摘要
以超甜玉米粤甜3号为材料,研究不同栽培密度对其农艺性状的影响。结果表明,栽培密度在48000株/hm2时,鲜苞商品性状和产量能够得到比较好的协调,取得好的效益。密度过高或过低都会影响鲜苞商品性状、产量及经济效益。
Dynamic relation of planting density and agronomic traits in supersweet corn cultivar YUETIAN NO.3 was studied. The results showed that, the commodity traits of fresh ear could be concordant with yield, and a higher benefit was obtained in most suitable density 48000 plants/hm2. Too high or too low of density could affect the commodity traits of fresh ear, yield and benefit.
