Abstract: A new method to prevent rice seedlings from rotting and to breed strong seedlings was examined from the point of view of chemical treatment for winter protection. The results of the study showed that soaking the seeds of early rice in ‘Yangbaoling’ solution was not only advantageous to strengthening germination potential, increasing germination rate, form good seedlings with short roots and strong sprouts, but also effective to preventing seedlings from rotting,and gaining the good early rice and increasing yield.
