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。
Explore the early maize varieties Kenwo 2, De Meiya 2 in different fertilization factors, the yield potential of different densities. The experiment found that the growth rate of the big fat area was obviously better than that of the small fat area in different fertilizers, the fat area of the leaf area index was higher than that of the small fat area by 7.6%. The output of two varieties of different treatments: Kenwo 2 fattening area 11.8% higher than the small fat area, Demeiya 2 fattening area 12.5% more than the small fat area; different density yield 12.7%. Sprinkle with a variety of seed dressing, spraying foliar fertilizer on the prevention and treatment of residual pesticides before the stubble obvious effect, spraying Futian Jia Li, Choi Te Mei and other foliar fertilizer to increase seedling resistance.
