Environmental requirements of white palm
White palm, also known as white crane taro, bracteate taro, trade name smooth sailing, belongs to Araceae bracteatum genus foliage plant.
Anthurium andraeanum, native to tropical America, has no stem or short rhizome, leathery leaves, long elliptic or broad lanceolate, long pointed, round base, dark green leaves with mercerization. The Buddha flame is leafy, similar to palm shape, higher than the leaf surface, white or green, flowers like crane, standing tall and graceful, white and flawless, giving people a peaceful and peaceful, plain sailing aesthetic feeling, the flame package has the ability to absorb formaldehyde, benzene, is a good indoor landscaping.
The potted plants are required to have symmetrical plant shape, erect leaves, green and bright green color, no damage, no disease spot, no pest parasitism, 3-5 spathe, 1-2 of which are in semi open state. It has large bracts, waxy luster, no diseases and insect pests, and fleshy inflorescences should be strong, straight and full of vitality. In the study and living room furnishings to set blue and white porcelain basin or purple sand basin, after purchase to use newspaper or plastic bag cover, to prevent the leaves from being blown by the wind, causing leaf injury, or dry sharp, burnt edge phenomenon.
White palm likes warm, humid, half cloudy environment, very resistant to weak light. The optimum temperature for growth is 20 ~ 28 ℃, the minimum temperature for overwintering is 10 ℃, and the suitable temperature for overwintering is 15 ~ 18 ℃. The substrate is suitable for loose, fertile, stable structure, not easy to rot, water and fertilizer conservation, pH 5.5 ~ 6.5.
Key points of aquiculture of Anthurium andraeanum to environment
The basin soil is composed of rotten leaf soil, peat soil and charcoal (or perlite) in the ratio of 5:4:1. The pot bottom is added with rotten stable manure or cake fertilizer as base fertilizer, 100-500g per pot. It prefers fertilizer. In the growing season, it should apply cake fertilizer water or liquid chemical fertilizer once every 1-2 weeks, and spray 0.2% potassium dihydrogen phosphate and 0.1% urea on the leaf surface. The seedling can increase the proportion of nitrogen appropriately, promote the growth and flourish, and the branches are dense. Too much nitrogen fertilizer in the adult plant will reduce the ornamental effect, and the fertilizer is generally stopped in winter.
White palm likes dampness and avoids ponding. It is watered every 5-7 days during its growth period. It is not as drought resistant as spring taro and bamboo. It is necessary to keep high air humidity (70% ~ 80%). Spray water frequently in summer. Cool boiled water should be used to prevent the leaves from leaving powder spots. Otherwise, the leaves will grow glass and keep the basin soil moist without ponding. Do not water the basin soil before the cold current Rotten roots and yellow leaves.
White palm likes scattering light, indoor display requires sufficient light, it is best to leave the window about 1 meter. Under the sunlight, the shading is 60% ~ 70% in summer, 30% ~ 40% in spring and autumn, no shading in North and 10% ~ 20% in South in winter. In summer, it should be placed in a semi overcast, cool and humid place. If it is placed in an air-conditioned room, water should be sprayed more. During the growing period, the temperature of Anthurium andraeanum should be kept at 25 ~ 30 ℃ in the daytime and 21 ~ 24 ℃ in the night. If the temperature is lower than 10 ℃ for a long time and the humidity is added, the root system will turn black and rot.
In winter, when the temperature is kept at 25 ℃ during the day and 15-18 ℃ at night, it will bloom and grow as usual. If there is no heating condition when the cold current comes, the plastic bag should be used to cover the whole plant. After the cold current, the cover can be removed. White palm is very sensitive to dichlorvos, trichlorfon, dimethoate and Omethoate, so it should not be used in insect control, but can be replaced by pyrethroids.
The root rot, dry tip and burnt edge are easy to occur in family cultivation. The reason is that the water is too much when the temperature is low, or the drainage of basin soil is not smooth when the temperature is too high. Dry tip and focal edge are mainly caused by too strong light and low air humidity. When high temperature is dry, spray water frequently on the leaf surface or the ground, or use 0.1% potassium dihydrogen phosphate to spray water instead of water to increase air humidity and increase nutrition.
