摘　　要：为高效营建光皮桦菌材林提供理论依据,抽样调查在黔西市培育的光皮桦苗木生长表现及造林初步成效。结果表明:5月上旬采种、6月上旬撒播,7月底前移植到无纺布容器中,年终苗木平均地径0.51 cm、苗高74.3 cm,合格苗率达100%;8—9月中旬移植到无纺布容器中,苗木平均地径0.31 cm、苗高27.2 cm,合格苗率达90%。0.5 a生光皮桦容器合格苗出圃规格为地径>0.25 cm,苗高>18 cm;培育裸根苗营造光皮桦菌材林,可有效降低苗木及造林成本。An efficient construction can greatly contribute to the Betula luminifera timber-forest for edible fungus.In this study,a systematic investigation was carried out to evaluate the growth performance and preliminary afforestation of Betula luminifera seedlings that cultivated in Qianxi City of South China.The results showed that seeds were collected in the first ten days of May,sown in the first ten days of June,and transplanted into non-woven containers before the end of July.The average ground diameter and seedling height of the container seedlings transplanted with non-woven fabric were 0.51 and 74.30 cm,respectively,with the qualified seedling rate of 100%.By contrast,the average ground diameter and height of non-woven container seedlings that transplanted from August to mid-September were 0.31 and 27.20 cm,respectively.The qualified seedling rate was 90%in this case.Therefore,0.5 year old Betula luminifera container was the ground diameter>0.25 cm and the seedling height>18 cm.Anyway,the bare-root seedlings and Betula luminifera timber-forest for edible fungus can be expected to effectively reduce the cost of seedlings and afforestation.
