Progress of Deficit Mulched Drip Irrigation for Potatoes

Submembrane drip irrigation offers several key benefits, including efficient water and fertilizer usage, strong adaptability to various environments, a reduction in pest and disease pressures, and increased crop yield and income. Research shows that this irrigation method can reduce water consumption by over 80%, enhance land use efficiency, decrease labor requirements, and improve water resource utilization. This paper examines the development and application of sub-film drip irrigation for potato cultivation under controlled deficit irrigation conditions. The goal is to enhance potato yield, improve quality, and optimize water usage efficiency, ultimately contributing to increased productivity and economic benefits for agricultural production.
