| 摘 要： | 通过盆栽试验,研究玉米、大豆间作及相应单作不同时期氮素吸收利用及生物学产量的差异。结果表明,间作对玉米的氮素吸收利用和生物学产量增加有较明显的促进作用,间作玉米氮素养分吸收量比相应单作提高57.53%,生物学产量提高47.02%. 而大豆的吸氮量只比相应单作降低1.21%,生物学产量降低14.56%.

| Abstract: | Pot experiments were conducted to investigate the nitrogen uptake and utilization and biomass yield in soybean and maize intercropping or mono culture system. The results showed that the obvious facilitation of nitrogen uptake and biomass was got by intercrop. The nitrogen uptake amount and biomass of intercropped maize increased 57.53% and 47.02% respectively, compared with those monocroped maize, The nitrogen uptake amount and biomass of intercropped soybean were 1.21% and 14.56% lower than those mono soybean. |
