| 摘 要： | 甜玉米基因抑制籽粒淀粉合成,从而影响种子发芽出苗。提高发芽率、出苗率,促进全苗,确保单位面积基本株数是获得产量的基础。综述了甜玉米种子形成、苗期生长特点,播种出苗技术要领以及浸种、拌种,种子包衣,育苗移栽,地膜覆盖,种子储藏等相关研究结果。甜玉米的采收期影响着种子质量及发芽率;低温、安全含水量对于保存种子活力十分有利,植物生长延缓剂等处理对延缓种子老化有一定效果;三十烷醇、双氧水等浸种,植物生长调节物质、种子包衣技术等处理对甜玉米种子萌发及幼苗生长有促进作用;选择好种子和土壤,掌握播种温度、深度,施足基肥是促进甜玉米壮苗早发手段;育苗移栽、覆膜栽培技术能较好弥补甜玉米播种出苗方面的先天不足。
