试验采用密度、品种、土壤培肥３因素裂区设计，对试验因素各生长指标进行方差分析及ＬＳＤ检验．试验林在计算机精确造材基础上进行产量及经济效益分析．８年研究结果表明：辽宁杨树造纸用材林品种应选择辽宁杨等早期速生、制浆性能优良的美洲黑杨及欧美杨良种；栽培密度确定为１６６７～１１１１株／ｈｍ２；１６６７株／ｈｍ２密度轮伐期确定为６年，１１１１株／ｈｍ２密度轮伐期确定为７～８年
The experiment used density, variety, soil fertility three-factor split design, the growth factors of the experimental factors were analyzed by variance and LSD test. Experimental forest in the computer based on accurate production of materials and economic benefits analysis. The results of 8 years showed that: Poplar wood species in Liaoning province should choose Populus deltoides Populus and Populus euphratica with good early pulping and high pulping properties, such as Liaoning Poplar, planting density of 1667 ~ 1111 plants / hm2 and 1667 plants / hm2 density wheel The cutting period was determined to be 6 years, and the density rotation period of 1111 plants / hm2 was determined to be 7 to 8 years
