本文运用了生态经济学的原理,对草莓在有机和无机种植系统内能量流动、物质转化以及经济效益进行了比较研究。结果表明:两处理区施用几乎相同氮量的有机肥(175kg/hm ̄2)和无机肥(164kg/hm ̄2),其有机区草莓的生长发育、产量均明显好于无机处理区;有机草莓的光能利用率和氮素产出/投入分别比无机草莓提高了64.24%和57.72%;同时证明,优质有机肥可改善草莓的良用品质,并提高经济效益。
In this paper, the principles of ecological economics are used to compare the energy flow, material conversion and economic benefits of strawberries in organic and inorganic planting systems. The results showed that the organic matter (175kg / hm ~ 2) and inorganic fertilizer (164kg / hm ~ 2) with almost the same amount of nitrogen applied in the two treatment areas showed that the growth and development of strawberries in the organic area were significantly better than those in the inorganic area The light energy utilization rate and nitrogen yield / input of strawberries increased by 64.24% and 57.72% respectively than that of inorganic strawberries. At the same time, it was proved that high-quality organic fertilizer could improve the good quality of strawberries and increase the economic benefits.
