摘要
研究不同用量保水剂在玉米上的抗旱增产效果及保水剂对旱地玉米产量性状及产量的影响。结果表明,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。以每公顷穴施30 kg进口保水剂增产幅度最大,达13.6%。
This paper studied the effect on dry land maize drought-resistance and yield improvement under the different dosage of absorbent polymer;the result showed that,the absorbent polymer could increase the lasting drought-resistant ability of soil,promote maize growth and increase the yield.When hole application was 30 kg/acres,the yield increasing scale would be the biggest,up to 13.6%.
