摘　　要：为探究沼液水肥一体化在林业上的应用效果,研究了沼液水肥一体化对大花序桉幼林生长、林下土壤养分及林下种植的百部、天冬、勃氏甜龙竹生长的影响。结果表明,沼液水肥一体化对大花序桉、百部、天冬、勃氏甜龙竹生长及林下土壤养分有一定影响。山高部、山中部和山底部施沼液处理大花序桉树高分别较不施沼液和水对照高10.59%、13.93%和25.93%,山高部、山中部和山底部施沼液处理大花序桉胸径分别较不施沼液和水对照高17.93%、20.47%和28.32%。施用沼液可提高土壤水解性氮含量、有效磷含量和速效钾含量,能提高土壤肥力。沼液水肥一体化能提高百部和天冬产量,增加勃氏甜龙竹出苗数和出笋量。In order to explore the application effect of biogas slurry combined with water and fertilizer integration on forests,this paper studied the effects of biogas slurry combined with water and fertilizer integration on the growth of young Eucalyptus cloeziana forests,soil nutrients under the forest,and the growth of Stemona japonica,Asparagus cochinchinensis and Dendrocalamus brandisii planted under the forest.The results showed that biogas slurry combined with water and fertilizer integration had a certain effect on the growth of Eucalyptus cloeziana,Stemona japonica,Asparagus cochinchinensis and Dendrocalamus brandisii,as well as the soil nutrients under the forest.The height of Eucalyptus cloeziana treated with biogas slurry in the high,middle,and bottom of the mountain were 10.59%,13.93%,and 25.93% higher than those of the control(no application of biogas slurry and water),respectively.The breast diameter of Eucalyptus cloeziana treated with biogas slurry in the high,middle,and bottom of the mountain were 17.93%,20.47%,and 28.32% higher than those of the control(no application of biogas slurry and water),respectively.The application of biogas slurry could increase the hydrolytic nitrogen content,effective phosphorus content and available potassium content of soil,which could improve soil fertility.The application of biogas slurry combined with water and fertilizer integration could increase the yield of Stemona japonica and Asparagus cochinchinensis,as well as increase the seedlings and shoot quantity of Dendrocalamus brandisii.
