| Abstract: |
| The situation of fertilization for apple orchards was analyzed by using the investigation data of Central Shaanxi irrigation region and Weibei rain-fed region in Shaanxi province from 1994 to 2000 and evaluated by using the optimal fertilizing schemes. The main problems of fertilization in orchards were discussed. The results are as follows: (1) the input of chemical fertilizer is unbalanced seriously among different farms, and the ratio of potassium fertilizer applied to apple need to be increased; (2)the rate of organic manure is decreasing; (3) the technology of fertilization need to be improved. |
