Whether growing grass by acrial sowing can achieve success mainil depends on the selection of suitable grass species,which is the basis of successful aerial sowing.By the research on the properties of Onobrychis viciaefolia scop and its aerialsowing effect,the experiment results show that out of a thin seed coat,the seed of Onobrychisfolia scop is so pervious to water that the germination is quick and easy its seed is resistant to hing temperature and exposure under a violent sunlight;not only its seeding takes rootsfast,strikes root dccp,but also its root system is well-developed it grows quickly,and is branchy,the natural renewal capacity stronger. Onobrychis viviuefolia scop is a promising acrial-sowing species.
