摘要
生物产量是提高经济产量的基础,而施肥是调控生物产量及其组分动态转化的重要手段。本研究通过不同施钾水平对玉米干物质积累动态变化的影响分析,确定出钾肥合理用量,为玉米高产高效栽培提供理论依据。
Biological production is the foundation of increasing economic production , and applying fertilizer is the important means adjusting and controlling biological production and dynamic transforming of its component. In this paper , through analysis on effect of applying potash fertilizer in different quantity levels on dynamic variation of dry matter accumulation , the authors determined reasonable applying quantity of potash fertilizer , and provided the theoretical basis for high production and high effective cultivation of maize.
