| 摘 要： | 采用盆栽试验,研究了沼渣肥用量对黄瓜不同生育时期生长情况和土壤中细菌、真菌两种微生物数量的影响。结果表明,不同添加量的沼渣肥都能够显著促进黄瓜生长,其中以5.0%沼渣的综合应用效果最好,该处理对黄瓜收获期的根重、地上部重、植株干重、株高、叶数和茎粗分别比未施肥对照组高130.51%,141.87%,72.88%,26.70%,39.32%和35.11%。沼渣肥的施用也显著改变了土壤中微生物的数量,使土壤中细菌数量增加、真菌数量降低,对生育前期土壤微生物的数量影响很大,随着生育期的延长而逐渐降低。土壤中微生物含量与黄瓜生物量相关性分析表明,土壤细菌数与黄瓜生物量成正相关,土壤真菌数量与黄瓜生物量成负相关。田间试验表明,施用沼渣比常规处理产量增加8.3%,比空白对照增产19.2%。

| Abstract: | The pot experiment was conducted to study the effect of different dosage of biogas residue application on the growth and the soil microorganism of cucumber.The results indicated that the addition of biogas residue could affect the cucumber growth at different growth developmental stage.The treatment with 5.0% biogas residue had the best promoting effect on the growth of cucumber.The treatment with the dosage of biogas residue under 5.0%,the addition of biogas residue can increase the fresh weight of the roo... |
