摘要
为了简单快速地确定一定体积的水稻种子间隙的吸水量,为浸种催芽时农药用量的确定提供依据,试验选用了中长粒型品种龙粳21和短圆粒型品种龙粳31作为研究对象,以量筒和量杯作为工具测量了一定体积的水稻种子间隙的吸水量。结果表明:长粒型的水稻品种龙粳21的种子体积与种子间隙吸水的体积之比为1∶0.437,短圆粒型的水稻品种龙粳31的种子体积与种子间隙吸水的体积之比为1:0.3956。
In order to quickly and easily identify rice seed gap water absorption of certain volume, and provide basis for determining the amount of pesticides when seed soaking to germination, long--grain variety Longjing 21 and short-round-grain variety Longjing 31 were selected as materials, rice seed gap water absorption of certain volume was measured by measuring cylinder and cup. The results showed that the ratio of seed volume of Longjing 21 to seed gap water absorption was 1：0. 437, that the ratio of seed volume of Longjing 31 to seed gap water absorption was 1：0. 395 6.
