| 摘 要： | 以晋饲育1号青贮专用玉米为试验材料,研究了6个不同种植密度对其生物产量及主要农艺性状的影响。结果表明,不同密度生物产量之间差异极显著,晋饲育1号的最佳种植密度为4.95万株/hm2;种植密度对茎粗、单株鲜质量、单株干质量、单株干穗质量、绿叶数影响较大,对株高影响不大。

| Abstract: | Influence to biological yield and the main agronomic characters of Jinsiyu 1 as the test crops under 6 sowing densities was studied.The results showed that biological yield were significantly different under different sowing densities.The suitable density of the test crop was 49 500 plant/hm 2.Planting density had the greatest influence on stem diameter,single plant fresh weight,single plant dry weight,single plant dry ear weight and number of total green leaf blades,while planting density had little influence on the plant height. |
