摘    要:池栽条件下研究了连作对花生幼苗生理特性及荚果产量的影响,结果表明,连作不仅影响植株干物质的积累,同时改变干物质的分配,根冠比增加;连作花生的叶面积、光合速率、叶绿素含量显著降低;连作同时影响磷、钾营养的吸收,但对其在植株中的分配影响不大;花生连作植株主茎高降低,单株结果数减少,荚果产量降低。增施磷钾肥,有利于花生连作的解除。

关 键 词:花生  连作  荚果产量  幼苗  生理

Abstract:Effect of continuous cropping on peanut seedling physiological characteristics and pod yield was conducted with pool trial.The result showed: Continuous cropping significantly decreased the dry weight of peanut plant and increased the translocation of dry material to root.Continuous cropping decreased the leaf area,photosynthesis rate and chlorophyll content;Continuous cropping decreased P and K content in peanut vegetative part,but have little effect on its allocation in peanut vegetative part.When peanut was continuous cropped,its main stem height,the number of pods per plant and pod yield all decreased.Abundant P,K fertilization will be very important for peanut relieving from the effect of continuous cropping.
Keywords:peanut  continuous cropping  pod yield  seedling  physiological characteristics
