测定种籽饱满充实度,一般均用种籽的千粒重或容重来表示。但在实际工作中,这两种办法不仅受着条件的限制,同时往往因栽培地区与栽培技术的不同以及种籽含水量的不同,就直接影响其种籽饱满与充实度的准确性。同时测定千粒重或容重(千粒重用天平,容重用容重器)所需的时间也较多。最近, Determination of seed full degree of fullness, are generally used seed weight or grain weight to represent. However, in practical work, these two methods are not only limited by the conditions, but also often depend on the cultivation area and the different cultivation techniques and the difference of the seed moisture content, which directly affects the accuracy of seed fullness and abundance. Simultaneous determination of 1000-grain weight or bulk density (1000-grain reusable balance, bulk density with heavy equipment) also takes more time. recent,
