What are the functions of cactus

Cactus, should be our most common plant, for cactus, we love and hate, love for him, because we affirm his spirit, do not like it, it is because it will hurt us when we are not paying attention, next let us know what is the role of cactus?

First, the function of cactus

The consumption of cactus

People often think that the cactus is just fried lilies as an ornamental plant, which is of no use. In fact, the fruits of many cactus plants can not only be eaten raw, but also be made into wine or dried fruit. In the Mexican market, the tender stems of some flaky cacti can be sold as vegetables. The wooden torso of some columnar cactus has always been used by Indians as building materials. The cactus flaky stem node can not only be used as livestock feed, but also its viscous juice can be used as a purifier for clean water quality. In some places, some cactus with thick thorns are planted on the edge of the house, which is used as a thorn hedge.

Medicinal use of cactus

In every 100 grams of edible cactus, about 220 micrograms of vitamin A, 16 milligrams of vitamin C, 1.6 grams of protein, 2.7 milligrams of iron, can produce 25 kcal-30 kcal calories. In recent years, many countries have begun to use cactus to treat arteriosclerosis, diabetes and obesity, and achieved good results. It is said that this is mainly because the vitamins contained in cactus can inhibit the absorption of fat and cholesterol and slow down the intake of glucose. The nutrition of edible cactus is very rich, it contains a lot of vitamins and minerals, and has the effect of reducing blood sugar, blood lipid and blood pressure. the tender stem of edible cactus can be eaten as a vegetable, and the fruit is a kind of sweet fruit. The old stem can also be processed into health products and medicines with the functions of removing blood lipids and lowering cholesterol. Mexican cakes, snacks and dishes are very popular, which are cooked from the flowers of the local cactus family.

2. Culture of cactus

Air, water and soil are indispensable. How to master and appropriately adjust its best growth conditions in order to make cactus flowers grow well is even more important. Now let's understand and master the basic techniques of cactus cultivation.

Light most cacti like to grow in the sun, although the growth rate of cactus in the hot sun is slow, but the plant is relatively strong, and strong sunlight can promote the plant to blossom and bear fruit easily. Strong thorn genus, golden amber genus, grow in abundant sunlight, the thorn will also grow stout, thorn color is more bright.

Water content

Most of the cactus flowers are native to the hot and arid desert wilderness of South and North America, which makes them drought-resistant and high-temperature resistant. Some large plants will not die even if they are not watered for a year or two. For example, a tree with a diameter of 42 cm in diameter cultivated by the author in 1991 was gnawed out of a hole near the bottom of the sphere with a width of 13 cm and a depth of 7 m due to rodent damage. The wound began to erode due to infection, and the only rescue method was to remove the rotten part from 4 places above the bottom accounting for about 1 cm of the height of the sphere. After disinfection and drying, it was replanted on plain sand to induce roots for nearly a year. The diameter of the ball shrunk by 2m / m. After the new root was germinated, it was transplanted to the culture soil to cultivate two friends, and the diameter of the ball returned to its original size. The above example is enough to illustrate how extraordinary the cactus can withstand drought. But being able to endure drought does not mean that the cactus likes the dry environment and neglects reasonable watering. In order to make the cultivated cactus flowers grow well and give full play to the ornamental characteristics of different varieties, reasonable watering is absolutely necessary.

Temperature degree

The growth and development of all green plants need certain temperature conditions. Plants growing in different species and regions also have different needs for temperature. Cactus flowers are originally born in the environment with large temperature difference between day and night, so most of them have strong adaptability, as long as several kinds of cactus with different suitable temperature can be cultivated together under a certain stable growth temperature. However, this strong-free cultivation method will affect the growth and development of some plants because they can not get the suitable growth temperature for a long time. The optimum temperature for the growth of most cactus is 20 Mel 35 ℃. However, most species prefer large temperature difference between day and night, which is beneficial to the production and accumulation of organic matter under the condition of 35 ℃ in the day and 15 ℃ at night, thus promoting the exuberant growth of the plant.

The above for the role of cactus, we have done to understand, I believe you have a better understanding of this common ordinary plant, for the role of cactus, have a clear understanding.
