伟大领袖毛主席教导我们:“对情况和问题一定要注意到它们的数量方面,要有基本的数量分析”。几年来在农村基点接受贫下中农再教育、学习科学种麦过程中,感到广大农村科技队伍迫切需要简易的田间调查和数据运算的方法,以掌握作物群体和个体数量性状上的动态变化,从中总结高产栽培的规律。我在学习“亩数与平方米”的换算法后,受到启发,在实践中推导出一些口诀、经验公式,进行某些数据的速算。这些方法运算方便,多数用“心算”就能得出可靠的数据,容易掌握。现将有关小麦部分介绍如下:
Chairman Mao, the great leader, taught us: “There must be a basic quantitative analysis of the number of situations and issues that must be noted.” Over the past few years in the rural areas to accept low-income middle peasants reeducation, study of scientific wheat growing process, I feel the vast number of rural scientific and technological teams in urgent need of field investigation and data computing methods to grasp the crop population and individual quantitative traits in the dynamic change, from which to summarize High-yielding cultivation law. After studying the conversion method of “mu and square meter”, I was inspired to deduce some formulas and empirical formulas in practice and make some calculations of the speed of some data. Convenient operation of these methods, the majority of “mental arithmetic” will be able to come to reliable data, easy to grasp. Now the wheat part of the introduction are as follows:
