摘  要：
为了探索提高谷子产量、改善谷子品质的途径,以12个谷子品种为材料,设置施肥与不施肥2种处理,研究施肥对谷子农艺性状、产量以及抗倒伏能力的影响。结果表明,12个谷子品种在施肥处理下的株高、穗长、穗粗、单穗质量和产量均高于不施肥处理。不同谷子品种的顶3叶叶面积、叶绿素含量、茎秆弯曲应力和倒4节间折断指数受施肥影响表现各异,但总体上,施肥处理谷子顶3叶叶面积、叶绿素含量高于不施肥处理;施肥处理茎秆弯曲应力低于不施肥处理,倒4节间折断指数高于不施肥处理,即施肥处理谷子抗倒伏能力差。

摘  要：
In order to explore the way for increasing the gain yield and improving the quality of foxtail millet[Setaria italica(L.)Beauv.],a fertilization experiment was conducted using 12 millet varieties to elucidate the effect of fertilization on agronomic traits,grain yield and lodging resistant ability.The results showed that plant height,panicle length,panicle diameter,single panicle weight and yield of all millet varieties were higher in fertilization treatment than that in none-fertilization treatment.The effects of fertilization on leaf area of top three leaves,chlorophyll content,stem bending stress and break index of the fourth internode from the top were variable among different millet varieties.In general,the leaf area of top three leaves and chlorophyll content of foxtail millet were higher in fertilization treatment than that in none-fertilization treatment,while the stem bending stress was lower in fertilization treatment than that in nonefertilization treatment,and the break index of the fourth internode from the top was higher in fertilization treatment than that in none-fertilization treatment,suggesting that the lodging resistant ability of foxtail millet became worse in fertilization treatment.
