The trial Ziziphus jujuba 'Zhanshanmizao' as test materials, test its dormant stage breaking dormancy select different concentrations of potassium nitrate (3%, 6%, 9%), the control of water treatment, study the changes of water, organic substances (starch, soluble sugar, soluble protein, free amino acid). Then, measure the fruit quality, the effect of potassium nitrate (KNO3) with different concentrations on breaking forced dormancy of Ziziphus jujuba 'Zhanshanmizao' trees were compared. The

The results showed that in the forced dormany period (form 30 th Januaryto 14 th February) the effect on potassium nitrate at 6 % breaking forced dormancy were better than others, they can improve the ratio of the free water and the bound water significantly. Change the content of organic substances composition rapidly. KNO3 (9%) was largely ineffective or even inhibited in breaking dormancy. By analysis the fruit quality, we think the effects of KNO3 at 6% on breaking forced dormancy of Ziziphus jujuba 'Zhanshanmizao' was the best.
