The core issue of present development of agriculture and rural life in China is how to increase peasants' income considerably. Low income comes from the absent benefits from the second and tertiary industries within agriculture. The guiding principle of integrating rural primary, secondary and tertiary industries has recently been drawn up, while the achievement so far keeps unsatisfying, because of identical rural industries which can hardly form ‘pillar’ industry and because of the lack of means to promote the integration. This paper proposes an agriculture model of ‘whole links of agro-industry chain’, based on analyzing relevant experiences of ancient Chinese agriculture and foreign modern agriculture The content of such a new area includes full utilization of organic residues and wastes, growing dedicated energy plants(bushes and grasses) on marginal land, converting these two kinds of biomass into energy commodities and bio-based materials through biorefinery in situ or in outside scaled plants, as well as selling them. Such an innovative concept model is defined as ‘Second Agriculture’ in this paper.
