Alocasia esculenta, also known as Lotus, Guanyin taro and Euphorbia fischeriana, is a perennial evergreen herb of Araceae. The stem is stout, the skin is brown, and the leaves are as big as taro, which looks like elephant's ears, so it is also called elephant's ear taro. Alocasia alopecuroides is a shade-loving large-scale foliage plant, which is most suitable for garden cultivation in the south. In recent years, the author has put potted plants indoors for a long time and achieved gratifying ornamental effects. Keep it above 5℃ in winter. Every March and April, put the two or three-year-old seedlings in a 10 inch pot. The retting nutrient soil is mixed with 1/3 fine coal slag as the matrix (mainly loose basin soil). Then use decomposed animal hoof horns or pig and sheep manure as base fertilizer. After the plants germinate, topdressing the concentrated fertilizer solution containing nitrogen once a week. When the branches and leaves are luxuriant, reduce the application of nitrogen-containing solution and increase the application of phosphorus-containing solution (spraying potassium dihydrogen phosphate aqueous solution on the leaves is better), and the buds will bloom soon. Flower bud type, from light green to milky white, spike flowers about 20 cm long, emitting the fragrance of white orchids. The flowering period is 365438+ 10 month. When the climate is dry in May, water should be sprayed around the basin frequently. Be sure to wash the leaves. The flowerpot should be placed in a place with indoor air circulation, and the flowerpot should be rotated frequently to prevent the crown from tilting. When Miao was young, she changed the pots every March and April. When they grow to 4 cm, lift the roots, so that only the roots are buried in the pot soil, and the stem base is not allowed to grow into seedlings. If the seedlings are found to grow, they can be dug up when they are slightly longer and become new plants, otherwise they should be worshipped by hand immediately to avoid fattening with the mother plants. Always take the basin outdoors to receive scattered light, so as not to raise the stem and make the leaves too fat. Wild taro often bears seeds, which can be sown and propagated. The juice in the stem and leaf of Alocasia alopecuroides is poisonous and should not be eaten by mistake or in eyes.
