Abstract: The effect of slurry on the yield, quality, and nutrition absorption of Chinese cabbage was determined.
Results showed that the yield of Chinese cabbage was enhanced significantly when slurry applied. Compared to the
chemical fertilizer treatment, the content of free amino acid increased, and the content of nitrate decreased for the activity
of nitrate reductase enhanced. The content of N and the accumulation of NPKCa increased compared to the control.
However, the agronomic nutrition use efficiency would decline with slurry application increasing. |
