Effect of wheat/maize intercropping and nitrogen fertilizer on water use;

Effect of wheat/maize intercropping on plant nitrogen uptake and soil nitrate nitrogen concentration;

Effects of nitrogen fertilizer application and irrigationlevel on soil nitrate nitrogen accumulation and water and nitrogen use efficiency for wheat/maize intercropping

Intercropping advantage and contribution of above-ground and under-ground interactions in wheat-maize intercropping;

Methods We employed a micro-plot experiment and root barriers in a wheat-maize intercropping system with or without maize plastic sheet mulching.

hm~(-2)), wheat-maize intercropping soil NO3--N content and distribution with the increase in nitrogen application rate increased, and in different growth stages of different crops in different soil depth and bring a certain degree of regularity there.

Effect of long-term fertilizer application on yield, nitrogen uptake and soil NO~-_3-N accumulation in wheat/maize intercropping;
