向日葵与蚕豆和马铃薯间作对作物产量和水分利用效率的影响
Effects of Sunflower Intercropping with Fababean and Potato on Crop Yield and Water Use Efficiency
摘要
Abstract
The paper researched moisture absorption and utilization of crop in two kinds of intercropping patterns in agro-pastoral ecotone, including sunflower/potato and sunflower/fababean. Compared to monoculture sunflower, potato and fababean, we measured and analyzed soil water content from 0 to 140 cm soil layer and crop yield of intercropping crops in growth period, and quantified land equivalent ratio( LER), water use equivalent ratio( WER), evapotranspiration( ET) and water use efficiency( WUE) of different intercropping systems. The results showed that sunflower/potato and sunflower/fababean intercropping patterns can both improve the yield of intercropping and land productivity with intercropping advantage, and sunflower/potato pattern has more significant intercropping advantage. Intercropping can increase crop water consumption and make crops use deep water, which has an advantage over water-consuming crops. Sunflower/potato and sunflower/fababean patterns can both effectively improve water use efficiency of high-stem crop sunflower, with anincrease of 27. 1％-28. 8％ compared with monoculture sunflower, and sunflower/fababean pattern has more advantages of water use than sunflower/potato pattern.关键词
