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

Effect of wheat/maize and faba bean/maize intercropping on soil nitrate nitrogen concentration and accumulation;

Effects of nitrogen fertilization application and faba bean/maize intercropping on the spatial and temporal distribution of soil inorganic nitrogen

Effect of wheat/maize and faba bean/maize intercropping at 0,300,450 kg/hm2 nitrogen rate on water use in Hexi corridor of Gansu province were discussed, the results showed that during wheat flowering period, soil water content of intercropped maize were higher that that of solecropped at three nitrogen rate, intercropped wheat and faba bean .

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.
