Abstract
Based on the long-term field experiments located in Hailun agricultural ecology station of Chinese Academy of Sciences,meteorological data and soil water content monitored by neutron probe were used to analyze the effect of different fertilizer treatments including no fertilizer(CK),chemical fertilizer(NP)and chemical fertilizer plus organic matter(NPM),on water consumption,soil water supply and water use efficiency(WUE)under rainy year(2006),normal year(2008)and drought years(2001 and 2004).Water consumption rate of soybean reached the peak at flowering-podding stage in views of four years' observation.Total water consumption of soybean was increased under fertilizer treatments,compared with CK,NP and NPM were increased by 0.92% and 2.21%,respectively,and this effect was more significant in drought years.Soil water supply was another important resource for water consumption of soybean with exception of precipitation.The precipitation from podding to mature was the lowest among whole growth period,and soil water supply of NP and NPM were increased by 11.72% and 23.8%,respectively.The WUE of soybean was showed in the order of CKNPNPM regardless of precipitation patterns,and increasing trend of WUE of soybean was observed with the decreasing of precipitation.Therefore,utilization of organic fertilizer can effectively regulate soil water supply,alleviate the drought stress result from seasonal precipitation,enhance soybean WUE,and make full use of soil water resource.
