云南娑罗双扦插育苗试验

通过3种不同的基质研究云南娑罗双扦插苗的生长情况,为不同营林需要提供合理的育苗方式。研究发现,森林表土35%+珍珠岩65%混合后培育出的扦插苗长势最好,成活率为78%,其他两种基质下云南娑罗双扦插苗的长势较弱,成活率分别为80%(基质三)、83%(基质一),略高于基质二。综合看来,云南娑罗双扦插育苗在3种基质下各有所长,在实际育苗过程中,根据造林需求,科学合理的选择基质。

There are three different matrices research Yunnan Balau growth of cuttings for different silvicultural nursery need to provide a reasonable way. Study found that 35% of forest topsoil ＋ perlite 65% mixed breed of cuttings grow best, the survival rate was 78%, the other two substrates under the Yunnan Balau cuttings growing weaker, the survival rate was 80 （base three）, 83% （matrix a）, the higher the matrix II. Comprehensive view, Yunnan Balau cuttage matrix under the three strengths, in the actual breeding process, according to afforestation needs, scientific and rational selection matrix.
