教书之余,尚有一丝闲暇,无意间摊开一家省报的历年合订本浏览,发现有两条新闻的标题几乎相同,内容大体一样。但是,时间间隔长达7年又8个月,油然使人感到莫名其妙。这两条新闻发表在同一家报纸上。一条登在1976年11月9日第一版,标题为《我省景泰川电灌二期工程开工》。主要内容是: 我省大型电力提灌工程景泰川电力提灌二期工程,最近开工了。开工的这一天,来自景泰、古浪灌区的民
Apart from teaching, there is still a little leisure time, inadvertently spread over a calendar of the provincial newspapers to read the book and found that there are two news headlines are almost the same, the content is generally the same. However, the time interval of up to seven years and eight months, people feel puzzled. The two news articles are published in the same newspaper. An article published in the first edition of November 9, 1976, titled “The Second Phase of Jingtai Chuan Electric Irrigation Project in Our Province” started. The main content is: large-scale power irrigation project in our province Jingtai Electric Power irrigation project two, recently started. The day started, people from Jingtai, Gulang Irrigation District

水稻作为我国重要的粮食作物之一，其安全生产的重要性是毋庸置疑的。然而，随着淡水资源缺乏、全球工业化，土壤盐化面积随之增加。土壤盐化是阻碍水稻安全生产和安全发展的关键非生物胁迫条件，由此看来，开展水稻的耐盐性研究具有重要意义。本研究利用长白10与东农425杂交所获得的F_(2:3)群体为试验材料，进行遗传连锁图谱的绘制，在盐胁迫和对照条件下对水稻孕穗期的叶片性状、稻株Na~+、K~+含量和最终产量性

水稻是世界上最重要的粮食作物之一,全球一半以上的人口以稻米为主食。随着社会的不断发展,人们对于水稻的产量和稻米的品质提出了越来越多的要求,提高水稻的单产并改善稻米的品质成为水稻育种家最为主要的育种目标。非洲栽培稻种质资源中广泛存在着各类抗病虫、耐盐碱、抗旱、耐高温等相关性状的优良基因,而且亚洲栽培稻与非洲栽培稻之间具有强大的种间杂种优势,若能将非洲栽培稻中的优良基因引入到亚洲栽培稻中,并很好的利用
