　　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 quali-ty.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 re-porter gene,has the advantages of accurate , simple,rapid and economical in cotton hybrid purity test .
