. Flowers dominated by foliage should be fertilized with nitrogen fertilizer in order to promote the green color of leaves. Bulbous flowers, should apply more potash fertilizer, in order to enrich the bulb. For dahlias with large flowers and a long flowering period, it is necessary to apply an appropriate amount of complete fertilizer in the bud flowering stage in order to make all flowers blooming and beautiful. For the flowers that mainly watch the fruit, the fertilizer and water should be properly controlled during flowering, and sufficient complete fertilizer should be applied in the strong fruit stage, the fruit will be large and more.

In the process of pot flower maintenance, if the plant is short and thin, the branch is small and the leaf color is yellowish, which is the manifestation of lack of nitrogen fertilizer, nitrogen fertilizer should be added in time; if the plant grows slowly, the leaf curls, the plant is short, and the root system is underdeveloped, it is mostly caused by phosphorus deficiency. Fertilizer based on phosphate fertilizer should be supplemented. If the leaf tip of the leaf edge turns yellow (first the old leaf then the new leaf) and then turns brown and falls off, the stem is soft and easy to bend, which is mostly caused by lack of potassium, potash fertilizer should be applied.

Dormant flowers spend the summer safely

Some flowers, such as cyclamen, hanging golden bell, begonia, daffodil, geranium, taro, magnolia, freesia, paulownia, tulips, lotus flowers, etc., enter a semi-dormant or dormant state in the summer high temperature season, showing a decline or pause in growth rate in order to resist the harm of external adverse environmental conditions. In order to make this kind of flowers safely through the summer dormancy period, it is necessary to take corresponding measures to take meticulous nursing according to the physiological characteristics of their dormancy period. The main measures are:

(1) move dormant flowers to a shady and ventilated place after summer to avoid direct sunlight and rain, otherwise it will easily cause rotting roots or even death.

(2) watering should be strictly controlled. During dormancy, too much watering, basin soil for a long time wet, very easy to rot roots, watering too little, basin soil is too dry, and easy to make the root system atrophy. Therefore, watering is appropriate to keep the basin soil slightly moist. But often spray water on the branches and leaves and sprinkle water on the ground around the flowerpot to form a moist and cool microclimate, which is conducive to dormancy. However, for flowers such as paulownia with dense fluff on the leaf surface and cyclamen whose flower buds are sensitive to moisture, it is not suitable to spray water on the leaf surface or leaf center.

(3) stop applying any fertilizer. Because the physiological activity of flowers is very weak during dormancy, there is no need for fertilizer. If fertilized, it is also easy to cause rotten roots, rotten balls, and even the death of the whole plant.

Pruning and shaping to prevent overgrowth

After many flowers enter the summer, they are often easy to grow in vain, affecting their flowering and fruiting. In order to keep the plant shape beautiful and fruity, it needs to be trimmed and reshaped. Summer pruning is generally based on measures such as coring, wiping buds, removing leaves, thinning buds, thinning fruits and so on.

(1) pick some grass flowers, such as Begonia, Golden Bell, a string of red, chrysanthemum, Dutch chrysanthemum, early chrysanthemum, etc., and pinch off their tops when they reach a certain height to promote them to be more branched and bloom. Some woody flowers, such as kumquat, should also be heart-picked when the branches grow to about 15-20 cm in order to bear more fruit.

(2) in summer, many flowers often sprout adventitious buds from the base of the stem or branches, which should be erased in time so as not to consume nutrients and disturb the plant shape.

(3) to remove leaves, some foliage flowers should properly cut off old leaves and promote new leaves, then the leaf color will be more beautiful.

(4) Bud thinning, fruit thinning for flowers that are mainly ornamental, such as dahlias, chrysanthemums, roses, etc., excessive buds should be removed in time; for ornamental flowers, such as kumquat, pomegranate, bergamot, etc., when the young fruit grows to the size of soybean grains, the excess young fruit should be removed; for some flowers that cannot bear seeds or are not ready to collect seeds, cut off the residual flowers in time.

(5) plastic surgery for poinsettia, plum blossom, green peach, tiger thorn plum and other flowers, often bend each side branch in summer to make the plant shape plump and graceful.

Comprehensive management of disease prevention and pest control

High temperature and humidity in summer are conducive to the occurrence of a large number of diseases and insect pests. We should carry out the policy of "prevention first and comprehensive prevention and control" and do a good job in prevention and control in the spirit of "early treatment, small treatment and cure" to ensure the healthy growth of flowers.

The main results are as follows: (1) the common diseases in summer are powdery mildew, anthracnose, gray mold, leaf spot, nematode, bacterial soft rot and so on. Powdery mildew is mainly harmful to rose, plum blossom, peony, chrysanthemum, dahlia, begonia, melon leaf chrysanthemum, inverted golden bell and so on. After the damage, the plants were short, the tender shoots were curved, and the leaves were uneven or curled. Buds, leaves, shoots and buds, as if covered with a layer of white powder and grow many small black spots, serious leaves withered and withered, or even the whole plant died. Anthrax is mainly harmful to orchids, Magnolia, Milan, plum blossoms, rubber trees, cactus and so on. After most flowers are infected by bacteria, there are nearly round disease spots on the leaf surface, the edges are mostly purplish brown or dark brown, the center is light brown or grayish white, and the disease spots are often arranged with small black spots in the shape of wheels. The leaves withered and died when the disease was serious. Botrytis cinerea is mainly harmful to peony, peony, cyclamen, begonia, inverted Admiralty and so on. The damaged parts such as leaves, stems and flowers are brown or purplish brown rotten, gray mildew grows on the disease spot when the weather is wet, and the whole plant dies in severe cases. To prevent and cure the above three diseases, the following methods can be adopted: ① thoroughly remove dead branches and leaves in early spring, and timely cut off diseased schools, leaves, buds and so on, so as to reduce the source of bacteria; ② strengthens cultivation management, reasonable fertilization and watering, pays attention to ventilation and light, makes plant growth strong, and improves disease resistance; spraying 50% carbendazim or 50% thiophanate 500,800 times in the initial stage of ②.

(2)The common pests in summer are piercing-sucking mouthparts and chewing mouthparts. The former mainly aphids, red spiders, whiteflies, scale insects and so on. This kind of pest often gathers in leaves, tender stems, buds, branches and other parts, piercing flowers with needle-like mouthparts to suck juice, causing leaves to turn yellow and curl, causing leaves to wither and fall off. Control method, available 50% dichlorvos emulsion 1000-1500 times liquid spray. This medicine is easy to make plum blossom, cherry blossom, azalea, plum blossom and other flowers and trees produce phytotoxicity, so these flowers and trees should be banned. The latter mainly includes moths, butterfly larvae, various beetles and underground pests. These insects nibble at leaves and bite roots, causing plants to wither and die. The control method is spraying 1000-1500 times solution of 50% dichlorvos emulsion or irrigating rhizosphere with 500-800 times solution. Summer temperature is high, pesticides are easy to volatilize, coupled with high temperature when the human body's emission function enhanced, skin absorption increased, so the poison is easy to enter the human body and poisoning, so summer application, it is appropriate to move the flowerpot outdoors, in the morning and evening.
