摘要
研究探讨了高能抗旱保水剂不同使用方法、不同用量在玉米上的抗旱增产效果。结果表明,高能抗旱保水剂可以提高土壤持续抗旱能力,促进玉米的生长发育,提高玉米产量。按保水剂∶水=1∶30拌种,增产幅度最大,达16.3%。
In present experiment ,effect on droughtresistance and yield improvement under the different usage and the different quantity of highenergy droughtresistant absorbent polymer(HDAP) were studied.Its result shows the highenergy droughtresistant absorbent polymer can increase the sustained droughtresistant ability of soil ,and promote crop's growth and increase yield.When the ratio of HDAP and water is 1∶30,its increase is the biggest,up to 16.3%.
