| 摘 要： | 经过大田试验,研究了不同施肥处理对复垦土壤养分和酶活性的影响,结果表明,不同施肥处理对复垦区土壤养分和酶活性有一定影响。在玉米整个生育时期,化肥(C)、化肥+有机肥(CM)和化肥+有机肥+菌肥(CMB)处理土壤全氮含量分别增加了2%～11%,10%～60%,9%～79%,土壤速效磷含量分别增加42%～53%,64%～76%,71%～80%,土壤速效钾含量分别提高了1%～38%,16%～32%,21%～47%;土壤酶活性也有一定程度的提高,其中以CM和CMB处理提高最大,与不施肥处理差异显著。

| Abstract: | Through a field experiment effect of fertilizer treatments to soil nutrients and enzyme activities in reclamation was studied.The results showed that there are different effects on soil nutrients and enzyme activity of the different fertilizer treatments in core-mining subsidence area.During the whole growth period of maize,the treatment of C,CM and CMB soil total nitrogen content increased by 2% to 11%,10% to 60%,9% to 79%;Available phosphorus content increased by 42% to 53%,64% to 76%,71% to 80%;Soil avai... |
