摘  要:
The influence of different levelN, P and water on the growth and development of corn root system at seedling stage was studied with the method of regressive, optimum design. Well fitted quadratic regressive equations were obtained between dry weight, volume and number of roots with the levels of N, P and water. The optimum applying amount of N, P fertilizers and water was suggested.
