Information on cactus
Among many unique plants, cactus attracts countless plant lovers with its unique shape and tenacious vitality. This succulent plant native to the deserts of the Americas has evolved into a special survival mechanism over thousands of years and has now become a popular choice for indoor and outdoor greening. This article interprets its biological characteristics from a professional perspective, and attaches real shots of multiple growth stages. Analysis of cactus biological characteristics unique morphological structure Cactus family plants have a typical fleshy stem structure, with significant differences in height between 30cm and 3m. The waxy layer covered on its surface can effectively prevent moisture from evaporating. The needle-like thorns are actually degraded leaves. The yellow thorns are both a defensive weapon and a tool for condensing dew. The main root system is as deep as 2 meters underground, and the lateral roots can extend up to 5 times the plant height. Ecological adaptation mechanism Through the CAM photosynthesis system, such plants can absorb carbon dioxide at night, effectively reducing daytime water loss. The stem sponge tissue can store water equivalent to 90% of its own weight, and the characteristics of epidermal stomata that are closed during the day and open at night allow it to survive at high temperatures of 50℃. Environmental factors control the optimal growth temperature within the range of 18-35℃, and above 5℃ in winter. At least 6 hours of direct light are needed every day, but noon strong light should be avoided during the seedling period. It is recommended to use sandy loam with pH 7.0 -7.5, and 30% perlite can be added to improve drainage. Information on scientific conservation methods for cactus
Adopt the principle of "dry and irrigate thoroughly", water is watered every 15 days in spring and summer, and water can be stopped for 2 months during the winter hibernation period. Fertilization should be carried out with a low-nitrogen and high-potassium formula, and diluted liquid fertilizer should be applied every month during the growth period. Pay attention to protecting the main root when changing pots, and it is recommended to change the cultivation substrate every 2-3 years. Variety Appreciation Atlas
