发展薪炭林是尽快解决农村能源有效的途径之一,1983年经对凌源、建平刺槐薪炭林特性的测试表明:刺槐在半干旱地区的阳坡半阳坡薄土层山地生长较快,8年生进入材积速生期,水平根系发达,根幅3×12米~1,产柴量;朝南沟谷地高于半阴半阳坡地;造林后封山育林明显高于不封山育林;采用短周期平茬高于其它采柴方式。刺槐萌芽力强,12年生树平茬后平均每株发萌条9.6根,薪柴含水率较低(湿柴含水29％);易燃,湿柴就可做燃料,热值高于杨、柳树。
The development of firewood forest is one of the effective ways to solve the rural energy problem as soon as possible. The test of the characteristics of firewood in Lingyuan and Jianhua Robinia in 1983 shows that Robinia pseudoacacia grows rapidly in the semi-arid area, 8-year-old into the rapid growth rate of timber, the level of root system developed, the root width of 3 × 12 m ~ 1, the amount of firewood; south ditch valley is higher than the semi-semi-sunny slope; afforestation afforestation was significantly higher than that of non- Higher than other ways of collecting wood. Acacia sprout strong, 12-year-old tree stubble after the average number of sprouts per plant 9.6 root, fuelwood moisture content is low (wet wood moisture 29%); flammable, wet wood can be a fuel, calorific value higher than the Yang, willow.
