| 摘 要： | 为寻求青贮玉米最佳种植密度,以青贮玉米高油106为试材,在6.0万、6.5万、7.0万、7.5万和8.0万株.hm-2种植密度下,研究了密度对青贮玉米高油106生物产量及品质的影响。结果表明:高油106的生物产量随着种植密度的增加先增后减,密度在6.5万株.hm-2时,产量达到最高22 980kg.hm-2。在一定的密度范围内,随着种植密度的增加,高油106全株粗蛋白质、粗脂肪含量表现为逐渐下降的趋势,粗纤维含量表现为逐渐上升的趋势。

| Abstract: | In order to seek the best planting density of silage maize,the effects of different densities on yield and quality of silage maize Gaoyou106 were studied under 60 000,65 000,70 000,75 000,80 000 plants·hm-2.The results showed that the yield increased first and then decreased with the increasing of the plant density.The yield reached maxmum 22 980 kg·hm-2 in 65 000 plants·hm-2.Within certain density range,crude protein and crude fat content were decrease,crude fiber was increased with densities increasing. |
