试验结果表明，用杉木优良家系实生苗造林和用第３代扦插苗造林，二者生长量很接近，７年生时单株材积分别为０．０４５９ｍ３和０．０４６３ｍ３；用杉木不同繁殖代数扦插苗造林，生长差异亦不显著；矮杆采穗圃坚持年年更新老杆换新杆，保持了采穗母株的幼年状态，坚持用其根际萌芽条的扦插苗营造矮杆采穗圃，能有效防止多代扦插繁殖引起的衰退。 The results showed that afforestation with excellent Chinese fir family seedlings and afforestation with the third generation of cutting seedlings, the growth of both are very close, the annual volume of single-year plantlets were 0.0459m3 and 0.0463m3, respectively; Afforestation, growth difference is not significant; dwarf bar spike nursery adhere to the annual renewal of the new pole to maintain the juvenile spike mother state, stick with its rhizosphere germination of cutting seedlings to create short pole mining garden, Can effectively prevent the multi-generation cutting propagation caused by recession.
