水分是种子细胞内部新陈代谢的介质,正确的测定种子水分,不但是为合理确定收购价格提供必不可少的依据,而且对种子贮藏亦十分有利.因此,在种子收购过程中,测定种子水分是极为重要的工作,特别是在入库前的水分测定尤为重要。棉花种子水分测定时,规定一粒种子必需切12片,实际工作中我们发现这种方法费时费工,且劳动强度很大,是测定人员的一大难关;给棉种收购、入库工作带来一定困难;并在人力、物力(电、烘箱等)的有效利用上也不经济。上海市种子公司曾提出可否用“粉碎法”测定棉花种子水分,为此我们对这一方法进行了研究。
Moisture is a metabolic medium inside seed cells, and the correct determination of seed moisture not only provides an indispensable basis for determining the purchase price reasonably, but also is very beneficial for seed storage Therefore, in the process of seed acquisition, determination of seed moisture is extremely Important work, especially before entering the moisture measurement is particularly important. Cotton seed moisture determination, the provisions of a seed must be cut 12, the actual work we found that this method takes time and labor, and labor-intensive, is a measure of personnel a major difficulty; to the cotton seed acquisition, storage work with the band It is not economical to make effective use of manpower and material resources (electricity, ovens, etc.). Shanghai Seed Company had put forward the possibility of using the “crushing method” to determine the moisture content of cotton seeds. To this end, we conducted a study on this method.
