How many nutrients are needed to support a healthy body? I haven’t seen the authoritative figures yet. Whether the longevity of the elderly is related to diet and living environment, and no expert has ever said such an absolute conclusion. For example, how many kinds of grains, how many kinds of vegetables, how many kinds of muscles and fat of terrestrial and aquatic animals, and the growth environment and nutrients of these materials. The source of drinking water and what kind of plants and minerals participated in the drinking water to people’s dining table. There are also air components that enter the left and right physiological functions of the lungs through breathing every day, as well as floating objects in the air, such as fragrance, floral fragrance, dust, metal particles, it is now a relatively fashionable noun PM2.5. However, what we are talking about now is PM2.5, which refers to harmful floaters. The media have reported to a few longevity elders and longevity villages, but there is no final conclusion on how to live longer. From the perspective of environment, it is said that longevity people live in green mountains and waters, and it is natural that there are hundreds of herbs to protect them. Starting from eating habits, it advocates that longevity people insist on coarse tea and light rice for a long time, and interprets the way of longevity with nutrition that does not destroy the original taste of plants. From the perspective of mood and practice, it is said that peace is far away, the world is troublesome, living in the deep mountains and eating clean things, naturally it will not be damaged by gas and life will be short. There are also some ways to explain longevity from the perspective of genetic genes. Most people disagree, because the overall reason for the longevity of Chinese in the 21st century is not caused by genetic inheritance. Nowadays, no matter in rural areas or cities, life is much better than before the reform and opening up. Just like what Zhao Benshan said in his sketch, everyone is willing to enjoy such a good day, therefore, physical health is particularly important, especially for people over 50 years old, the obstacles of life are almost gone, and the rest of the days to enjoy happiness are left, how to live a good health has become the main pursuit in life. But most people can’t get what they want. First of all, it’s hard to understand the food and drink. For example, the social development is heading for urbanization. Who knows whether the residents in the city have pesticide residues or not, and they grew up in the ecological environment, I grew up in a man-made environment, such as the content of organic matter in the soil without chemical fertilizer or herbicide. And whether the drinking water is polluted or not, and whether there are beneficial ingredients which are dipped from plants and minerals. What are the components that should or shouldn’t be in the air? Are they repairing and strengthening our bodies or slowly encroaching on physiological functions that we shouldn’t lose. If you are lucky enough to visit the biologically rich mountain area, it is not difficult to see the rationality and fairness of natural ecology to life. On a hillside where loess can hardly be seen, all kinds of vegetation have their own lives, although they are not necessarily extremely happy, they can be seen from the natural cycle of spring, prosperity and autumn withered. Their visible footprints are the increasingly black loess, while the invisible footprints are the good ecological environment that comes back and forth, and the colorful Earth creatures generation after generation. Human physiological experts say that the ecological load is too heavy, the ecological cycle has undergone vicious changes, and the living environment is no longer what it used to be. How many species that repair the environment have quietly withdrawn from the stage that makes them linger on because of their discomfort, it is estimated by human beings that there are species leaving with hatred every day. However, no one can stop them now, because there is no end to greed, not only human beings, but also any species on the Earth, I have never given up all my efforts to expand my population. Human beings are the smartest species on the Earth, proposing and propagandizing the benefits of biodiversity to any species on the Earth, but no matter which species is trying their best to reproduce, and try our best to kill other species to make their lives more comfortable, so the result of competition may make the environment adapt to the existing species less and less, because the conclusion of human observation research is: in the ecological environment of the Earth, species disappear every day. Who on earth will be the ultimate witness of environmental deterioration depends on whether the change speed of species adaptation genes can keep up with the speed of environmental deterioration. Such law of ecological development is baimiyishu destined to extremes meet tragedy. Changing and delaying the time of tragedy is to try to keep the existing species. Economic Forest orchard management, soil organic matter content is the guarantee of fruit tree resistance, fruit quality and healthy body of fruit eater. How to improve soil organic matter content does not necessarily require applying organic fertilizer, growing grass in the Orchard should be a way. The more varieties the grass has, the more organic nutrients there will be. As long as you control it, don’t let the grass affect the growth of fruit trees. People often say that the sky will not destroy the grass. It is natural that the sky does not destroy the grass. How can we compare? Since we can’t be destroyed, why can’t we save some costs to make use of it. For our life, any species will have disadvantages to us and advantages that we can take advantage.
