Description

The life cycle of winter wheats-summer maize rotation system mainly includes three stages: raw material mining and transportation, agricultural materials production and transportation, and crop planting, including coal, oil, natural gas, electricity and other raw materials mining and production, land resource utilization, fertilizer, pesticide and other agricultural materials production related energy consumption and pollutant emission. Including CO2, NH3, SO2, CH4, N2O and CO [11]. The environmental impact of plant equipment, construction facilities, production of transport tools and transportation of raw materials associated with the system is not considered. Users of this life cycle assessment data should consider the data within the context of agricultural production in the Northwest China region, especially in the analysis of farming systems involving crop rotation of winter wheat and summer maize. Attention should be paid to the boundaries of the system described, which includes raw material extraction, transportation, and crop cultivation, but excludes the environmental impacts of facility and equipment production, infrastructure building, and raw material transportation infrastructure. It is advisable for users to account for these exclusions in their overall environmental impact assessment and to not use this data in isolation when considering broader environmental implications.

Technology

The research on the resource utilization and environmental emission of winter wheat-summer maize rotation system from raw material extraction, processing and transportation to agricultural materials production and crop planting process is to provide decision-making basis for the production and environmental management of the whole process of winter wheat-summer maize rotation system. The life cycle assessment of agricultural products starts from the mining of ore and energy and ends in the output of crop planting, including the output of agricultural products and pollutants. Land resources are the basis of all production activities and directly enter the agricultural system. In this study, 1 t of crops were evaluated as functional units
