摘要:
为评价种植巨菌草对土壤生态环境影响，通过野外采集土样及盆栽试验，比较分析种植巨菌草对土壤微生物数量及酶活性的影响，以期为种植巨菌草的土壤生态效应评价提供科学依据。试验设种植巨菌草2年不同采样时间的处理组5月（NaT）、10月（NbT）、次年1月（NcT）及其对照组（NaK、NbK、NcK）；盆栽试验处理组NpT和对照组NpK，测定并分析采集土样的土壤微生物数量及土壤酶活性。结果表明：种植巨菌草试验区土壤微生物数量及土壤酶活性分析的结果与盆栽试验一致。巨菌草种植各处理组的土壤细菌、真菌、放线菌数量均极显著高于对照组（P<0.01），其中盆栽处理组NpT的土壤微生物数量较对照组增幅最大，细菌、真菌及放线菌数量分别是对照组的5.7、9.6和9.1倍；各处理组的土壤过氧化氢酶、蔗糖酶、脲酶及酸性磷酸酶活性均显著高于对照组（P<0.05），除NbT的土壤酸性磷酸酶活性外，均达极显著水平（P<0.01）。巨菌草的种植提高了土壤微生物数量和土壤酶活性，表明巨菌草种植对于改善土壤质量具有积极作用。
Abstract:
In order to evaluate the effect of planting Pennisetum sp.on soil ecological environment,comparing and analyzing the influence of planting Pennisetum sp.on soil microbial quantity and soil enzyme activity through field and pot experiment,to provide scientific basis for its soil ecological effect.In this experiment,there were the treatment groups NaT,NbT,and NcT of different sampling times (in May,October and January of the following year) by planting Pennisetum sp.for 2 years,with the control groups NaK,NbK and NcK; and pot experiment with the treatment group NpT and the control group NpK,the quantity of soil microorganisms and the activity of soil enzymes were measured and analyzed.The results of soil microbial quantity and soil enzyme activity analysis in the experimental area of planting Pennisetum sp.were consistent with those of pot experiment.The results indicated that the quantity of soil bacteria,fungi,and actinomycetes of the treatment groups by planting Pennisetum sp.were extremely higher than the control groups (P<0.01).The quantity of soil microorganisms in the treatment group of pot experiment increased the most than that in the control group,the quantity of bacteria,fungi and actinomycetes in the treatment group was 5.7,9.6 and 9.1 times as much as that in the control group,respectively.The soil catalase,sucrase,urease,and acid phosphatase activity of the treatment groups were significantly higher than the control groups (P<0.05),in addition to soil acid phosphatase activity of the group Nb,reached extremely significant level (P<0.01).The quantity of soil microorganisms and soil activity were increased by planting Pennisetum sp.,which indicated that the planting of Pennisetum sp.played a positive role in improving soil quality.
