| In order to provide scientific instructions for the local agricultural production of hybrid corn, the affection of fertilizer on agronomic characters, yield-related traits, mass and economical production of hybrid corn were analyzed in the “3414”experiment.Meanwhile, the fertilizer effects of N,P,K were also analyzed in this experiment. The results showed that，the agronomic characters and yield-related traits of 13 treats were more or less higher than that of the control group; the magnitude effect of the three elements of fertilizer (N,P,K) on the traits in turn were weight per ear, grain number per ear, ear height, plant height, nevertheless，that on diameter of ear, rows per ear, ear length and 100-grain weight were comparatively small. Among the 14 treats, treat sixth(N2P2K2) got the highest yield, which was 661.3 kg per 667m2. Treat fifth (N2P1K2) possessed the best economical benefit. The highest net income lied in treat fourteenth (N2P1K1), which was 1 261.09 yuan, and the biggest ratio of output to input was 2.17, which existed in treat thirteenth(N1P2K1). |
