通过田间小区试验,研究玉米与不同作物间套作方式对玉米生长、养分累积及产量的影响.结果表明：与玉米单作方式相比,玉米与不同作物间套作更能提高玉米的叶片叶绿素含量、光合特性、植株氮磷钾养分累积以及产量.4种间套作方式中,玉米花生、玉米大豆间作在对玉米叶片叶绿素含量及光合特性方面提高幅度较大;植株氮磷钾养分累积方面,则以玉米大豆间作处理的氮素累积最大,可达224.6 kg/hm2,以玉米红薯套作处理的磷、钾养分累积最大,分别为117.72、352.84 kg/hm2;产量方面,玉米红薯套作、玉米大豆间作较玉米单作增产率分别达75.7％、47.5％.

Using field plot test to research the effects of maize with different crops intercropping mode on gTowth,nutrient accumulation and yield of maize. The results showed that compared with maize monoculture way, maize intercropping with different crops can improve the corn leaf chloro- phyll content, photosynthetic characteristics, nutrient accumulation and yield. Four kinds of intercropping mode,33, T4 increased of corn leaf chlo- rophyll content and photosynthetic characteristics; T4 got nitrogen accumulation to be the largest which was 224.6 kg/hm2 ,meanwhile,33 made process of P, K nutrient ac...
