采用新规程检测种子发芽率 ,为使试验结果更加准确 ,笔者通过几年的工作实践谈谈应注意的问题。1　湿度1.1　砂床所用的砂子根据每次发芽的需用量 ,用大盆一次性喷水拌匀后着床 ,湿度以手握成团、一触即散为宜。防止用干砂作床 ,播种后喷水 ,这样易造成试验重复间湿度不均 ,结 Using new rules to detect seed germination rate, in order to make the test results more accurate, the author through several years of work practice to talk about should pay attention to the problem. 1 Humidity 1.1 sand bed sand used in accordance with the amount of each germination required, with a large bowl of water after a single spray, the humidity to hand into a group, touch is appropriate.
