摘    要:在垄作、密植2种栽培方式下,研究干旱对大豆不同品种、不同部位叶片发育的影响。结果表明:无论垄作还是密植,干旱严重影响大豆叶片不同部位叶绿素含量、叶面积及周长的大小、不同部位叶长、叶宽及比值、叶片形状因子等,影响整个植株的生长发育,进而影响作物产量。因此建议要重视干旱,提早预防。

关 键 词:干旱  大豆  叶片发育

Abstract:Under the two culture modes of ridge and dense planting,the effect of drought on leaves development of different soybean varieties and different parts was studies.The results indicated that:whether ridge or dense planting,drought severely affected chlorophyll content of different parts of soybean leaf,leaf area,the size of leaf perimeter,different parts of leaf length and width and their ratio,leaf shape factor,etc..Drought affects the entire growth and development of the plants,thereby affects the crop yield.Therefore we propose to attach importance to drought and early prevention.
Keywords:drought  soybean  the leaves development
