摘要
能源牧草抗逆性强、产量高,既能提供优良饲料,又能生产生物能源,兼有经济效益和生态效益,在盐碱地生态治理和生态产业发展中,开发潜力巨大。文章分析了甜高粱、柳枝稷、巨菌草和苜蓿等几种典型能源牧草的特性,从盐碱地耐盐植物筛选利用、微生物生态治理以及生态治理装备和技术等方面总结了盐碱地生态治理关键技术的发展趋势,分析了盐碱地生态治理的困境,并提出了以能源牧草为核心的盐碱地生态治理模式,为盐碱地生态治理和生态产业提供了新的发展思路。
Energy forage can be used for animal feed and bio-energy feedstock,and has both economic and ecological benefits.It has great exploitation potentialities in ecological management and eco-industrial development of saline-alkali land,because of high productivity and strong stress resistance.In this paper,characteristics of several typical energy forages such as sweet sorghum,switchgrass,Pennisetum sp.and alfalfa were introduced.Ecological management techniques of saline-alkali land including halophytes screen and application,microbial treatment,agricultural equipment technology were summarized,and dilemma of saline-alkali land ecological management was analyzed.In addition,a new saline-alkali land ecological management model using energy forage was put forward,which proposed a new idea for ecological management and eco-industrial development of saline-alkali land.
