| 摘 要： | 以4个不同熟期玉米杂交种为试验材料,在5种种植密度条件下,研究了种植密度对玉米杂交种的产量和穗部性状的影响。结果表明:产量随着种植密度的增加先增后减;秃尖长随着种植密度的增加而增加;穗长、行粒数、百粒重、单穗粒重随着密度的增加而减少。

| Abstract: | The four maize hybrid of different mature period variety were used as experiment material. The yield and ear char- acters were measured in this experiment,in which maize hybrid was planted in different planting desity conditions, analyzed the yield and ear characters. The results showed that yield increased first and then decreased with the increase of planting density. The bare top length increased , and ear length, seeds per line, hundred - grain - weight, yield per plant decreased with the increase of planting density. |
