Description

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). Users of this LCA dataset should apply it to understand the environmental impacts associated with different farming practices in greenhouse vegetable production. The data focuses on the production of eggplants but may be applicable to similar greenhouse crops. Users must consider the system boundary delineated from cradle to farm gate, including production of agricultural inputs, crop production, and transportation subsystems. Careful attention should be paid to methodological details such as pollutant emissions and energy consumption data collection, soil nutrient leaching measurement, and the use of specific analytical instruments as described. The dataset should not be applied outside the established system boundaries, and adjustments may be required for differing crop types or agricultural practices.

Technology

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.
