Abstract: In order to study the influence of different altitudes during the period of growth and yield of crops, by using the test method of planting of winter wheat in different altitude, 2012-2013 through at an altitude of 1600 m (mid levels area) and 1000 m (KU) of winter wheat planting test, on winter wheat growth period and yield factor analysis showed that, sowing date shifted to early 10 days at semi-mountain area than that of basin area. The days before the winter in both of semi-mountain area and basin area were almost same, but there was a big difference after reviving growth period in these two kinds of areas. The whole growth period of wheat in semi-mountain was 30 days longer than that in basin area. There was big difference of thermal time between the two kinds of area in tillering to beginning overwinter, beginning overwinter to reviving, jointing to booting, booting to head sprouting and head sprouting to flowering growth periods. The number of tiller and big tiller in semi-mountain area was over that in basin area. The spikelet number and dry matter in semi-mountain area was also over that in basin area. The theoretical and actual yield in semi-mountain area was higher than that in basin area. 2012-2013 winter wheat yield factor of half a mountainous area than in Hilly regions. This is related to vernalization stage of winter wheat winter temperatures, milky to maturity of the stay.
