两种抗旱剂对玉米产量的影响研究

Effects of Two Drought-resistant Agents on Yiled of Corn

通过在干旱条件下进行玉米抗旱育苗和抗旱试验,旨在为玉米抗旱提供指导。结果表明:穗粗、穗长、行粒数、行数都比对照的高,使用抗旱剂能增加玉米的产量,只用FA抗旱龙拌种的单产最高,为789. 58kg,比对照增产8%,用旱立停拌种并喷施处理和只喷施旱立停处理下产量相差不大,分别比对照增产6. 7%和6. 4%,只喷施FA抗旱龙处理比对照增产5. 4%,旱立停拌种处理只比对照增产2. 38kg。

In order to provide guidance for maize drought resistance, maize seedlings and drought resistance experiments were carried out under drought conditions. Compared to the treatment of CK ,the drought resistance treatment not only the maize plants’ ear diameter,ear rows,plant height,ear length,grains per row,but also increased the maize yield. Using the treatment of FA ,average grain output per mu can reach 789.58kg,which increased the yield by 8%.The maize yield had incrased by 6.7%(using hanliting mixed seed and spraying),by 6.4%(using hanliting spraying only),by 5.4%(using FA), Only 2.38 kg more than control.
