How to cultivate, maintain and reproduce green pineapple?

Green radish is perennial evergreen vine. Stems and tendrils are thin and soft, internodes have aerial roots, leaves are heart-shaped or long elliptic, long irregular, golden stripes or stripes, thick and bright, entire.

Green radish likes warm, shade, cold, in fertile, loose sandy loam and moist environment grow well. Therefore, cultivation and management should pay special attention to meeting these characteristics.

(1)Cultivation. There are two types of potted plants: one is a column potted plant, and the other is a common potted plant. Pot soil should be selected rotten leaf soil or peat soil, garden soil, coarse sand mixed into culture soil, planted in warm spring, planted in the shade, slow seedlings after moving to semi-shade maintenance. Young plants change pots once a year and adult plants change pots once every two years.

(2)Conservation. Light and temperature. Green radish shade tolerance, can be placed all year round in indoor culture, can also be placed in the outdoor semi-shade. Put indoors, in spring, summer, autumn three seasons should be placed in the east, west or north of the window, winter should be moved to the south window near to prevent cold wind blowing, as much as possible to see the sun. Can not be placed in the dark for a long time, otherwise the stem tendrils long, loose plant shape, leaf color pale, lose ornamental value. Put it on the outdoor balcony. Do not let the strong light direct, should be placed in a semi-shady place, especially in summer to shade, or put the north sun (window) platform. The growth temperature of green radish is 20 to 30℃, outdoor cultivation in winter must be kept above 15℃, not lower than 10℃, otherwise vulnerable to freezing damage. Water, fertilizer and humidity. Green radish likes to be moist, and the soil in the basin should be kept moist during the growth period, but it should not accumulate water. Dry leaves are easy to yellow, ponding will rot roots. In summer, we should water more, spray water on leaves and surroundings, increase air humidity, and control watering in winter. Nitrogen and phosphorus mixed liquid fertilizer or compound fertilizer is applied once every 2-3 weeks in the growth season. 3. Proper pruning. Branching too much or yellow leaves found, can be properly pruned to maintain the plant shape beautiful. 4. Remove diseases. Green radish often due to poor ventilation and other reasons, leaf spot disease and root rot, should remove the diseased leaves, with 50% carbendazim wettable powder 500 times spray or root irrigation.

(3)reproduction. Green radish easy to reproduce, cutting spring and autumn can be carried out. Healthy stems are selected, cut into 2-3 sections, inserted into plain sand or peat soil, watered thoroughly after insertion, placed in semi-shade, sprayed with water 1-2 times a day to keep the substrate moist, and rooted and germinated in about 3 weeks at 25 DEG C. Can also be used stolon buried in the soil, aerial roots can take root in the soil, to grow new tender leaves, cut open section by section, sub-planting pots can be.

Family Cultivation and Conservation of Green Rose

Family genus: Araceae, green radish

Other names: golden kudzu, devil vine

Tropical rainforest native to Indonesia, Solomon Islands.

(1) Morphological characteristics: perennial evergreen vines. Stems and leaves are fleshy, stem nodes with aerial roots. Leaves alternate, ovate long elliptic, heart-shaped, waxy, 10~15 cm long, dark green leaves, bright. varietal having flowers mottled with irregular golden stripes or spots.

The main cultivars are:

E.a.' Marble Queen: Leaves with milky white markings, thicker than the original variety.

E.a.' GoldenPothos: Irregular yellow streak on leaves.

E.a.' Tricolor s leaves have green, yellow and creamy white markings.

(2) Habits: Love warm and humid. Likes light also bears half shade, likes loose fertile cultivation substrate.

(3) Cultivation and management: Green radish is strong and can be potted indoors all the year round. It can be placed in a bright place in the basin for a long time. If long-term in the shade, it will make the leaves smaller, internodes longer, for the color of the leaf varieties will be diluted, affecting the ornamental value. Summer should be spent in a semi-shady environment, avoiding direct sunlight.

The suitable temperature for growth is about 25℃ during the day, and the suitable temperature in winter should be kept at 10~13℃, generally not lower than 7℃. South China and Southwest winter warm areas can be open field cultivation.

Green radish likes hot and humid environment, so it needs to spray water on leaves and ground frequently and keep basin soil moist. Compound fertilizer is applied every 2 weeks or so during the growing season.

Often potted, can also be used as a basket, or planted in indoor planting slots. General pot and then stand to support, so that its vines climb on it, it is best to use with moss dead wood or snake wood (tree fern trunk), can also be used to make cylinder planting wire. If planted in hanging baskets or planting slots, generally let its stems hang freely, do not have to erect brackets. It is usually replaced once every 2 - 3 years. In May to June every year, proper pruning and renewal are carried out to promote the germination of new branches on the basal stems and make the bushes more luxuriant. Cultivation soil to decayed leaf soil, garden soil mixture is good, hydroponics can also grow.

(4) Propagation: It is not easy to bloom, and it is commonly used for cuttage propagation. From May to July, the buds at the top or base of the stem are cut into a section of about 10 cm, inserted into a propagation bed mixed with equal amount of fine sand and peat, maintained at a proper humidity and temperature of 21~25℃, and new roots can be produced in a semi-shady environment for about 3 weeks. After rooting, it can be potted, with 3~4 plants per potted plant. Can also be used older branches cuttage, with bud eye branches, cut into 4~5 sections of a section, according to the above method inserted, can also grow into new plants. It can also be propagated by layering, which can be carried out during the growth period.

Green radish breeding and maintenance skills Propagation by cutting. Stem and leaf cuttings can be used for propagation. In spring and autumn, two sections of stem with length of 15~30cm are cut as cuttings, 1~2 leaves at the base are removed, the incision is smoothed, and roots can be rooted by inserting into plain sand. Leaf insertion method, with a clean sharp small blade, cut the upper healthy leaves, wash with clean water, put in a cool place for several hours, make the incision slightly dry, then insert the petiole base into clean water, put in shade after insertion, generally change water every 3~5 days, about 1 month can take root. It is easier to take root with sandy soil as cutting substrate. Sterilize sand before cutting and keep soil and air moist regularly. Rooting and germination took place in 3 weeks at temperatures above 25℃ and in a semi-shady environment, and new plants emerged.

It can also be propagated. It can be carried out in a sand basin, and the green radish stolon in the basin can be pressed with soil or sand. After the air roots are rooted in the soil, they can take root. When new leaves grow, they can be cut and planted separately.

[Cultivation Management]

Potted appropriate selection of loose, breathable, good drainage soil, can be mainly decayed leaf soil, plus 2-3 garden soil mixed or mixed with peat soil and pearlite modulation. Green radish strong, can be four seasons in indoor potted, placed in bright indoor sunlight, can be placed for a long time. If it is placed in the dark for a long time, it will make its leaves smaller and its internodes longer, which will affect its ornamental value. Can also be moved to outdoor semi-shade after warm spring, late autumn and then moved into indoor management. It should be placed indoors in a bright place with little direct sunlight. In the dark room, the growing leaves are small and the internodes are long, usually 2 to 4 weeks should be moved to a place with strong light to resume planting. Likes the hot and humid environment condition, needs frequently to the leaf surface and the ground sprinkles water and keeps the basin soil moist. Summer must be spent in a semi-shady environment. Winter room temperature should not be lower than 15℃, otherwise poor growth. The climate in spring and winter in northern China is relatively dry. In addition to keeping the basin soil moist, it is necessary to spray water on the leaves frequently and scrub the dust on the leaves. In order to keep the plants growing vigorously, it is generally possible to apply complete fertilizer once every 3 to 4 months. Compound fertilizer is applied once every 2 weeks or so during the growing season. In May to June every year, green radish should be pruned and renewed to promote the germination of new branches on the basal stem.

Green radish has the characteristics of wet heat, optimal growth temperature between 20℃ and 30℃, adaptable temperature above 65℃, etc., but the north does not have these conditions in autumn and winter. Therefore, the maintenance in autumn and winter has become a crucial link in the growth cycle of green radish. In winter, it creates a comfortable growth environment as in summer, which can keep green radish flourishing all the time.

The following aspects must be paid attention to when maintaining:

1. Light: The original growth condition of green radish is in the forest covered by towering trees, and the positive is not strong. However, in autumn and winter in the north, in order to supplement the lack of temperature and photosynthesis, it should increase its illumination. The method is to place the green radish in the best place for indoor light, or move to a sealed balcony at noon to bask in the sun. At the same time, windows should be opened as little as possible when the temperature is low, because the leaves may be frostbitten in a very short time.

2, temperature: in the north, room temperature above 10℃, green radish can safely winter, room temperature above 20℃, green radish can grow normally. General family to reach this temperature problem is not big, need to pay attention to is to avoid excessive temperature difference, but also pay attention to leaves do not close to heating equipment.

Humidity: refers to the moisture content of the air in the plant growth environment. Under normal temperature conditions, increasing humidity is extremely beneficial to plant growth. There are several ways to increase the temperature. Bring the plant close to the humidifier, the humidifier is open for more than 5 hours every day, and the plant can enjoy the mist sprayed by the humidifier; spray water on the leaves, stems and aerial roots of the plant with the sprayer adjusted to the mist scale several times a day; keep a proper amount of water in the flowerpot tray, and increase the local temperature of the plant through its evaporation; wipe the leaf surface lightly with cold wet towel or toilet paper or apply the leaf surface lightly in a short time (1-2 hours a day); The transparent plastic film cover on the plant, creating a small greenhouse effect, through evaporation of moisture in the soil to supplement the water of the plant, no more than 2 hours a day, too long will affect the ventilation and photosynthesis of the plant.

Water: The amount of watering in autumn and winter should be strictly controlled according to room temperature. Before heating, the temperature is low, the soil evaporation of the plant is slow, to reduce watering, the amount of water should be controlled between 1/4-1/2 of the original. Even after heating, watering should not be too frequent, watering should be less poured into the basin, should be brown silk seepage. In addition, water should also be sprayed on the aerial root growth of the palm column to reduce the root water shortage caused by too fast evaporation. Winter irrigation water to dry after a day of water is better, water too cold easy to damage the roots.

Fertilizer: In the autumn and winter seasons in the north, plants grow slowly or even stop growing, so fertilization should be reduced. Before winter, liquid inorganic fertilizer is mainly sprayed, and the time is about once every 15 days. After winter, the fertilizer is mainly sprayed on the leaves, mainly through the stomata on the leaves, and the fertilizer is absorbed through the stomata on the leaves. The fertilizer efficiency can be directly applied to the leaves. Foliar fertilizer to use special fertilizer, ordinary inorganic fertilizer is not easy to be absorbed by foliage. Peking University flower god series and Japan produced a flower can be used as foliar fertilizer.

Green distemper pile: green distemper does not bear seeds, buy from a florist or cut some tender and strong seedlings from relatives and friends to survive. After sprouting, green radish can be added. The green radish column has the function of fixing and supporting the growth of green radish, and at the same time can provide necessary water. Usually used as a green radish pile into the basin, slightly buried some soil, with a wooden stick tower into a triangle to make it fixed, and then buried in the soil, because it is also long plants, soil is not easy to be too much. Take the sprouted green radish seedlings inserted into the soil, generally speaking, the more dense the green radish seedlings grow out of the pot, the better they look, a pot should be planted about 4-5 plants. Tie the seedlings with thread while fixing them on the brown column. Water the brown column and keep it moist. After a few days, the aerial roots of green radish will take root and grow in the brown column. The time to add green radish column is better at the turn of spring and summer. In winter, the temperature is low and the seedlings are easy to be injured. When adding columns, we should pay attention to grasping the temperature.

Green radish is an aerial root plant. The lower part of the stem between the leaves has thick fleshy aerial roots, which can be potted or hung. At the same time, it can also be coiled into flower baskets, columns, balls and other forms to change its viewing effect.
