我们根据多年来水稻高产栽培指标化、数量化、仪器化的研究实践,以及光照、苗情、土肥与水稻产量形成的复杂关系,建立能够囊括水稻生理、生态、个体、群体主要特征,求算肥料施用种类与数量的数字模型。经过数学处理,编成计算程序,输入微型电子计算器中,并固定下来,从而研制成既具备有专用稻作计肥、配肥功能,又有普通计算功能的新型电子计算器,简称“稻作配肥电算器”,为农民进行水稻耕作提供了可靠的计肥工具。“稻作配肥电算器”只要按顺序输入5个与生育有关的因素变量,就能显示6种计算功能,现作简要说明。(一)5个因素1.品种,分早、中、迟熟3种类型,每类标记代号并输入电算器。
According to the years of high yielding cultivation of rice indicators, quantitative and instrumental research practices, as well as light, seedlings, soil fertility and the formation of the complex relationship between rice yield, to establish can cover the main physiological characteristics of rice, ecology, individuals, groups, calculated A numerical model of fertilizer application types and quantities. After mathematical processing, compiled into a calculation program, enter the micro-electronic calculator, and fixed, so as to develop into both have dedicated rice for fertilizer, fat function, there are ordinary computing functions of new electronic calculators, referred to as “rice As fertilizer calculator ”for farmers to provide a reliable rice paddy fertilizer tools. “Paddy fertilizer calculator” as long as the order of five variables and fertility-related variables, you can display six kinds of computing functions, are briefly described. (A) five factors 1. Varieties, points early, middle and late maturity 3 types, each type of code and enter the calculator.
