摘要
香桂作为筠连县特有的经济树种,以其`市场稳定、效益显著而在全县石灰岩地区得到大面积发展,但因种苗短缺而制约了发展速度。本试验通过不同枝条、不同扦插季节及激素处理等方法进行随机区组对比试验,筛选出香桂最佳扦插季节是初夏的5月,枝条是达半木质化的当年生枝条,扦插成活率可达95.2%,且扦插具有繁殖速度快、保持母本的优良遗传特性、成本低等优点。目前该技术已在我县得到大面积推广应用。
Cinnamomum petrophilum,as a unique economic tree species in Junlian County,with its market stability,remarkable economic benefits got a large-scale development in limestone areas in the County,but seed shortages restricted the pace of its development.Different branches,different cutting seasons and hormone treatment methods were used for conducting random block comparison tests,and the results showed that the best cutting season was May in early summer,the branches were half-lignificated branches,the cutting survival rate could reach 95.2%,and the cuttings had advantages of a quick propagation speed,and the excellent genetic characteristics of the parent tree and a low cost.At present,this technology has been extended and applicated in Julian County.
