根据调查,近几年来,我省在壮丰灵的应用中,普遍存在喷施期偏晚的问题,未能更好地发挥其增产作用。就这个问题,我们从1995年以来做过多次喷期试验,分别为6月25日、6月30日、7月5日、7月10日、7月15日、7月20日和不喷共7个处理。试验结果如下: 1、株型结构变化壮丰灵是促控结合的植物生长调节剂,不同喷施期对植株高度影响不同。喷施期过早(6月25日、6月30日)或过晚(7月20日)对植株矮化效果均不够理想。矮化效果最好的喷施期为7月10日,株高228.7厘米,其次是7月5日和7月
According to the investigation, in recent years, the application of Zhuangfengling in our province has the problem of late spraying period generally, and fails to exert its increasing production effect better. On this issue, we have done a lot of spraying test since 1995 on June 25, June 30, July 5, July 10, July 15, July 20 and not Spray a total of seven treatment. Test results are as follows: 1, the plant structure changes Zhuangling Ling is a combination of promoting plant growth regulator, different spraying period on the height of different plants. Spraying too early (June 25, June 30) or too late (July 20) are not ideal for plant dwarfing. Dwarfing effect of the best spraying period is July 10, 228.7 cm tall, followed by July 5 and July
