以海南砖红壤为供试土壤,根据作物吸收硒的量来研究施用不同水平的碳酸钙、磷铵、有机质对土壤有效硒的影响.结果表明:在本实验条件下,海南砖红壤中以施用2 g/kg碳酸钙处理植株硒含量增加显著,达到了0.41 mg/kg,砖红壤的有效硒变化显著.%This thesis taking Hainan laterite for the tested soil. According to crop absorption of selenium content to study effects of different levels of calcium carbonate, ammonium phosphate, organic matter of selenium on soil effective. The results showed that on the Hainan laterite soil application of 2 g/kg calcium carbonate was most significantly and plant selenium content was increased 0.41 mg/kg. Effect of selenium of Hainan laterite improved obviously by this experimental condition.
