水浮莲(Pistia stratiotes L.)用分株和种子进行繁殖。用种子繁殖,如缺乏经验则保存不易,发芽困难,生长慢。通常用种苗分株繁殖。但在华东地区,水浮莲不能在自然条件下过冬,一般都在秋末霜降前,植株大部分萎黄时,选择一部分抗寒力强、碧绿而强壮的新株,放在温室、温床 温泉或水井中保苗过冬。次年4～5月,外界气温达18℃以上时,把种苗移至室外种植。由于保苗过冬需要一定的保暖设备,保苗量小,运输不便,且要有专人看管,万一疏忽,便前功尽弃,所以春季水浮莲种苗价格昂贵,不易买到,常常延迟青饲料供应时
Pistia stratiotes L. reproduces with ramets and seeds. Breeding with seeds, such as lack of experience is not easy to save, germination difficulties, slow growth. Usually seedling ramets breeding. However, in eastern China, water lettuce can not survive the winter in the natural conditions, usually in the fall before the fall of frost, when most of the plant is chlorotic, choose a part of the cold hard, green and strong new strains, on the greenhouse, hotbed or hot spring wells Seedling winter. From April to May of the next year, when the outside temperature reaches above 18 ℃, the seedlings are moved to the outdoor planting. Due to the winter seedlings need some warm insulation equipment, seedling quantity is small, transport inconvenience, and have someone in charge, in case of negligence, they give up, so the spring water hyacinth seedlings are expensive, not easy to buy, often delay the supply of green fodder

改革开放40年，江西职业教育为经济社会发展作出了重要贡献。 党的十一届三中全会以来，我省启动了以发展中等职业教育为重点的教育结构改革的宏伟工程，一批普通中學改为职业学校或增设职业班，大部分县级“共大分校”改办成农业中学，有关厅局新办一批普通中专和技工学校，全省职业教育获得了更好的改革和发展环境。在领导体制方面，成立由副省长任组长的职业教育工作领导小组，突出政府发展职业教育的职责；在培养模式方面，
1982年，我在江西省教育厅高教处任副处长，曾到教育部高等学校干部进修班华东师范大学班学习4个月。这个班由教育部委托华东师大举办，以华东地区高校处级干部为培训对象。我们这一期是第二期，大家戏称“黄埔二期”。 一 华东师大当年拥有当时高校最大最美的校园。进修班学员被安排在第四宿舍，虽然4人一间，但都是研究生宿舍，且在研究生食堂用餐，生活方便，环境安静。学校为进修班配备了很强的师资力量和管理团队。
