通过大豆盆栽试验,研究几种肥料配比和调理剂施用对不同母质发育的侵蚀红壤的培肥效应.结果表明,1) 与施用NPK化肥相比,土壤调理剂2号的施用可以提高旱地红壤的有效磷和有机质含量,减轻因施用化肥带来的土壤酸化,提高大豆对肥料氮、钾的利用率,增加作物生物量,提高土壤微生物数量;施用有机肥可以较快地提高土壤速效氮、磷、钾和有机质含量,显著提高大豆对肥料氮、磷、钾的利用率和土壤微生物活度,施用有机肥或土壤调理剂是提高红壤旱地肥力较好的技术措施.2) 3种母质发育的红壤相比较,第四纪红土红壤速效养分较高,板岩发育的红壤植物氮磷肥利用率较高,而花岗岩发育的红壤植物钾肥利用率较低,应重...

Effect of 3 fertilization systems in restoring the eroded red soil caused by soil erosion, which is a severely eroded red soil derived from Quaternary Red Clay, granite and slate, were studied with a pot experiment. The results showed that applying soil ameliorant Ⅱ could increase content of available P and organic material compared with applying chemical fertilizer, and also it could alleviate soil acidification and promote the use efficiency of soybean for fertilizer N and K, increase biomass and the number of microbe in soil. Applying organ...
