The solar greenhouse used in the experiment is an arch type with a length of 60 m and a width of 7 m. In the greenhouse, a variety of vegetables were rotated (two crops a year). In this study, eggplant seeds grew from March to August every year, and the experiment was carried out for the period of 4 years (2013 to 2016). Three treatment modes were set up in the experiment: (1) Conventional mode: the traditional greenhouse management mode of local farmers was adopted, mainly chemical fertilizer was applied, and a small amount of organic fertilizer was applied. ② Comprehensive mode: the amount of organic fertilizer and chemical fertilizer applied is 50% of the amount applied in organic and conventional mode, respectively. The biological control method is mainly used for disease and pest control, and low-toxicity and low-residue chemical pesticides are used for treatment in severe cases. (3) Organic mode: According to the production standards of organic vegetables, only organic fertilizers (compost and chicken manure) are applied, and chemical fertilizers and pesticides are not used. Agricultural measures and physical control of pests and diseases are mainly used (such as using yellow board to lure and kill, insect control nets, etc.). The nitrogen application amount of the integrated and organic models was the same as that of the normal scale model, and the irrigation conditions of each treatment were consistent. The irrigation method was large flood irrigation (Table 1). When using this dataset for life cycle assessment, consider the system boundary as defined from cradle to farm gate. This includes agricultural input production, crop production, and transportation subsystems. Exclude the processes related to infrastructure construction, agricultural machinery production, vegetable consumption, and waste emissions. Pay attention to the methodological details provided for data collection and measurements, such as the static chamber method for nitrous oxide, free-flow leaching for soil nutrients, and ICP-MS for heavy metals in organic fertilizers. Ensure correct referencing of the research results from the provided literature for inventory analysis, specifically Liang Long [22] and [19] for detailed measurement processes.


The experiment used a 60 m long and 7 m wide arched greenhouse for the cultivation of various vegetables in rotation (two crops per year). The study focused on the growth of eggplants from March to August each year, conducting a 4-year experiment from 2013 to 2016. Three treatments were applied: conventional, integrated, and organic.
