本文研究了四氮唑染色法测定棉籽生活力方法中影响染色和预湿速度的因素并进行了改进，使四氮喹染色测定棉籽生活力缩短到2小时，而不影响其准确性，改进方法与目前生产中常规棉籽生活力测定方法差异不显著。
In this paper, the factors that affect the speed of dyeing and pre-wetting in the method of determining the viability of cottonseed by the method of tetrazolium dyeing were studied and improved, and the viability of cottonseed by tetrazine dyeing was shortened to 2 hours without affecting its accuracy. There is no significant difference between the methods of measuring the viability of conventional cottonseeds in the current production.
