| 摘 要： | 田间试验结果表明,甜玉米从苗期开始,各主要生育期的物质形成累积都保持相当高的速率,但在拔节开始至抽雄、吐丝开始至成熟收获期间形成2个累积高峰。在本试验条件下,N素供应是施肥措施中对提高甜玉米物质形成累积和获取高产的主导因素。施用N肥可显著提高甜玉米的单苞鲜重和干籽率,还显著增加鲜籽粒维生素C含量。

| Abstract: | A field trial indicated that dried matter mass maintained relatively high cumulating rates from seedling through all other growth stages for the fall-sowing sweet corn,during which two cumulating peaks occurred,one from node-elongating to tasseling and the other from silking to harvesting.In conditions of this trial,N supply was the dominant factor of fertilization to increase dried matter mass and yield of sweet corn.In addition,sufficient N supply enhanced fresh ear weight,dried seed rate and vitamin C content of fresh seeds. |
