Key points of maintenance and management of Huili

Huili is an evergreen tree or shrub with strong adaptability, so it is not difficult to plant. Cinnamomum chinense has luxuriant branches and large and fragrant flowers, which is very suitable for planting in the courtyard, and some flower friends will plant it in the pot, so what problems should Grey Li pay attention to in the process of cultivation?

Huili

1. Reasonable dimming. Grey likes the warm sunshine, but summer and autumn should avoid direct sunlight at noon so as not to cause leaf burns. At the same time, its phototropism is strong, and it is necessary to turn the flowerpot every 10 to 15 days indoors to prevent the crown from deviating, and it should not be placed for more than two months in the environment of insufficient light, otherwise the leaves will yellowing and fall off due to lack of light.

2. Reasonable humidification. Huili likes the environment with high humidity and good ventilation. Therefore, more water should be watered in summer and placed in the shade. At the same time, spray foliar water to increase local air humidity to keep the leaves green.

3. Rational fertilization. During the growing period, the mature thin bean cake fertilizer with moderate proportion of nitrogen, phosphorus and potassium was applied every 15 to 20 days, and attention should be paid to prevent excessive nitrogen fertilizer from causing overgrowth and affecting flowering and tree shape. After entering autumn, 0.2%-0.3% potassium dihydrogen phosphate should be properly sprayed, the amount of watering should be gradually reduced at the end of autumn, and fertilization should be stopped. In winter, the northern potted plant Huili can survive the winter by putting it in the room above 5 ℃.

4. Reasonable pruning. Huili sprouts and tillers are relatively strong, extremely resistant to pruning, and can be shaped and pruned at will during the growing period, usually cut into spherical, platform and fan shape. in order to maintain a beautiful tree shape, the tillering buds at the bottom of the plant should be cut off in time so as not to consume too much nutrients.

How does Grey raise it? How to cultivate and manage ash ash, also known as African jasmine, Chinese ash, is an evergreen tree or shrub, sometimes climbing. It is sunny, shady and cold-resistant. It is green and green all the year round and grows well in the south subtropics. Lax requirements for soil, strong adaptability, rough growth and easy cultivation. Huili is an excellent indoor foliage plant with luxuriant branches, beautiful tree shape, nearly fleshy leaves and bright green leaves. For novice flower friends may not know its cultivation and management techniques, the following editor will specifically talk about the key points of Huili maintenance for the majority of flower friends for reference and learning. 1, reasonable dimming gray lively like the warm sun environment, but summer and autumn should avoid the noon sun direct light, so as not to cause leaf burns. At the same time, its phototropism is strong, and it is necessary to turn the flowerpot every 10 to 15 days indoors to prevent the crown from deviating, and it should not be placed for more than two months in the environment of insufficient light, otherwise the leaves will yellowing and fall off due to lack of light. 2. Reasonable humidification Huili prefers the environment with high humidity and good ventilation. Therefore, more water should be watered in summer and placed in the shade. At the same time, spray foliar water to increase local air humidity to keep the leaves green. 3. During the growing period of rational fertilization, the mature thin bean cake fertilizer with moderate proportion of nitrogen, phosphorus and potassium should be applied every 15 to 20 days, and attention should be paid to prevent excessive nitrogen fertilizer from overgrowing, affecting flowering and tree shape. After entering autumn, 0.2%-0.3% potassium dihydrogen phosphate should be properly sprayed, the amount of watering should be gradually reduced at the end of autumn, and fertilization should be stopped. In winter, the northern potted plant Huili can survive the winter by putting it in the room above 5 ℃. 4. Reasonable pruning of Huili sprouting and tillering is relatively strong, extremely resistant to pruning, and can be shaped and pruned at will during the growing period, which can usually be cut into spherical, platform and fan shape. in order to maintain a beautiful tree shape, the tillering buds at the bottom of the plant should be cut off in time so as not to consume too much nutrients. 5. Huili can be propagated by cutting, sowing, striping and ramet, but cutting is the main method in the north. From July to August, the branches of the same year were cut into 8 cm and 10 cm for cuttings, and 3-4 top leaves were retained and inserted into clean river sand. They were placed in the greenhouse and rooting in 40-60 days, with a survival rate of more than 85%. 6. The soil of Huili, the cultivation medium, should be cultivated in loose, fertile and well-drained sandy soil. Potted plants in the north can be prepared with 7 parts of rotten leaf soil, 1 part of river sand, 1 part of retted organic fertilizer and 1 part of fermented sawdust. During the growing season, the potted plants were loosened once a month to keep their roots in a good state of penetration. 7. disease and pest control anthrax: anthrax mostly occurs on twigs and leaves, with nearly round to irregular sunken spots, brown edges, gray-white to grayish brown in the center, and sparse black grains on the top, which is its conidium disk. Prevention and treatment: at the initial stage of the disease, 50% carbendazim wettable powder 800 times, 25% chlorothalonil wettable powder 800 times, or 25% carbendazim wettable powder 500 times, alternately sprayed every 10 days for 3 to 4 times. Sunburn: sunburn in the heat of summer when the shade is not in place, the young shoots and young leaves of potted African jasmine are prone to sunburn, which is characterized by gray or light white burn spots on the leaves. Prevention and control methods: use shading net to shade and change position properly; in high temperature and dry season, appropriately increase watering times and amount of water, and if necessary, pour water on the leaf surface; for the burned plants, move them to the shade shed in time, cut off the burnt shoots and young leaves, strengthen water and fertilizer management, and make the plants return to health as soon as possible. The adults and nymphs of banyan thrips can be harmful to ash, mainly to young leaves and buds, but not to old leaves. Adults and nymphs file sucking juice along both sides of the main vein of the tender leaf, which can form galls on the leaf surface; seriously cause deformities, such as leaf distortion or curl along the main vein. The phenomenon of adults and nymphs clustered together can be seen on a leaf. Physical control: for plants damaged by a small number of banyan tube thrips, the occurrence of banyan tube thrips can be controlled by removing the branches and leaves damaged by insects and burning them centrally. Biological control: the use of banyan thrips natural enemies of insects, such as seven-star ladybug, tortoise ladybug and other lady beetles adults, larvae can eat banyan thrips. Chemical control: for plants that have not been damaged by banyan tube thrips, they can be prevented by spraying 2500 times of Tianwang liquid or 1000 times of Jinzun liquid when drawing new leaves; for plants that have already suffered from insect pests, they can be sprayed every 6-7 days, 3-4 times according to the situation. Conclusion: the above is the introduction of the maintenance methods of Huili. I hope you can communicate more about the planting experience of Huili. The culture method of ash ash wood

The culture method of ash ash wood

The basic information of Huashili wood

Scientific name: Fagraea sasakii alias: ash, ash wood, green yellow fruit, African jasmine, African kapok, hook orchid cinnamon.

Families and genera: Brucaceae, Cinnamomum. There are also those who separately list it as Gray Like.

Evergreen shrubs or small trees, shrubs up to 5 × 12 m. The branchlets are stout, with protruding leaf scars on the branches. Leaves opposite, slightly fleshy, oblong, elliptic to Obovate, 7-13 cm long and 3-4.5 cm wide, entire, apex acuminate or rounded and apiculate, base attenuate decurrent, glossy. May flowering, inflorescence terminal, there are 1-3 flowers, white to yellow-white, fragrant. Fruit ovate, apically convex, shiny, ca. 3 cm.

Cinnamomum chinense is the most widely used indoor foliage plant in recent years because of its luxuriant branches, bright green leaves, white or slightly yellow flowers, light fragrance and shade tolerance.

[propagation of Cinnamomum chinense] cutting, ramet, striping, sowing.

(1) Cuttage: in April, rainy season or October. Cut 12-15 cm annual or current-year branches as cuttings, leave 2-3 leaves on them and cut off half of the leaves. After insertion, under the conditions of semi-shade and high environmental humidity, it took root for 1-2 months, and the survival rate was more than 80%.

(2) ramet: before the plant germinated in spring. The tufted plants were cut into several clumps with no less than 2-3 stems, each with no less than 2-3 stems, and then planted separately.

(3) Strip pressing: from April to June, using buried soil pressing method or high-altitude pressing method. It can take root 40 ~ 50 days after pressing.

(4) sowing: it can be sown immediately after the fruit is ripe from October to December, and it can sprout in the spring of late autumn and early winter. The seeds can also be stored in sand for overwintering and whitened in spring, and the thickness of the sown soil is 2cm to 3cm.

[key points of planting and cultivation of ash ash wood]

(1) temperature: like warmth, and the most suitable temperature for growth is 18 °C and 32 °C. Not cold-resistant, the overwintering temperature should not be lower than 0 °C, preferably above 5 °C. Leaves and shoots are easy to be cold or frozen when the temperature is low. If frozen, it is difficult to restore growth in a short period of time in the second year. You can take the measure of adding double-layer plastic bags to keep warm. It does not adapt to the high temperature climate, and the plant growth is inhibited when the summer temperature is higher than 38 °C. Measures such as shading, strengthening ventilation and spraying water should be taken to reduce the temperature.

(2) Illumination: like the light, but can not bear the direct sunlight, otherwise it will burn the leaves. Shading should be carried out from May to September, or the sound should be placed in a place with sufficient scattered light. Although it can tolerate shade, the leaves lose green, yellowing and deciduous leaves when overcast. When making indoor furnishings, if the indoor lighting is not ideal, the display time should not exceed 1 month. When withdrawing, do not immediately move the plant to a place with strong light, but should be kept in a shade shed or other semi-shaded place for 1 week or 2 weeks, otherwise it will cause serious burns. If the sunburn is serious, the injured part should be shrunk, but it is difficult for the plant to restore good ornamental property in a short period of time. Plenty of sunshine should be given at other times.

(3) watering: like the moist soil environment, not resistant to drought. Because of the rapid growth, it needs a lot of water. During the growth period, we should fully supply water, keep the basin soil moist and prevent the basin soil from being too dry or too wet. If the basin soil is too dry, the newly drawn shoots will wilt. If it happens, the leaves should be treated first.

Spray some water, wait for the leaves to recover slightly before the appropriate amount of water to the basin soil; basin soil is too wet, it is very easy to cause rotten roots and make the leaves yellow and fall off, plum rainy season should prevent basin soil stagnant water. Watering should be controlled in winter to keep the basin soil in a dry state.

(4) Environmental humidity: like the warm and moist environment, the growing season is sunny and dry, we should often spray water to the branches and leaves and the surrounding environment, in order to improve the air relative humidity and facilitate the growth of plants.

(5) fertilization: plants begin to grow in spring and enter the flowering stage in May. Fertilizer combined with nitrogen, phosphorus and potassium should be applied once a month to promote branch and leaf growth and blossom. Nitrogen fertilizer was applied once every half month after flowering. Stop applying nitrogen fertilizer after autumn and topdressing phosphorus and potassium fertilizer once a month to improve the cold resistance of the plant. If 0.2% ferrous sulfate is added to the fertilizer during the growing season, leaf yellowing can be prevented. Stop fertilizing in winter.

(6) pruning: strong sprouting ability and resistance to pruning. Topping was carried out when the seedling height was 10 cm to promote the growth of lateral branches. It can be molded after 2 or 3 times topping, and the plant can be trimmed into various shapes according to the need. In the future, the branches protruding from the crown were cut short to maintain a good plant shape. For the plants damaged by sunburn, they should be moved into the semi-shade, cut off the severely burned shoots and young leaves, and strengthen the management of fertilizer and water, so that the plants can restore good ornamental quality.

(7) turn the basin: turn the basin once every 1-2 years, which should be carried out in spring and autumn. Like loose, fertile, well-drained sandy loam, the matrix can be prepared with rotten leaf soil, peat soil, fermented sawdust, river sand and other materials, and mixed with appropriate amount of organic fertilizer as base fertilizer.

(8) Disease and pest control: strong disease resistance, few diseases and insect pests. But sometimes there are anthracnose, short-frontal negative locust, shell insects and other diseases and insect pests.

[common problems in planting and rearing of ash ash wood]

Common problems are caused by gray or light white spots on young shoots and young leaves. The edge line is not obvious, usually caused by excessive light, there are nearly round to irregular sunken spots on the magnetic tender shoots and leaves, and the edges are brown. the central gray-white to grayish brown is often caused by anthracnose and the yellowing and shedding of the lower leaves of the plant in the growing season is usually caused by the rotten root of the pot soil trifoliate orange.
