中文摘要:
      钢渣富含硅、钙等养分,是优良的土壤调理剂原料,但其肥效和合理施用量在很大程度上取决于钢渣的养分含量和组分,本研究选取白色钢渣调理剂(W)和黄色钢渣调理剂(Y)2种性质不同的钢渣调理剂,通过盆栽试验研究其不同施用量(W调理剂0.74、1.47、2.94、5.88 g·kg-1和11.76 g·kg-1;Y调理剂1.47、2.94、5.88、11.76 g·kg-1和23.52 g·kg-1)对水稻生长的影响。研究结果表明,与单施NPK相比,添加W调理剂对水稻生长无显著促进作用,而Y调理剂施用量为11.76 g·kg-1和23.52 g·kg-1时可提高晚稻籽粒产量20%,且当Y调理剂施用量为5.88~23.52 g·kg-1时显著提高晚稻秸秆产量24.02%~35.23%。施用Y调理剂促进了晚稻对氮、磷、钾素的吸收,提高幅度分别为12.61%~21.55%、7.63%~38.31%、11.89%~54.13%。综合结果表明,在弱酸性水稻土(pH 6.51)上,添加W钢渣源调理剂未促进水稻生长,而施用Y调理剂对晚稻生长和氮磷钾养分吸收具有一定的促进作用。
英文摘要:
      A pot experiment was conducted to investigate the effects of two soil amendments(W and Y) derived from steel slag and their application rates(0.74, 1.47, 2.94, 5.88 g·kg-1 and 11.76 g·kg-1 for W; 1.47, 2.94, 5.88, 11.76 g·kg-1 and 23.52 g·kg-1 for Y) on rice growth. The results showed that no significant change in rice yield was found following W amendments; conversely, a 20% increase in rice yield was observed following Y amendments at rates of 11.76 g·kg-1 and 23.52 g·kg-1 as compared with NPK treatments. Y amendment at rates of 5.88~23.52 g·kg-1 increased straw mass by 24.02%~35.23% when compared with NPK treatments. Combined application of Y amendments and NPK fertilizers increased subsequent N, P and K uptake by rice by 12.61%~21.55%, 7.63%~38.31% and 11.89%~54.13%, respectively. The results indicated Y amendments could effectively accelerate subsequent rice growth at high application rates by increasing nutrient uptake in the soil studied(pH 6.51); Conversely, we observed no significant effects with W amendments.
