本研究针对南方花生产区春夏湿涝害,通过盆栽试验研究了湿涝及其营养调控对花生营养吸收的影响.结果表明,1)湿涝时花生对N、P、K和Ca、Mg的吸收和积累严重受抑.N、P、K、Ca总体以叶片下降最明显,其次是根系,茎秆相对下降较小.Mg以茎秆下降最多,其次是叶片,根系相对下降最小.湿涝对花269主要营养元素积累总量的影响大于豫花15号;2)几种营养调控措施对受湿涝后花生的N、P、K和Ca、Mg的吸收和积累几乎均有一定程度的提高.其中含有氮组分的调控处理效果明显,追施磷肥后期可较好的促进花生营养吸收,但效应较迟缓,其余调控处理提高幅度较小.花生叶片中N的积累量和幼果中Ca的积累量与产量之间显著正相关...

This study was mainly aimed at the damage caused by waterlogging in peanut production regions in south of China during spring and summer seasons. With pot experiment, effects of waterlogging and its different nutrition regulations on the nutrient ab sorption and growth of peanut was studied. The main results were as follows： 1） Under the condition of waterlogging, the peanut was serious restrained in absorption and accumulation of N, P, K, Ca and Mg. The total amounts of N, P, K and Ca elements in leaves decreased the most obviously. The chan...
