Abstract: A soil pot experiment was taken to study the effects of Nano- bentonit coated urea on the yield, nutrient absorption, nitrogen fertilizer use efficiency, leaf chlorophyll content and quality indexes of cabbage. The results showed that nano-bentonit coated urea could significantly improve the yield of cabbage and the accumulation of nutrients, so as the nitrogen use efficiency. Comparing with pure urea, the treatments applied 15% nano-bentonit coated urea while the content of nitrogen decreased about 10% and 20% , the nitrogen use efficiency has also been respectively improved about 7.9%、8.3%; the treatments applied 20% nano-bentonit coated urea while the content of nitrogen decreased about 10% and 20% , the nitrogen use efficiency respectively improved about 3.6%、12.6%. The cabbage chlorophyll content of all the nitrogen treatments are significantly higher than that of the non-nitrogen treatments, and cabbage chlorophyll content in the treatments applied nano-bentonite coated urea was higher than that in the treatment applied conventional urea, but the difference was not significant.
