The latest culture method of Guanyinlian of Araceae

Araceae Guanyinlian, also known as black leaf taro, black leaf Guanyinlian, etc., is native to tropical Asia, likes warm, humid and semi-shady environment, must not be exposed to strong light, and is a unique foliage plant with a wide range of applications and high ornamental value. let's take a look at the breeding methods of Guanyinlian in Araceae and what problems we need to pay attention to!

The breeding method of Guanyinlian of Araceae

The main contents are as follows: 1. The method of sowing and reproduction: the seeds are collected after the plant is blooming and mature, and then the seeds are germinated under suitable warm temperature conditions to grow seedlings, which can be transplant after a little growth, which can be ignored. Although sowing and reproduction can be used, seeds are not easy to get.

2. Tissue culture seedling propagation: take the plant leaves and tubers as larvae, cut the leaves into small pieces and inoculate the whole group, first disinfect them with aseptic water, and then culture the seedlings with nutrient solution until the buds can become seedlings for transplanting.

3. Leaf insertion propagation: select a vigorous leaf in the plant and put it flat in the nutritious soil. After a period of time, the original leaf will grow new leaflet buds and roots, and transplant its roots in the soil for normal cultivation. Until it grows into a new plant.

4. Split propagation: generally, when the temperature is high in spring and summer every year, the plants with dense tillers of underground tubers are divided along the tuber separation place, so that each part has 2-3 plants, and then they are planted in the pot, and the roots are hurt as little as possible. At the same time, it is appropriate to place the basin in a humid environment, keep the basin soil moist frequently, and pay attention to foliar spray to facilitate the resumption of new plant growth. It can also dig out the underground tuber before the new buds grow in spring, separate the tuber segments, disinfect the wound with plant ash or sulfur powder, wrap it with water moss after slightly drying, or put it in loose soil with ventilation and drainage, so that it can grow adventitious roots and grow new buds. Don't get too wet in the matrix here, so as not to rot the tuber.

The Culture method of Guanyinlian of Araceae

1. Soil selection: Guanyinlian of Araceae does not have high requirements for soil, but it is suitable for fertile and loose sandy loam. Rotten leaf soil, coarse sand and vermiculite can be mixed at 2:1:1, and a small amount of plant ash and bone powder can be added as base fertilizer.

2. Fertilization method: the mature thin liquid fertilizer or compound fertilizer with low nitrogen and high phosphorus and potassium should be applied every 10 days or so in spring and autumn, the fertilizer and water should be light and not thick, too much fertilizer is easy to cause fertilizer damage, the content of nitrogen fertilizer in the compound fertilizer should not be too much, and too much is easy to make the plant grow. During the vigorous growth period, the dilute liquid fertilizer can be applied once or twice a month according to the growth situation, and the phosphorus and potassium fertilizer can be added to make the plant stem erect and grow strong. At the same time, it is beneficial to the growth and enrichment of underground tubers and cold resistance in winter. Foliar fertilizer is sprayed every half a month, and organic fertilizer or compound fertilizer containing nitrogen, phosphorus and potassium is applied once a month. More nitrogen fertilizer can promote the appearance of leaves. When fertilizing, use a fine nozzle spray pot to slowly irrigate along the basin mouth, do not splash the fertilizer liquid on the leaves, otherwise it is easy to burn the leaves.

3. Watering method: Guanyin lotus of Araceae likes to be wet and avoid stagnant water. Watering should be "no dry, no watering, watering thoroughly". During cultivation, the soil needs to be kept moist all the time. Drought will make the plant grow slowly, the leaf color dull, and lack of vitality, so it should be watered regularly. But at the same time, attention should be paid to prevent excessive water from causing stagnant water in the basin and causing root rot, so it is necessary to strengthen the drainage function of the cultivation medium. In order to prevent stagnant water, it can be considered to put a layer of coarse sand on the basin bottom as a drainage layer, so that the excess water can be discharged as soon as possible. When drying at high temperature, it is necessary to spray water to the surrounding environment and foliage to moisturize, which can make its growth more exuberant. Watering should be reduced in winter.

4. Temperature requirements: Araceae Guanyin lotus prefers to be cool and cold-tolerant. Spring and autumn are the main growing periods, while summer and winter are mainly dormant periods. When summer is hot and humid, it is easy to cause plant rot because of muggy heat and humidity, so it should be properly shaded, ventilation conditions should be improved, cooling measures should be taken, and the basin soil should be moderately dry. When the winter temperature is above 15 ℃ during the day and 5 ℃ at night, it can continue to grow. It can be maintained normally, but at a lower temperature, if watering can be controlled, it can also withstand the low temperature of 2 ℃, dormant below 20 ℃, overwintering temperature is generally above 15 ℃, and leaves below 10 ℃ will suffer frost damage until withered, so it should be planted indoors in winter.

5. Lighting requirements: it is appropriate to have sufficient sunshine, it is best to be cultivated in outdoor sunshine all the time, and sufficient sunshine is needed during the growth period. if sufficient sunshine can be guaranteed, the plant shape is compact, the leaves are thick and full, and the leaf color is beautiful, although it can grow normally in the semi-shade. but the ornamental value is greatly affected, many varieties are prone to plant shape loose, not compact phenomenon, summer should avoid hot sun exposure, need appropriate shading. Negative is very strong, suitable for growing in the shade of scattered light, avoid direct sunlight, generally summer and autumn should be shaded, otherwise the leaf surface is rough, the leaf color is gray, sometimes burn spots occur, but more sunshine is better in winter.

6. Management of the four seasons

① management in spring: change the basin when the temperature is stable above 15 ℃ in spring, change the basin when dormant in winter, first remove the dormant tuber from the basin, cut off the rotten roots on the dormant tuber, plant it in the basin, plant it in the basin, plant it in a depth of about 2 cm of covered soil, properly watering (water should not be much, moisture is partial to the degree), fully water the leaves after they are unearthed, and then cut off some of the old leaves when changing pots that are not dormant in winter.

② summer management: Araceae Guanyin lotus likes high temperature and high humidity environment, summer is its peak growing season, should keep the basin soil humid, cloth placed indoors pay attention to supplement indoor air humidity, adequate fertilization, not suitable for air-conditioned room.

③ autumn management: after the temperature is cool in autumn, it can be gradually moved to a place with morning and evening light to cultivate, keep the basin soil moist, spray water around it and leaves several times a day, and stop fertilization. With the decrease of air temperature, the water supply should be gradually reduced to make the basin soil dry. After the temperature dropped below 15 ℃, the aboveground part gradually wilted and entered dormancy, such as the indoor temperature could be kept above 18 ℃ in autumn and winter, and the plant could grow slowly and not dormant.

④ winter management: Araceae Guanyinlian is not tolerant to low temperature, and its tubers are dormant when the temperature is low in winter. Pot plants should be placed indoors above 10 ℃ for overwintering. The pot soil should be kept dry but not dry. When the humidity of the basin soil is high, the tubers are easy to rot. If the indoor temperature is maintained above 18 ℃, not dormant, still ornamental, it should be arranged on the windowsill with morning and evening light, keep the basin soil moist, and often spray around its leaves to improve air humidity, especially when indoor air conditioning is used, more attention should be paid to the supplement of air humidity.

Matters needing attention of Guanyinlian of Araceae

The main results are as follows: 1. the plant has a high demand for fertilizer, and it should be fertilized every 10 to 15 days in the growing season, and it is better to use organic fertilizer or ternary compound fertilizer alternately, and more nitrogen should be applied in the growing season to promote the beauty of leaves.

2. The optimum temperature for plant growth is 20 ℃ ~ 26 ℃, and dormancy occurs when it is lower than 20 ℃. If the temperature is too low, it is easy to cause plant death. Spring and summer, exuberant growth, requires high air humidity, if you can sprinkle water on the ground or spray foliar, the growth is better. It can survive the winter naturally in the tropics, and in the subtropical and temperate regions, due to the low temperature in winter, the greenhouse should be used to keep warm and overwinter. the amount of water should be controlled in winter, as long as the leaves do not show a soft sagging shape.

3. The cultivation of the plant is more than in spring, and the basin soil requires good drainage, and the rotten leaf soil or sandy loam rich in organic matter should be changed in late winter and early spring.

4. The plant is vulnerable to aphids. It can be sprayed with 40% dimethoate or 50% malathion EC 1000-1500 times, or 1500 times with 80% dichlorvos EC.

5. The plant grows well in the warm, humid and semi-shady environment. In summer and autumn, the plant should be placed in a shady place, such as Reed curtain or tree shade, avoid direct sunlight, plant growth requires higher air humidity, humid climate conditions are conducive to plant growth and leaf moist, if the environment is too dry, it is easy to cause leaf scorched edge, affect the plant beauty, the air relative temperature should be 60% 80%, at 15 ℃, the growth will stagnate. Go into dormancy.

6. The plant can be fertilized once every 15 days during the growing period from May to October, and the thin fertilizer solution is safer. In winter, sufficient light and good ventilation should be maintained, watering should be strictly controlled, and the basin soil should be slightly drier. Indoor cultivation in winter should prevent high temperature and stuffy heat or poor ventilation to prevent the occurrence of diseases and insect pests, and stop fertilization in winter.

Note: the whole plant of Araceae Guanyinlian is poisonous, with the stem the most poisonous, itching caused by skin contact with juice, blindness caused by eye contact with juice, itching of tongue, throat, swelling, salivation, gastrointestinal burning, nausea, vomiting, diarrhea, sweating, convulsion, severe suffocation, heart paralysis and death. For general family planting, what needs to be paid attention to is the toxicity of Guanyinlian of Araceae. Try to avoid planting in families with children. Care should also be paid to prevent children and people who do not know from eating by mistake or ingesting through other channels.
