摘要
为筛选陆稻玉米最佳间种植模式,2008年在普洱市进行了净作陆稻、每10行、12行陆稻间作2行玉米、14行陆稻间2行玉米、净作玉米5种处理的农户参与式认可度评价试验,并对试验进行了土地LER、RVT分析。结果表明,14行陆稻(模式F)间2行玉米实收复合产量5719.5 kg/hm2,产值8701.2元/hm2,较净种陆稻增产2163 kg/hm2,增产值3130.4元/hm2,增52.9%,模式FLER值1.37、RVT值达1.53,增产效果好;71.4%的农户认为陆稻间作玉米,虽然投入有所增加,但产量较单种陆稻高、效益好、劳动力投入不增加,愿意选择这种间作模式。
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.
