Cacti mostly grow in arid environments, and when the rainy season comes, their root system immediately becomes active, absorbing a lot of water, allowing the plant to grow quickly and flower and bear fruit quickly. During the dry season, it can go into a dormant state without eating or drinking, minimizing the consumption of nutrients and water in the body.
native to the east coast of Mexico, the southern and southeastern coastal areas of the United States, the West Indies, Bermuda, and northern South America; in the Canary Islands, India and eastern Australia;
Introduced in China at the end of the Ming Dynasty, it is commonly cultivated in the southern coastal areas and wild in the coastal areas of Guangdong, southern Guangxi and Hainan.

Cacti mostly grow in arid environments. Some are column-shaped, more than 10 meters high, weigh about 20,000 or 30,000 catties, stand majestically, very magnificent. Some of the thorny cactus, some of which have a lifespan of more than 500 years, can grow into giant balls with a diameter of two or three meters, and people split the upper part of it and dig up the tender and juicy stem flesh to quench their thirst and hunger.
Cacti also have a special ability to go dormant without eating or drinking during the dry season, minimizing the consumption of nutrients and water in the body. When the rainy season comes, they "wake up" very sensitively, and the root system immediately becomes active, absorbing a lot of water, so that the plants grow quickly and flower and bear fruit quickly. The root system of some cactus plants becomes carrot-shaped, which can store seventy or eighty catties of water.
Someone once wrapped a cactus in a dry paper bag and left it for more than two years, although it was slightly wrinkled, but one went to the pot, and after watering, it quickly grew new roots and regained its growth. The cactus is appreciated by humans for its wonderful structure, amazing drought tolerance and tenacious vitality.

The cactus in the desert has a very long root system, which can reach more than ten meters, so it can absorb deep underground water, and then the leaves of the cactus are thorny, and the cactus has a layer of leathery skin on the outside, which can greatly prevent the release of water.

Cut a cactus and you can taste the juice inside.
The thorns of the cactus are relatively hard, you can't pick them directly by hand, you need to pick them with a wooden stick or a knife, put the cactus on the fire and roast it until the surface turns yellow, you can eat it, although the taste is a little bitter, but for hungry people can fill their stomachs.
Cacti can not only eat in the desert but also quench thirst, this cactus contains a lot of water, as long as you gently cut a cactus, you can taste the juice inside, these cacti in the desert to save many people who lack water. In addition, the cactus can also be used as a water container, and the pulp inside can be pulled out to store water.

There is a huge cactus in the desert, and this cactus has a lot of water.
First of all, you should scrape a thornless spot on the cactus to prevent yourself from being injured.
Then, make a hole in the cactus so that you can drink it, and then the container will be followed or eaten directly by digging a piece.

Cut a slice with a knife and chew it! Remember to peel off the skin to add moisture. If you feel too bitter to chew, just squeeze its juice in a bowl.

No, you may not be able to eat (drink) cactus directly, and some cactus juice is poisonous, making you weak and dehydrated. You need to have a certain amount of knowledge.

Cacti are clumps of fleshy shrubs. Its water storage capacity is top-notch among plants, and as a result, we don't have to bother watering cacti every day. There are several characteristics that make it drought tolerant.
Cacti have thick leaf stems made up of storage cells that contain mucinous substances that prevent water loss. So these leaves and stems actually store a lot of water, not that the cactus itself doesn't need water.
Cacti, which survive in the desert all year round, also develop adaptive characteristics, their branches are empty inside and filled with moisture. Secondly, the leaves of many plants are very flat and spread, which increases the area where water evaporates.
-
The leaves of the cactus degenerate into thorns, which greatly reduces the area of the leaf skin and reduces transpiration, and the fleshy stems are able to store a lot of water, helping the plant to reduce water loss in hot and arid environments.
-
Cacti only have needles, which reduce water evaporation from the body. The stems are smooth and have a waxy layer that reflects sunlight effectively. The root system is well developed and can be fully absorbed. So it's good for people to survive in the desert.
-
Because the leaves of the cactus degenerate into thorns.

Hello dear, yes, but it contains a variety of toxins and fiber, which may cause problems such as food poisoning and diarrhea. The lack of water in the desert is a very dangerous situation, and it is very important to find clean drinking water. Moreover, cactus fleshy stems are not necessarily a safe, reliable, and effective source of water.
While cacti contain some water, they also contain a variety of toxins and fiber, which may cause problems such as food poisoning and diarrhea. If you're short of water in the desert, don't try to fill your stomach with a crickly claw first. Instead, follow certain steps and try to find a safe, reliable and effective source of drinking water.
1.Deserts have very little vegetation, but there may still be some water sources, such as creeks, wellheads, lakes, natural ditches and caves, and so on. If you're confident you'll be able to find these sources, go straight to get them.
2.If you can't find a source of water, it's important to find food. High-protein foods, such as rotating insects, reptiles, fish, and salted jerky, can keep the body as strong as skin and bones.
3.If water and food are still not found, then humanity's last hope is survival skills. You can try the leaky bag method, where a plastic bag is attached to a branch to form dew at night, and the bag is taken down in the morning to collect the dew.
When water is scarce in the desert, don't panic too much or try to blindly seek food. Concentration and following the right steps and methods is the only way to ensure a full and half survival rate.

Summary. Cacti are generally rehydrated in the desert by: Water storage:
The stems and leaves of cacti can store water. During the rainy season or when encountering water sources, cacti store excess water in the stems and leaves for emergencies. If water is not available for a long time, cacti use the water stored in the stems and leaves to sustain their life.
Water absorption: Cacti have a shallow root system that can absorb groundwater and rainwater through their roots, but this is not common in deserts. If some sporadic precipitation is encountered or in a place with a high water table, the cactus can absorb the water.
Reduced water loss: To reduce water loss, cacti usually retract their leaves or change the angle of their leaves during the day to reduce transpiration. At the same time, cacti also bloom at night, taking advantage of lower temperatures and higher humidity to absorb water.
In short, cacti in the desert are able to replenish water through their biological characteristics and adaptation to the environment to maintain their life activities.
What's going on. It's not a problem if the money is paid.
No, I've got it.

Kiss the laughing branch, the code word seems to need to be typed one by one to touch Jian Min, it's not good, it's not good, and you have to be satisfied. So I typed word by word, and told Zen to copy and paste quickly, and don't let you do this, otherwise you won't have to spend money. Thank you for your understanding. I wish you all the best and all your wishes come true!
"Cactus" is often seen, but have you ever eaten its fruit? How about the taste.
If you have heating, you can basically keep it.
If it is too dry, it is recommended that narcissus and hyacinth are recommended, both of which can be hydroponic, and they are just in time for the New Year. >>>More
