Abstract:
Rape was used as test material，the effects of different organic manure treatments on nitrate and nitrite contents in rape leaves at different times(before engraftment,engraftment after 30 days and before harvest) were studied.The results showed that the contents of nitrate and nitrite increased significantly when earthworm fertilizer was used alone.However the combining of 2 000 kg earthworm fertilizer and 6.25 kg bamboo organic fertilizer per 667 m2 could reduce the contents of nitrate and nitrite by at least 40%，which was much better than the national standard.
