逆境胁迫严重制约着作物的生长，植物生长延缓剂可以缓解逆境对作物生长造成的不良影响。分析了植物生长延缓剂对提高作物抗倒伏及作物在水分、温度、盐碱胁迫下抗逆性的作用，并指出对于不同的作物应当通过试验选择适宜的植物生长延缓剂种类和浓度。

The stress seriously restricts the growth of crops, and the application of plant growth retardants can alleviate the adverse effects of stress on crop growth. The effects of plant growth retardants on lodging resistance and stress resistance of crops under water， temperature and saline-alkali stress were analyzed. It was pointed out that suitable plant growth retardants should be selected through experiments for different crops.
