马尾松扦插育苗造林配套技术试验

The Assorted Technique Experiment on the Cutting Plant Culture and Afforestation of Pinus massoniana

马尾松扦插造林配套技术试验结果表明：选择优良家系建立采穗圃，采取去梢促萌措施，能使采穗母树平均产穗条２０８条／株；地膜覆盖可使扦插苗生根率提高到８９．７６％，比无地膜覆盖提高１３．４７％；采用切根扦插苗造林，其成活率可达９５．３３％；扦插苗造林比实生苗造林的幼林树高增加２９．６２％，地径增加２８．５７％；通过无性系选优的幼林，１．５年生平均树高达１．３３ｍ。

The results demonstrate that top-lopping to promote sprouting can increase the scions of scion-pluckingmother trees， ground membrane cover can raise the rcoting rate of cutting plants，and the sapling height and grounddiameter of cutting plant afforestation increerse by 29.62 ％ and 28．57 ％ respectively as compared with those ofseedling afforestation.
