Matters needing attention in Fulutong Culture

The moisture varies with different seasons.

High summer temperature, in addition to adequate watering, but also need to spray water to the leaves once a day.

In late autumn and early winter, when the temperature drops below 15 ℃, watering should be controlled.

In winter, the amount of boiling water should be reduced, or water spraying should be used instead of watering, and the basin soil should be kept slightly moist and slightly dry, but when spraying foliage, we should pay attention to make the water temperature basically consistent with room temperature.

Loosen the soil in time

The growing season can be combined with fertilization to loosen the soil once a month to keep the basin soil permeable for a long time and avoid rotting roots caused by the consolidation of the basin soil.

Put the potted plants in a ventilated place.

Family potted plants can be placed in a well-ventilated place near the south entrance, north or east windows in summer, and indoor light in winter.

adequate manuring

Stop applying nitrogen fertilizer after the Mid-Autumn Festival, and apply 1-Mel phosphorus and potassium fertilizer twice to increase the cold resistance of the plant and make it survive the winter smoothly.

After the beginning of winter, the plant has stopped growing and should stop fertilizing so as not to hurt the roots.

Culture skills and points for attention of round-leaf tree how to raise round-leaf tree

The round leaf Fulu paulownia branches are soft, the plant branches are more, and the growing leaves are mostly small leaves, showing a round shape. The leaves of round leaf are oily green and have high ornamental value, so it is good to plant them in the courtyard or indoors.

How to raise Fulutong with round leaves

First, how to raise round-leaf flutong-- Fertilizer is usually applied every two weeks in a pot. Choose a special fertilizer and dilute it as a liquid fertilizer, but don't continue to apply fertilizer after September. Can let the plant branches and leaves can have enough space to grow, smoothly through the winter.

Second, how to raise round-leaf tree trees-- changing pots is suitable for planting in sunny environments in winter and properly watered. Every two years, the round leaf flutong needs to change the basin, the basin soil needs to be moist and add a certain amount of humus, the basin soil can use rotten leaf soil, add peat soil, and add some chicken manure as fertilizer.

Third, how to raise round-leaf tree tree-- watering round-leaf tree tree does not like drought, so it should be watered frequently. At the same time, the soil is moist but there is no stagnant water. It is often possible to spray some water mist around the plant to keep the leaves green and give it a moist growing environment.

Fourth, how to raise round-leaf tree tree-- it can tolerate semi-shade and is suitable for growing effectively outside or indoors illuminated by fluorescent lamps. It is more sensitive to environmental changes, so before it adapts to the environment, it should be watered more to replenish nutrients.

Fulutong (scientific name: Polyscias guifoylei Bailey), also known as round leaf Nanyansen, round leaf Nanyang ginseng, belongs to the evergreen shrub of Acanthopanax senticosus. Native to the Pacific islands. The plant height is 1 to 3 meters, the lateral branches are slender, and the branch lenticels are obvious. Leaves alternate, odd-pinnate, leaflets 3-4 pairs, opposite, elliptic or long elliptic, serrated margin, leaf green often with white spots, scattered inflorescences, flowers small. Pale green is mainly for potted plants, garden trees and hedges. Contact with its juice may cause a rash; when touching the mouth, it sometimes causes swelling and pain and is unable to swallow. 1. Morphological characteristics.

Evergreen shrubs or small trees, plants much branched, stems grayish brown, densely lenticels. Branches soft, leaves alternate, odd-pinnate compound leaves, leaflets 3-4 pairs, opposite, elliptic or long elliptic, serrated margin, leaf green often with white spots, scattered inflorescences, flowers small. Pale green. Mainly for potted plants, garden trees and hedges.

2. Cultivation techniques.

Propagation method cuttage

It can be carried out in both spring and autumn, but the effect of spring planting is better. Between March and April, 10-15 cm leaves can be cut, leaving only 2-3 leaves at the end, and the lower incision should be located at 0.2cm below the node. Soak in 500ppm's indolebutyric acid or No. 1 ABT rooting solution for 10 seconds, and then insert it into the sand bed or vermiculite. A small amount of cuttings can be made with vermiculite in a wide-mouth flowerpot. After pouring through water, it can be covered with plastic film to moisturize, maintain the proper temperature for rooting at 25: 30 ℃, and take root in 40% 50% shading at 20: 30 days. Cuttings germinate new buds and then transplant them into pots.

Pressing strip

From May to June, the sturdy stem was selected and peeled 20 to 25 centimeters from the top. The peeling width was about 2 to 3 times of the stem diameter. The peat or mud bitter medicine was used to wrap the ring peeling place and knead it into a soil mass. The plastic film was used to wrap it tightly, and the water port was left at the top. If the stem is thinner and cannot support the soil mass, you can insert a bamboo pole as a support and tie the soil mass to the bamboo pole.

Maintenance and management temperature

The near temperature of its growth is 15: 30 ℃, of which it can be maintained at 20: 30 ℃ from April to October and at 13: 20 ℃ from October to April of the following year. Beautiful plants are usually more delicate, and so is Fulutong. Its variegated varieties are less resistant to cold. In general, even pure green leaf varieties should maintain a room temperature of no less than 10 ℃ in winter. When the summer temperature is more than 32 ℃, it can not be ignored, mass production should build a shed for shade, family viewing should be placed in a shady place, and water should be sprayed around to cool it, so as to create a cool small environment close to the original conditions. In late autumn and early winter, when the temperature drops to 15 ℃, it should be moved indoors in time to avoid cold damage. If the room temperature can be maintained more than 20 ℃ in winter, the stems and leaves will continue to grow; if the temperature is not high, the plant will stop growing and enter a semi-dormant state.

Light

Take round-leaf flutong as an example, it needs bright light, and insufficient light can easily cause long stems and leaves, dim leaves, and faded markings, but at the same time avoid strong light exposure, especially after a long rain in early summer, to prevent leaves from being burned. Family potted plants, usually can be placed in a well-ventilated place, summer can be placed in front of the north or east window, winter should be placed in indoor light is better. For productive cultivation, from mid-spring to the Mid-Autumn Festival, should be placed in the shade, according to the intensity of light and the length of light, shading 40% 60%. In short, it grows most vigorously in an environment with half-light and bright scattered light.

Moisture content

Potted Fulutong likes wetter soil and air environment. During the growing period, there should be sufficient water supply, and then watering the surface of the basin soil after drying, the soil should be slightly dry, but it should not be watered too much to avoid causing stagnant water and rotting roots. The temperature is high in midsummer, in addition to sufficient watering, it is necessary to spray water on the leaf surface once a day, which can not only make the leaf surface clean and bright, but also improve the air humidity around the plant. In late autumn and early winter, when the temperature drops below 15 ℃, watering should be controlled. In winter, the amount of boiling water should be reduced, or water spraying should be used instead of watering, and the basin soil should be kept slightly moist and slightly dry, but when spraying foliage, we should pay attention to make the water temperature basically consistent with room temperature.

Soil

Loose and fertile sandy loam with good drainage is the best to provide it with a loose, moist and fertile soil environment. Pot soil can be mixed with 4 parts of rotten leaf soil, 4 parts of garden soil, 2 parts of sand and a small amount of retted cake fertilizer or bone powder. The growing season can be combined with fertilization to loosen the soil once a month to keep the basin soil permeable for a long time and avoid rotting roots caused by the consolidation of the basin soil. Open field or shade under the plant, in the plum rainy season or encounter continuous rainy weather, should strengthen the inspection, found that there is stagnant water in the basin, should be promptly poured out and turned to change the soil, so as to avoid falling leaves or rotting roots. In general, the soil is changed once every two years in the spring.

Fertilizer application

Round leaf flutong and so on require sufficient fertilizer. In the period of vigorous growth from April to June, thin cake fertilizer can be irrigated once a month, or low concentration of poultry fertilizer can be used, but organic fertilizer can not be attached to the leaves. The fertilization time can be arranged after loosening the soil and pruning or before the rain, and it is best to sprinkle the foliage with water after pouring organic fertilizer. A mixture of 0.2% urea and 0.1% potassium dihydrogen phosphate can be irrigated in a family pot plant, or a small amount of multi-component slow-release compound fertilizer particles can be scattered or buried on the surface of the potted soil. Stop applying nitrogen fertilizer after the Mid-Autumn Festival and topdressing phosphorus and potassium fertilizer twice to increase the cold resistance of the plant and make it survive the winter smoothly. After the beginning of winter, the plant has stopped growing and should stop fertilizing so as not to hurt the roots.

Disease and insect control of anthracnose

The disease often occurs at the tip or edge of the leaf, and begins with a watery macula, gray-white or grayish brown in the center, with inconspicuous moire and dark brown edges; in the later stage, there are many small black spots on the spot, which are arranged in the shape of a wheel, and finally the spot dries up. The disease occurs seriously at the lower limit of insufficient light, poor ventilation and too much nitrogen fertilizer. It is necessary to strengthen light and ventilation, and pay attention to the balance of nitrogen, phosphorus and potassium when fertilizing. If a disease occurs, the diseased leaves should be removed and destroyed in time. At the initial stage of the disease, the plants were sprayed with the same amount of 80% anthrax Fumei wettable powder or 50% carbendazim wettable powder or 50% methyl topiramate wettable parts powder or 1000 times of chlorothalonil and 1000 times of methyl topiramate, the latter was the best, once every 10 days for 3 times.

Shell worm

Under the conditions of poor ventilation, poor light, high temperature and high humidity, plants are vulnerable to a variety of shell insects. During the peak incubation period of nymphs, the plants can be sprayed with 1500 times of 25% propofol wettable powder or 40% of 2000 times of fast killing or 1000 times of omethoate EC.
