What is the function of the spines of the cactus 10

One is to protect yourself, and the other is to reduce the evaporation of water.

Cactus generally lives in arid deserts, in order to reduce water evaporation, it transforms its leaves into sharp thorns, from a distance, the cactus looks like a hedgehog curled up in the shape of a ball, and like a cradle woven with thorns, in which lies a sleeping baby, very cute. When I walked in, the surface of the cactus ball was not so smooth and flat, but showed uneven grooves. The thorns, on the other hand, are arranged in a very regular manner on the cactus, and each bunch has about eleven or twelve thorns.

Used to protect themselves and moisture evaporation.

Why does a cactus have thorns, and what do its thorns do?

Cacti are poisonous.

The thorns of the cactus are poisonous, if you accidentally prick it, it may cause an allergic reaction, such as a large area of redness and swelling, etc., once this is done, you can immediately apply soapy water to the affected area and then clean it, clamp it out with tweezers, and then bandage it.

Cactus cultivation method

1. Temperature. Cactus growth is suitable for temperatures of 16-22 degrees Celsius, summer temperatures up to 35 degrees Celsius It is also acceptable, above 35 degrees Celsius will cause sunburn. In winter, the temperature should not be lower than 5 degrees Celsius, so pay attention to cold protection and warmth.

2. Illumination. Cactus growth requires sufficient light conditions, and the growth of cacti must be guaranteed for light time throughout the year. During the growing season, 8 hours of light are used every day, and in the summer, the sun is strong and shade is required. In winter, it is placed outdoors at noon for light exposure.

3. Watering. Cactus is a drought-tolerant plant, and it is used during the growing period to water when it is dry. The soil is slightly dry and watered in time, and the soil is moist and does not need to be watered.

Summer and winter are the hidden periods when they enter the semi-dormant period and the dormant period, at this time, according to the growth of the plant, the watering should be appropriately reduced or stopped.

4. Fertilization. During the cactus growth period, use decomposing fertilizer or diluted nitrogen, phosphorus and potassium compound fertilizer once a month. Before entering the dormant period in winter, it is necessary to use phosphate fertilizer once, and stop fertilizing in winter.

The spines of the cactus are generally not poisonous and usually do not cause poisoning after contact or being stabbed, but the spines of the cactus contain some alkaloids, and the swelling of the contact site may be related to allergic reactions, inflammatory reactions and other factors.

1. Allergic reactions: cactus contains a certain amount of alkaloids and other ingredients, and people who are allergic to cactus components or belong to allergic constitution may cause allergic reactions after contact with cactus stabbing or being stabbed, resulting in local swelling, accompanied by allergic reactions such as pain, itching, redness and swelling;

2. Inflammatory reaction: After contact with the cactus prick or being stabbed, there will be local damage, and the injury will induce inflammatory reaction, which will then cause local swelling, but the degree of swelling is generally mild. If the wound is not cleaned properly, secondary bacterial infection may also cause local swelling, accompanied by inflammatory symptoms such as redness, swelling, heat, pain, and suppuration.

In addition, if the cactus spine is broken and the foreign body remains at the site of the puncture, suppuration may also occur, resulting in local swelling. At this time, it is generally necessary to remove the severed puncture as soon as possible, and actively carry out anti-infection**, and you can apply erythromycin ointment, chlortetracycline hydrochloride ointment and other drugs according to the doctor's instructions to promote the resolution of symptoms. If the swelling is severe, surgical incision and drainage should also be considered to facilitate **.

<> cactus is a very common plant in daily life, I believe everyone knows that there are thorns on the cactus, so what is the function of the thorns of the cactus? The spines of the cactus are used to protect themselves from evaporating more water and to reproduce better. Since cacti live in desert areas, there are thorns on the leaves that can better resist drought, and making the leaves into needles can reduce water evaporation.

In addition, the sun is too intense, and its thorns can also be used to properly block out some chaotic light. In addition, the sand on the ground will become very hot after being exposed to the sun, and the thorns on the cactus at this time can also be used to resist the heat, which is more conducive to the growth of cacti in the harsh environment.
