Matters needing attention in cactus culture for radiation protection

Cactus is a kind of plant that people are very familiar with, can be seen in the flower market, is a common plant. But do you know that cactus is protected from radiation? Let's find out together.

We live in a world full of radiation, in fact, radiation is not as terrible as we think. As long as the temperature is higher than absolute zero (minus 273.15 degrees Celsius), different objects will radiate their own energy through waves. Whether it can cause serious harm to us depends on whether it can destroy the stability of the atomic structure of the human body. Fortunately, it is very difficult for us to come into contact with ionizing radiation that can cause cancer and teratogenicity by mutating our genes, and we are often exposed to non-ionizing radiation that does not destroy the structural stability of the human body. the effects it can have on us include thermal effects and induced currents. Computer radiation belongs to electrical radiation and belongs to the thermal effect of non-ionizing radiation, but the thermal effect it can release is not enough to cause harm to the human body, so we do not need to worry about computer radiation.

Since we don't have to worry about computer radiation, can the cactus really protect against radiation? The reason why cactus is considered to be a master of radiation protection is that it resists the thermal effect of the sun in the desert, but whether it is stronger than other plants has not been proved, and being able to resist the thermal effect of the sun does not mean that it can absorb the thermal effect of non-ionizing radiation. Cactus anti-radiation has no scientific basis. The only thing that is certain is that if the cactus can block the sun for people like a towering tree, it can also resist the thermal effect of the sun, but only by placing the cactus next to the computer. it is impossible to make the non-ionizing radiation heat effect released by the computer turn and be absorbed by the cactus, because the non-ionizing radiation exists in the form of electromagnetic waves, it is linear radiation, and can not turn. Therefore, the rumor of cactus radiation protection is destroyed, but put a pot of green plants (cactus can also be), through plant photosynthesis can purify the air, staring at computer visual fatigue to see green plants can also improve visual fatigue, is also a good choice.

The function of cactus

1. "oxygen bar" cactus at night

Cactus usually begins to breathe when it is cool at night. it opens the stomata on the leaves, absorbs carbon dioxide, and then exhales oxygen, which is like adding an air freshener to the room, which can purify the indoor air. so it's an ideal flower for the room.

2. A master of dust absorption

Small cactus plants, although inconspicuous, but vacuuming is also quite powerful, put a cactus indoors, can play a role in purifying the environment, generally hydroponic cactus environmental protection clean, the effect will be better.

3. There are many benefits of eating cactus

There are many cacti, the edible cactus is very rich in nutrition, contains a large number of vitamins and minerals, has the effect of reducing blood sugar, blood lipid and blood pressure, and the tender stem of edible cactus can be eaten as a vegetable. The fruit is a kind of sweet fruit, and the old stem can also be processed into health products and medicines with the functions of removing blood lipids and lowering cholesterol.

Matters needing attention in cactus culture

1, spring, autumn and winter these three seasons, the sun is not strong, the temperature is not high, cactus leaf water evaporation is less, so watering can not be too much. Just the right amount, the temperature will rise in summer, watering will increase a little bit, but not too often, spray some water to the cactus, always keep the place where the cactus is put, the air is moist and not dry. You can spray a small amount of water with a spray can at any time.

2. Cactus likes to live in soil with adequate nutrition and loose air, and it is usually best to cultivate the soil specially. Vermiculite: fine sand: humus = 2:2:1, and then stir evenly. The culture soil should be barely clumped by hand, and loose sand is better. This kind of soil is more suitable for cactus growth.

3. In terms of watering, no matter what season it is watered, it should be thoroughly watered. "if you don't dry, you will not water thoroughly." that is, you don't have to water frequently, but once watering will make every part of the soil drenched, and you can't water it only to the middle waist. It will rot easily.

4. Spring, summer and autumn is the cactus growing season. In winter, plants will enter a dormant state and stop growing. At this stage, watering should not be too much, so that the potted soil can be moist. Plants absorb less water in winter, and too much watering is easy to rot their roots. Cactus is more like the light, take it out to bask in. Can not be in a hidden place for a long time, but it is not suitable for long-term exposure. The sun shines best in the morning.

5. The newly planted cactus should not be watered first, it can be sprayed several times a day, a small amount can be watered half a month later, and the new roots can be watered normally after a month.

6. Apply mature thin liquid fertilizer every 10 days to half a month, and do not apply fertilizer in winter.
