天然草场生态系统中包含不同种类的牧草,不同种类的牧草有不同的生理特性。某些牧草虽然具有适口性强,营养价值较高,但是过量采食会造成动物出现不同程度的中毒,如果不能严格控制添加的或者处理不及时,易造成牲畜动物出现不同程度的中毒... 天然草场生态系统中包含不同种类的牧草,不同种类的牧草有不同的生理特性。某些牧草虽然具有适口性强,营养价值较高,但是过量采食会造成动物出现不同程度的中毒,如果不能严格控制添加的或者处理不及时,易造成牲畜动物出现不同程度的中毒,威胁严重时还会引发大量的中毒死亡,给养殖场带来巨大经济损失。在草场有毒有害杂草中包含低毒牧草和高毒牧草,低毒牧草在使用前通过妥善有效的处理,能发挥其应有的食用价值,满足牲畜的生长发育所需,具有很好的经济效益。该文主要论述几种低毒牧草的毒害特征及无害化处理和利用方式。 展开更多

In recent years, with the acceleration of urbanization, medium-sized cities face increasingly severe, fog and haze increase, the heavy air pollution concentration, which caused acute health problems such as irritation and cardiovascular diseases caused widespread concern in the community. Most scholars believe that the haze is toxic and harmful gases; particulate matter and other pollutants together lead to reduced visibility as the main manifestation of the phenomenon of air pollution. Population health effects caused by the haze have been proven in many studies. The system summarizes the polluting haze weather physicochemical characteristics, introduced widely accepted definition of haze, haze hazard to residents and the proposed requirements. 展开更多
