Taking jujube trees aged from 14 to 16 as experimental materials, the effects of spraying different kinds of triacontanyl alcohol on different dates, different concentrations, different times and varieties were carried out in Xizai Temple, Xiaochuangzhuang and Nantian Village in Zaoyuan from 1983 to 1984. Test. The results are as follows: 1. Effect of triacontanol sprayed on fruit set rate of jujube at different florescence: The effect of spraying triacontanol at the flowering of 30-50% (spraying 0.7ppm triacontanol) was the most obvious. Compared with the control,
