计算面积是农业科学实验中经常遇到的一个问题。一个试验项目、一个品种、一个处理的所需面积,往往只有几平方米、几十平方米或几百平方米,折合成亩数也只是几分几厘地。但是,要说明试验结果,最终都还必须换算成亩。有的甚至一开始就要进行换算,如小区试验的播种量,开始就要折合成相当每亩下籽多少斤。这里介绍一种“加半移三”由平方米换算成亩数的简捷计算方
Calculating the area is one of the most frequently encountered problems in agricultural science experiments. A pilot project, a species, a required area for processing, often only a few square meters, dozens of square meters or hundreds of square meters, converted into acres is only a few minutes. However, to explain the test results, the final must also be converted into acres. Some even have to be converted from the beginning, such as plot seeding rate, the beginning will be equivalent to a considerable amount of seed per acre Muchuan. Here to introduce a “plus and move three” converted from square meters into acres of simple calculation
