为探究施钙与覆膜栽培对花生植株Mg、Fe、Zn营养改善状况,以大籽品种湘花2008和南方典型第四纪红土发育的缺钙酸性红壤为试验材料,设置3个基施钙肥梯度[不施钙(Ca0)、施钙375 kg·hm~(-2)(Ca375)、施钙750 kg·hm~(-2)(Ca750)]和2种栽培方式[露地(OF)、覆膜栽培(PF)],采用土柱栽培,研究施钙与覆膜栽培对植株Mg、Fe、Zn含量,积累及籽仁分配系数的影响。结果表明,增施钙肥明显提高了花生茎秆、根系、果针、籽仁中Mg和Fe含量,其中,Ca750-OF处理较Ca0-OF分别提高19.2%、 10.4%、38.6%、3.1%和21.5%、30.9%、27.5%、20.0%,但显著降低了叶、茎秆、果壳及籽仁中Zn含量。覆膜栽培提高了茎秆、果针、籽仁...

In order to explore the nutrition improvement of Mg,Fe and Zn of peanut in red soil of southern China under calcium deficiency by applying calcium and plastic film mulching cultivation,a large seed variety Xianghua 2008 and the typical red soil of southern China under calcium deficiency were used as the test material for the soil column experiment. Three calcium fertilizer gradients and two kinds of cultivation methods (open field and plastic film cultivation) were used in this experiment including no calcium (Ca0),medium calcium fertilizer (Ca...
