| 中文摘要: |
| 以不施肥为对照，研究了化肥、有机肥、沼肥对西红柿土壤微生物数量和土壤呼吸的影响。结果表明：施用化肥土壤的细菌数量比对照减少0.6%～57.2%，真菌数量呈现先增加后减少
的趋势，放线菌数量比对照增加7.4%～65.0%；化肥用量减少一半，土壤的真菌数量增加，放线菌数量减少。施用有机肥土壤的细菌、真菌、放线菌数量比对照分别增加12.1%～160
.8%、5.1%～142.3%、46.2%～157.5%；有机肥用量减少一半，土壤细菌、真菌、放线菌数量分别减少28.0%～87.8%、9.7%～40.3%、21.8%～71.1%。施用沼肥土壤细菌、真菌和放线菌数量与对照相比呈现先增加后减少的趋势。施肥增强了土壤呼吸，其中有机肥增加的幅度最大，为23.5%～118.6%，沼肥次之，为20.8%～38.5%，化肥增加的幅度最小，为10.5%～25.3%。 |

| In solar greenhouse, effect of CK (no fertilization), NP fertilizer, organic manure, biogas fertilizer on soil microorganism and respiration was studied. The results showed that, compared to CK, the number of bacteria of soil decreased by 0.6%～57.2%, fungi of soil increased first and then decreased, and actinomycete of soil increased by 7.4%～65.0% when using NP fertilizer. Application amount of NP fertilizer reduced a half, the number of fungi of soil increased, but actinomycete of soil decreased. By using organic manure, the number of bacteria, fungi
and actinomycete of soil increased by 12.1%～160.8%, 5.1%～142.3% and 46.2%～157.5%. When the application amount of organic manure reduced a half, the number of bacteria, fungi and actinomycete of soil decreased by 28.0%～87.8%, 9.7%～40.3% and 21.8%～71.1%. By applying biogas fertilizer，the numbers of bacteria, fungi and actinomycete increased first and then reduced. Fertilization enhanced soil respiration, the extent of increasing under organic manure was the biggest, wi
th 23.5%～118.6%, and that with biogas fertilizer was 20.8%～38.5%, while that with NP fertilizer was the smallest in all treatments. |
