[Going into the countryside to see a well-off society] Shaanxi's Yulin sandy land turns into fertile land. The development of the tertiary industry brings more job opportunities to the people

  CCTV News: In Yulin, Shaanxi Province, with the help of modern agricultural technology, tens of thousands of acres of sand have been turned into fertile land.

Chahezi Township, Yuyang District, Yulin City, Shaanxi Province, is located in the hinterland of the Mu Us Sandy Land. It is overlooked from the air. After years of continuous local efforts, the Mu Us Sandy Land has been controlled.

Now, the surface of the sandy land is covered with various vegetation and crops.

Among them, in the darker green areas, most of them show circular regular patterns, which are arranged on the ground in an orderly manner.

You may be more curious, why is there a circular or semi-circular pattern?

In fact, this should start from the planting method.

  This place was originally a desert. Through the transportation of loess, it has changed from a bare little grass to the current full of vitality.

The reason why such a circular pattern is formed is inseparable from its sprinkler irrigation system.

The center of these large round farmland is the water source of their reservoir. The sprinkler irrigation system takes the water source as the center point and rotates and irrigates like the hands of a clock, thus forming a circular regular pattern.

The coverage of loess and the automatic sprinkler irrigation system have realized water saving to a certain extent.

In addition to these automatic sprinkler irrigation systems that can take care of the circular area, where the circular area cannot be taken care of, there are water pipes under each ridge of potatoes, and there are water holes on the water pipes. This sprinkler irrigation system saves water to the greatest extent.

  Nowadays, potatoes, alfalfa, and corn are mostly planted on round desert farmland. The average annual income per mu of the three crops ranges from about 1,000 to 3,000 yuan.

The three crops are cultivated in rotation. The planting period of alfalfa is five years, and four crops can be harvested each year. After each harvest, the root system of alfalfa will stay in the sand to maximize the effect of wind prevention and sand fixation.

At present, these three crops have all been mechanized, especially taking alfalfa as an example. From harvesting to packing into square or round haystacks, and then running to warehouses for storage, the whole process has been mechanized.

The blessing of mechanization has brought about an increase in scale and even the development of downstream industries.

The alfalfa, corn and other feed industries downstream of the breeding industry, beef cattle and lake sheep, are already quite large in the local area.

  Take Yuyang District of Yulin City as an example, the scale of Hu sheep has reached 100,000.

With an advantageous scale, the local area is currently considering the construction of a slaughter and processing plant, and even an in-depth processing plant for beef and mutton. The development of the tertiary industry will bring more employment opportunities to the surrounding people.
