山药栽培数学模型及优化农艺的研究

对山药综合栽培措施进行了二次旋转回归正交试验,建立了优化产量模型,根据数学中函数极大值的概念和农业经济学边际效应理论,分析了5个试验因素的关系,筛选了优化产量数学模型的山药农艺措施,并分别求出五因素中4个因素处于平均水平时,山药获取最高产量和最大经济效益(优质产品最高)的山药种块重量、种植密度和氮、磷、钾施用量。为总结山药高产、优质配套栽培、优化农艺措施提供了可靠的科学依据。

Studies on Mathematical Modes of Planting and Optimizing Agricultural Characters of Yam

Integrative planting methods of Yam have been positively tested with two times rotary regression, and the modes of optimizing output has been set up. And the relationship of five testing factors was analyzed with the conception of maximum in Math and the theory of marginal utility of agricultural economics. And the relationship between harvesting the highest output, getting the highest economical effects of Yam (high quality, highest effects) and the weight of earthnut of Yam, the density of planting and the dosage of fertilization of N, P and K was calculated with the average of four factors in five factors. Our aim is to summarize the methods of high output, high quality and optimized agricultural characters.
