摘要
G、H、A三种不同型号的保水剂用于小麦流体播种,并研究其应用效果。试验结果表明：3种保水剂用于小麦的流体播种,对小麦的出苗、生长发育及产量均有促进作用,可使小麦出苗提早3~5 d,平均增产24.9%,其中以H型的保水剂对小麦影响最大,增产效果最明显。由此可见,选择适宜的保水剂进行小麦流体播种,是干旱、半干旱地区适时播种保丰收的一条有效途径,值得推广应用。
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.
