The difference between yellow fruit orchid and white orchid
In the street trees in southern cities, yellow fruit orchids and white orchids often cause confusion among plant lovers. These two trees with similar names not only have similar flower types and aromas, but also hide a special connection in plant taxonomy. By systematically observing their botanical characteristics and growth performance, we can more accurately grasp their similarities and differences. Plant identity confirmation, scientific name unity verification, plant classification data show that yellow fruit orchid and white orchid are actually synonyms of the same species of Magnoliaceae, and their scientific name is Michelia×alba. This variety is formed by natural hybridization and has the excellent characteristics of male parent and female parent. It is widely cultivated in the Yangtze River Basin and south of the country. Ecological characteristics express light and temperature requirements. As a typical subtropical tree, its suitable growth temperature is 15-28℃. Continuous high temperatures above 35 ° C in summer will cause the leaves to curl, and cold prevention measures should be taken when temperatures below 5 ° C in winter. Direct light should be guaranteed for more than 6 hours every day. Insufficient light will affect flower bud differentiation. The key points of water and fertilizer management adopt the irrigation principle of "seeing dry, seeing wet" to keep soil moisture within the range of 40-60%. Applying balanced fertilizers of nitrogen, phosphorus and potassium during spring germination and topdressing of phosphorus and potassium fertilizer before flowering can improve flowering quality. During the rainy season, attention should be paid to drainage and waterlogging prevention. Accumulating water for more than 48 hours will cause root rot. Identification of related varieties and morphological differences in yellow orchid Michelia champaca, as an independent species, has orange-yellow tepals and thicker leathery leaves. The flowering period of the two overlaps, but the flowering period of yellow orchids is later, usually concentrated from June to October, and the flowers have a clear sweet and greasy feeling. By comparing the trunk characteristics and observing the bark, subtle differences can be found: the skin of yellow fruit orchid is light grayish brown with shallow cracks, while the bark of yellow orchid is dark gray with vertical deep grooves. In terms of branch growth form, the branch angle of yellow fruit orchid is larger, forming a more open umbrella-shaped crown.
Through systematic comparison, it can be found that the unity of yellow fruit orchid and white orchid in the plant classification system is significantly different from its related species yellow orchid. Correct identification requires integrating multi-dimensional characteristics such as flowering period, color, and tree shape, which has important guiding value for garden planning and family planting.
