【摘要】 对引种在山西省吕梁山国有林管理局上庄油松种子园31年生落叶松种和种源进行调查,通过方差分析得出,不同落叶松种源间胸径、树高生长差异显著。用胸径的平方乘以树高代表不同落叶松种源综合生长因子,大于平均生长指标的种源有11个,从大到小分别为辽宁草河口日本落叶松、辽宁本溪日本落叶松、山西宁武华北落叶松、辽宁清源日本落叶松、河北宽城华北落叶松、河北丰宁华北落叶松、内蒙巴林华北落叶松、山西沁源华北落叶松、辽宁铁岭日本落叶松、山西文水华北落叶松和陕西横山华北落叶松。用胸径的平方乘以树高代表不同落叶松种综合生长因子,日本落叶松生长指标最大,为5 355.98.通过对31年生落叶松不同种的引种试验,以日本落叶松在上庄油松种子园生长表现最好,其次为华北落叶松,长白落叶松、兴安落叶松表现较差。更多还原

【Abstract】 Species and provenance of 31 a introduced Larix gmelinii in Shangzhuang seed orchard,National Forestry Management Bureau of Lvliang Mountain in Shanxi Province were investigated. The results by variance analysis showed difference of DBH and height were significant among different provenance; comprehensive growth factor signed by D2 H,growth index of 11 species was bigger than the average,and the descending order was Liaoning Caohekou Larix kaempferi,Liaoning Benxi Larix kaempferi,Shanxi Ningwu Larix principis-rupprechtii,Liaoning Qingyuan Larix kaempferi,Hebei Kuancheng Larix principis-rupprechtii,Hebei Fengning Larix principis-rupprechtii,Neimeng Balin Larix principis-rupprechtii,Shanxi Qinyuan Larix principis-rupprechtii,Liaoning Tieling Larix kaempferi,Xhanxi Wenshui Larix kaempferi,Shanxi Hengshan Larix kaempferi. Comprihensive growth factor represented by D2 H,of which Larix kaempferi was the biggest of 5 355. 98.The growth of Larix kaempferi in Shangzhuang seed orchard was the best,followed by Larix principis-rupprechtii,and growth of native Larix principis-rupprechtii was better than Larix olgensis and Larix gmelinii.更多还原
