【摘要】：甘肃拥有天然草地1564.83万hm~2,位列全国第6位。长期以来,由于受干旱、鼠虫害和超载放牧等因素影响,天然草地退化严重,并伴随大量毒草滋生和蔓延,导致大批牲畜中毒,给畜牧业带来严重经济损失。甘肃天然草地常见毒草有78科187属312种,主要毒草有:瑞香狼毒(Stellera chamaejasme)、甘肃棘豆(Oxytropis kansuensis)、黄花棘豆(O.ochrocephala)、小花棘豆(O.glabra)、变异黄芪(Astragalus variabilis)、醉马芨芨草(Achnatherum inebrians)、橐吾(Ligularia sibirica)、苦豆子(Sophora alopecuroides)、马先蒿(Pedicularis resupinata)及栎属(Quercus L.)植物等。本文结合课题组对甘肃天然草地毒草资料整理及实际调查分析,分别就近年来甘肃天然草地毒草对区域草地生态及畜牧业生产造成的毒草灾害、地理分布、毒草种类、防控对策及合理利用进行综述。
[Abstract]:Gansu has 15.6483 million hm~2, of natural grassland in the sixth place in the country. For a long time, due to drought, rodent pests and overgrazing and other factors, the natural grassland degradation is serious, and accompanied by a large number of poisonous grass breeding and spread, resulting in a large number of livestock poisoning, resulting in serious economic losses to animal husbandry. There are 78 families, 187 genus and 312 species of common poisonous herbs in natural grassland of Gansu Province. the main venomous herbs are: (Stellera chamaejasme), (Oxytropis kansuensis), (O.ochrocephala), O.glabra (O.glabra) and (Astragalus variabilis), (Astragalus membranaceus). Achnatherum splendens (Achnatherum inebrians), ligularia (Ligularia sibirica), bitter bean (Sophora alopecuroides), Artemisia equina (Pedicularis resupinata) and Quercus (Quercus L.) Plants, etc. Based on the data collation and actual investigation and analysis of natural grassland poisonous grass in Gansu Province, this paper deals with the toxic grass disasters, geographical distribution and species of poisonous grass caused by natural grassland poisonous grass in Gansu Province in recent years to regional grassland ecology and animal husbandry production. The countermeasures and rational utilization of prevention and control are reviewed.
