How to cultivate Strelitzia

Strelitzia reginae is a perennial herb of Musaceae, native to Africa and Latin America. Its leaves are evergreen all the year round, with beautiful flowers, graceful flowers, and generous dignity. The colors are red and blue, bright and colorful. The flower shape resembles a crane. When a flower is in full bloom, it resembles a crane standing upright and guiding a neck. The key technologies for cultivation are summarized as follows: 1. Soil preparation Strelitzia reginae requires loose and humus-rich soil as nutrient soil, and appropriate amounts of phosphorus, potash, or cooked cakes are used as base fertilizers. Into a certain proportion of coarse sand in order to facilitate drainage and increase soil permeability. Soils suitable for growth and development of Strelitzia reginae are generally prepared by mixing 2 parts of vegetable garden soil, 1 part of rot leafy soil and 1 part of coarse sandy soil, or 4 parts of vegetable garden soil, 2 parts of peat soil, 3 parts of compost, and coarse sandy soil. Mix 1 part evenly. Second, adjust the water and fertilizer Strelitzia reginae afraid of drought taboo, watering should be with the season and plant growth and the actual degree of soil wet and dry. Summer growth and fall/winter flowering require sufficient water, and watering can be appropriately reduced after early spring flowering. In general, water is poured once a day in the summer, and the leaves and the surrounding ground are sprayed with clean water in the morning and evening to increase the air humidity. In rainy season, it is necessary to drain water in time; in the winter, watering should be appropriately reduced to keep the soil slightly dry; if it continues to grow, then Watering should be more appropriate and more diligent. Strelitzia reginae, in addition to potted soil with appropriate amount of phosphorus and potassium fertilizer as the base fertilizer, every two weeks or so in the growing season should be applied once thin fertilizer or "eight eighty", "Ouper" and other active humic acid liquid fertilizer In the fall and winter seasons, phosphorus and potash fertilizers are mainly used, and potassium dihydrogen phosphate is applied to the rhizosphere of water, so that the plants can grow vigorously and flowering. Third, sufficient light Strelitzia rejoicing plants, if the light is insufficient, easily lead to poor plant growth, less flowering or no flowering, so in the spring and autumn should be placed in sunny place culture; winter should receive more sunlight, otherwise it will be direct Affects the growth of leaves and the color of flowers. In summer, the sunlight is too strong. The plants must be placed under a shade shelter to prevent the leaves from being burned by the scorching sun and affecting the ornamental value. Fourth, suitable temperature Cold Strelitzia reginae is not tolerant to cold, the most suitable growth temperature is 15 ~ 25 °C, 8 °C below the stop growing. When the temperature in winter is not lower than 4°C, it can be placed in a place with light shining from north to south, and the number of waterings can be appropriately reduced to expose the ground to winter. When the temperature is below 4°C, flowers should be moved indoors or in a plastic greenhouse for wintering. 5. Pay attention to the change of the potted plants to the large potted ornamental flowers. It grows fast and has a well-developed root system. The general seedling period should be changed once a year. Once the plant is formed, it should be replaced every 2 to 3 years. In the spring ramets. When the ramets are selected, the mother plants of the sturdy tussocks are cut and cut from the rhizome with a sharp knife. 2 to 3 buds per plant are reserved. After the ramets, the ash or sulphur powder is applied at the incision and the shade is placed. After drying, colonize; if no ramets, deeper basins should be selected, and a layer of broken tiles should be placed on the pelvic floor for drainage and basal dressing.
