摘　　要：通过2011年在彰武县玉米上开展抗旱抗逆田间试验,并对不同处理对玉米生育性状、产量及纯增效益的影响进行分析。试验表明:在玉米上喷施抗旱剂,玉米株高、穗数、千粒重等都有明显提高,增产效果明显。从整体效果来看,在玉米上喷施碧护植物生长调节剂的效果要好于其他抗旱剂。In 2011 a field experiment was conducted in Zhangwu to study the effect of drought resistance. Analysis was made on the growth characteristics, yield of maize and the net profit increase under different treatments. Results show that the spraying of drought re-sistant agent in corn had produced pronounced improvement in plant height, panicle number, and grain weight, with obvious effect of in-creasing yield. Judging from the overall effect, the effect of spraying plant growth regulator Bihu on corn is better than that of other drought resistant agents.
