Based on 24 year rotation and fertilizer experiments
the effects of rotation and fertilization on the growth
yield and water consumption of spring maize were studied . Results showed that at the same fertilization level
leaf area
yield
and biomass of continuous cropping maize were higher than rotation treatment .Under the same rotation conditions
RT —NPM had the highest leaf area
yield
and biomass
RT —NPM was the second
and RT —NP was the lowest . Yield and biomass of the three treatments were significantly different . The averaged soil water content in 0—300 cm layer decreased firstly and then increased in different development stages and eventually fell to the lowest level in the silking stage . The order of treatments
by water consumption of spring maize
was CT —NPM >RT —NPM >RT —NPK >RT —P . The rotation maize had the highest water use efficiency
