Abstract:
The interactions among N,P and water were studied in two soils of different textures in Beijing suburb plain in 1992-1994.The result was compared and analysed with the multiple regression method.It showed that both in loamy soil and sandy soil,water was the most important factor,followed by nitrogen and phosphorus,in the production of wheat.The effect of water was even more obvious in sandy soil.Nitrogen fertilizer promoted the water trait value W0,Wmax and We in sandy soil,but reduced them in loamy soil.Phorsphorus fertilizer had the opposite effect on water.The effect of soil water on N and P fertilizers showed the same feature as the interaction of fertilizers on water except at a stronger intensity.
Key words:
Interaction among N,P and water,
Soils,
