早熟玉米高密度不同施肥量栽培试验

Cultivation Experiment on High-density and Different Fertilization of Precocious Corn

探索早熟玉米品种垦沃2号、德美亚2号在不同施肥因素、不同密度的产量潜力。试验发现,不同施肥量,大肥区的长势明显好于小肥区,叶面积指数大肥区高于小肥区7.6%。两个品种不同处理产量:垦沃2号大肥区比小肥区增产11.4%,德美亚2号大肥区比小肥区增产12.5%;不同密度产量增产12.7%。用碧护拌种、喷施叶面肥对防除前茬大豆残留药害效果明显,喷施福田佳利、彩特美等叶面肥有增加苗期抗逆性的功效。

Yield potential of precocious corn Kenwo 2 and Demeiya 2 under different fertilization factors and different density was explored. Tests found that growth in big fat area was obviously better than small area,leaf area index was higher 7. 6% in big fat area than small area under different fertilization. The yield with different treatments of two varieties： Kenwo 2 increased production 11. 4% in big fat area than small area,Demeiya 2 increased production 12. 5% in big fat area than small area,production increased 12. 7% under different density. Effect of controlling residual injury of previous soybean was obvious using Bihu seed dressing and spraying leaf fertilizer. It had effect of increasing seedling resistance according to spraying leaf fertilizer of Futian Jiali and Caitemei.
