摘要
为了解不同气象因子对木薯淀粉含量的影响,并给木薯种植规划和栽培提供理论依据及技术支持,以GR3为材料,对3年4个试验点的木薯淀粉含量与8类气象因子的关系进行分析。结果表明:淀粉含量与年均温达到极显著正相关,与年积温、9月份均温达到显著正相关,与10月份月均温、11月份月均温、3月份月均温和年日照呈正相关,与降水量呈负相关;年均温、10月份月均温和11月份均温是影响木薯淀粉含量的主要气象因子。结论:提高各种温度因子、增加日照时数、减少降水量有利于淀粉积累;以年均温为主要参考指标,结合10月份均温和11月份均温规划种植木薯,可保证木薯淀粉含量。
For exploring the meteorological factors that affects the cassava starch content,and provide a scientific basis for cassava planting and cultivation,taking GR3 as the material,the relationship of cassava starch content in four sites in the three years with eight meteorological factors was analyzed. Results： Starch content very significantly positively correlated with annual mean temperature,significantly positively correlated with annual accumulated temperature and mean temperature in September,positively correlated with mean temperature in October,November,March and annual sunshine,and negatively correlated with precipitation; Annual mean temperature,mean temperature in October and November were the main meteorological factors affecting cassava starch content. Conclusion： Improving various temperature factors,increasing sunshine time and reducing rainfall were beneficial for starch accumulation. To ensure cassava starch content,it was essential to take annual mean temperature as the major reference index and plant cassava combined with the mean temperature in October and November.
