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%。
Field trials were conducted to study the effects of maize intercropping with different crops on corn growth, nutrient accumulation and yield. The results showed that maize intercropping with different crops could improve the leaf chlorophyll content, photosynthetic characteristics, NPK accumulation and yield of maize. Among the four intercropping practices, maize peanut and maize soybean intercropping increased the chlorophyll content and photosynthetic characteristics of maize leaves significantly. The accumulative nitrogen, phosphorus and potassium accumulation of maize and soybean intercropped with nitrogen had the largest accumulation of nitrogen, Up to 224.6 kg / hm2. The accumulation of phosphorus and potassium in corn-sweet potato intercropping system was the highest, accounting for 117.72 and 352.84 kg / hm2, respectively. In terms of yield, yields of maize sweet potato intercropping and maize intercropping were 75.7% , 47.5%.
