摘要： 为了研究不同海拔高度对农作物生长发育期及产量的影响，通过采用对不同海拔高度的冬小麦对比种植试验方法，2012—2013年通过在海拔1600 m（半山区）和1000 m（川区）的冬小麦种植试验，对冬小麦生长发育期以及产量因素进行分析。结果表明：半山区冬小麦比川区早播种10天左右。冬前生长期山、川地各个生育期相差不大，翌年返青生长的拔节期以后川区冬小麦生育期比半山区明显提前。半山区比川区冬小麦全生育期长30天。分蘖—越冬开始、越冬开始—返青期、拔节—孕穗期、孕穗—抽穗期、抽穗—开花期各生育期阶段山、川积温相差较大。半山区冬小麦分蘖数及大蘖数均高于川区，半山区有小穗数大于川区，干物质累积量半山区高于川区。半山区冬小麦理论、实际产量均高于川区。由此得出，2012—2013年半山区冬小麦的产量因子高于川区，这与冬性冬小麦春化期的气温条件、乳熟—成熟期的天数等因素有关。

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.
