摘　　要：株距的均匀一致性以及调节水平是衡量精密播种的3个指标之一。目前各种精密播种机在播种量上存在的问题是变化少,调节能力差,不能满足密度设计的需要。变径地轮的发明,使原来播种量等级增大50倍以上,株距调节水平为1mm;还可按1%水平发芽率亏损补偿调节播种量。变径地轮是精密播种机株距的无级调节器,是不同地区不同作物播种量的通用调节器。The heterosis utilization has been an important way to breed new varieties of high yield, fine quality, early maturity and multi-resistance. There are many factors affecting the purity of hybrid, so it is difficult to control the quality. The lack of rapid and economical method to test the purity of hybrid, greatly limits the speed of promotion of hybrid breeding, and increases the risk of business hybrid. The GFP protein,which can be derived from marine organisms, as reporter gene,has the advantages of accurate, simple,rapid and economical in cotton hybrid purity test.
