摘要:

气候变化加剧了作物产量变化的不确定性,通过分析找出影响内蒙古河套地区油用向日葵生产受气象条件影响的关键时段和关键气象因子,为保证内蒙古河套地区油用向日葵高产稳产提供数据支撑。本文选用内蒙古河套地区巴彦淖尔市农业气象试验站2005—2024年的油葵产量、生育期以及气象资料,利用线性回归方法从实际产量中分离出气象产量,并与油葵全生育期内各时段气象因子进行相关分析,得出内蒙古河套地区油葵生产受气象条件影响的关键时段和关键气象因子。结果表明,6月上旬(播种—出苗期),日照时数与油葵产量呈正相关;7月上旬(花序形成期),日照是影响油葵产量的主要影响因子;8月(花期和灌浆期),降水和日照是关键因子;9月上旬(成熟期),气温是关键因素。因此根据油用向日葵农业生产实际,提出气象服务重点工作建议,为河套地区油用向日葵高产、稳产提供科学依据。

Abstract:

Climate change exacerbates the uncertainty of crop yield changes. The study aims to find out the key periods and key meteorological factors affecting the production of oil sunflower, providing data support for ensuring high and stable yield of oil sunflower in Hetao area of Inner Mongolia. In this paper, the oil sunflower yield, growth period and meteorological data from 2005 to 2024 of Bayannaoer Agricultural Meteorological Experimental Station were selected. The linear regression method was used to separate the meteorological yield from the actual yield, and the correlation analysis was carried out with the meteorological factors in each period of the whole growth period of oil sunflower. The key period and key meteorological factors of oil sunflower production affected by meteorological conditions in Hetao area of Inner Mongolia were obtained. The results showed that there was a positive correlation between sunshine hours and oil sunflower yield in early June (sowing-emergence stage); in early July (inflorescence formation period), sunshine was the main factor affecting the yield of oil sunflower; in August (flowering and filling stages), precipitation and sunshine were the key factors; in early September (mature period), temperature was the key factor. Therefore, based on the agricultural production practice of oil sunflower, key suggestions for meteorological services are proposed to provide a scientific basis for high and stable yields of oil sunflower in the Hetao region.
