浙江省农科院、广西壮族自治区农科院、山西省农科院、辽宁省农科院,约经一年的试验准备,于1981～1982年按照统一的试验方案,开展了谷物灰分测定方法标准化的研究工作。现将试验研究工作总结如下:一、目的意义目前,测定谷物灰分的标准方法,世界上主要有国际标准(ISO)、国际谷物化学学会标准(ICC)及苏联国家标准(ΓOCT)。我国还没有统一的标准,通过试验研究选定一种准确、快速、适合我国情况的谷物灰分测定标准方法,以便评价谷物中灰分的含量。查明土壤 Zhejiang Academy of Agricultural Sciences, Guangxi Zhuang Autonomous Region Academy of Agricultural Sciences, Shanxi Academy of Agricultural Sciences, Liaoning Provincial Academy of Agricultural Sciences, about a year of trial preparation, in 1981 to 1982 in accordance with a unified test program, the determination of cereal ash content Standardized research. The experimental work is summarized as follows: I. Significance of the Present Standard methods for determining the ash content of cereals in the world include ISO, ICC and ΓOCT. There is no unified standard in our country. Through the experimental study, we select a standard method for the determination of the grain ash content accurately and quickly, which suits the situation of our country so as to evaluate the content of the ash in the grain.
