| 摘 要： | 本文针对江淮地区农业生态条件、种养业链接现状,通过应用单位耕地年产可消化生物量(DBYHY)新理论,提出江淮地区不同生态条件下可实施并具有代表性的一些DBYHY生产模型,并通过总消化养分校对公式(TDNc)测算了含有秸秆与牧草在内的各模型的TDNc数值,以说明秸秆与牧草在江淮地区农业结构调整中的替粮增值作用,以供将来深入研究秸秆与牧草的无公害饲用化对优化本地农业结构,提高土地生产力的影响作参考.

| Abstract: | The research analyzed the ecosystem and agricultural structure in area between the Changjiang river and the Huaihe river first.The new term Digestible Bio-mass Yield per Hectare per Year(DBYHY) was given.Some DBYHY practice models were established for the first time,and the dates from the correct Total Digestible Nutrients(TDNc) formula was taken out in order to confirm the importance of forage used in optimizing agri-structure and improving farmland value in the area. |
