扔掉自缚的绳索有人说,共产党领导中国革命,先是由南而北,后是由北而南。前者是指红军长征,纵横大半个中国,沿路“播种”,然后落脚陕北;后者指解放军分路南下,解放中南、西南、华东以至全国。1948年底北平解放,革命全局可以说奠定了。南下!南下!解放江南半壁,完成全国解放大业!各阶层人民特别是青年学生中,涌起“老北京”们从未见过的革命大潮。
Someone says that the communist party led the Chinese revolution first from south to north, then from north to south. The former refers to the Long March of the Red Army. As many as half of China, it sowed along the roads and settled in northern Shaanxi. The latter refers to the People’s Liberation Army that detached itself from the south and liberated Central South, Southwest, East China and the whole country. The liberation of Peiping in 1948, the overall situation of the revolution can be laid. Go south! Liberate the south half of the river and complete the great cause of national liberation! Among the people of all walks of life, especially young students, the revolutionary tide that “Old Beijing” have never seen before.

甘蓝型油菜(BrassicanapusL)是我国很重要的经济作物之一,虽然中国是最大的油菜生产国,但是在提高油菜产量上仍然面临着很多问题和挑战。长江中下游地区是我国种植油菜的主要产地,由于恶劣环境的影响,该地区经常会发生季节性干旱甚至冻害等自然灾害,造成油菜大面积的减产,因此培育高抗逆的油菜品种,是提高我国油菜产量的一个重要途径,挖掘油菜逆境应答基因,尤其是可以同时应答几种不同逆境胁迫的基因,了解
水稻的许多重要农艺性状如株高、抽穗期等都是表现连续变异的数量性状,它们的性状表现受遗传多基因控制,而且和环境存在一定的互作,控制这些数量性状的基因成为数量性状基因(或基因座)(Quantitative Trait Locus, QTL )。QTL 研究对改善作物农艺性状、提高作物产量有重要的意义。本研究用两个籼稻品种中156 和谷梅2 号杂交,构建了由304个重组自交系(Recombinant I
