Agricultural water resource is greatly limited in the Huang-Huai-Hai plain of China, a continental monsoon region in warm temperate zone, especially during winter wheat growth period. No sufficient surface water resources are available for irrigation while the traditional and mostly current irrigation regimes are not well made so far leading to water waste to a certain extent. The experiment was conducted to elucidate the effects of different irrigation treatments on water consumption characteristics, and nitrogen accumulation and allocation in wheat plants. The results may be helpful to determine a best irrigation regime suited for this region. The experiment was conducted in the field at the Agricultural Experiment Station (latitude 36°09′N, longitude 117°09′ E) of Shandong Agricultural University (Taian, Shandong Province, China) during the winter wheat growing season (from the fall of 2005 to the summer of 2006), which is located in the central zone in the Huang Huai Hai Plain of China. The winter wheat cultivar was Jimai 20. The experiment had seven treatments: no irrigation during the whole growth season (represented as W0); irrigated at jointing and anthesis stages, and irrigation amount was 30mm(W1), 60mm(W2), 90mm(W3), respectively; irrigated at jointing, anthesis and filling stages, and irrigation amount also was 30mm(W4), 60mm(W5), 90mm(W6), respectively. Each treatment had 3 replicates, with a plot of 1.5m 6m. We mounted the width of 1.5m isolation to put apart every plot. We used water meters to strictly control irrigation amount. Wheat seeds was sowed on October 10 in 2005, with plant density of 180 m-2. The results of this experiment showed that, with the increase in irrigation water amount, the total water consumption were reduced. The total water consumption amounts of treatment W2 and W4, with the highest yield and water use efficiency were 413.87mm, 362.15mm respectively; the ratio of irrigation amount, precipitation, and soil water consumption amount to total water consumption amount were 29%, 36.34%, 34.66%, 24.85%, 41.53%, 33.62%, respectively. And these compositions of water consumption ratio promoted wheat production and water use efficiency. Compared with treatment W2 treatment W4 increased the ratio of precipitation to total water consumption amount and reduced the ratio of irrigation amount to total water consumption amount. Through measuring soil water consumption amount of 0 to 200cm different layers during the whole growth, we found that deep soil layer water consumption amounts of treatment W0 and W1 were less and each soil layer water consumption amount of treatment W3, W5, W6 from 0 to 200cm were lower. Treatments W2 and W4 would take advantage of 120 to 200cm soil layer moisture, because of great water demand by increasing soil water consumption amount. Through determining nitrogen concentration, the grain nitrogen accumulation amount of treatment W2 was the highest. The proportion of nitrogen accumulation of treatment W1 and W4 was significantly higher than other treatments. For the treatments irrigated at filling stage, especially with irrigation amount of more than 30mm, the nitrogen translocation efficiency and contribution proportion of vegetative organs were reduced significantly. The grain protein content of treatment W4 was the highest. With the irrigation amount increasing, the grain yield first increased, thereafter reduced. The grain protein yield and grain yield of treatment W2 and W4 were not significantly different. The water use efficiency and protein water use efficiency of treatment W4 was significantly higher relative to other treatments. In conclusion, treatment W4 had higher grain yield and water use efficiency, it was suggested that treatment W4 may be the best irrigation regime in irrigation management practices.
