- 摘要:
- 为探讨玉米密度、茎秆强度及产量之间的关系,以敦玉27为试验材料,在15,17,19,21和23 cm,共5个株距条件下比较株距对玉米茎秆强度及产量的影响。结果表明,穗位高、百粒重、行粒数随着株距的增加而降低,短轴直径、穗长、穿刺强度、抗推力强度随着株距的增加而增加。株距对敦玉27的容重、含水量、穗行数、倒伏率影响不显著;对株高、穗位高、短轴直径、穗长、秃尖长、产量、百粒重、行粒数、穿刺强度、抗推力强度影响显著。株距为17 cm时,敦玉27的产量最高,为756.57 kg·(667 m2)-1,其最大穿刺强度和最大抗推力强度均出现在株距为23 cm处理,分别为35.82和30.81 N。
- Abstract:
- In order to investigate the relationship among density, stem strength and yield,the maize variety Dunyu 27 was used as experimental material to compare the effects of plant space on stalk strength and yield,under 5 different plant spacing conditions of 15,17,19,21 and 23 cm,respectively.The results indicated that ear height,100-kernel weight and grains per row decreased with the increase of plant spacing,while short axis diameter,panicle length,puncture strength and thrust resistance strength increased with the increase of plant space.There were no significant effect on test weight,water content, panicle row number and lodging rate of Dunyu 27 by all levels of plant space.However,plant height,spike height,short axis diameter,spike length, spike tip,yield,100-grain weight,row kernel number,puncture strength and thrust resistance strength were significantly affected.The optimal plant space was 17 cm and the piot yield of Dunyu 27 was higher than all others,which was
