微积分理论在农业科学研究中建立数学模型的应用

Application of the Theory of Calculus in Making Mathematical Model in Agriculture

运用微积分理论 ,建立施肥与产量、高产适宜密度、稻麦分蘖增长变化、群体光合作用等数学模型。为寻求高产量最佳施肥量、最适密度以及如何掌握稻麦分蘖消长规律 ,使群体动态沿着高产轨道运行 ,保持高光效最佳群体分布 ,提供合理的分析方法和定量指标参数 。

Matheimatical models such as applying fertilicer and yield,appropriate density of high yield,change of the tillering of rice and wheat,phtosynthesis of colony were made on basis of the theory of calculus.Its aims were to seek the optimum quantity of spreading fertilizer for high yield,appropriate density and how to know about the regularity of the tillering,make the colony trends move along a high yield way,keep the optimum coliny spread,put forward reasonable way of analysis and fixed quantity pararmeters.And concluded that the theory of calculus was necessary in the scientific research of modern agriculture.
