Abstract
The Loess Plateau in the northern part of Shanxi Province has uneven rainfall and large evaporation, so droughts often occur. The drought has restricted the development of the local planting industry and the economy. Micro sprinkler irrigation has the advantages of strong adaptability, saving water, saving labor and land, increasing production, and preventing salinization, which is very suitable for this area. This micro-sprinkler irrigation design is carried out in typical plots, based on potato plant characteristics, rainfall data over the years, combined with corresponding specifications and actual conditions. This article uses a refraction micro-sprinkler with a spray diameter of 2.4 m. In the water transmission and distribution network, underground pipelines share 1,860 m of main pipes and sub-main pipes; surface pipelines share 1,200 m of branch pipes and 90,000 m of capillary pipes. The design meets the verification indicators of all irrigation groups, conforms to local actual conditions.
Highlights
With the progress of science and technology and the development of economy, water resources have become more and more important, and the concept of water saving has gradually integrated into our life
China is in short supply of water resources, with 2,300m3 per capita, accounting for only about a quarter of the world
The distribution of water resources is uneven in time and space, and there is a big difference in annual and inter-annual precipitation
Summary
With the progress of science and technology and the development of economy, water resources have become more and more important, and the concept of water saving has gradually integrated into our life. China is in short supply of water resources, with 2,300m3 per capita, accounting for only about a quarter of the world. The distribution of water resources is uneven in time and space, and there is a big difference in annual and inter-annual precipitation. Dry and water shortage is the fundamental reason that restricts agricultural development in most areas of China[1]
