Abstract
Description
Technical Field
[0001] This utility model relates to an irrigation canal structure with an ecological filtration structure. It is applicable to the field of water conservancy and irrigation technology. Background Technology
[0002] Irrigation of plants requires the construction of irrigation canals to irrigate the plants grown in the soil. By directly excavating irrigation canals in the land, water can easily seep into the soil, replenishing it and increasing its water storage capacity. However, because plants require the application of chemical fertilizers and pesticides during cultivation, these substances can easily seep into the irrigation canals and flow into downstream rivers. The nitrogen and phosphorus nutrients, along with other pollutants contained in these fertilizers and pesticides, will affect the water quality of the rivers and also lead to the loss of nutrients from the soil.
