The culture method of hydroponic white palm

White palm, also known as bract taro, plain sailing, lily intention, etc., is a perennial herb of the Araceae family, with emerald green leaves, white Buddha bracts, very fresh and elegant, has a very good ornamental value, and can filter indoor waste gas. it has a certain cleaning effect on ammonia, acetone, benzene and formaldehyde, so let's take a look at the cultivation method of hydroponic white palm.

The growth habit of White Palm

White palm likes high temperature, humid and semi-overcast environment, is more sensitive to humidity, is afraid of strong light exposure, summer shade 60% 70%, but long-term lack of light, it is not easy to blossom. The soil should be rich and humus-rich loam. The suitable temperature for growth is 22: 28 ℃, 24: 30 ℃ from March to September, 18: 21 ℃ from September to March of the following year, the winter temperature is not lower than 14 ℃, the temperature below 10 ℃ hinders the growth of plants, and the leaves are vulnerable to freezing injury. White palm in the process of storage and transportation, the temperature is controlled at 13: 16 ℃, the relative humidity is 80: 90%, and can withstand the dark environment for 30 days.

Propagation methods of White Palm

1. Ramet: the best ramet propagation is from May to June, the whole plant is pulled out of the basin, the rhizome is cut from the base of the plant, each clump has at least 4 leaves, and the plant is planted in half a shade to recover.

2. Sowing: seeds can be obtained by artificial pollination after flowering. Seeds should be sowed immediately after seed collection. The germination temperature is 30 ℃ and germinates 10-15 days after sowing. If the temperature is too low during germination, the seeds are easy to rot.

3. Tissue culture: young inflorescences and lateral buds were used as explants and inoculated on MS medium supplemented with 10 mg / L 6-benzylaminoadenine and 2 mg / 1 indole acetic acid after disinfection. Callus and adventitious buds grew after 40 days, and then the adventitious buds were transferred to MS medium with 2 mg / L indole acetic acid.

How to cultivate white palm by hydroponics?

1, container: White palm hydroponics is usually put at home, of course, you should choose a very good and beautiful container, how to choose depends on personal hobbies.

2. Temperature: the best growth temperature of white palm is 20-28 ℃, so you should pay attention to control the room temperature when you cultivate it indoors.

3. Illumination: the light of white palm hydroponics is mainly scattered light, not necessarily exposed to the sun, and direct sunlight should be avoided as far as possible in summer.

4. Change the water: change the water about 7 days in summer and 10-15 days in winter, and add a few drops of special nutrient solution for flowers.

5, fertilization: White palm hydroponics daily nursing should use clear water spraying foliar moisturizing, preferably spraying foliar fertilizer once a week.

Matters needing attention in hydroponic culture of white palm

1. White palm needs better light in winter and early spring, do not shade, and gradually shade when the light is getting stronger. If you enjoy it in the shade, you should not directly expose it to the sun, otherwise it will cause discomfort due to rapid changes in the environment, such as wilting, yellow leaves, and even death.

2. White palm needs higher growth humidity, and if the air is too dry, it can cause leaf wilting, which can be solved by strengthening water spraying or spraying water on the environmental ground, or covered with transparent plastic bags. however, when the light is good, it is necessary to have a little ventilation or open a breath on the top of the plastic bag, otherwise the temperature in the bag will rise sharply.

3. In order to prevent the occurrence of leaf dryness, white palm should spray foliar moisturizing with clear water during daily nursing, preferably spraying foliar fertilizer once a week, which can not only provide nutrition for leaves, increase foliar luster, but also achieve the purpose of resisting low temperature in winter. Using foliage plant nutrient solution, the leaves need to be sprayed with 0.3% potassium dihydrogen phosphate solution for 2 to 3 times at budding stage, which can promote its flowering.

4. If the white palm is harmful to mites, the leaves show bad symptoms such as wilting, gloss desalination, yellow blight and so on, which can be controlled by spraying special mites, such as triclofenac, Nisolan, pyridaben and so on. Common bacterial leaf spot, brown spot and anthracnose damage leaves can be sprayed with 50% carbendazim wettable powder 500 times.
