黑杨派新无性系076-28、741-9-1杨栽植管理技术一、生物学特性新无性076-28、741-9-1杨系欧洲黑杨人工杂交选育(即俄罗斯杨与小意杨人工杂交)，该品系为雄株，无飞絮，树皮绿白色、树梢呈深绿色，树干通直圆满，有纵向灰褐色纹，分布较密，树冠呈塔形，冠窄适宜密植。侧枝向上直立，主梢优势明显。叶三角形，叶片平展，着生方式为螺旋向上生长，紧贴主梢干部和侧枝，能充分利用光照而不遮荫、喜光。入冬期木质化充分，耐寒耐旱、耐盐碱。二、主要性能参数1．速生性优。新无性系076-28、741-9-1杨胸径一年生平均生长2.55厘米，树高2.78米，单株材积为0.0384立方米，8年平均胸径26.5厘米，树高22.75米，单株材积0.4014立方米。为同龄小黑杨、群众杨材积的156.5%，成材主伐期为8年，小径用材及纸浆材为2—5年。2．稳定性好。经西北、东北各类型区域种植和推广证明，新无性系076-28、741-9-1杨表现出广泛的适应性和稳产丰产性，育苗成活率达95%。主要生长期在6月下旬至9月中旬，生长量占全年的85%以上，3.抗寒性优。在纬度44°34′—47°37′范围内进行区域性栽培推广，结果表明，新无性系076-28、741-9-1杨没有冻害发生，特别在新疆的乌鲁木齐、额尔齐旗、不尔涞河、阿勒泰等地的大树，均经受了高寒的考验，没有像新疆杨出现冻裂现象(破肚子)，在黑龙江远东的绥滨、富锦、宝清也表现良好。4．材质好。该木材密度0.3848克／立方厘米，纤维长度0.9578毫米，宽22.42微米，壁腔比0.1985，材性指标在杨木纤维要求范围内。该杨冠窄主梢明显，出材利用率高，是优良的造纸、纤维材及板材。5．抗病虫害能力强。该杨对主要的病虫害：黑斑病、灰斑病、烂皮病和春尺蠖、透翅娥等有较强的抗性。6．抗风抗倒伏性优，因该树窄冠速生、叶片呈螺旋生长且木质化好，避免了其遇强风折断、倒伏现象。并且该品种极其抗旱，尤其是在东北、西北风沙大，冬季漫长、寒冷、空气干燥下能充分发挥该树种抗逆性强的优点，是上述两地区建造防护林、退耕还林及速生丰产林的理想树种。三、适生推广范围根据区域试验表明，新无性系076-28、741-9-1杨在黑龙江省中部黑土水土保持区、三江平原地区，以及东部山地浅山区均可推广，在黑土、黑钙土、草甸土、淋溶黑土、江河两岸冲击的沙壤土以及含盐量不超过0.5%的土地均可生长。土壤PH值要求在6.5—8.5。是适宜西北、东北寒冷地区发展的抗寒树种。四、苗木繁育技术新无性系076-28、741-9-1杨生根性能好。无性繁殖容易，皮部不定根含量多，生根快，扦插成活容易，在秋季落叶后，翌年春季萌发前采用1年生苗干或壮龄树1年生充分木质化的健壮枝条剪成12厘米左右的插穗，在4月末进行扦插，扦插前将插穗浸水24—48小时或将萌条插穗沙埋浇水，可提高扦插成活率。育苗可以采用池式扦插和垄作单行扦插、每公顷扦插200株左右，要求插穗与地平平齐，踏实并灌一次透水，苗期及时进行灌水、除草、追肥和病虫害防治，寒区育苗还应注意后期控制其徒长，以免木质化不好，造成冻害等。五、营林技术新无性系076-28、741-9-1杨适宜在气候湿润，水肥条件良好的黑土地、黑钙土或沙壤土中生长，在含盐量为0.5%的盐碱土中生长良好，并能速生丰产，造林主要以1年生壮苗，2根l干或3根2干大苗为主，因其冠窄营造纤维用材林、造纸用材林可采用1米x1米、2米xl米、2米x2米。防护林2米x2米，大径材以2米x4米、4米×4米为宜，并应加强修枝剪杈的后期成林管理，以保证树木干形和生产无节良材的要求。（来源：黑龙江林业2003年第2期）
