采用日本落叶松35个无性系苗木,另加2a混系扦插苗、2a实生苗、2a实生换床苗及长岭岗林场种子园2a实生苗进行造林试验,以早期选择出适应性强的无性系进行无性系造林并加以推广。试验方法采用完全随机区组排列,5次重复,每重复2排40个小区;小区设置为4株,造林规格2m×2m。7a生长调查结果表明：在胸径、树高生长方面有极显著性差异,以长岭岗林场种子园2a实生苗、高岩子林场2a混系扦插苗生长最好。
採用日本落葉鬆35箇無性繫苗木,另加2a混繫扢插苗、2a實生苗、2a實生換床苗及長嶺崗林場種子園2a實生苗進行造林試驗,以早期選擇齣適應性彊的無性繫進行無性繫造林併加以推廣。試驗方法採用完全隨機區組排列,5次重複,每重複2排40箇小區;小區設置為4株,造林規格2m×2m。7a生長調查結果錶明：在胸徑、樹高生長方麵有極顯著性差異,以長嶺崗林場種子園2a實生苗、高巖子林場2a混繫扢插苗生長最好。

Using 35 clonal seedlings,with mixed line cutting seedlings and transplanting seedlingsand seedlings in Changling Forest Seed Orchard of two ages were planted,which clonal planted in extension of early chose adaptable clones.Test method was adopted by a completely randomized block arrangement,repeated 5 times,each repeated 2 row of 40 subcompartments,the arrangement for four,planting density 2 m× 2 m,and 7-year old survey results showed that growth was significantly in DBH and height.the best growth for two ages seedlings in Changlinggang Forest Seed Orchard,and two ages mixed line cutting seedlings in Gaoyanzi Forest Station.
