White crane taro, also known as bract taro, belongs to bract taro of Araceae. This foliage plant is a kind of green grass, native to Colombia, and is a popular indoor foliage plant in the tropical rain forest of Europe.
The leaves of white crane taro are similar to bamboo taro, and the flowers are similar to cranes, so pure and calm, auspicious and beautiful, innocent flowers are perceived by people. The auspicious meaning of the white crane taro species is particularly beautiful according to the image of its flowers. Because the white crane taro is beautiful, light, vigorous and resistant to shade, it is deeply favored by indoor greening and beautification.
morphological character
The stem or stem of the white crane taro is very short, the leaves are round or nearly lanceolate, and the flower base is round, that is, the flowers and petals are composed of white bracts and yellow-white meat spikes, which are shaped like palms, so they are named white palms; Flowers are obviously white or green with high branches and leaves.
Look at the variety
At present, there are nearly 30 species of white crane taro in the world, and 5 species have been introduced and cultivated in China, namely Hulk, White Palm of Perfume, White Palm of Magic Lamp, White Palm of Leaves and White Palm of Monaloa, each with its own characteristics, among which Hulk has attracted more attention because of its strong plant type.
Cultivation management
Generally, before new buds germinate in early spring, it is necessary to change pots, change pots, remove soil, trim roots, add new culture soil and plant pots, which is beneficial to the growth of roots. It is advisable to loosen the soil on the basin surface, keep the soil loose and breathable, and the temperature should be appropriate and safe.
land
Potted white crane taro requires loose soil, drainage and ventilation, the heavy soil should be sandy loam rich in humus, and the substrate should be prepared with the same amount of humus soil, peat soil and river sand around 1/4 or a small amount of perlite; Planting and adding a small amount of farm manure or bone meal or decomposed cake powder as base fertilizer.
water
White crane taro likes warm and humid, so it is necessary to supply enough water, keep the basin soil moist, avoid watering, and avoid water accumulation during the basin soil period, which is easy to cause rotten roots and plants to wither and yellow. In summer and dry season, it is necessary to spray water on the leaves with a fine-eye sprayer to improve the air humidity. The surrounding environment is too dry, and the new leaves turn yellow and fall off seriously. In late autumn and winter, we should reduce the amount of watering and keep the basin soil slightly wet.
illuminate
White crane taro is more tolerant to shade and suitable for semi-shade environment. Avoid direct sunlight. It needs about 60% scattered light, which can meet its needs. It should be cultivated indoors and in places with strong scattered light. Pay attention to shading 60% ~ 70% in summer. If the sun is too strong, the leaves will turn yellow and burn easily, and the withered leaves will be dull. If the light is too dim, plants will be strong and bloom easily. In northern winter, greenhouse cultivation will shade or less.
temperature
White crane taro likes high temperature planting and is afraid of cold. The suitable temperature is 20-28℃. Winter beard should be cultivated in high temperature greenhouse. The low temperature in winter night should be 10℃ to be safe. Winter white is 25℃. Low temperature or humidity in the later stage will easily lead to root rot, leaf shedding or severe browning, and the whole plant will die. Pay attention to cold protection and heat preservation in winter, and keep the basin soil moist.
Fertilize soil or land
Because it needs fertilizer quickly, it needs to apply 1 organic liquid fertilizer or dilute compound fertilizer or decomposed cake fertilizer and water every 7- 10 in peak season, which is not only beneficial to plant health, but also can prevent flower breakage. Fertilization should be stopped when the temperature is low in winter in northern China.
type
The propagation of white crane taro by plant sowing and tissue culture is due to the rapid propagation of plant germination and tillering.
1, plant propagation: about 2 healthy plants are combined in spring to change pots or sprout in autumn and early spring. Before the whole plant pot is poured out, the roots at the base of the old soil-cultivated plant cluster are cut several times, and each cluster contains three stems and buds. Re-potted with new culture soil, bring as many roots as possible to facilitate new plants, and new leaves will be drawn quickly and plump.
2. Seeding and seedling raising: breeding the difficult-to-bloom white crane taro, pollinating in greenhouse, harvesting and sowing when it is mature, and the sowing temperature should be about 25℃, so that the low-level plants are easy to rot and affect the seedlings.
