Description

Automatic water storage and sprinkling irrigation system for protecting river bank vegetation in arid region

Technical Field

The utility model relates to the technical field of ecological protection and sprinkling irrigation devices, in particular to an automatic water storage sprinkling irrigation system for protecting river bank vegetation in a arid region.

Background

Due to the strong evaporation in the arid regions, salts accumulate in large amounts in the surface soil. The accumulated salt enters the groundwater system through natural and unnatural processes such as shallow groundwater level fluctuation, rainfall, agricultural irrigation and the like, so that underground brackish water or salt water is widely distributed in the underground shallow aquifer of the arid region. The invasion of saline water under the river bank zone can cause salt accumulation in the river bank zone, and the originally fragile river bank zone ecosystem of the drought region is destroyed. In recent years, due to extreme drought events caused by extreme climate change, drought-resistant and salt-resistant vegetation also rapidly degenerates, and further, the river bank desertification and the ecological system destruction are promoted. Therefore, the reinforced riparian zone vegetation protection has considerable urgency and long-term ecological benefit. At present, most of river bank zone vegetation protection methods adopt methods such as flood irrigation of river water. The method has the defects of incapacity of enlarging and adjusting, large evaporation loss and the like at present, and the potential risk of salinization of the surface soil of the river bank can be increased. This results in the need for manual remedies in each dry period, resulting in high labor costs.

However, in the traditional water storage and sprinkling irrigation device, most of the water storage is exposed to the outside, the water storage is not closed, the water surface is exposed to the outside, the water storage is easily affected by the surrounding environment, and the water quality is easily polluted. Meanwhile, the water quantity in the dry area is large in evaporation, and water resources are easy to lose. The rainfall in the dry area is less and the period is unstable, and the traditional automatic sprinkler irrigation system for collecting the rainwater is difficult to be suitable for the river bank zone in the dry area. The high-water-level river water in the flood period caused by the ice and snow melting of river source is the most main collectable water source in the river bank zone of the arid region, but the storage and utilization technology of the resource is not yet proposed.
