Effects of Soaking Seeds with Different Solutions on the Growth and Yield of Rice

In this study,Rongyou463 seeds were used as experimental materials and soaked with different solvents （conventional agent, ＂Yonghao＂ soaking liquid, and water） to investigate the effects of ＂Yonghao＂ soaking liquid on biological characters and yield of rice. The results showed that using ＂Yonghao＂ soaking liquid can significantly improve the seedling quality and yield of rice, which mainly expressed in the increase of effective panicle number, seed setting rate and 1 000-grain weight.
