What is a cactus plant?
The cactus, proudly standing in arid regions, has become a model of survival in the plant world with its unique shape and tenacious vitality. This succulent plant not only possesses an astonishing adaptability but also plays multiple roles in human life, from home decoration to agricultural production.
Analysis of Cactus Plant Characteristics
Morphological Features and Growth Habits
Cactaceae plants generally have flat, obovate stems that are densely covered with brown spines, which are actually degenerated leaves. Their thick, fleshy stems can store a large amount of water, and the waxy epidermis effectively reduces evaporation, allowing them to thrive in areas with annual precipitation of less than 200mm.
Superior Environmental Adaptation Mechanism
The unique CAM photosynthesis system of cacti enables them to open their stomata at night to absorb carbon dioxide and close them during the day for photosynthesis, a special metabolic way that can reduce water loss by 98%. Experimental data show that an adult cactus can store water equivalent to 90% of its body weight.
Various Reproduction Methods
In addition to seed propagation, cacti can quickly propagate through stem cutting. The cut stems can survive for several months in a dry environment and can sprout new roots within 2 weeks after contacting water, making them an ideal choice for horticultural cultivation.
Detailed Explanation of the Multi-functional Uses of Cacti
Indoor Ornament and Air Purification
NASA research has confirmed that cacti can absorb volatile organic compounds such as formaldehyde and benzene, and their ability to release oxygen at night makes them an optimal choice for bedroom plants. Maintaining an environmental temperature of 10-35℃ and changing the special sandy substrate every spring can ensure the healthy growth of the plants.
潜力 of New Food Ingredients
Mexico has cultivated edible cactus varieties, whose tender stems are rich in dietary fiber and calcium, with twice the vitamin C content of citrus fruits. After peeling, they can be eaten raw, stir-fried, or made into health beverages. The Food and Agriculture Organization of the United Nations has listed them as a potential food resource for the 21st century.
Ecological Protection and Security Barrier
Densely planted cactus hedges can form a natural protective barrier. Experiments have shown that a 1-meter-high cactus wall can effectively block 85% of intruders. Their root network can also stabilize the soil, preventing soil erosion and playing an important role in desertification control.
Core Rootstock for Horticultural Grafting
As the ideal rootstock for epiphytic plants such as蟹爪兰 and Epiphyllum, the survival rate of cactus grafting can reach 92%. Choosing a strong plant that has grown for more than 2 years and using the楔形嫁接法 with wound sealing treatment can achieve intensive cultivation of various ornamental plants.
From a desert warrior to a helper in life, cacti are constantly refreshing the boundaries of human knowledge. With the deepening of scientific research, new uses such as the development of medicinal ingredients and the conversion of biofuels continue to emerge. Mastering the correct maintenance methods, this magical plant will create more value for us.
