Abstract: 【Objective】 To study and evaluate the cotton cost-saving and benefit-increasing technical system. 【Method】 The AHP analytic hierarchy process was used to construct the model to evaluate the use effect of the cotton-based synergy technology system from multiple perspectives. 【Result】 The yields of the demonstration area of cotton-based synergy technology system in Shawan County in the 2016 and 2017 were 0.6 kg/667m² and 0.63 kg/667m², respectively, which was much higher than the average output of 0.2 kg/667m², 0.22 kg/667m² in Tacheng area. In other words, they were 198% and 189% higher than the average yield in Tacheng area, respectively. The importance of the main factors (measures) affecting Shawan cotton production was scored by the AHP model, and the economic benefit score was 0.776,6. The resource saving score was 0.154,9, and the disaster prevention and mitigation score was 0.068,5. In the year 2016 and the year 2017, through cooperation with cooperatives, the company increased the income by 1.456 million yuan, through sophisticated seeding, 273,000 yuan cost was saved and the utilization efficiency of nitrogen, potassium and phosphate fertilizer were increased by 4.1 times, by 3.9 times and by 4.3 times through soil testing formula and precise fertilization, respectively. Cotton production was mainly affected by meteorological disasters such as low temperature, strong winds and heavy rain.【Conclusion】 The use of the cotton-based synergy technical system can effectively increase cotton yield. Ranking of the importance of each factor in the evaluation of cotton cost-saving and efficiency-increasing technical system: economic benefit > resource conservation > disaster prevention and mitigation. Through the cooperation with cooperatives, sophisticated sowing, soil testing formula and sophisticated fertilization, the cost of cotton planting can be effectively reduced, and the yield and economic benefits of cotton can be improved. Climate disasters have a certain impact on cotton planting, but in general, the impact on the demonstration area is small.
