农业上的各种试验,一般都需要测定种子的千粒重,以考核种子的饱满程度并据以确定下籽量。常用的方法是,每个处理数三个一千粒,分别称重,取其平均值。这样,如果处理较多的时候,不仅费工、费时间,也容易出现差错。根据优选法的基本方法,我们对胡麻千粒重的数学常数,进行了反复试验,试验结果是:以244粒胡麻种子为最优点,不论是胡麻的哪一个品种,用244粒除它的重量,然后再乘以1,000,基本符合它的实际千粒重,误差一般在±0.3克以下。这样的误差如果采 Various tests on agriculture generally require the determination of the 1000-grain weight of the seed to assess the fullness of the seed and the amount of seed under it. Commonly used method is that each treatment number three one thousand, respectively, weighed, whichever is the average. In this way, if you deal with more time, not only laborious, time-consuming, but also prone to error. According to the basic method of the preferred method, we repeated the test on the mathematical constants of 1000-grain weight of flax. The test result is that taking 244 pieces of flax seeds as the best point, no matter which type of flax seeds, 244 pieces are used for weight removal, Multiplied by 1,000, basically consistent with its actual 1000-grain weight, the error is generally less than ± 0.3 grams. Such errors if mining
