在陕西渭北黄土高原地区布设沙棘薪炭林营造技术试验,结果表明该地营造沙棘速生丰产薪炭林宜选择光照充足的梁坡台地,阳坡上下部,峁顶等立地类型;重视做好头年秋季整地蓄墒,适当深栽,砸实土壤,采用植苗造林,春季造林宜早,均能提高造林成活率。为提高抄棘薪炭林产量,造林密度不宜过大,株行距1m×1m者,亩生物量可达1871.3kg。同时,加强沙棘幼林地的抚育管护,做好病虫防治都能提高沙棘造林质量。
The results showed that the planting of seabuckthorn firewood forest in Weibei Loess Plateau of Shaanxi Province had the result of experiment that the fast-growing and high-yielding sapwood of seabuckthorn should be chosen in this area. Soil moisture storage in autumn, appropriate deep planted, smashed solid soil, the use of plantation afforestation, afforestation early spring, can improve afforestation survival rate. In order to increase the yield of poplar firewood, the density of afforestation should not be too large, with the spacing of 1m × 1m and the biomass of mu up to 1871.3kg. At the same time, to strengthen the care and maintenance of seabuckthorn young woodlands, good pest control can improve the quality of seabuckthorn afforestation.
