| 摘 要： | 包气带土层的反硝化作用影响因素复杂,目前尚无较好的反硝化强度测定方法.本文经比较,选择以"地中渗透土层加底物消失平衡法"为参照,改进为向构建的田间渗透箱(柱)原状土层施入一定的硝态氮液态肥料,并配合同步测试土壤的有机氮矿化量、微生物固持无机氮量以及氮挥发量、作物吸收氮值等,再与土层的硝态氮净输入量、本底量、末期量及铵氮...

| Abstract: | The impact factor of denitrification of vadose zone soil is complex.Currently there is no good method to be applied directly to measuring the denitrification strength.After comparing a variety of relevant methods,this paper chose to increase the permeability of soil substrate disappearance balance method as a guide and tried to use the way of applying a certain nitrate liquid manure to the situ permeability soil box of the field,with the simultaneous test of soil organic nitrogen mineralization,microbial r... |
