摘　　要：试验研究了单次滴水量(单次滴水5、10、15、20 mm)对花生全生育期单株绿叶面积、叶绿素含量、单株荚果干重、成熟期根系在不同土层中的分布、成熟期叶片微量元素铁、锌、硼含量及产量的影响。结果表明,在单次滴水5～15 mm区间内,随着单次滴水量的增加,较深土层的根系量增加,叶片微量元素Fe、Zn、B含量、单株荚果干重、单株绿叶面积、叶绿素含量和产量呈增加趋势。但是单次滴水量从15 mm增加到20 mm时,产量变化不明显。建议花生滴灌单次滴水量为15 mm。The effects of water amount of 5,10,15 and 20 mm in simgle drip irrigation on the green leaf area,chlorophyll content and dry pod weight of single plant in the whole growth period,the distribution of roots in different soil layers,and the contents of iron,zinc and boron at maturity stage and the yield were studied in the experiment.The results showed that in the range of 5~15 mm of water amount in single drip irrigation,with the increase of water amount,the root amounts in the deeper soil layer increased,and all the iron,zinc and boron contents,the dry pod weight of single plant,the area of green leaves,the content of chlorophyll and the yield showed increasing trends.However,when the single drip water amount increased from 15 mm to 20 mm,the yield change was not obvious.It was suggested that the water amount of single drip irrigation for peanut should be 15 mm.
