Border guards and soldiers are the loveliest people in peacetime. Their selfless dedication has created a safe living environment for us.
For those officers and men stationed in Tibet, there was no fresh vegetables to eat when the mountains were closed in winter due to heavy snow.
Nowadays, with the development of science and technology, officers and men stationed in Tibet can also eat green and fresh vegetables in cold winter through self-sufficiency.
This high-tech vegetable factory uses clean solar energy, combined with carbon dioxide exhaled by our bodies, to make vegetables fully grow on the plateau through photosynthesis and provide fresh green vegetables for the border guards.
Plateau has not been suitable for the growth of most vegetables since ancient times, only for the following reasons.
1. Bad climatic conditions With the elevation, the corresponding climatic environment is constantly changing. For the plateau, it is often because of the high altitude, so the temperature is low and the oxygen is thin.
The growth of green vegetables is inseparable from carbon dioxide and a certain temperature and humidity. These conditions are not available on the plateau, so it is difficult for delicate vegetables and even some trees to flourish on the plateau.
In addition, the plateau is windy and cold, so it is not suitable for planting fresh green vegetables in the wild environment. It is also for this reason that green vegetables have become precious on the plateau.
Second, the soil is barren and there is little precipitation. Due to the cross wind raging in the plateau and the scarcity of annual precipitation, the land planted in most areas of the plateau is very barren. In many cases, it is only suitable for planting cold-tolerant and drought-tolerant plants.
In the process of growing vegetables, in order to thrive, the corresponding nutrients and water are two essential conditions.
These two points are not available in high-altitude areas, so in the era when science and technology are not developed enough, the corresponding living conditions of officers and men stationed here have become very difficult.
By stationing officers and soldiers and eating green and fresh vegetables, I once again felt the power of science and technology. Without the development of science and technology, I think countless young soldiers will experience such difficult border defense conditions.
The development of science and technology has also improved the living conditions in the plateau, which I think is an excellent thing for people living in the plateau.
