Breeding methods of Guangdong evergreen

Ramet method:

Generally, the tufted plants are divided into several plants with roots and planted separately in combination with basin change between February and March. It can also be planted in other seasons. After three years, it can be divided again.

Sowing method:

The broadcast is usually carried out between March and April. Sow in the flowerpot containing the culture soil, temporarily put it in the shade after watering, keep it moist, and germinate in about 25 days at 25-30 degrees. Adequate water supply is needed during the growing period, foliar spray every morning and evening in midsummer, stem and leaf growth slows down in winter, moisture should be controlled, and basin soil should not be too wet. The southern area is often maintained in semi-shady places in summer. During the peak growth period of stems and leaves from May to October, fertilization was applied once every semimonthly. Move indoors in winter, such as leaves yellowing, plus a diluted nitrogen fertilizer. After growing for several years, the mother plant is often creeping and its posture is poor, so it should be renewed by cutting.

Cutting method:

It can be carried out from May to June or September. Select a strong tender stem, cut a section 12-15 cm long from the top down, cut off the lower incision at 0.61 cm below the node, apply plant ash to prevent decay, dry and insert it into clean plain sand with a depth of 45 cm, put it in a hidden place, often keep the basin soil moist and maintain 80% air humidity. It can take root 34 weeks after insertion, and the root can be planted in a pot when the root grows to 23 cm.

The above is about the introduction of Guangdong evergreen is toxic and breeding methods, want to know more about Guangdong evergreen, please pay attention to the four Seasons Plant Network!

The breeding method of Guangdong evergreen: bright silk grass, also known as coarse rib grass, Guangdong evergreen, Guangdong evergreen, big leaf evergreen, well hay. Latin name: Aglaonema spp. It is a plant of the genus Araceae. Ramet and cuttage propagation are commonly used. Ramet propagation: when changing pots in spring. The plant is pulled out of the pot, the rhizome at the base of the stem is cut off, coated with plant ash to prevent decay, or left for half a day, and then potted after the incision is dry. Do not water too much after planting. Cutting propagation: it is suitable for spring and summer. A sturdy young stem with a length of 12-15 cm was selected as cuttings, and the top 2 leaves were retained and inserted into the sand bed to maintain high air humidity. The room temperature was 25-30 ℃, and rooting took place 20-28 days after cutting. Can also be inserted with water, scion can be slightly longer, 15 cm 20 cm is better, directly inserted in the glass bottle filled with clear water, change water every 2 days, about 15% 20 days can grow new root, root length 3 cm 4 cm potted. At the same time, in industrial production, the stem nodes were cut into small segments, but the internodes must be wrapped up with fresh water moss and put into the nursery box to keep the room temperature at 20: 25 ℃, rooting and sprouting from the stem nodes in about 20 to 25 days. The seed is used to propagate in the place of origin, it needs 25-28 ℃ to germinate at high temperature, and the germination rate is high. Culture methods of evergreen in Guangdong

The culture method of Guangdong evergreen, and the habit of Guangdong evergreen see: Guangdong evergreen

[Guangdong evergreen propagation] cutting, ramet, sowing, etc.

(1) Cuttage: from April to September. The stout stem segments of 10 cm to 15 cm in length were cut as cuttings. Keep the top 2 leaves, spread the cut with plant ash, dry slightly and insert into the seedbed. Keeping high air relative humidity and 15 X: temperature after insertion, it can take root and survive after 15-20 days. The stem without leaves can also be used as cutting material, but the rooting and sprouting is slightly slower than that of the top with leaves. It is also very suitable for water insertion and propagation, as long as the cut branches are inserted into the water, the roots can be sent out in more than 10 days.

(2) ramet: it is often combined with turning the basin in spring. After taking off the basin and mud, use a sharp knife to cut the plant into several clumps from the underground rhizome between the tufted stem, coat the cut with plant ash for antiseptic, or leave it in a cool place for half a day, wait for the wound to dry and plant respectively.

(3) sowing: it should be carried out at the high temperature of 25: 281: 1 in order to maintain a high germination rate.

[key points for cultivation of Guangdong evergreen]

(1) temperature: like warmth, the most suitable temperature for growth is 20-30 degrees. It is one of the most hardy species in Araceae foliage plants. As long as the temperature is higher than 0 degrees, you can survive the winter safely. It is not very resistant to high temperature, and the high temperature above 35 degrees is not conducive to plant growth, so measures such as shading, environmental water spraying and strengthening ventilation should be taken to reduce the temperature in summer.

(2) Illumination: like semi-overcast environment, avoid strong sunlight exposure, even if the strong light is direct for a short time, it will make the leaf surface burn and turn white and scorched. Excessive light will also make the leaves yellow and smaller and lose their luster. From May to September, shade should be provided to cover about 50% of the sun. Under semi-overcast conditions, the leaves are large and glossy, and show a beautiful tender green. Although it is extremely shady, even if the light is too dark, it will not grow too much, but its growth condition is not as good as that of plants under semi-shady conditions. You'd better get plenty of sunshine the rest of the time.

(3) watering: like the moist soil environment, extremely resistant to moisture but not drought. During the growth period, water should be fully supplied to ensure that the basin soil is not dry, but it is not suitable for stagnant water and waterlogging, and watering should be "wet and dry". In winter, watering needs to be controlled, as long as the basin soil is slightly moist. When the basin soil is too wet at low temperature, the leaves will turn yellow, and it is easy to cause rotting roots, and even lead to plant death.

(4) Environmental humidity: like humid environment. In the growing season, especially when the weather is sunny and dry, water should often be sprayed to the plant and its surroundings to maintain a moist environment, which is conducive to the luxuriant growth of the plant and more fresh and green branches and leaves. When the air is dry, the leaves will turn yellow, lose luster, and produce scorched edges.

(5) fertilization: like fertilizer, sufficient fertilizer can make leaves fat and bright, stem stout, and tiller exuberant. When there is a lack of fertilizer, the leaves become smaller, the plant grows poorly, and in serious cases, the lower leaves of the plant become withered and yellow and fall off. Nitrogen-based fertilizer should be applied every 15 to 20 days during growth. After autumn, if the plant grows vigorously, we should stop applying nitrogen fertilizer and appropriately increase the application of phosphorus and potassium fertilizer, so as to improve the cold resistance of the plant. Stop fertilizing in winter.

(6) turn the basin: the basin is often turned once every one or two years. Like loose, fertile, well-drained slightly acidic sandy loam, avoid heavy clayey soil. If the drainage is poor, the light plants grow poorly, and the heavy ones rot. The matrix can be prepared with rotten leaf soil, garden soil, perlite or rice chaff ash and other materials. After growing for many years, the old plant will be creeping and the shape of the plant is not beautiful, so it should be renewed by cutting.

(7) Prevention and control of diseases and insect pests: red spiders are easy to occur when high temperature is dry, so attention should be paid to prevention and control. Other diseases and pests include blight, leaf blight, mosaic disease, leaf spot, anthrax, root-knot nematode and so on.

[common problems in planting and raising evergreen in Guangdong]

The common causes of common problems are that the leaves are white and yellow, the smaller leaves are usually caused by excessive light, and the leaves at the base of the plant are withered and yellow and fall off because of the lack of fertilizer, so the ① basin soil is too sticky and has poor drainage. ② watering rotten roots are more likely to occur, especially when the basin soil is too wet in winter.
