| 摘 要： | 以3个玉米杂交组合为试验材料,研究了3种种植密度对他们的产量和品质的影响。结果表明,贵农318、PGX-5、PGX-6玉米杂交组合之间产量差异显著,不同密度间的玉米产量存在极显著差异,供试玉米杂交组合的最佳种植密度均为6.3万株/hm2,但杂交组合与密度互作之间差异不显著。杂交组合与密度互作对玉米籽粒蛋白质含量的影响达极显著水平。不同种植密度间的淀粉含量存在显著差异,不同玉米杂交组合之间可溶性糖含量差异显著。

| Abstract: | Three maize hybrid combinations were tested under different planting density to study effects of planting density on their yield and quality.The results showed that there was significant difference in yield between three tested maize hybrid combinations;there was very significant difference in yield between different tested planting densities.The optimum planting density of tested maize hybrid combinations was 63 thousand plants/hm2 but there was no significant difference between combination and planting de... |
