利用盆栽试验方法,研究了几种肥料配比和调理剂施用对侵蚀红壤的培肥效应.结果表明:土壤调理剂2号的施用与施用NPK化肥相比可以提高旱地红壤的有效磷含量,减轻因施用化肥带来的土壤酸化,提高大豆和油菜对肥料磷、钾的利用率,增加作物生物量,且对土壤好气性细菌、真菌和硝化细菌数量具有明显的促进作用.施用有机肥可以较快地提高土壤速效钾和有机质含量,与施用化肥相比显著提高了大豆和油菜对肥料氮、磷、钾的利用率,施用有机肥或土壤调理剂2号的施肥措施是提高红壤旱地肥力的较好的施肥方法.因豆科植物具有根瘤菌共生固氮作用,大豆种植生物量大,肥料利用率高,选取大豆作为先锋物种,可较好地提高...

Effect of 6 fertilization systems in restoring the eroded red soil caused by soil erosion, which is a severely eroded red soil derived from Quaternary Red Clay, were studied with a pot experiment. The results showed that applying soil ameliorant Ⅱ could increase content of available P compared with appling chemical fertilizer, and also it could alleviate soil acidification and promote the use efficiency of soybean and rape for fertilizer P and K. Applying organic fertilizer can increase the content of available K and organic material, while it...
