| 摘 要： | 通过对土壤施沼肥与施猪粪化肥的对比试验,研究了沼肥对大棚草莓土壤理化性质、养分含量及微生物区系的动态影响.试验结果表明:施沼肥土壤可溶性盐含量略呈下降趋势,土壤pH变化不明显,有机质含量略呈下降趋势,土壤速效养分及微生物数量呈上升趋势,有害真菌比例呈下降趋势;施猪粪化肥土壤性质指标变化趋势与施沼肥相同,但较平缓,真菌数量有下降趋势.以上结果为沼气的综合利用提供了理论依据.

| Abstract: | In order to supply a theoretical basis for comprehensive utilization of Biogas.Study on the dynamic influence of the use of Biogas compared with pig manure and fertilizer to the strawberry greenhouse soil was done,about its physical and chemical properties,nutrients and microflora.The result showed that:the content of soluble salt in the soil biogas facilitied are on a slightly downward trend as well as the organic matter.The change of pH is not obvious,but the number of microorganisms and available nutrien... |
