碱茅草改良盐碱地适应区域试验是“七五”期间农业部重点课题之一。农业部畜牧兽医司会同科技司于6月26日至30日,在新疆组织了全国有名望的专家,就此课题进行了验收签定。该项目是由吉林农科院畜牧分院牵头主持,有新疆农垦科学院水土所,甘肃草原生态研究所,中国农科院草原所,内蒙古畜牧科学院,吉林省大安市草原工作站,长白山资源研究所等七个参加单位,共同承担对碱茅草改良硫酸盐土,氯化物盐土和苏打盐土为主的,次重盐渍化重盐碱地适应性区域试验。通过五年的试验结果表明:在灌溉条件下0～30公分土层含盐量适应范围,以硫酸盐为主的盐渍土含
Alkali grass improvement saline-alkali land to adapt to the regional experiment is “seven five” during the Ministry of Agriculture one of the key issues. The Animal Husbandry and Veterinary Department of the Ministry of Agriculture, together with the Science and Technology Department, organized a nationwide reputable expert in Xinjiang from June 26 to June 30 to sign the acceptance on this issue.
