利用阿勒泰基准站1980—2011年观测资料,进行了阿勒泰市春小麦发育期和光热资源变化,及各发育期日期与≥0℃积温、日照时数的相关性研究。结果表明:全发育期天数的变化呈减少趋势,分蘖、乳熟期、全发育期天数均通过了(P<0.01)显著性检验;全发育期≥0℃积温和日照时数呈线性减少趋势,拔节、乳熟、成熟期≥0℃积温与年份的相关系数通过了信度0.01的显著性检验;出苗、拔节、乳熟、成熟期和全发育期的日照时数与年份的相关系数通过了(P<0.01)的显著性检验。成熟期日期受成熟期间的日照时数的正相关影响(P<0.05),分蘖、乳熟期的日期受发育期间的≥0℃积温和日照时数的正相关影响(P<0.01)。造成这些差异的主要原因可能是各年的气候条件不同,其次是各年份的栽培条件、田间管理(如灌溉、施肥、病虫害防治)等非气象因子的不同所致。作物的生长及发育都是气象因子和非气象因子共同作用的结果。

Based on the meteorological observation data in Altay station during 1981-2011, it was analyzed that the change of light and heat resources for spring wheat in its full growth period, and correlation study of each of growth date and ≥0 ℃ effective accumulated temperature solar radiation hours. The results showed that the full growth period was a significant decreasing trend (P<0.01), and the test of significance showed that the effect is remarkable in tillering and milky maturity period. Results also suggested that effective accumulated temperature (≥0 ℃)during full growth period had shown obviously an linear decreasing tendency, and significant correlation between effective accumulated temperature (≥0 ℃)in jointing and mature period and year (P<0.01);there was a decreasing trend of solar radiation hours in full growth period, and it showed that correlation between year and solar radiation hours in emergence, jointing and milky maturity period. Finally, there was a positive correlation between solar radiation hours and date in milky maturity period(P<0.05), similar to ≥0 ℃ effective accumulated temperature in tillering and milky maturity (P<0.01).These differences could be mainly attributed to the different yearly climate conditions, secondly to the dissimilar non -climatic factors such as cultivate,management (irrigation, fertilization,disease and pest controlling)etc. The growth and yields in different year were formed by the joint influence both climatic and non-climatic factors.
