果牧结合生态农业模式的综合效益试验研究

Effects of Ecological Agricultural System Comprising of Pear,Ryegrass and Goat

三峡库区生态环境的质量直接关系到三峡工程的长治久安,三峡库区属我国典型的内陆腹地农业经济类型区,生态农业的发展是该区农业现代化的必然选择。研究通过2000～2001年于三峡库区的开县进行不同生态农业模式效益的田间对比试验,结果分析表明,果牧结合(果-草-羊)的生态农业模式与单纯果园、果-菜结合等传统的农业模式相比,不但具有显著的经济效益、较好的社会效益,而且能显著改善土壤物理性状,增强土壤保蓄水力,提高土壤肥力;同时能有效地减少果园病虫发生,减少田间杂草的多样性,从而维护农业生态环境。

Based on the contrast design, field experimentation was carried out between 2000 and 2001. The study showed that economic, ecological and social benefits of a typical ecological agricultural system comprising pear, ryegrass and goat were higher than those of either the traditional cropping pattern of peach and potato or the pure peach orchard. The ecological agricultural system could notably increase the economic harvest and improve the soil structure, water storage and fertility. Moreover, it could significantly control the weed and pest so that it can reduce or limit the application dosage of herbicide and pesticide 
