本试验结合《1996国际种子检验规程》与国内《农作物种子检验规程》(1995),采用两个规程中的低恒温烘箱法和高温烘箱法以及整粒烘干法,对目前常见的大粒农作物种子进行一系列的水分测定比较试验。从而探讨我国现行规程中水分测定方法(GB/T 3543.6—1995)的合理性,以及整粒烘干法测定种子水分的可行性。结果表明,水分测定中的烘干时间国际规程比国内规程更为合理,且在采用高温烘箱法时国内国际两个规程测得的种子水分存在差异;适于采用高温烘箱法的作物种类同样也不适于采用低恒温烘箱法;而大粒农作物种子采用整粒烘干法具有较大的可行性。
The test combined with “1996 International Seed Testing Regulations” and the domestic “Crop Seeds Inspection Regulations” (1995), using two procedures in the low constant temperature oven method and the high temperature oven method and the whole drying method, the current common big grain crop seeds A series of comparative water tests were carried out. In order to discuss the rationality of the moisture determination method (GB / T 3543.6-1995) in the current regulations of our country and the feasibility of measuring the moisture content of the seed by the whole-grain drying method. The results showed that the international rules of drying time in water determination were more reasonable than those in domestic regulations, and the differences of seed moisture between domestic and international regulations were observed when using high temperature oven method. The types of crops suitable for using high temperature oven method were also Not suitable for low temperature oven method; and large grain crop seed drying method with a greater feasibility.
