| 摘 要： | 分析了花生的养分积累及分配变化规律。结果表明,花生总干物质量、养分积累量除钙、镁在荚果膨大期最大外其余均随生育进程而增加,至收获期达到最大。每生产100 kg荚果,花生带走氮3.63 kg,磷0.47kg,钾1.45 kg,钙0.90 kg,镁1.00 kg,铁1.38 kg,铜0.02 kg,锌0.26 kg,硼0.05 kg。开花下针期是花生养分积累的关键时期。开花下针期后,花生除钙、镁外的营养元素主要从叶片和茎向荚果逐渐转移,根系分配变化较小。

| Abstract: | The rules of nutrient accumulation and distribution of peanut(Arachis hypogaea) were studied.The results indicated that the dry matter yield and nutrient accumulation increased with the growth of peanut plant and arrived to the maximum in harvest stage;But the accumulation of Ca and Mg reached the peak in pod enlargement time.When every 100 kg pod of peanut were produced,the uptake amount of N,P,K,Ca,Mg,Fe,Cu,Zn and B were 3.63,0.47,1.45,0.90,1.00,1.38,0.02,0.26 and 0.05 kg.The flower and needle stage was the main period of nutrient accumulation.After resettling stage,the nutrient transferred from leaf and stem to pod,and the variation in root was small. |
