草莓有机与无机种植系统能流和经济流的比较研究

通过３年田间试验，比较分析了草莓有机与无机种植系统的能流、经济流及对土壤环境的影响。结果表明，有机系统草莓产量、经济效益均高于无机系统；有机系统能量产投比仅为无机系统的２５％，但投入的绝大部分为可再生能源；有机系统土壤有机质、微生物量高于无机系统，具有更好的土壤条件

A Comparative Study of Energy Flow and Economic Flow of Organic and Inorganic Strawberry Production Systems.

The energy flows and economic flows of organic and inorganic strawberry production systems and their influences on soil environment are discussed on the basis of field experiments. The results of the study show that the fruit yield and the economic efficiency of organic system were both higher than that of the inorganic system. Though, the energy output/input rate of organic system was only 25% of that of the inorganic system, the energy inputted to the organic system was mostly renewable energy, and the contents of organic matter and micro biomass in soil of organic system were higher than that of the inorganic system, it indicates that the soil environment of the organic system is better than that of the inorganic system.
