Difference in Energy Input and Output in Agricultural Production under Surface Irrigation and Water-Saving Irrigation: A Case Study of Kiwi Fruit in Shaanxi

China’s kiwi industry has seen rising production costs and shrinking planting areas in recent years; at the same time, lack of professional standards leads to input redundancy waste factors process kiwifruit, which intensifies dilemma unsustainable agricultural production. This brought more serious challenges sustainable development industry. In order solve this problem clarify composition utilization efficiency energy study took Chinese kiwifruit as research object analyzed output under surface irrigation water-saving from perspective energy. The results show that traditional was 85.4 GJ/ha, 59.7 GJ/ha. Among all elements, mineral fertilizers accounted for highest proportion input, accounting 48.31%. Under irrigation, are 72.3 GJ/ha 62.3 GJ/ha; is also fertilizer. data envelopment analysis confirmed there a large amount Compared with technology effectively improved ratio (from 0.70 0.86), productivity 0.37 kg/MJ 0.45 kg/MJ) well net −25.8 −9.93 GJ/ha). Thus, promoting application increasing fertigation during necessary measures promote
