Abstract

Effects of Chelating Plant Nutrients on the yield and quality of flowering Chinese cabbage and lettuce were studied by field experiment.The results showed that the 600-time spraying had a better effect on yield.The 667 m2 yield of 600-time sprayed flowering Chinese cabbage and lettuce were 879 kg and 2 304 kg,increasing by 11.9% and 22.6% with the control,respectively.The Vc content and soluble sugar content in flowering Chinese cabbage and lettuce of the treatment were significantly increased,but the nitrate content were decreased.It was suggested that application of chelating plant nutrients at 600-time spraying could received significant increment in yield and better quality.
