peony

First, prevention and control of rotten roots: potted flowers and trees due to poor structure of potted nutritious soil, return alkali, waterlogging, resulting in rotten roots and yellow leaves. When turning the basin and changing the soil, you can cut off the rotten roots and apply sulfur powder on the wound to promote new roots.

Cutting preservative camellia, rhododendron, gardenia, begonia, magnolia, sweet-scented osmanthus and other cuttings can be dipped in sulfur powder after cutting, which can effectively prevent cuttings from rotting.

Second, to control the occurrence of diseases: flowers and trees such as powdery mildew, anthrax, black spot, gray mold, etc., spray sulfur powder when the leaves are wet in the early morning, and spray sulfur powder suspension or stone-sulfur mixture in dry weather. Sulfur powder has a special effect on the prevention and control of powdery mildew and rust.

Flowers that adjust acidity and alkalinity like acidic soil apply a certain amount of sulfur powder to the garden soil or flowerpot nutritious soil which is waterlogged, hardened and alkali-returning, which can adjust the soil PH value, reduce the harm of salt and alkali, and prevent rotting roots and nutritional deficiency.

To improve the survival rate of grafting after grafting of succulent plants, spraying sulfur powder on the interface can prevent the interface from being infected with bacteria and rot.

The function of cactus the culture method of cactus

Cactus is a plant of the genus cactus. Alias cactus, Guanyin cactus, overlord, fire cactus, etc., are cactus plants. Cactus is a tufted succulent shrub, the upper branch is broadly Obovate, Obovate-elliptic or suborbicular; flowers radiate, receptacle Obovate; seeds mostly oblate, margin slightly irregular, glabrous, yellowish brown. Cactus like strong light, resistant to heat, drought, barren, tenacious vitality, the suitable temperature for growth is 20-30 ℃. Mainly distributed in the southern and southeastern coastal areas of the United States, the West Indies, Bermuda and northern South America, southern China and Southeast Asia and other tropical and subtropical regions.

There are many kinds of cactus, there are more than 2000 species in 70-110 genera in the world, which can be divided into: fan cactus, segment cactus, crab claw cactus (crab orchid), leaf forest cactus, spherical cactus. Often grow in desert and other dry environment, known as "desert hero flower", is a kind of succulent plants. Next, let's take a look at the classification, function and breeding methods of cactus.

Classification of cactus

There are many kinds of cactus, which can be divided into: fan cactus, segmental cactus, crab claw cactus (crab orchid), leaf forest cactus, spherical cactus, climbing cactus, edible cactus and so on.

Fan cactus

They are mainly distributed in Canada, the West Indies and southern Argentina, and are the second largest family of cacti. Their appearance varies greatly, with some clumping together like bushes, while others can grow to a height of about four meters. The thorns of this genus are very large, and the colors vary from variety to breed. The more common thorns are the golden thorns of the golden black hat cactus and the white black hat cactus with white thorns.

Segmental cactus

Most of the segmental cactus grow in the forest, because there is more water in the growth environment, so they do not have a hypertrophic stem to store water, instead of a segmental stem structure, and each stem node is relatively short.

Crab claw cactus (crab orchid)

The succulent stem of crab claw cactus is segmented, which is one of its characteristics, which is also a characteristic of epiphytic cactus. Its flower shape is longer, and its sepals are colored, just like petals; during flowering, flowers grow at the end of the succulent stem, so the more branched the plant, the more flowers will bloom. Crab claw cactus flowers spread by insects, will bear fruit, but its fruit will take a year to fully mature, ripe fruit contains many black seeds, taste sweet, edible.

Leaf type forest cactus

Leaf-type forest cacti, like segmental cacti, belong to cacti that need more water. In their native land, they are attached to trees in the forest. In fact, although the thorns of some leaf-type forest cacti have been degraded, but it still has a thorn seat structure. As the name implies, the stem of this kind of cactus is shaped like long leaves, with long segments or even no segments.

Spherical cacti

The shape of spherical cactus is spherical, but under long-term cultivation, some varieties will be deformed and tend to be oval; in addition, most of them do not have verrucous protuberances, even if they are very inconspicuous.

Climbing cactus

At the same time, it is also valuable in medicine, ornamental, fruit, beauty, environmental protection and so on.

The flower language of cactus

The flower language of cactus is-- strong.

The cactus has a soft heart on the outside. At the beginning of creation, the cactus was the weakest thing in the world. It was as delicate as water and could lose her life at the slightest touch. God couldn't bear to put a suit of armor on her heart, hard as iron, with hurtful steel thorns on it. From then on, no one could see the heart of the cactus any more, and all creatures close to her would be dripping with blood. A long time later, a brave man wanted to eradicate the evil creature. The sword fell, and the cactus turned into two halves, but it was a green liquid. Originally, it is the heart of the sealed cactus, because no one understands the loneliness, turned into teardrops, green tears make the weak cactus more highlight her strength. So the flower language of cactus is-- strong.

The effect of cactus on home environment

Cactus plants have strong resistance to drought and high temperature, and there are few diseases and insect pests, so they do not need to apply fertilizer frequently. In recent years, it has been found that it has the function of reducing air pollution and purifying air: the stomata on its fleshy stem are closed during the day and opened at night, absorbing carbon dioxide, producing oxygen and increasing the concentration of negative ions in indoor air.

Culture method of cactus

(1) watering and spraying

Terrestrial cactus has obvious growth period and dormant period, the growing period should be watered, the dormant period should be watered less or even no watering. For epiphytic type, if the winter temperature is kept above 12 ℃, it can be watered and sprayed all the year round; if the winter temperature is kept below 12 ℃, watering can be reduced and stopped. Water temperature should be close to soil temperature as far as possible, early (before sunrise) and late (after sunset) in summer, from 10:00 to 11:00 in winter, and directly onto basin soil, otherwise the appearance of thorns will be affected. In addition, it is necessary to sprinkle water on the ground in summer to increase air humidity.

(2) fertilization

Fertilization should grasp the following principles: timely, appropriate amount, depending on the object. Fertilization is carried out in spring and autumn, and once every 20 days, it should be carried out in the early morning or evening on a sunny day. If the basin soil is dry, sprinkle some water on the basin soil and then apply fertilizer with a concentration of 0.05%-0.2%. The effect is better if it is watered once the next morning. Terrestrial fertilization requires fertilizers rich in potassium and phosphorus and less nitrogen, while epiphytic fertilizers require more nitrogen fertilizer.

(3) Lighting

Terrestrial type prefers plenty of sunshine, especially in winter. Generally, tall, cylindrical and flat cacti are more resistant to strong light and can be placed outdoors without sunshade in summer, while smaller spherical ones prefer semi-overcast conditions in summer, covering the top growing point of Jinzhu with a circular plastic film in June and August in summer high temperature season, so that all parts of the sphere grow evenly. Epiphytic cacti require semi-overcast conditions all the year round.

(4) temperature

The suitable temperature for cactus growth is between 20 and 35 ℃. The terrestrial type does not require a high temperature during the dormancy period in winter, but the temperature can be maintained at 4: 7 ℃ while keeping the basin soil dry. Epiphytic type, however, requires a higher temperature in winter to maintain a temperature of 10-13 ℃ or higher. When the cactus reaches 30: 35 ℃ in summer, the growth rate of most cacti slows down, and sometimes some kinds of stems turn yellow or burn, so the sun must be shaded and more water must be sprinkled on the ground to lower the temperature.

(5) Air

Cactus flowers are mostly native to desert open areas, with good ventilation and fresh air. Therefore, in the hot weather in midsummer, we should do a good job of ventilation and cooling in the cultivation site. The cultivation greenhouse should choose a well-ventilated environment and set up more vents such as windows and skylights to facilitate ventilation in the hot summer weather. If necessary, equipment such as exhaust fans, hair dryers or electric fans can also be installed to enhance the air circulation effect of the environment, so as to promote cactus flowers to spend the summer safely.

(6) Diseases and insect pests

Bacteria and fungi are harmful to cactus flowers, but the problem is not very serious. As long as cultivation conditions are improved, management measures are appropriate, prevention and eradication of diseases and pests are applied at the same time, it is easy to achieve good results. The more common diseases and insect pests are:

1. Rot. The pathogens are bacteria and fungi. The occurrence of this disease is often related to improper watering, poor drainage of basin soil and persistent excessive dampness. After discovering the diseased plant, immediately cut off the diseased tissue with a sharp knife, and apply charcoal powder or sulfur powder in the incision, at the same time control watering or changing pots, cutting or grafting separately. It is best to spray 40% copper oxychloride suspension 800-1000 times regularly on planting sites and plants as a precaution, but mainly to improve ventilation and avoid persistent excessive moisture.

two。 Insects and other animals. There are mainly shell insects, red spiders and slugs. To control scale insects, 50% omethoate emulsion can be sprayed 1000 times, red spiders can be sprayed with 20% dicofol wettable powder or 40% dicofol EC 1000 times, rodent and tide insects can be sprayed with 2000 times liquid, flower racks and around flowerpots can be sprayed with 2000 times liquid for snails and slugs, lime powder can be sprayed around flower pots, and 8% diclofenac granules can also be applied. To control cockroaches and ants, you can put drugs or sugar water to kill cockroaches and ants and kill trichlorfon.

A local girl named Sronini has been very fond of this kind of wild flowers with slightly curved stems and low-grade flowers since she was a child. When she got married, she asked for more inserts in the hall to add to the wedding atmosphere. Relatives and friends from all sides sang and danced and toasted each other frequently. Unexpectedly, the bridegroom, who was very shallow, was intoxicated after only three rounds of drunkenness. He bowed his head and leaned to the east and west, so the bride had to help him into the bedroom to rest. When people saw how similar the posture was to the growth of the wild flowers, many girls said in unison, "Oh, the flowers are really like Fulang!" From then on, the name of Fulanhua spread like wildfire.

The effect of African Chrysanthemum on Home Environment

1. It can adjust the indoor temperature. If the temperature is high, it can be lowered, and if the temperature is low, it can be increased. In hot summer, African chrysanthemum breathes, sucking hot carbon dioxide in the air into the body, and then releasing oxygen. In the process, it absorbs some of the heat, which lowers the temperature of the whole room as a whole. In winter, it is very cold both indoors and outdoors. African jasmine will breathe and generate heat in the process of breathing, driving up the temperature of the whole house and keeping warm.

2. Its role in beautifying the home can not be ignored.

3. African chrysanthemum can judge a fake light and ventilation. Human growth environment and plant growth need to be the same to a certain extent. Gerbera is a light-loving plant, cultivation chooses a place with sufficient light. The seedlings should not be planted too deep, and the root buds should be exposed to the soil. If the light is not enough, the pedicel is soft and drooping, and the quality of the cut flower is not high. The color of African chrysanthemum is dark in midsummer, especially in the case of drought and water shortage, while the flowers blooming in September-October or March-June of the following year are bright. This shows that African chrysanthemum is sensitive to temperature and light intensity, and it is necessary to keep the soil moist and free from drought in summer, cover the shading net with 50% light transmittance, and spray to the leaves to increase air humidity and lower temperature; in winter, the temperature should be not less than 10 ℃ at night and no less than 15 ℃ during the day, which are very beneficial to improve the freshness of African chrysanthemum. In addition, mites are the enemy of African chrysanthemum cultivation, once injured, not only lose the bright color, but also the shape of the petals will be incomplete.

Culture method of African chrysanthemum

The disease of African chrysanthemum is a little different from ordinary flowers, let's learn about it together!

First, when conserving African chrysanthemum, we should pay attention to the diseases that may occur on it.

1. Epidemic disease: the key technology for prevention and control is that the continuous cropping soil must be disinfected with Weibo mu and formaldehyde, the usage and dosage can be described in the instructions; shallow planting, the root neck exposed on the surface 1cm; to prevent the soil from getting too wet, the soil below 10cm can be watered. At the initial stage of the disease, some leaves became red and began to wilt, and the roots were irrigated with 58% ethyl phosphorus, aluminum, manganese and zinc 400 times, and then irrigated with 64% poisonous alum powder 500 times in the next 7 days. the application time was carried out when the temperature was low in the morning and evening, and stopped when the temperature was higher than 28 degrees Celsius. Once every 7 days, three times in a row.

2. Powdery mildew: the key technology for prevention and control is to keep the ventilation in the shed low and humid; to remove the diseased leaves in time; to spray 1500 times of methyl topiramate at the time of onset, or to control it with 20% carbendazim smoke, once every 7 days, even for 2-3 times. In addition, sulfur fumigation was used to control the disease. 20-30g sulphur powder was put into each fumigator each time. After the curtain was released at 17:00 every day, the shed was kept airtight, heated by electricity for 2 hours, and the sulfur powder was changed every 6 days for 15 consecutive days. During the onset period of powdery mildew, powdery mildew can be eliminated by fumigation for 8-10 hours every day for about 10 days.

3. Spot disease: the key technology for prevention and control is to remove the diseased leaves in time and destroy them; at the initial stage of the disease, spray 2.5% nitrilazole EC 300 times or 70% methyl thiophanate wettable powder 800 times, spray once every 7 days, and spray 2-3 times continuously.

4. Botrytis cinerea: the key technology of control is to control humidity is the key to control Botrytis cinerea. Remove the densely planted and overgrown leaves; increase ventilation and keep the air humidity at 75 per cent; water from below the canopy; in order to prevent water vapor from condensing on the flowers, open the side shed gradually after 10:00 in the morning to avoid a sharp rise in temperature in the shed; foliar spray of 1500 times of methyl topiramate was used in the early stage of the disease, and combined with aerosol for prevention and treatment.

5. Whitefly: the key technology of control is to thoroughly remove weeds; insert the yellow board for monitoring at any time, once pests are found, timely measures should be taken; good pesticide selection and correct use: whitefly is easy to produce resistance to pesticides and must be rotated. The effective pesticides are cypermethrin, avermectin, imidacloprid and so on. The spraying time was chosen at dawn, sealed the greenhouse for 4-5 hours after spraying, and sprayed continuously the next morning.

Second, temperature requirements. The cultivation facilities should be used to meet the temperature requirements of African chrysanthemum at seedling stage, growth stage and flowering stage, so as to facilitate normal growth and flowering. Outside South China, there is no open field for overwintering, so it needs to be cultivated in greenhouse, and can be cultivated in greenhouse outside the Yangtze River basin. In summer, the roof should be covered with a shade net and the plastic film on both sides of the greenhouse should be opened to cool down. When the external night temperature is close to 0C in winter, the plastic film must be covered in the shed. In case of sunny and warm weather, the southern end of the greenhouse was opened for about an hour of film ventilation at noon.

Third, lighting requirements. African chrysanthemum is a light-loving flower, which needs full light in winter, but it should pay attention to proper shading and strengthen ventilation in summer to reduce the temperature and prevent high temperature from causing dormancy.

Fourth, irrigation requirements. After planting, the seedlings should be properly moist and squatted, so as to promote the development of root system and form seedlings quickly. During the period of exuberant growth, adequate water supply should be maintained, irrigated every 3-4 days in summer and about half a month in winter. Flowering irrigation should be careful not to make the center of the leaves stained with water to prevent the flower buds from rotting. In open field cultivation, attention should be paid to waterlogging prevention. In addition, irrigation can be combined with fertilization.

Fifth, the requirement of topdressing. African chrysanthemum is a perennial flower that likes fertilizer, which has a great demand for fertilizer. the proportion of nitrogen, phosphorus and potassium is 15:18:25. Special attention should be paid to the supplement of potash when topdressing. Generally, each mu sells 2.5 kilograms of potassium acid, 1.2 kilograms of ammonium nitrate or ammonium phosphate, every 5-6 days in spring and autumn, and every 10 days in winter and summer. If the plant is semi-dormant caused by high temperature or low temperature, fertilization will be stopped.
