棉花考种是一项作业量大而细致的工作,基层单位的技术员计算单株、株行、株系的衣分需用很多时间,且易发生错误。后来《农业科技通讯》介绍了衣分秤,用它可以避免繁琐的计算.但由于轧花过程中棉籽往往容易失落而不被注意,以皮棉重和棉籽重相对关系为依据的衣分秤,往往测不准衣分(偏高)。而且不称籽棉重,又不知单株产量,在实际考种时要衣分秤,还得要天平。现在我们设计“棉花考种衣分计算图”,不必增添别的工具,只需简单的计算图和直尺(见图)就行,且计算速度快,精确度符合考种要求,不易发生误差,又 Cotton test species is a large and meticulous work workload, the grassroots units of technicians to calculate single plant, plant lines, strains of clothing points require a lot of time, and prone to error. Later, “Agricultural Science and Technology Newsletter” introduced clothing points scale, use it to avoid cumbersome calculations.But due to cottonseed process is often easy to lose and not be noticed, in order to lint weight and cottonseed weight relative relationship based on the clothing points scale, Often undetectable clothing points (high). And do not say seed cotton weight, but also do not know the yield per plant, in the actual test when the test points to scale, have to balance. Now we design “cotton test clothing points calculation diagram”, without adding other tools, simply calculate the graph and ruler (see Figure) on the line, and the calculation speed, accuracy in line with test requirements, not prone to error, also
