为拓展地产牧草种子繁殖的来源,重新认识生态系统中的土壤种子库潜力,丰富天然草原植被恢复的生态措施,针对生态用种日益增长的采集、清选、播种、选育等,分析了导致品种混杂退化的各种原因,详述基因遗传原理,提出了防杂保纯的预防性方法,逐步建立生态性选育品种体系,最终实现与生态系统相适应的各类牧草种子生产基础。
In order to expand the source of forage seed propagation in real estate, re-recognize the potential of soil seed bank in ecosystem and enrich the ecological measures of vegetation restoration in natural grassland. In view of the ever-increasing collection, clearance, sowing and breeding of ecological planting, Various causes of hybrid degeneration, detailed genetic principle of genetics, prophylactic hybrid method of prevention and control, and gradually establish a system of ecological breeding varieties, and ultimately adapt to the ecosystem to adapt to a variety of forage seed production basis.
