摘要
飞播种草是沙化、退化草地治理的重要技术措施之一,近10年在财政部、农业部的大力支持下,全国开展了以"飞播种草+保护利用"为核心,对牧草筛选、草种组合、种子处理、地面处理、适时播种、机型选择、播后管护、合理利用8项关键技术进行组装和研究,集成应用在北方沙化退化草地区等6个不同生态区域中。在筛选以乡土草种为主的飞播草种、最佳播种时期、青藏高海拔利用直升机播种等方面实现了自主创新。在豆科草种接种根瘤菌与混合草种拌种增产菌、应用GPS导航技术、地面处理、组织管理等方面实现了集成创新。为改善草原生态环境、饲草饲料资源开发和保护生物多样性奠定了一定的基础。
Forage aviating seeding is one of important measures in desertification and deterioration control of grassland. Under the auspices of MOF and MOA in the last ten years, an integrated technical study on forage species selection, variety combination, seed treatment, land surface treatment, proper seeding time, airplane type selection, maintenance after seeding and reasonable utilization was conducted in the county, focused on aviating seeding and protection and utilization. An independent innovation was achieved in terms of local species orientated forage selection, optimal seeding time, as well as using helicopter for high altitude area of Qinghai-Tibet Plateau. Combined innovation was also realized in legume inoculation, GPS navigation, land surface treatment and organization and management. These innovations formed a basis for grassland ecological environment improvement, feed resource development and biodiversity protection.
