Features: This book is divided into 10 chapters. Chapters 1 and 2 introduce the composition and working principles of drip irrigation and fertigation systems; Chapter 3 discusses the solubility and compatibility of commonly used fertilizers in drip irrigation; Chapter 4 covers plant and soil nutrient diagnosis and fertigation irrigation regimes under drip irrigation conditions; Chapter 5 explores chemical clogging in drip irrigation systems and its preventive measures; Chapters 6 and 7 present experimental research findings on design and operational parameters of different drip irrigation systems, as well as water movement, wetted body geometry, and the distribution of nitrate and ammonium nitrogen under various soil conditions; Chapter 8 uses commercial software HYDRUS-2D to simulate the water and nitrogen movement patterns under drip irrigation and fertigation conditions, achieving satisfactory results in water movement simulation but revealing that deterministic models for nitrogen movement still have many unresolved issues requiring further research; Chapter 9 establishes an artificial neural network model to simulate the distribution of nitrate nitrogen under drip irrigation and fertigation conditions, aiming to explore a new approach for modeling nitrogen distribution in such complex scenarios; Chapter 10 introduces field experimental results on the water requirement patterns of spring corn under drip irrigation and fertigation conditions in arid and sandy regions. This book is suitable for undergraduate and graduate students in water resources and soil science, as well as researchers, educators, and engineering technicians working in related fields.
