| 摘 要： | 为优化硫酸盐盐碱地棉花花生种植模式和提高单位土地面积综合经济效益，本研究以‘鲁棉研37 号’和‘花育36 号’为供试材料，在高唐硫酸盐盐碱地条件下，通过两年大田试验分析了棉花花生不同间作种植模式下作物产量、单位面积的土地当量比、种植成本和效益。结果表明，在试验点的气候条件下，棉花花生不同种植模式中两种作物产量存在年际间差异；棉花花生2:4 和4:8 间作种植模式的土地当量比、总效益、总成本和净效益均较高，其中4:8 种植模式的最高。棉花花生4:8 大小幅间作种植，年际间换带轮作，可作为当地棉花花生复合种植的最优配置。

Effects of Cotton-peanut Intercropping System on Yield and Economic Benefit in Saline-alkali Soil |
| |
| Abstract: | To optimize cotton and peanut crop pattern and improve comprehensive economic benefit per unit area of land in sulphate saline- alkali soil, cotton‘Lumianyan37’and peanut‘Huayu36’were used as materials, in the sulphate saline-alkali soil in Gaotang County, yield, land equivalent ratio per area, planting cost and economic benefit were analyzed through two-year field trial. The results showed that the yield of cotton and peanut had interannual difference under local climatic conditions, and the land equivalent ratio, the total economic benefit, the total cost and the net economic benefit of cotton peanut 2:4 and 4:8 cropping pattern were relatively high, and those of cotton peanut 4:8 cropping pattern were the highest. The large and small intercropping system of cotton peanut 4:8 and annual rotation could be chosen as the best allocation for cotton-peanut compound cultivation. |
