Ecology and Application of Underground Stem Plants
Underground stem plants refer to stems that grow in the soil and are connected to the root system. They can survive in arid or cold environments and have various ecological and application values. This article will introduce the characteristics, classification, distribution, ecological functions, and applications of underground stem plants, allowing readers to gain a deeper understanding of these amazing plants.
Characteristics of Underground Stem Plants
Underground stem plants are a type of plant with a special morphology, whose main feature is that the stem grows in the soil and is connected to the root system. They can store nutrients and water through their underground stems, have a long growth cycle, and possess a certain degree of stress resistance.
Classification of Underground Stem Plants
Underground stem plants can be divided into five categories based on the type and morphology of their underground stems: sclerotia, rhizomes, tubers, corms, and bulbs. Each category has its own special morphology and ecological functions.
Distribution of Underground Stem Plants
Underground stem plants are widely distributed around the world, but the distribution areas of different types vary. For example, sclerotia are more common in tropical rainforests, while rhizomes are more common in the Arctic regions.
Ecological Functions of Underground Stem Plants
Underground stem plants have various ecological functions, such as drought resistance, cold resistance, wind erosion prevention, soil and water conservation, and they play an important role in the ecosystem.
Application of Underground Stem Plants
Underground stem plants not only have ecological value but also high economic and medical application value. For example, ginseng, Dendrobium, and Polygonatum are all underground stem plants with medicinal value.
Sclerotia Plants
The characteristic of sclerotia plants is a spherical structure that grows in the soil, with branched hyphae inside. Sclerotia plants are an important type of underground stem plant in tropical rainforests and have excellent medicinal value.
Rhizome Plants
Rhizome plants form a structure where roots and stems coexist in the soil, and they have good stress resistance and survival capabilities. For example, aloe and galangal are rhizome plants.
Tuber Plants
A tuber plant is an underground stem similar to a corm, with an irregular spherical or oval shape, such as potatoes and taro.
Corm Plants
A corm plant is a spherical structure composed of thick leaves and stems, such as onions and chives.
Bulb Plants
A bulb plant is a structure composed of thick scale leaves, such as daffodils and tulips.
Application Value of Underground Stem Plants
Underground stem plants have various application values; they can be used as food, medicinal materials, and industrial raw materials. For example, Atractylodes, Coptis, and Astragalus are common medicinal materials from underground stem plants.
Conservation of Underground Stem Plants
Underground stem plants play an important role in the ecosystem, but with the increasing human activities, their living environment is threatened. Strengthening the conservation of underground stem plants is of great significance.
Reproduction of Underground Stem Plants
Underground stem plants have diverse reproduction methods, which can be carried out through the expansion of underground stems, budding, vegetative propagation, etc. These methods all have a certain degree of adaptability and survival ability.
Cultivation Techniques for Underground Stem Plants
The cultivation techniques for underground stem plants vary depending on their type and distribution area. But in general, they all require good drainage and ventilation conditions, as well as appropriate nutrient and water supply.
Underground stem plants are a type of plant with special morphology and ecological value. They can survive in harsh environments and also have a wide range of application values. Strengthening the research and protection of underground stem plants helps to promote sustainable development.
