摘要
玉米大豆套种有利于玉米与大豆之间和谐共生及充分利用养分和水分资源,具有明显的产量优势,可提高系统产量和土地的当量比率。为了探寻玉米大豆套种模式下的水肥一体化的最佳模式,为玉米大豆套种的种植提供理论依据及技术指导,对水肥一体化系统关键部件进行了设计、选型及田间试验。结果表明:采用适宜的水肥一体化灌溉方式,确定合理的套种比例,有利于发挥套种的群体产出能力和效益。
Corn and soybean interplanting is conducive to the harmonious symbiosis between corn and soybean,making full use of nutrient and water resources,and has obvious yield advantages.To improve the system output and the equivalent ratio of land,in order to explore the best mode of water and fertilizer integration under the corn and soybean intercropping mode,provide theoretical basis and technical guidance for the planting of corn and soybean intercropping.This study through the design and selection of key components of the integrated water and fertilizer system,through the field test results show that the use of appropriate water and fertilizer integrated irrigation to determine a reasonable ratio of interplanting,is conducive to the performance of the group’s output capacity and benefits.
