Shuitu Baochi Xuebao, 2008 根据金沙江干热河谷元谋地区红土层非常发育的裂隙现象,对该地区典型区土壤裂隙形成的环境和土壤剖面进行了调查,并采样进行相关土壤理化性质测定、粘土矿物X-射线衍射分析以及土壤微形态研究。结果表明:(1)该区旱季丰富的土壤裂隙形成与该区主要分布的第四系古红土层(QS)和第四系元谋组的黄棕色土层(QY)等红土母质特性有密切关系;(2)由于土壤裂隙非常发育,成为了边坡崩塌和直接产生重力侵蚀的成因,加剧了土壤侵蚀过程,导致了土柱和土林等强侵蚀景观形成。研究表明 ...

Shuitu Baochi Xuebao, 2011 采用室内人工降雨模拟试验的方法,对不同土壤前期含水量的棕壤坡耕地养分流失特征进行了实验研究.研究结果表明:土壤前期含水量低于20%时,土壤硝态氮主要是以淋溶的形式流失;高于这一含水量时,土壤硝态氮流失途径除了淋失外,还存在径流流失现象.径流中磷离子和钾离子浓度随着降雨时间的增加逐渐减少,流失量与前期含水量不呈线性关系,而是呈近似抛物线关系,在前期含水量为10%～15%之间存在拐点.通过坡面物质流失量(NO3--N、SEP、DP、K+和产沙量)与前期土壤含水量的二次多项式关系,得到最优前期含水量值为11 ...

Shuitu Baochi Xuebao, 2006 采用室内土柱淋溶模拟试验，研究相当于一年降雨条件下磷肥在棕壤土垂直方向上的淋溶迁移特征及鸡粪、秸秆对磷素迁移转化的影响。结果表明：土壤施肥量与速效磷、迟效态磷增加量呈极显著正相关。相关系数分别是0．99141。，0．99774；水溶性磷、Al—P与土壤速效磷相关性最好，相关系数分别达0．972和0．926，2500mg／kg鸡粪与25mg／kg磷肥配施能降低磷淋溶率，并能极显著提高土壤中速效磷的增加量，相当于单施50mg／kg的磷肥；秸秆与磷肥配合施用在短期内对土壤磷素的有效性影响不大 ...
