What is the difference between orchids and orchids
Among plant lovers, confusion between orchids and orchids is common. These two plants with similar names but completely different names have significant differences in plant classification, morphological characteristics, growth habits, etc. This article will systematically analyze the differences between the two from a botanical perspective, and attach detailed conservation suggestions. 1. Differences in botany classification 1.1 Orchid grasses of different families and genera (Commelina communis) belong to the genus Commelina of the family Commelina and are typical monocotyledons herbs. Orchids belong to the genus Orchidaceae, which is the most evolved group among perennial herbs. 2. Comparison of morphological characteristics 2.1 Color and flower type Orchids are famous for their iconic blue flowers. 3-4 flowers are clustered in an umbrella shape, with only 2 petals. Orchids have a variety of colors such as white, yellow, pink, and purple (no blue varieties). The typical structure is 3 sepals +3 petals, of which the specialized lip has a pollination function. 2.2 Leaf characteristics Orchid leaves are lanceolate, and bracts unfold into hearts. Orchid leaves are leathery strips, up to 50cm long, and veins are distributed in parallel. 3. Ecological distribution characteristics 3.1 Differences in geographical distribution Orchids are concentrated in areas south of the Yangtze River, especially common in the southwest mountains. Orchids are widely distributed in our country, with endemic varieties in Yunnan, Sichuan and (T-W) accounting for 67%. 3.2 Micro-environment requirements Most orchids grow in streamside wetlands and prefer direct light. Orchids are mostly attached to tree trunks or rock walls and need to scatter light. 4. Cultivation and management points 4.1 Water management Orchids need to keep the substrate moist (water content>60%), and orchids should maintain a "moist but not wet" state (water content 40-50%). 4.2 Fertilizer ratio Apply nitrogen fertilizer (N-P-K=3-1-1) 1-2 times a month to orchid grass. It is recommended to use special slow-release fertilizer (N-P-K=1-2-2) for orchids, and apply it once every quarter. 4.3 Temperature-controlled orchids have a suitable temperature of 15-28℃ and need to overwinter>5℃. The suitable temperature for orchid growth is 18-25℃, and most varieties need to overwinter at 10℃.
Through systematic comparison, it can be seen that there are essential differences between orchids and orchids in terms of genetic pedigree, morphological structure, and ecological needs. Mastering these identification points can not only avoid erroneous purchase and wrong cultivation, but also improve the success rate of cultivation in a targeted manner. It is recommended that enthusiasts combine the observation of plant specimens to deepen their understanding in practice.
