摘要
以棕壤为供试土壤进行施用钙素的盆栽试验结果表明，与对照相比，每公斤土施钙２００ｍｇ和８００ｍｇ时，花生分别增产４５％和５２％；每公斤土施钙２００ｍｇ的处理花生果仁中蛋白质含量较对照增加７．１％，从经济高效施肥观点出发，该处理较好。在花生开花下针期以前，每日单株吸钙量逐渐增加，而生育后期呈下降趋势。在苗期花生植株地上部含有的钙元素占整个植株体的比率较高，开花下针期居中，成熟期偏少一些。
The effects of Ca rates on yield, quality and accumulatiton of or in plants of peanut were studied underpot culture condition. The resultS showed that 200mg Caperg soil increased pod yield of peanut. by 45% and proteincontent of kernel by 7.1%. Calcium application can increase Ca uptake by peanat plant. The aborbed Ca ismainly distributed in stem and leaf. 200mg Caperg soil was suitable for growing peanuts in pot culture condition.
