Abstract

Three non-heading Chinese cabbage varieties were selected to study the effect of light intensity,fertilization amount and variety on the nitrate content and yield by multiple analysis of variance and correlation analysis.The results showed that all of the light intensity,fertilization amount and variety had significant impact on nitrate content and production of non-heading Chinese cabbage.The leaf and petiole nitrate content of non-heading Chinese cabbage decreased with the enhancement of light intensity,and the yield improved with increase of light intensity,the correlation coefficient being-0.574,-0.314,0.508,respectively.Moreover,the proper increase of fertilization amount could significantly improve the yield(r=0.433),but lead to a lot of nitrate accumulation.Meanwhile,the variety also had effect on nitrate content and production of non-heading Chinese cabbage.
