[Abstract]
Addressing issues such as water scarcity and low fertilizer utilization efficiency in soybean production in dryland farming areas of Gansu Province, a technical regulation of soybean fertigation with drip irrigation under mulching film has been developed through years of experimental research and large-scale demonstration. This protocol covers various aspects including scope, normative references, terms and definitions, drip system composition and equipment installation, land preparation and fertilization, sowing methods, field management, pest and disease control, harvesting, recycle residual film and pipelines, etc. This technique offers advantages such as water and fertilizer savings, yield increase and efficiency improvement, as well as soil temperature accumulation and moisture conservation compared to conventional irrigation methods. Its application creates favorable water and nutrient conditions for soybean growth, helps improve the soil microenvironment, and thereby enhances both soybean yield and the efficiency of water and fertilizer utilization.
