Abstract:The adaptability of introduction of Olive trees in their introduction into the Hanzhong area was investigated regarding to ecological factors. Through analysing the conditions of the main producing areas of Olive trees, we chose several from a lot of ecological factors as follows: the temperature and rainfall in the Hanzhong area, particularly the annum distribution of precipitation, length of solar radiation and soil condition. The result of study showed that particular attention should be given to the drainage in raining season, soil loosening, regualation of pH value and application of calcium, phosphorus, boron etc. and breeding of new cultivars which are particularly suitable to the local conditions of the Hanzhong area.
