利用伐蔸萌条扦插造林,在我国一些杉木产区已有数百年的历史。在本世纪五十年代对杉木插条造林曾提出过一些争议,加以解放后造林事业迅猛发展,由于伐蔸萌条数量少,又受采伐地区和采伐量的限制,使插条造林发展缓慢。但是,杉木插条林具有生长快,分化小,干形通直圆满,林相整齐等优点。所以,江华瑶胞的集体山,至今仍采用插条造林。为了充分利用插条造林的优越性,适应杉木选育良种工作的需要,自1978年来,我们探索用幼苗促生萌条,在圃地剪萌条培育扦插苗,然后利用扦插苗上山进行造林,现已获得初步成效。一、营建萌条采穗圃
The use of cutting 蔸 sprout cuttings afforestation in some of China fir production area for hundreds of years of history. In the 1950s, some controversies were raised about the afforestation of Cunninghamia lanceolata. After the liberation, the afforestation undertaking developed rapidly. Due to the small number of sprung buds and the limited logging area and logging volume, the afforestation of cuttings was slow. However, Cunninghamia lanceolata forest has the advantages of rapid growth, small differentiation, stem-shaped integrity, straight forest phase and so on. Therefore, the collective mountain of Ganghwa Yao, still using cuttings afforestation. In order to make full use of the superiority of cuttings afforestation and to adapt to the needs of fir seed selection, we have explored the use of seedlings to promote sprouting, cutting cuttings in nursery to cultivate cutting seedlings, and then using cutting seedlings up the mountain for afforestation, Has now achieved initial results. First, the construction of sprouts mining sprouts
