降水对陇东玉米叶面积和干物质积累及产量的影响
The Impact of Precipitation to Leaf Area and Dry Matter Accumulate and Yield of Maize on Loess Plateau
【摘要】 分析降水差异对陇东黄土高原玉米叶面积和单株干物质积累及产量的影响。结果表明,在玉米生长发育期间,降水不同,叶面积增长速度不同、干物质积累速度不同、产量不同。尤其是拔节至抽雄期降水,对玉米叶面积生长、干物质积累和产量形成具有较大影响。
【Abstract】 It studied the impact of precipitation difference to leaf area and single trunk dry matter accumulated and output of maize on loess plateau in east of Gansu province.The result shown that,if the precipitation was different,leaf area increase rate was different,dry matter accumulated rate was different and the output was different during maize grow.Especially the precipitation of jointing and heading to leaf area growed,dry matter accumulate and output of maize had bigger impact.
