摘 要：
利用不同培肥处理对晋城煤矿采煤塌陷区复垦土壤熟化效果进行研究,结果表明:每个培肥处理施入土壤中氮(N)、磷(P2O5)养分相同时,经过玉米、小麦的轮作后,各培肥处理对复垦土壤(不同年限)熟化有不同的效果。其中,各处理的土壤全氮、全磷、过氧化氢酶、磷酸酶变化差异不显著;土壤速效N、P、有机质、微生物量碳、氮以及转化酶、脲酶增加较为明显。与对照相比,化肥+有机肥+菌肥处理的培肥效果最为显著,速效氮、磷增加了21.8%,25.5%,有机质增加了14.2%,微生物量碳、氮增加了17.2%,14.8%,转化酶、磷酸酶和脲酶的增量分别达到了10.2%,16.0%,25.0%,其余培肥处理的效果为:化肥+有机肥>有机肥>化肥>对照。

摘 要：
The experiment studies the effect of the reclaimed soil around the subsided land resulting from coal-mine by different treatment of application fertilizers in Jincheng.The result shows: when adding the same content of N and P2O5 into soil in every treatment of application,through the rotations between maize and wheat in reclaimed soil(with different reclamation years),every treatment of application is useful to reclaimed soil;The difference of every treatment of soil's total N,P,phosphatase,hydrogen peroxidase is not remarkable,the elevation of available P,alkaline N,O.M,SMB-C,SMB-N,urease,invertase of soil are significant.Compared with CK,the effect of chemical+organic+microbial fertilizer is the best,alkaline N,P increased 21.8%,25.5%,OM increased 14.2%,SMB-C and SMB-N increased 17.2%,14.8%,invertase,phosphatase,urease increased 10.2%,16.0%,25.0%;The effects of other treatments:chemical+organic>organic>chemical>CK.
