Abstract: Xerothermic valley of Yuanmou County is one of the districts that areextremely deficient in energy resources in the countryside of Yunnan Province.For thepurpose of increasing energy resources and renewing forests,a trial of fuelwood forestwas conducted in 1991~1995.A result of the trial shows that cultivation technique forfuelwood forest consists of six measures,i.e, (1)soil preparation:ditch or pit (depth40 cm,diameter 50 cm); (2)density:Eucalyptus plants 5 000/hm²,other plants 10 000/hm²; (3)planting season:during the Summer Solstice to Great Heat; (4)plan-ted wich container seedlings; (5)method of planting:planted with container seedlingsthat were exptinged plastic coating to choose the date of saturating,or within 3 days af-ter rainning; (6)shield:spot sowing Cajanus cajan in spacing.According to the measures,the biomass overground of fuelwood forest is all over 9.0t/hm² from Eucalyptus camaldulensis,E.camaldulensis var.that-landensis,E.citriordora,E.exserta,Leucaena leucocephala,Acacia suma after planting for 3 years.In the first rotation,gross output value is RMB 2 600 yuan/hm² at the local market price.After deductingcosts,the income was more than 2200 yuan/hm².The share of labour is 9.5yuans/man-day.Therefore,it suggests that the fuelwood forest is placed in a projectof ecological and economic construction,and is spread in other xerothermic valleys inYunnan Pfovince.
