摘要
从籽粒苋的生物学、生态学特性研究分析表明,以籽粒苋为纽带的果园复合经营生态系统有较高的能量利用率,可有效提高初级生产力,降低系统人工辅助能的消耗,增加系统物质循环中利用环节,提高物质转化效率。并阐述了3种以籽粒苋为纽带的果园复合经营模式及其结构特征。
The analysis on the biological and ecological characteristics of Grain amaranths illustrates that the ecosystem of orchard taking Grain amaranths as a link has higher efficiency of utilizing energy, can increase primary output and reduce the consumption of auxiliary energy. It can increase the knot of utilizing material during matter recycling and efficiency of material changing. The study also states three models of orchard taking Grain amaranths as a link and their characteristics on structure.
