摘要
以超甜玉米粤甜 9号为材料 ,研究不同密度对产量及种植效益的关系。结果表明 ,适宜密度应在 4 80 0 0～ 5 4 0 0 0株 hm2 ,过高或过低都会影响鲜苞商品性状、产量及经济效益。最适宜栽培密度在 4 80 0 0株 hm2 ,此时鲜苞商品率好 ,产量和种植效益均较高。
Relation of plant density on yield and benefit in in supersweet corn YUETIAN 9 was studied.The results showed that suitable density is 48000-54000plants/hm 2.Too high or too low of density could affected co mmodity traits of fresh ear,yield and benefit.It could got good co mmodity rate,higher yield and benefit in most suitable density 48000 plants/hm 2.
