Abstract
The farmer participating evaluation under five experiments,including 10,12,14 rows upland rice intercropped with 2 rows,respectively and single cropping with 5 rows maize,were employed to optimize the intercropping model.Meanwhile,the Land Equivalent Ratio(LER) and the Relative Value of Testing(RVT) was analyzed.The results showed that the intercropping model of 14 rows intercropped with 2 rows maize presented the yield of 5 719.5 kg/hm2 and 8 701.2 yuan/hm2 income.Compared with single intercropping of upland rice,the yield increased 2 163 kg/hm2 and income increased 3 130.4 yuan/hm2,the increasing ratio was up to 52.9%.The LER was 1.37 and the RVT was 1,53.71.4% participated farmers considered that intercropping between upland rice and maize was a good intercropping model even it was higher input than single cropping of upland rice and like to select this model using in future.
