高分子聚合物对沙化地储水量和玉米产量的影响
Effect of Water-soluble High-molecular Polymer on Water Capacity and Yield in Corn on Sandy Land
摘要
Abstract
In order to investigate the effect of water-soluble high-molecular polymer on water capacity and yield in maize on sandy land,we tested water capacity and yield by weighing method under different treatments. The result shows that there is higher water capacity under the treatment of adding water-soluble high-molecular polymer into sandy land at pre-sowing. There is 15 383.4 kg/hm2 yield under 225 kg/hm2 treatment,this increased 2 066.7 kg/hm2 yield than blank control,yield increasing percentage is 15.52%. There is 14 083.4 kg/hm2 yield under 120 kg/hm2 treatment,this increased 766.7 kg/hm2 yield than blank control,yield increasing percentage is 5.76%.关键词
