试验表明,在环青海湖地区开展临冬寄籽播种对禾本科牧草是适宜的,且生长发育状况优于春季播种。环青海湖地区退化草地补播治理项目秋季实施符合天然牧草自行演替更新的客观规律,并能克服夏季播种带来的不利影响,可以有效提高补播效果。
The experiment shows that it is appropriate to carry out seeding of seeding winter in grassland of Qinghai Lake to gramineous grass, and its growth and development is better than that of spring seeding. In the autumn, the implementation of spring back sowing and remediation projects in the Qinghai Lake area coincided with the objective law of natural succession of grazing, and overcame the adverse effects brought by sowing in summer and could effectively enhance the sowing effect.
