Two conventional rice cultivars with good taste quality,indica/xian rice Yangxizao and japonica/geng rice Exiang 2,were used to study the effects of wood vinegar and different nitrogen application on the yield and eating quality of rice. Under the conditions of 4 nitrogen fertilizer application levels (0,50,100,200 kg/hm2),spraying and not spraying wood vinegar were set. The results showed that comparing with non-application of wood vinegar,the wood vinegar application significantly increased yield under different nitrogen application conditions. Spraying wood vinegar significantly increased the yield of conventional japonica geng rice Exiang 2,especially under low nitrogen level. Spraying wood vinegar under different nitrogen application conditions significantly improved the processing quality of rice,and had a significant effect on the rate of brown rice and milled rice. It was also beneficial to improve the cooking and eating quality of rice,which can significantly increase the reduction value of rice,reduce the disintegration value,and then increase the taste value of rice. The effect of vinegar on the eating quality of rice was more obvious when the wood vinegar applied under low nitrogen level.
