| Abstract: |
| To find a suitable multiple cropping pattern for Shenyang area, matter production and resources use effi-ciency of three multiple cropping patterns was analyzed by the grey correlation analysis method. The results showed that the crop productivity, climate production efficiency, energy benefit, economic benefit and comprehensive benefit of the three multiple cropping patterns were obviously bigger than those of single spring maize system. The pure benefit of pota-to-silage corn was 25 462 Yuan hm2, which was 136% higher than that of single spring maize system; And the pure benefits of fresh food cor-silage com and wheat-silage corn were respectively 22 993 Yuan/hm2 and 14 216 Yuan/hm2, which were respectively 113% and 32% higher than that of single spring maize system. |
