| The application effects of three water-retaining agents(G,H,and A) in fluid seeding of wheat were investigated in this experiment.The results demonstrated that the three water-retaining agents in fluid seeding were all stimulative in the germination rate,upgrowth and yield of wheat.The germination date was 3～5 days earlier than that of routine seeding,and the yield of wheat in fluid seeding was averagely increased by 24.9%.Among three water-retaining agents,the application effect of H in fluid seeding was the most obvious.This showed that fluid seeding with fitting water-retaining agent was an effective approach to the timely seeding and insuring a bumper harvest for the arid and semiarid region,and it is worth popularizing and applying in agricultural production. |
