In order to clarify the regulatory effect of 0.01%28-high brassinolide·indole butyric acid on the growth of rice in cold regions,a randomized block design was used to study the effects of different application amounts on the growth and yield of rice in cold regions.The results showed that the application of 0.01%28-high brassinolide·indolebutyric acid granule at the tillering stage could significantly increase the tillering of rice,shorten the days from the initial heading stage to the full heading stage,promote dry matter accumulation,enhance lodging resistance,increase rice yield.When the application rate is 22.5 kg/hm2,the number of grains per panicle,seed setting rate,and thousand grain weight of rice are the highest,and the yield is the highest,making it the optimal application rate.
