“四位一体”农村能源生态模式,是遵循自然规律和经济原则,有利于农业生态系统物质能量转换、平衡的农村能源结构形式。它具有多学科的技术内容和综合性很强的特点,在农业生产综合协调发展方面起着重要作用,并以其多功能特点进入生态农业生产系统,发挥出极其重要的作用。 一、“四位一体”农村能源生态模式的基本原理和内容 “四位一体”农村能源生态模式以土地资源为基础,以太阳能为动力,以沼气为纽带,种植、养殖相结合,通过生物能转换技术,在全封闭状态下,将沼气池、猪禽舍、厕所、日光温室相连在一起,组成农村能源综合利用体系(如图1所示)。它是在同一块土地上,实现产气积肥同步,种植养殖并举,能流、物流良性循环,庭院经济与生态农业相结合的一种高产、优质、高效的农业生产模式。
The “four in one” rural energy eco-mode is a form of rural energy structure that is in line with the laws of nature and economy and is conducive to the conversion of the material and energy of agricultural ecosystems. It has multidisciplinary technical content and comprehensive characteristics. It plays an important role in the comprehensive and coordinated development of agricultural production and plays an extremely important role in its ecological agricultural production system with its multi-functional characteristics. I. Basic Principles and Contents of the “Four in One” Rural Energy Ecological Model The “four in one” rural energy eco-mode is based on land resources, using solar energy as a driving force, biogas as a link, planting and breeding, combining bioenergy Conversion technology, in a fully enclosed state, the digesters, pigs, toilet, solar greenhouse connected together to form a comprehensive utilization of rural energy system (Figure 1). It is a kind of high yield, high quality and high efficient agricultural production mode that combines production of gas and fertilizer simultaneously, cultivation and breeding simultaneously, energy flow, logistics virtuous circle, courtyard economy and ecological agriculture on the same land.
