结荚期淹水对花生农艺性状的影响

摘要

在电动防雨旱棚池栽条件下，以鲁花11号花生品种为材料，系统研究了结荚期淹水对花生农艺性状的影响。结果表明：淹水短时间抑制主、侧茎生长，之后促进节间伸长，最终使株高增加，但主、侧茎叶数减少，致叶面积系数降低；淹水减少分枝数、有效分枝数、总果针数和入土果针数。%Under electric rain drought shed ,the effects of waterlogging in pod -setting stage on the agro-nomic traits of peanut were investigated systematically .The results indicated that :in the short period within waterlogging ,the grow th of main and lateral branches was inhibited ,afterwards the node spacing was increased ,and finally the plant height was increased .But the leaf numbers of main and lateral bran-ches decreased ,which leaded to a lower leaf area index (LAI) .The total branches ,the effective branches , the total gynophores numbers and the gynophores into soil were decreased .
