沈玉18号是沈阳市农业科学院玉米研究所选育的优质玉米杂交种。为了探索沈玉18号的适宜栽培模式,2005年在沈阳市农业科学院试验田进行了不同肥力条件下的不同密度的试验。结果表明:在低肥条件下(纯N 75 kg/hm2),密度39 000~46 500株/hm2能获得较高产量,9 041.6~9 548.7 kg/hm2。
Shen Yu No. 18 is Shenyang Academy of Agricultural Sciences corn Institute selected high-quality corn hybrids. In order to explore the suitable cultivation mode of Shenyu 18, different density experiments under different fertility conditions were conducted in the experimental field of Shenyang Academy of Agricultural Sciences in 2005. The results showed that under the condition of low fertilizer (pure N 75 kg / hm2), the yield of 39 000 ~ 46 500 plants / hm2 was higher than that of 9 041.6 ~ 9 548.7 kg / hm2.
