| 摘 要： | 以高油玉米298为材料,研究了密度对高油298产量和含油率的影响.结果表明:密度对高油298的产量和含油率有显著影响,随密度增加,高油298的穗粒数、百粒重、子粒的含油率降低;吐丝期光合速率随密度增加而下降;成熟期粒叶比随密度增加而减小;子粒产量均在一定范围内先升后降.在本试验条件下,获得最高子粒产量的密度为60 000株/hm2,产量为7 472.4 kg/hm2,子粒含油率为9.84%,综合考虑子粒产量和含油率二因素,密度为60 000株/hm2时油产量最高,为643.2 kg/hm2。

| Abstract: | Effect of plant density on yield and grain oil content in high oil corn 298 was studied.The results showed that kernels of per car,the weight of hundred kernels,grain oil content,photosynthetic rate in silking,and kernel/leaf ratio in maturity was decreased with the increasing of plant density.Yield was increased and then decreased with the increasing of plant density.The highest yield was 7472.4 ks/ha and oil yield was 643.42 ks/ha under plant density of 60000 plants/ha spectively. |
