间作对油莎豆根系分布及产量的影响

Effects of Intercropping on Root Distribution and Yield of Tiger Nut

为找出最适合与油莎豆间作高产的作物种类,以油莎豆为研究对象,在北疆地区滴灌条件下设置4种种植模式:油莎豆单作,大豆‖油莎豆,玉米‖油莎豆和棉花‖油莎豆,分别测定油莎豆农艺性状及根系参数,阐明间作对油莎豆产量及根系形成的影响,进而揭示油莎豆高产群体与其他作物的种间关系及其根系的分布规律,最终达到油莎豆种植高产、优质的目的。结果表明,棉花‖油莎豆,玉米‖油莎豆和大豆‖油莎豆均有间作优势,大豆‖油莎豆最佳。

To explore the most suitable intercropping crops with tiger nut,four planting modes were designed under drip irrigation:monoculture tiger nut,soybean and tiger nut intercropping,maize and tiger nut intercropping and cotton and tiger nut intercropping.Agronomic characters and root parameters of tiger nut were measured respectively,and then reveal the interspecific relationship between high-yielding population and other crops as well as the distribution rule of its root system,so as to achieve the goal of high yield and high quality finally.The results showed that:soybean and tiger nut intercropping,maize and tiger nut intercropping,and Gossypium hirsutum and tiger nut intercropping had intercropping advantages,while soybean and tiger nut intercropping were the best.
