Analysis of flying-catkin inhibition effect of different chemicals on Bombax ceiba
摘要
Abstract
[Objective]Bombax ceiba is widely used in landscaping in South China,but its flying-catkin in fruit period can cause respiratory diseases,traffic accidents and various other problems.Effective management of flying-catkin has become an urgent demand of the public in many parts of South China in recent years,and also a thorny problem for the landscaping department.[Method]In this study,we used perennial Bombax ceiba in Fuzhou city as the test material,and applied different concentrations of Xubizhi,ethephon,calcium formate and TMN-6 at different stages of Bombax ceiba flowering in the form of injections and sprays,and then counted the flowering situation and the fruiting rate of the trees to analyze the flying-catkin inhibition effect of the above agents on Bombax ceiba.[Result]The results showed that in the injection test,one bottle of Xubizhi injection on 5 cm and 10 cm of breast diameter before the flower bud differentiation stage of Bombax ceiba could inhibit the production of flying-catkin by preventing the flowering and fruiting of Bombax ceiba trees in the following year.In the spraying test,spraying 8 g/L of ethephon at the peak and final flowering stage could reduce the fruiting rate of Bombax ceiba by 100％,but resulted in thinning of leaf.Spraying 4 g/L of ethephon at the peak and final flowering stage could reduce the fruiting rate of Bombax ceiba by 97.48％and 98.80％,respectively,with good thinning effect;spraying 40 g/L of calcium formate and 1.5 mg/L of TMN-6 at the peak flowering stage could reduce the fruiting rate of Bombax ceiba by 95.39％and 97.69％,respectively;the thinning effect of TMN-6 and calcium formate at each concentration at the final flowering stage was significantly reduced,which could not meet the needs of production applications.[Conclusion]Combined with the cost analysis,the injection of one bottle of Xubizhi on 10 cm diameter before the flower bud differentiation stage of Bombax ceiba or the spraying of 4 g/L of ethephon at the final flowering stage could have a good thinning effect,and the cost is relatively low,which has a good prospect of popularization and application.关键词
