Chlormequat Chloride and silicon fertilizer combination helps southern China's rice resist typhoons and increase yield by 15%

As the typhoon season approaches, the Guangdong Provincial Agricultural Technology Extension Center has issued the "Comprehensive Technical Guide for Stress Resistance and Yield Increase", recommending the "Chlormequat Chloride-Silicon Fertilizer Synergistic Program" for the first time. In the demonstration field of Leizhou Peninsula in Zhanjiang, Chlormequat Chloride (height control and lodging prevention) was sprayed during the rice heading period, combined with foliar silicon fertilizer (to strengthen the cell wall), which increased the bending resistance of the stem base by 2.3 times.

"After the passage of Typhoon Haikui, the lodging area in the treatment area was only 5%, while that in the control area reached 62%." The technical specialist introduced that the program also promoted the transfer of nutrients to grains, increased the thousand-grain weight by 8.3%, and exceeded 650 kilograms per mu. At present, 230,000 acre of rice has been promoted in the southern China rice area, saving farmers more than 10 million yuan in losses.
