Effects of Tillage Practices and Plastic Film Mulching on Soil Temperature, Dry Matter Production, and Yield Formation of Maize in a Cool Region

Limited thermal resources in the cool regions of Northeast China restrict maize growth and yield formation. A two-year field experiment was conducted in Dunhua, Jilin Province, China, during 2024–2025 using four tillage practices—deep rotary tillage (SX), deep harrowing (SB), dee...
