摘要
飞播种草能否获得成功,主要取决于草种选择是否适宜,选择适宜的飞播草种,是飞播种草成功的基础。该文对红豆草的特性及飞播效果进行了试验研究,结果表明:红豆草种皮薄、透水性好、吸水萌发快、易发芽,种子抗高温和曝晒,幼苗生很快、扎根深、根系发达,生长发育快、分枝多,具有较强的天然更新能力,是一种很有发展前途的飞播草种。
Whether growing grass by aerial sowing can achieve success mainly depends on the selection of suitable grassspecies,which is the basis of successful aerial sowing. By the research on the properties of Onobrychis viciaefolia scopand its aerialsowing effect, the experimental results show that out of a thin seed coat, the seed of Onobrychis viciaefoliascop is so pervious to water that the germination is quick and easy; its seed is resistant to hihg temperature and expo-sure under a violent sunlight ; not only its seedling takes rootsfast,strikes root deep,but also its root system is well -developed ; it grows quickly, and is branchy, the natural renewal capacity stronger. Onobrychis viciaefolia scop is apromising aerial - sowing species.
