| 摘 要： | 为了解不同播种期对不同玉米品种农艺性状和生物产量的影响,以及生物产量与品种、播种期及农艺性状之间的相关性,试验选用了6个玉米品种和4个播种期来研究不同播种期对玉米品种农艺性状与生物产量之间的关系,其中,所选品种中青贮专用型、粮饲兼用型各3个。结果表明,青贮玉米的农艺性状在不同品种与播种期之间表现出组内的显著性差异(P<0.05),但组内个别播种期或品种之间差异不显著(P>0.05);构成玉米生物产量的组成因子依次为刈割全株重、刈割秸秆重、绿叶数量、穗位、株高和果穗重,而品种与生物产量呈现出显著负相关。鄂西南低山平原适合种植的青贮专用型品种为雅玉青贮8号,适宜在4月下旬播种;蠡玉16在不同播种期下对生物产量的影响较大,播种期提前时生物产量相对较高,作为粮饲兼用型品种具有一定的推广应用价值。

| Abstract: | This study aimed to assess the effects of different sowing dates on agronomic and biological yield of different maize varieties and to evaluate the correlation among biological yield and varieties,sowing dates and agronomic traits.Six maize varieties and four sowing dates were set to investigate the relationship between agronomic traits and biomass yield of varied maize varieties in different sowing dates.Among the selected varieties,three were silage-specific type and the others were dual-purpose(grain/feed)type.The results suggested that the agronomic traits of silage maize showed significant differences among different varieties and sowing dates(P<0.05),but there was no significant difference among individual sowing date or variety(P>0.05);the components of maize biomass yield were cutting plant weight,cutting straw weight,number of green leaves,ear position,plant height and ear weight,while there was a significant negative correlation between varieties and biomass yield.Yayu Silage No.8 was a suitable variety for planting in the low mountain plain region in southwest of Hubei Province and was recommended to be sowed in the late April.For the variety of Liyu 16,a great influence of different sowing dates on biological yield was observed:an advance in sowing date largely improved the biological yield,indicating that this variety had a certain application and promotion value as a dual-purpose maize variety of grain and feed. |
