    摘要:

    通过盆栽试验,研究了钙镁磷肥与氨基酸叶面肥混施共5种不同调控处理对酸性富硒土壤有效硒、水稻各部位硒含量以及其籽粒有机硒含量的调控效果。试验共分为6个处理:①CK,常规钙镁磷肥用量,0.2 g/kg;②P1,单施低量钙镁磷肥,0.4 g/kg;③P2,单施高量钙镁磷肥,0.6 g/kg;④B,单施氨基酸叶面肥,1 500 ml/hm2;⑤P1+B,单施低量钙镁磷肥并配施氨基酸叶面肥,0.4 g/kg + 1 500 ml/hm2;⑥P2+B,单施高量钙镁磷肥并配施氨基酸叶面肥,0.6 g/kg + 1 500 ml/hm2。结果表明:在无外源硒素添加的前提下,不同调控措施均能有效提高酸性富硒土壤中硒的有效性。高用量的2个处理(P2,P2+B)对提高土壤硒有效性的效果最佳,分别使土壤有效硒的含量提高了43.54 μg/kg和42.16 μg/kg,使水稻籽粒有机硒含量分别相应提高了39.27 μg/kg和28.65 μg/kg,5种处理的增幅均达到了极显著水平(P <0.01)。

    Abstract:

    A pot experiment was carried out to investigate the effects of 5 different treatments of mixed application of calcium magnesium phosphate and aminoacid foliar fertilizer on Se availability in acid Se-rich soil, Se contents in different rice organs, and organic Se in rice grains. 6 treatments were designed: 1)CK,conventional calcium magnesium phosphate, 0.2 g/kg; 2) P1, single low calcium magnesium phosphate, 0.4 g/kg; 3) P2, single high calcium magnesium phosphate, 0.6 g/kg; 4)B, single aminoacid foliar fertilizer; 1 500 ml/hm2; 5) P1+B; 6) P2+B. The results showed that all treatments increased significantly soil Se availability and organic Se contents in rice grains compared with CK (P <0.01), the effects of P2 and P2+B treatments were best, which increased available Se contents by 42.16 μg/kg and 43.54 μg/kg, respectively, increased organic Se contents in rice grains by 28.65 μg/kg and 39.27 μg/kg, respectively.
