摘要
研究不同种植密度对鲁糯6号玉米产量性状及品质的影响,结果表明:随着种植密度的增加,穗长、穗粗、穗粒数下降,秃尖增加,鲜穗产量和商品穗数均呈先增后降的趋势,6.0万株/hm2时鲜穗产量最高,达到20 022.0 kg/hm2;随着种植密度的增大,各密度间蛋白含量变化不明显,油分含量呈下降的趋势,淀粉含量变化无明显规律。鲁糯6号最佳种植密度为5.25万～6.00万株/hm2。
The effects of planting density on yield and quality of waxy corn Lunuo 6 were studied.With the density increasing,the ear length,ear diameter and grain number per spike decreased,bald tip increased,fresh ear yield and commodity panicle number first increased and then decreased,the highest yeild of wary corn was 20 022.0 kg/hm2 with the planting density of 60 thousand per hectares.With the increase of planting density,the protein content among different density did not change significantly,oil content decreased,starch content changed irregularly.The Adopting density of Lunuo 6 was between 52.5 thousand and 60.0 thousand per hertares gained the highest yield and good quality in the experiment.
