Abstract: This article collects meteorological information of Taihang Mountain.Through comparison with high quality apple production area in and out of China,the results are as follows: Weather conditions such as annual average temperature,frost-free period,the extreme low temperature and temperature in growing season are all feasible for apple production;Area which altitude above 500 m is comparative cool in Summer.Its high temperature is below 35℃ usually,few days over 35℃,and everyday high temperature duration is short.Spring and Autumnal shoot showed unobvious boundaries.These conditions are feasible for apple growth;High altitude,large temperature difference between day and night,and full ultraviolet exposure are all suitable for photosynthesis product accumulation and fruit color enhancement;Annual rainfall in Taihang Mountain is 500-600 mm.Though its total rainfall is lower but it is able to meet the basic requirement of apple.It is provide basic for water deposition and can solve the problem of uneven rainfall distribution;The disadvantage environmental conditions for free-pollutant apple developing in Taihang Mountain: Rainfall distribution is imbalance,the rate of change is large,and the results are partial or seasonal drought;Extreme temperature is above 40℃ in partial region of low altitude,and its 3.9% higher than upper limit index which infect apple yield and fruit quality;Disastrous weather occurred more frequently in partial area such as drought injury,flood,hail and wind damage.

Key words: Taihang mountain, Apple, Meteorological condition
