Drip-dropping Guanyin (Araceae plant)

Edit

Drip-dropping Guanyin, Araceae, Alocasia genus, also known as Dripping Water Lotus, Guanyin Lotus, Bergamot Lotus, etc. , called aunt taro in Taiwan, native to South America, is a common ornamental plant in tropical and subtropical areas, commonly known as scar taro, wolfsbane (Guangdong), wild taro, mountain taro, big root taro, big insect taro, Tian Yu, Tianmeng, etc., as When viewing the plant, it is called Dripping Water Guanyin. It is a perennial evergreen herb with medicinal value. The bulbs and leaves can be used medicinally, but they are poisonous. The leaf juice will be poisonous when ingested. Under warm and humid conditions with sufficient soil moisture, water will drip downward from the leaf tips or leaf edges, and the flowers will resemble Guanyin, so it is called Dripping Guanyin.

1 Editing of morphological characteristics

It is an upright perennial herb with a plant height of 2M. It has fleshy rhizomes underground, long petioles, broad leaf sheaths, large leaves, shield-like broad arrow shapes, clustered stem tops, pointed ends, wavy edges, and obvious main veins. The spathes are yellow-green and the spathes are inflorescences. [1]

The above-ground stems are thick, sometimes 2-3 meters high, and the whole plant can reach a maximum of 5 meters. The creeping rhizome is 5-8 cm thick, cylindrical, segmented, and often bears adventitious buds. There are many leaves,

helically arranged; the petiole is thick, up to 1.5 meters long, the lower half is sheathed, and the base is 5-10 cm wide with the sheath; the leaves are leathery, with a slightly bright surface, green, and a back. Lighter, very broad, arrow-shaped and ovate, with shallowly wavy edges, 50-90 cm long, 40-80 cm wide, the front lobe is wide and ovate, with the first dripping Guanyin Picture collection (19 photos)

The ends

acuminate, almost equal in length and width, the posterior lobes are semi-oval; the length is about 1/3 of the anterior lobes, and the base joint is shorter. Curved and lacking a round shape, the posterior basal veins are at right or acute angles to each other; the anterior lobe has 6-10 pairs of grade I lateral veins, slightly wider.

Inflorescence stalks 2-3

Clustered, cylindrical, each covered with bracts (scale leaves) 50 cm long and 8 cm wide, the latter being lanceolate and green; the inflorescence stalk is long (12- ) 50-60 cm, light green. The tube part of the spathe is swept into a round oval shape

or egg-shaped, white-green, 3-5 cm long and 4 cm thick; the eaves are white-green, yellow-green, then turn white, boat-shaped, Oblong, slightly pointed at the apex, slightly downward curved, (10-) 20-30 cm long, spread wide (4

-) 5-8 cm. [1]

The spadix is ??fragrant: the female inflorescence is cylindrical, (2-) 3-4 cm long, the sterile male inflorescence is (2.5-) 5-6 cm long, and attenuates into a fertile male inflorescence. ,

The latter is 3-7 cm long; the appendage is conical, creamy yellow, with a thick base, 3-5.5 cm long, 1-2 cm thick, with a blunt apex and embedded with irregular grooves. . Female flowers: ovary prismatic, apex tapering into an obvious column, stigma disc-shaped, ovule oval, basal embryonic seat. Sterile male flowers are flat and hexagonal at the top. The berries are bright red, short egg-shaped, about 1 cm long and 5-9 mm in diameter. The flowering period is from April to July, and can also bloom under warm and humid conditions. [2]

2 Growth Habits Editor

[3] If

the air and humidity are too low, the water will evaporate immediately, so Generally, there is more dripping in the morning, which is called "vomiting water" phenomenon (this phenomenon is not limited to calla lilies). The flowers bloom like Buddha flames and belong to the "Buddha flame flower sequence". It is an ornamental flower plant that likes warmth, moisture and sufficient sunlight. It generally blooms in winter and spring. The dormant flowering period is from November to May or June of the following year, and the full flowering period is from February to April.

1. The growth temperature is 20-30℃, and it can withstand low temperatures of 8℃. In high temperatures in summer, just keep the soil moist and spray water frequently. , it can still grow normally under shade, and the room temperature in winter should not be lower than 5℃. Dripping Guanyin is an understory plant in tropical rain forests, so its growth requires high humidity and scattered light.

2. Shade-tolerant plants prefer a semi-shady environment and should be placed in an environment that provides both shade and ventilation.

3. It particularly likes moisture. During the growing season, not only the pot soil is required to be moist, but also the air humidity is required to be no less than 60. When the temperature is high in summer, water spraying should be strengthened to create a relatively cool and humid environment for it. If it is placed in an indoor air-conditioned hall, it is necessary to ensure that the pot soil is moist and the leaves should be sprayed with water from time to time. If the room temperature cannot reach 15°C in winter, watering should be controlled, otherwise it will easily lead to plant root rot. Generally, spraying warm water once a week can keep the leaves dark green.

4. Nutrient soil mixed with leaf mold, peat soil, river sand and a small amount of soaked cake fertilizer can be used for cultivation. Hydroponics can also be used, but attention should be paid to preventing root rot and adding nutrient solution. Usually, the pot is changed once a year in spring, and the soil can be loosened once a month to keep the pot soil in a transparent and good condition.

5. It prefers fertilizer. Liquid fertilizer should be applied every half month from March to October. The proportion of nitrogen can be appropriately increased. It would be better if a little ferrous sulfate can be added so that the leaves will grow. It is as big as a lotus leaf, smooth and pleasant. Fertilization should be stopped when the temperature is below 15°C.

6. Because Dripping Guanyin is a foliage plant, if it is not properly planted and maintained, the largest leaves will turn yellow and dry. At this time, they should be cut off together with the stems with a knife, otherwise It will affect the growth and ornamental appearance of other leaves.

7. The white juice in the stem of Dripping Guanyin is poisonous, and the dripping water is also poisonous. Accidental contact or ingestion of the juice will cause discomfort in the throat and mouth, and in severe cases, suffocation, leading to cardiac paralysis and death. . Skin contact with its juice will cause itching or strong irritation. Eye contact with the juice can cause severe conjunctivitis and even blindness. Therefore, contact with Dripping Guanyin should be minimized. It is best not to plant it in families with children.

3 Distribution range editor

It is abundant in tropical rainforests and wild banana forests at an altitude of 200-1100 meters in the south-central, western and southeastern parts of Yunnan Province. It is also found in Sichuan, Guizhou, Hunan, Jiangxi, Guangxi, Guangdong and coastal islands, Fujian and Taiwan.

Abroad, it is distributed in Bangladesh, northeastern India (Kasi Mountains), Laos, Cambodia, Vietnam, Thailand and the Philippines. [2]

4 Variety Classification Editor

Dripping Guanyin, Angiosperm, Alismatales, Araceae, Alocasia genus. The scientific name is Alocasia chinensis, also known as "Guanyin lotus" and "Mimosa grass" in ancient times. It is a perennial evergreen herb with medicinal value. [1]

5 Cultivation Technology Editor

Soil Planting Technology

Production standard: 20cm pot: height 20-30cm, crown width about 25cm, number of leaves 6- 7 pieces/plant 4 months

Substrate preparation: a mixture of loose, well-drained and aerated domestic peat, 2:2:1 pond mud, peat soil, and coarse sand, plus a small amount of well-drained Cultivation in nutrient soil mixed with cake fertilizer, add peat to water and mix well (standard for adding water: after adding water and mix well, hold a handful of peat in your hand and water seeps out from between your fingers) and wait for planting.

Pot: For reused old pots, they must be soaked in 2000 times potassium permanganate solution for more than half an hour, then rinsed with clean water and dried for use. Large potted plants are generally planted in 20cm size pots. When planting, first place about 4cm of substrate at the bottom of the cup, and then move the screened seedlings into the cup. Small seedlings should not be planted too deep, and it is appropriate to level the base of the plant; Moderately tight, fill the cup until it is 8 minutes

full, 2-3 plants/pot. [4]

Hydroponics method

Hydroponics dripping Guanyin can be converted from soil-grown plants into hydroponics by root washing. Care should be taken when washing the roots, and please do not damage them. Tubers and roots should be cut off at the same time as rotten roots and aged roots. If the tuber has no roots, it should be placed in a shaded place to dry for 2 to 3 days. After the wound is dry, it can then be immersed in water. New roots will appear after 2 to 3 days.

In the early stage of hydroponics, the water should be changed every 2 to 3 days. The water depth should be 2/3 of the root system. New roots will grow after 3 weeks. After 3 weeks, the hydroponic plants will adapt to hydroponics. After the environment, change to nutrient solution culture. After that, change the nutrient solution every month or so.

Because the stem tissue of Dripping Guanyin is relatively loose, if the water quality is poor, it is easily contaminated, causing root rot and stem rot. Therefore, it is necessary to

Keep the bottle of water clean, and at the same time, wash the tubers and roots by changing the water or nutrient solution. of mucus and cut off the rotten roots. [5]

Dishui Guanyin is a very common domestic green potted plant, but because it is a tropical plant, it generally does not bloom in the north. But if the temperature and other conditions at home are suitable, they will bloom.

It does not have high soil requirements, but grows best in sandy loam or humus loam that is well-drained and contains organic matter. Since Dripping Guanyin likes a warm, humid and semi-shady environment by nature and is not cold-tolerant, the pot soil must be kept moist during the growing season. But it can tolerate a little drought, so don’t abuse it too much. [6]

In summer, the flower pot should be placed in a semi-shaded and ventilated place, and water should be sprayed around and on the leaves frequently to increase air humidity, lower leaf temperature, and keep the leaves clean.

Since Dripping Guanyin grows very fast, it prefers fertilizer. Apply nitrogen, phosphorus, and potassium compound fertilizers 1-2 times a month (the proportion of nitrogen can be appropriately higher). If you can apply a little sulfate, Iron will make the leaves larger and greener, and long-term fertilizer deficiency will easily cause the lower end of the stem of Dripping Guanyin to be hollow and bald, affecting the ornamental value. When the temperature drops and enters the dormant period, fertilization can be reduced or eliminated.

If you want to keep the dripping Guanyin indoors small and exquisite, you only need to wait until its seedlings grow to about one foot and are suitable for home display, and immediately spray the whole plant with 2 paclobutrazol solution, and then The stems and leaves that grow again are no more than 40 cm high, and the leaves are thick and have high ornamental value. Spraying once every six months or so can play a good role in height control. [1][3]

Notes

Temperature

Dripping Guanyin can grow well in an environment not lower than 18℃. If the temperature is lower than 18 ℃, Dripping Guanyin will be in a dormant state and stop growing.

Fertilization

Dripshui Guanyin likes fertilizer, so fertilize it every month.

Watering

Dripping Guanyin should be watered more in summer, but not excessively. It should be dry and wet when appropriate. There should be no accumulation of water in the soil, otherwise the tubers will rot. In winter, they should go dormant, water less, and stop fertilizing.

Sunshine

Dripling Guanyin prefers shade and should not be exposed to direct sunlight. The main reason why Dripping Guanyin becomes "wilt" is because of insufficient fertilization. Pay attention to top dressing

[1][7]

Propagation method

Split and sow

Every summer and autumn, alocasia tubers will sprout small alocasia with leaves, which can be divided by repotting and changing soil. When the fruits are ripe in autumn, the orange-red seeds are harvested and sown as they are picked, or dried and stored for sowing in the following spring. [3]

Cutting propagation

For perennial old plants, it can be combined with the renewal of the plant. Propagation by dry cuttings.

The benefits of stem cutting

Firstly, because the plant loses its top growth advantage, nutrients accumulate at the base and cause a large number of roots and stems to germinate, which contributes to the reproduction speed and amount;

Second, the intercepted old stems can be cut into branches with a length of about 15 cm, placed in the shade to dry for half a day, and then inserted into sandy loam soil for cultivation. Especially for the growing section at the top, cut off all the formed leaves and put the plant directly into the pot. Cutting and cultivation are carried out simultaneously. After two months of cultivation, a pot with huge leaves, tight branches and short height will be ready. The strong and vigorous mature plant has a certain elegance when placed indoors. Cut dried calla lilies

Suitable in spring, summer and autumn. During the cutting period, the moisture of the substrate (6 parts sand: 4 parts garden soil) should be maintained, and the air humidity should be increased. Many strong roots will grow in about 7-10 days. During the cultivation of old plants, due to the shady environment

or spraying water on the leaves every morning and evening in summer and autumn, a few new plants will occasionally sprout on the old stems (especially those left after cutting and drying treatment). (on the lower stem base), and there are many attached aerial roots, which can be broken off from the junction of the daughter plant and the mother plant

Plant it in a pot. [1][3]

Precautions

The white sap in the stem of Dripping Guanyin is poisonous, and the dripping water is also poisonous. Accidentally touching or ingesting its sap will cause indigestion. Discomfort in the body and mouth, burning sensation in the stomach. Special attention should be paid to preventing accidental ingestion by young children. But Dripping Guanyin is not a carcinogenic plant.

Winter maintenance

Conservation: Dripping Guanyin likes a warm, humid and slightly shaded environment, but it needs to be sunny during the flowering period, otherwise the spathes will be green and the quality will be affected. It is necessary to ensure 3-5 hours of light every day, otherwise the petioles will elongate and affect the ornamental value. Dripping Guanyin is not very cold-tolerant and needs to be moved to the greenhouse in mid-October. In summer, it is necessary to spray water frequently to cool down and moisturize under shade conditions.

Dripling Guanyin likes moist and fertile soil, which is often called "big fat and big water". It needs to be watered more during the growth period. Top dressing can be applied alternately with liquid fertilizer such as decomposed bean cake water and chemical fertilizer (compound fertilizer or diammonium phosphate), once every 2 weeks. When applying liquid fertilizer, be sure not to pour the fertilizer water into the leaf sheaths to avoid rot. Use of ferrous sulfate

In potted dripping Guanyin, top-dressing ferrous sulfate can make the leaves of dripping Guanyin larger, thicker, greener, smoother and shiny, and the petioles are less likely to elongate, thus ensuring the beautiful appearance of the leaves. . At the same time, it can promote the formation of flower buds and extend the flowering period. The specific method is: dilute ferrous sulfate into a solution of 2, and pour it every one month, and pour it thoroughly every time.

Disease and Pest Control

Diseases of Dripping Guanyin are reflected on the leaves. There are generally two types, one is leaf spot and the other is anthracnose. For leaf spot disease, you can spray chlorothalonil or carbendazim 800 times on the leaves 2-3 times in a row, every 7 days. Anthracnose must be sprayed on the leaves with 500 times of thiophanate methyl 75, once every 7 days, 2-3 times in a row, and it can basically be controlled. Because Dripping Guanyin is a foliage plant, once the leaves become sick, it will inevitably affect its ornamental effect, so prevention should be the priority.

There is a kind of blight disease reflected on the stems.

It is caused by bacterial infection. This disease is not easy to detect at first, but it will be very serious once discovered.

If you find that the stem is tilted to one side or has wilting spots, it must be infected with Fusarium wilt. You can use a knife to cut off the diseased area. The boundary between the diseased area and the non-diseased area is very obvious. Generally it can be broken off by hand. If the diseased area is less than one-third of the stem, you can apply a layer of chlorothalonil solution to the non-diseased area and keep it dry. Apply it again every ten days. You can basically recover after 20 days

.

The most serious insect pest of Dripping Guanyin is mites, commonly known as red spiders. Spider mites usually live on the underside of leaves. They not only suck the nutrients from the leaves, but also spread various viruses, seriously affecting the growth of plants. Therefore, you must check frequently and treat immediately if found. Drugs such as Mite Cleaner, Mite Cleaner, and Imidacloprid can be used for treatment. [1][3]

Causes of yellowing of leaves

Dishui Guanyin is native to the humid tropical rain forests of Southeast Asia. It likes

scattered light and does not like direct sunlight. , it should be placed in a semi-shady and semi-sun shaded place in spring and autumn, in a shady place in summer, and indoors in winter. If the sun is too strong, the leaves will be burned and turn yellow. However, "all things grow by sunlight". If they are placed in the living room, bedroom, etc. for a long time, due to insufficient or no light, it will affect the growth and morphology of the plants. Under these conditions, the internodes of the plant body will Especially long, the leaves are underdeveloped and small, lacking chlorophyll and appearing yellow; in addition,

Dripling Guanyin likes high temperature and high humidity. Appropriately add some fertilizers and pay attention to watering more to increase its resistance to the environment. , can also keep the leaves greener.

For Dripping Guanyin, keep the pot soil moist. You can expose the roots a little. When the pot soil is dry, water it thoroughly. If the leaves turn yellow, cut them off at the base, being careful not to damage other leaf diameters. [8]
