以当前种草养畜这种新型绿色低碳养殖业发展模式为背景,以这种模式下普遍存在的饲草种植以产量衡量效益的唯一标准这种片面理解为切入点,建立严谨的数学模型,并以真实可信的数据为论证。最终得出具有普适性的饲草刈割期与饲草经济效益指数的线性关系函数,对于现阶段饲草种植产业的发展具有较强的实际价值和指导意义。 Taking the current development model of green grass and livestock farming as a new green low-carbon farming industry as a starting point, this unilateral understanding of forage planting as the sole criterion for measuring yield in this mode is taken as a starting point to establish a rigorous mathematical model , And to verify the true and credible data. Finally, it is concluded that the linear relationship function of universal forage grazing period and forage economic benefit index has strong practical value and guiding significance for the development of forage grafting industry at this stage.
