本文通过田间试验,研究了烟草废弃物有机肥与化肥配施对玉米生育期内土壤微生物和土壤酶的影响,试验结果表明:烟草废弃物型有机肥与化肥配施能够提高土壤可培养微生物的数量和土壤微生物量C、N的含量以及土壤酶的活性.以可培养微生物数量最多的抽雄期为例,三种有机无机肥配施处理与纯化肥处理处理相比,土壤可培养细菌数量分别提高11.64%、13.02%和16.98,土壤可培养真菌数量分别提高4.82%、3.28%和5.77%,土壤可培养放线菌数量分别提高13.43%、9.64%和11.55%,土壤可培养固氮菌数量则分别提高1.48%、2.92%和0.41%,土壤微生物量C分别提高0.72%、1.20%和1.21%,土壤微生物量N分别提高2.61%、4.00%、3.22%;在土壤酶活性最高的吐丝期,三种有机无机肥配施处理比纯化肥处理土壤脲酶活性分别提高7.74%、9.02%和3.91%,土壤过氧化氢酶活性分别提高6.20%、43.28%和-7.85%,土壤酸性磷酸酶活性分别提高4.48%、5.03%和5.35%.综合各时期各指标,三种有机无机肥处理以处理M2(烟草废弃物型有机肥代替10%的化学纯氮)表现较优.

Through field experiment,this paper studied the tobacco waste organic manure and NPK chemical fertilizer on maize growth period,soil microorganism and soil enzyme and the effect of the test results show that the type of organic manure and NPK fertilizers can improve tobacco waste soil culturable microorganism quantity and soil microbial biomass C and N content and the activity of soil enzymes.To culturable microorganisms the largest number of tasseling stage,for example,three kinds of organic and inorganic fertilizer treatment compared with the pure fertilizer processing treatment,soil culturable bacteria number increased by 11.64%,13.02% and 16.98 respectively,soil culturable fungi amount is increased by 4.82%,3.28% and 5.77%,respectively,soil culturable actinomycetes number increased by 13.43%,9.64% and 11.55%,respectively,soil culturable azotobacter number is increased by 1.48%,2.92% and 0.41%,respectively,soil microbial biomass C increased by 0.72%,1.20% and 1.21%,respectively,soil microbial biomass N were increased by 2.61%,4.00%,2.61%; On soil enzyme activity of the highest spinning stage,the three kinds of organic and inorganic fertilizer treatment than pure fertilizer soil urease activity increased by 7.74%,9.02% and 3.91%,respectively,soil catalase activity increased by 6.20%,43.28% and 7.85% respectively,soil acid phosphatase activity increased by 4.48%,5.03% and 4.48% respectively.Each period index,three kinds of organic and inorganic fertilizer treatment to M2 (tobacco waste type organic fertilizer instead of 10% pure nitrogen chemicals) has a better performance.
