【 摘 要 】

The decrease in the rice yield caused by salty winds is due to the increased amount of sodium (Na) adhered to panicles and leaves. The effect of the amount of Na adhered to plants on the yield of rice has been studied, but not the relationship between the amount of salt adhered to the panicles and yield or quality of rice. In this study, we determined the relationship between the amount of seawater of salt water sprayed to panicles and that of Na adhered to rice panicles, and examined the effect of the artificial spraying on the degree of damage, yield and quality of grains in comparison with the salt wind damage caused by typhoon No. 15 in 2004. The amount of Na adhered to panicles was closely related to the amount of seawater sprayed. The relationship between the amount of Na adhered to panicles and the decrease in yield and whole grain percentage after artificial spraying was similar to that after the typhoon. Thus, artificial spraying of seawater may be used to analyze the salt wind damage caused by the typhoon.
