基于生态农业的蔬菜大棚可持续化种植研究

Study on Sustainable Planting of Vegetable Greenhouse Based on Ecological Agriculture

以生态农业蔬菜大棚持续化种植过程为研究对象,通过对种植过程中的资源循环利用过程进行分析,建立一种基于蔬菜种植、生猪饲养及沼气生成为一体的生态农业蔬菜种植大棚,可对蔬菜种植时产生的废弃物进行堆肥发酵处理,生成沼气用于取暖照明,发酵液及残渣用于喂猪或有机肥添加,降低种植过程中废弃物排放,形成一种生态化持续种植模式。分别对生态蔬菜大棚和传统蔬菜大棚的投入产出和投入收益进行对比,结果表明:生态蔬菜大棚所产生的经济效益明显高于传统蔬菜大棚,且废弃物排放少。

This paper takes the sustainable planting process of ecological agricultural vegetable greenhouse as the research object,through the analysis of the process of resource recycling in the planting process,establish an ecological agricultural vegetable planting greenhouse based on the integration of vegetable planting,pig feeding and biogas production,compost and ferment the waste produced during the vegetable planting,generate biogas for heating and lighting,The fermentation liquid and residue are fed to pigs or added to organic fertilizer to reduce the waste discharge in the planting process and form an ecological and sustainable planting mode.Comparing the input-output and input-output of ecological vegetable greenhouse and traditional vegetable greenhouse respectively,it shows that the economic benefit of ecological vegetable greenhouse is obviously higher than that of traditional vegetable greenhouse,and the waste discharge is less.
