机场永久免维护草坪建植研究——以昆明巫家坝机场东非狼尾草草坪为例

为解决鸟害隐患,提高机场飞行安全,2004年6月,在昆明巫家坝机场草坪上选择1.5 hm2样地,分为5个试验区域建植东非狼尾草草坪;旋耕,整地,分别以株、行距均为20、40、60、80 cm的密度扦插东非狼尾草.结果表明,80 cm的行、株距是最经济的扦插密度;东非狼尾草(Pennisetum clandestinum...

Study on establishment of airport maintenance free lawn——A case study at Kunming Wujiaba airport Pennisetum clandestinum lawn

To improve the airport flight safety and remove the hidden danger of birdstrike, 1.5 ha native lawn at Kunming Wujiaba airport was used to establish Pennisetum clandestinum lawn. The native law was preparated by Disc plough and divided into 5 experimental plots, in which P. clandestinum cuttage were planted with four densities (20, 40, 60 and 80 cm row and individual plant spaces). The results showed that the most economic density was 80 cm row and individual plant space. P. clandestinum exhibited well competition with the native species at the airport. The P. clandestinum lawn became no maintenance lawn at the first established year and cost lower for continual 6 years at Kunmibg Wujiaba airport. The hidden danger of birdstrike was largely reduced because of bird food absent, lower and denser grass layer. The decibel sound through the P. clandestinum lawn was also significant reduced by 15.7% compared to the native lawn (P＜0.01). It was suggested that P. clandestinum was the top choice pasture species to establish maintenance free lawn of Kunming Wujiaba airport.
