| 摘 要： | Regressive models were obtained by employing “311-B” and “3414” optimal regressive desingns through 5-year (1993-1997) field experiment,and by datum processing with computer.These models express the relationships between corn yields in high,middle and low yield areas and N,P,and K application rates in black soil.By analysis to the models,the fertilizer application rates for maximum yield and optimal yield were achieved.

| Abstract: | Regressive models were obtained by employing "311-B" and "3414" optimal regressive desingns through 5-year (1993～1997) field experiment,and by datum processing with computer. These models express the re- lationships between corn yields in high,middle and low yield areas and N,P,and K application rates in black soil. By analysis to the models, the fertilizer application rates for maximum yield and optimal yield were achieved. |
