两年试验结果表明，在小麦扬花期和灌浆期施用抗旱剂“植抗 ３ 号”均可明显增加小麦产量，降低干旱对小麦产量的影响。施药时期不同，增产机理不同。扬花期施药主要增加小麦的穗粒数；灌浆期施药主要增加小麦的千粒重。增产幅度在 ２０％ 左右。
The results of two years showed that applying the anti-drought agent “Zhikang 3” at the flowering and filling stages could significantly increase the wheat yield and reduce the drought impact on wheat yield. Different application period, different production mechanism. The flowering stage mainly increased the number of spikelets of wheat; the grain filling stage mainly increased the 1000-grain weight of wheat. Increase rate of about 20%.
