Starting from the northwest of Su Province, Qi Zheng chose to go south along the Hexi Corridor.

The Hexi Corridor, located in the west of the Yellow River, is sandwiched between the Qilian Mountains and the Alxa Plateau, and is connected to the Great Desert in the west, with a length of about 1,000 kilometers from east to west and a width ranging from 10 to 100 kilometers from north to south.

The geographical location of the Hexi Corridor is extremely important, and it is not an exaggeration to call it the Strait of Malacca on land in East Asia.

The section of the Hexi Corridor can be described as the dazzling Maijishan Grottoes, the Yellow River Customs Line, the Hanleitai Tomb, the Danshan Military Horse Farm, the Atomic City, the Tianxia Xiongguan, the Dunhuang Mogao Grottoes and the Crescent Moon Mingsha......

In the past, when we mentioned the Hexi Corridor, the Western Regions or Saibei, we thought of the desolation and cruelty of "drunk and lying on the battlefield Jun Mo smiled, and a few people returned to fight in ancient times", "The north wind swept the ground and the grass folded, and the snow flew in August".

But Qi Zheng went all the way south, but he felt a different kind of northwest.

If you don't look at the snow-capped mountains in the sky and the surrounding deserts, the oases you pass by will be thought to be a large area of rich countryside in the south of the Yangtze River.

Iron Horse, Autumn Wind, Saibei;

Apricot blossoms, spring rain, Jiangnan.

These two contrasting scenes are harmoniously united in the Hexi Corridor.

With the wisdom of the Chinese, as long as there is water and fine soil, it will become an oasis, and the desert can also become a prosperous heavenly mansion.

It is different from the Sahara Desert and the Australian Desert.

Although the climate of the Hexi Corridor is arid, the Gobi and deserts are widely distributed, and the annual precipitation in many places is less than 200 mm.

But fortunately, thanks to the existence of Qilian Mountain, it nourishes and nourishes the entire Hexi Corridor.

The Qilian Mountains are about 1,000 kilometers long from east to west, with an annual runoff of about 15.8 billion cubic meters, and nearly 1,000 large and small rivers are spitted, forming a rich oasis and a large grassland in front of the mountain. Look at 1 gross 2 lines 3 Chinese net

Oases are scattered like small islands in the vast desert Gobi, which has become an important support for agriculture and urban development.

It is precisely because of the continuous supply of water and soil from the snow-capped mountains that a lively and prosperous place will appear in the desolation of Mars.

......

On the way, Qi Zheng often had a feeling that it was the love of the creator that gave the Chinese nation a place to live.

If it is said that the people of the southeast coast should be grateful to the people outside the northwest, because they bear the drought and desolation that should be borne by the people of Jiangnan and Liangguang, it will certainly be regarded by many as nonsense.

But it's true.

If you look at a map of the world's landscape distribution, between 23 and 35 degrees latitude, around the earth, whether it is the eastern hemisphere or the western hemisphere, and whether it is the northern hemisphere or the southern hemisphere, most of them are deserts.

But China is an exception.

When the desert arrived in China, it stopped, not only did it stop, but it also made a 180-degree change, from a hot and arid desert to a drizzly and silky Jiangnan.

It's all up to the Tibetan Plateau.

To put it simply, the Tibetan Plateau, which rises around 25 to 35 degrees north latitude, changes the state of atmospheric circulation. The hot and dry air of the subtropical high was blocked by the plateau and carried to the northwest and outside the Saiwai area, forming a desert in those places, and the eastern part of China, which should have been affected by the hot and dry westerly winds, escaped the fate of becoming a desert.

If there is no rise of the Qinghai-Tibet Plateau, according to the perspective of solar radiation and the distribution of heat, China will be such a tropical humid zone, a subtropical high-pressure dry zone, and a temperate humid zone from south to north. In other words, the current eastern humid zone may be an arid desert area, while the current northwest arid zone may be a warm and humid area.

Therefore, without the high cold of Qinghai-Tibet, without the drought and desolation of the northwest, there would be no humidity and richness in the south of the Yangtze River.

This is nature's chain of cause and effect.

Therefore, feeling the colorful cultural landscape of the Hexi Corridor, the desert is like the sea, the oasis is like an island, and Qi Zheng is with a mentality of admiring miracles.

......

In addition to the forces within the earth, in the Hexi Corridor, the wind is the carver of the earth, and the glacier is the shaper of the mountains.

Mountains are an important part of the Hexi Corridor.

Most of China's oases are formed in the mountains of arid regions. Without the presence of these mountains, there would be no water and fine soils, and it would be difficult to develop oases.

On the other hand, mountainous areas are often rich in mineral resources.

In Suzhou Province, the output of nickel, cobalt, platinum, iridium, rhodium, selenium and other mines ranks first in the country, and the resource reserves of gold, ruthenium, zinc, tungsten and other metal deposits also rank among the top five in the country.

Although there are not many green waters and green mountains, the mountains in the Hexi Corridor seem to be full of "gold and silver mountains".

But while mountains shape landscapes, nurture culture, and bestow wealth, they also show the cruelty of nature with their harsh side.

Mountains are still a barrier to human civilization that communicates and integrates. The inconvenience of transportation has greatly limited the development of the Hexi Corridor since ancient times.

Even today, poverty in the Hexi Corridor is still prominent. The annual per capita GDP and annual per capita income of residents in Suzhou Province both rank first in the country. The combined GD of all cities in the Hexi Corridor is less than the GD of one city in Jiangnan Province.

On the other hand, ecological issues cannot be ignored. Since the Ming and Qing dynasties, the increase in population, the over-cultivation of agriculture and animal husbandry, the destruction of the Qilian Mountains, and the over-exploitation of groundwater have seriously deteriorated the ecological environment of the Hexi Corridor.

The relative richness that Qi Zheng saw also paid a great price.

However, adapting to nature, using nature, and transforming nature are not the themes that human development has been exploring for millions of years.

Bringing poverty out of the mountains and letting development into every inch of the country is the direction of efforts that Su Province and even all localities are sparing no effort to.

Qi Zheng's trip also came with this hope and ambition.

......

As an area with a long history of agricultural development, the Hexi Corridor has great agricultural potential.

The Hexi Corridor is rich in light and heat resources, has high water resource utilization efficiency, and has a large land area, which has unique conditions for the development of characteristic agriculture.

The Hexi Corridor is famous throughout the country for its "three golden flowers", namely seed breeding, plateau summer vegetables, and grape wine.

Comparatively speaking, malting barley is only a lightweight industry.

But for farmers in suitable areas, it is both a traditional industry and a core industry.

For Qi Zheng and Jia Gu, malting barley was not the whole focus of the trip.

Due to the low precipitation, large evaporation and dry air, the purity, moisture content, germination rate and clarity of the seeds produced have reached the national standard. The Hexi Corridor is also known as the "natural drying ground for seeds".

Give me a seed and I can change the whole world.

With the development of science and technology and the establishment of modern agricultural system, seeds have become the focus of international agricultural development and competition, so the Hexi Corridor has become the most competitive place for domestic and foreign seed production enterprises.

As Jiagu, who is interested in building the whole industrial chain, it is also an inevitable choice to "grab" the Hexi Corridor and establish its own seed production base.
