摘要
通过对气吹式精密播种机田间试验资料的相关分析，发现合格指数Ａ与｜Ｄ－Ｍ｜（重播指数与漏播指数之差的绝对值）之间里极显著负相关（ｒ＝－０．９３１２）。在对数据作进一步回归分析的基础上，本文建立了一套“由排种粒数预测排种质量”的方法。
Correlation analysis is used to deal with the data of field experiment of pneumatic single seed drills. It is found that quality of feed index A is very significantly correlatel with |D-M| (i. e. absolute value of difference of multiples index D and miss index M). On the basis of regression analysis, a method is advanced which can estimate quality of feed according to amount of seed distributed.
