采用根箱隔网盆栽方法模拟研究了玉米／花生间作对花生吸收利用铁营养的影响。用30μm尼龙网将聚氯乙烯制作的根箱分为根室和外室，模拟了玉米单作、花生单作、玉米／花生间作三种情况。结果表明，间作对花生的铁营养状况有很大的影响。当花生与玉米间作时，花生地上部不表现缺铁现象；而花生单作则表现出严重的新叶缺铁黄化现象。间作花生新叶的全铁含量是单作的1．8倍，单作新叶活性铁含量仅是间作的47．2％，叶绿素含量是间作的25．3％。间作显著促进了花生对铁的吸收，使花生不同的部位的含铁量高于单作，从而提高了花生的光合速率；同时间作花生对铁的利用效率明显增加，花生子粒中铁的吸收量是单作的两倍多。
The effects of corn / peanut intercropping on the nutrient absorption and utilization of peanut were studied by using root box netted potted plants. The root boxes made of polyvinyl chloride were divided into root chamber and outer chamber with 30μm nylon mesh. The simulation of three kinds of corn single crop, peanut single crop and corn / peanut intercropping. The results showed that intercropping had a great influence on the iron nutrition status of peanut. When peanut and maize were intercropped, the peanut did not show iron deficiency in the shoots, whereas peanut showed severe new iron deficiency and yellowing in the shoots. The total iron content of intercropped peanut new leaves was 1.8 times that of single intercropped peanut. The content of active iron in fresh intercropping leaves was only 47.2% of the intercropping and the chlorophyll content was 25.3% of the intercropping. Intercropping significantly enhanced the absorption of iron by peanut so that the iron content of different parts of peanut was higher than that of single intercropping, which increased the photosynthetic rate of peanut. Meanwhile, the utilization efficiency of peanut for iron increased obviously. The absorption of iron in peanut More than twice as many as a single.
