The root system is huge, the root system of the cactus is large, and the rooting is deeper. It can absorb sufficient water to maintain normal growth; the chip -shaped blades, the cactus blades are rejuvenating, which can effectively reduce the evaporation of water; waxy stems and leaves, cactus palms There is a layer of waxy stems and leaves in the stems that can effectively resist the exposure of ultraviolet rays; stalks are thick, and the cactus's palm stalks have strong shrinkability, and the epidermis can be protected without water supply.
1. The root system is huge
The root system of the cactus is very developed, which can not only go deep into the ground, but also spread to the surrounding To dozens of meters, so as to better get groundwater. In addition, the root system of the cactus is thicker, and the rooting is firm, which can absorb sufficient amount of water to maintain the normal growth of the plant.
2, needle -shaped blades
The blades of the cactus are needle -shaped because it adapts to the growth environment of long -term lack of water and degenerate. And the area of \u200b\u200bthe needle -shaped blades is small, which can effectively reduce the evaporation of water and help plants to lock more water.
3, waxy stems and leaves
and a layer of waxy substance on the stem of the cactus, which can make it a good root system well Resisting strong ultraviolet rays, so that it does not be sunburned, dehydrated death, can also reduce the evaporation of its own water, retain water very well, thereby adapting to the drought growth environment.
4. Struts of the stems
The stems of the cactus are thick, consisting of many thin -walled element cells, the stem meat is very soft, and it has very good meat. Good shrinkability, can freely retract its body to store water. Without water supply, it can rely on shrinking stem meat to protect the epidermis.
