【摘要】 通过田间试验分析比较了莴苣、洋葱有机与无机生产系统的能流、经济流及对土壤环境的影响。结果表明,有机系统蔬菜的长势、产量、经济效益均高于无机系统;能量产投比有机系统受施肥种类影响很大;土壤微生物量有机系统高于无机系统。更多还原

【Abstract】 Energy flow, economic flow and their influence on soil environment in organic and inorganic vegetable production systems are analyzed. The results show that the vegetable’s growth,yield and economic benefit in organic system are all better than those in inorganic system, the energy output/input ratio of organic system was significantly impacted by the varieties of applied organic fertilizer. The soil microbiomass in organic system are higher than that in inorganic system.更多还原
