Productivity of crop-fruit ecological agriculture in middle-south Loess Plateau

Abstract

Abstract: With the Xipo,Feimahe and Nangou villages as test objects,the productive characteristics of crop-fruit ecological agriculture in the middle-south Loess Plateau were investigated.The results showed that the biomass productivity of a plant was different with its organs,the highest for grain or fruit,and followed by stem,leaf and root.In the crop-fruit ecological agriculture,the higher ratio the crop subsystem,the higher productivity its biomass,the lower economic productivity and lower economic value was; while the fruit subsystem was on the contrary.The productivity of livestock farming subsystem was in a lower level,which restricted the increase of the total ecosystem's productivity.Based on these results,a countermeasure of increasing the ecosystem productivity was put forward.

Key words: Productivity, Crop-fruit ecological agriculture, Loess Plateau
