160 Cm soil layers by soil drill and Nmin concentrations in the soil were measured by flow analysis after CaCl2 extraction. The results showed that NO3--N is the major inorganic nitrogen form in orthic anthrosol soil, and there are no significant differences in soil Nmin accumulation between sole cropping and faba bean/maize intercropping at the co-growth stage.

在田间条件下于2006—2007年研究了不同氮水平下（N 0、75、150、225、300 kg/hm2）蚕豆/玉米间作体系与其相应单作体系土壤无机氮的时空分布规律，旨在为河西走廊灌区蚕豆/玉米间作体系的氮素管理提供理论依据。

On the basis of observation on the incident and transmitted photosynthetically active radiation of the winter wheat canopy under the monoculture and intercropping ways, the diurnal change of interception photosynthetically active radiation, the relationship between IPAR and leave area index, and the shading of the winter wheat were studied.

文章摘要：通过对单作和间作种植模式下作物冠层入射和透射光合有效辐射的观测，研究了不同种植模式下冠层光合有效辐射截获量的日变化规律及其与叶面积指数的关系以及冬小麦对预留行的遮荫作用。

By setting five kinds of poplar row spacing gradients and control, the yield distribution rules of three intercropping medicinal species were observed, namely Glycyrrhiza uralensis, Platycodon grandiflorum and Pinellia pedatisecta.

设置了5种不同毛白杨行距梯度和无林地对照，观测了不同毛白杨行距以及同一行距下的不同林地位置间作的甘草、桔梗、天南星3种药用植物的产量分布规律。

Yield for intercropping system is quadratically correlated with wheat competitiveness to maize.

适度提高小麦的竞争优势、特别是小麦开花期的竞争优势有利于间作群体整体产量的提高。

In comparison with monocropping, the amount of Si accumulation of wheat was increased by 33%, 41%, 51% and 18% at tillering, elongating, heading and maturing stages respectively intercropping.

与单作相比，间作小麦平均硅累积量在分蘖期、拔节期、抽穗期和成熟期分别提高了33%、41%、51%和18%，说明间作对硅的吸收累积具有显著优势。分蘖期、拔节期和抽穗期间作小麦硅的吸收速率显著高于单作。

The results were as follows:(1) The grain yield of wheat was significantly enhanced by P fertilizer and intercropping, while the one of intercropped maize was improved by both N and P fertilizers.

间作小麦增产的主要原因在于小麦具有明显地边行产量优势，在低氮情况下尤为如此，但是随着施氮量的提高，边行优势有降低的趋势

The changes of nitrogen content, free amino acid, C/N ratio and chlorophyll content of wheat in wheat-faba bean intercropping system were studied by pot experiment with 3 N levels 0, 75 and 150 mg Nkg^(-1 soil. The results showed that leaf nitrogen content of intercropped wheat was higher than that of monocultured wheat at 3N level at tilling and booting stages, but was lower at heading stages.

为了解小麦蚕豆间作系统中小麦氮同化物的变化特征，探讨小麦蚕豆间作提高作物抗病性的可能机制，通过盆栽试验的方法，研究了小麦植株全氮含量、叶片游离氨基酸、叶片C/N比和叶绿素含量的动态变化及供氮水平对其的影响。
