摘要
为实现定西市安定区“玉米不减产、大豆多收一季”的目标,对比研究了4种带状复合种植模式对作物生长、产量及资源利用效率的影响,筛选出最优栽培模式为区域推广提供依据。研究结果表明:“3+2”在生长势、产量及资源利用效率上均显著优于其他模式,其玉米株高、茎粗、LAI、单株产量、冠层透光率、水分利用效率和产量等显著高于其他处理,其大豆株高、分枝数单株产量、冠层透光率、水分利用效率和产量也高于其他处理。因此,在安定区可结合全膜双垄沟播技术,推荐“3+2”模式为大豆玉米带状复合种植主推技术。
To achieve the goal of"no reduction in maize yield and an additional harvest of soybeans"in Anding District,a comparative study was conducted on the effects of four strip intercropping models on crop growth,yield and resource utilization efficiency,and the optimal cultivation model was screened out to provide a basis for regional promotion.The research results showed that"3+2"was significantly superior to other models in terms of growth vigor,yield and resource utilization efficiency.Its maize plant height,stem diameter,LAI,single-plant yield,canopy light transmittance,water use efficiency and yield were significantly higher than those of other treatments.Its soybean plant height,branch number,single-plant yield,canopy light transmittance,water use efficiency and yield were also higher than those of other treatments.Therefore,in the stable area,the full-film double-ridge furrow sowing technology could be combined,and the"3+2"model was recommended as the main promoted technology for the intercropping of soybeans and maize in strips.
