【摘要】 有机农业被认为能够减少与化学农业有关的有害物质影响。然而,有机农业是否能够养活一个不断增长的世界人口,存在着很多争论。我们假设通过有机农业的改良可以生产出足够的食物,减少环境污染。在弘毅生态农场(HOF),针对有机生物多样性管理模式(BMOF)与化学农业模式(CF),开展了8年以上的比较研究,探索有机农业生物多样性管理下土壤有机质和经济效益变化。将作物生产与牲畜养殖有机结合起来,最大限度地利用每种农产品的副产品,避免外源化学物质投入。在土壤特性改善、病、虫、草害防治方面,取得了明显的生态效益,并提高了作物产量。经过8年试验,农作物产量逐步稳定增长,生态农场纯收入增长9.6倍。2014年和2007年,HOF净收入分别为258827美元和24423美元。因此,BMOF不仅可以养活更多的人口,而且提高农业生态系统适应能力,同时获得更高的经济效益。

Abstract  Organic farming (OF) has been believed to be capable of curtailing some hazardous effects associated with chemical farming (CF). However, debates also exist on whether OF can feed a world with increasing human population. We hypothesized that some improvements on OF may produce adequate crops and reduce environmental pollutions from CF. This paper makes comparative analysis of crop yield, soil organic matter and economic benefits within the practice on Biodiversity Management of Organic Farming (BMOF) at Hongyi Organic Farm (HOF) over eight years and between BMOF and CF. Linking crop production with livestock to maximal uses of by-products from each production and avoid enobiotic chemicals, we have achieved beneficial improvement in soil properties, effective pest and weed control, and increased crop yields. After eight years experiment, we have obtained a gradual but stable increase in crop yields with a 9.6-fold increase of net income. The net income of HOF was 258,827 dollars and 24,423 dollars in 2014 and 2007 respectively. Thus, BMOF can not only feed more population, but also increase adaptive capacity of agriculture ecosystems and gain much higher economic benefits.
