野生樟树抢救性移栽及年龄快速测定研究

在反季节里,对宜春市南门工业园区内大量野生樟树进行抢救性的裸根移栽及快速测定它们的年龄。结果表明:1)对野生樟树移栽时间愈长,对其成活愈不利,反之则成活率愈高;2)采取裸根近距离移栽,快速地修枝,黄心土培植,浅栽高培土,施钙镁磷肥,生根粉配成泥浆涂抹根部,并做到随挖、随运、随栽、随养,这都是提高野生樟树抢救性移栽成活率关键措施;3)利用树木的年轮数与胸径呈正相关关系,得到的年龄预测模型拟合效果较好,大量野生大樟树的年龄测定可快速求算;4)2次裸根移栽的成本价仅为带土球移栽的72.3%,直接节省移栽费用6.7万多元,裸根移栽的数量越多,价格优势越加明显。

Study on Eco-systems Transplanting and Age Rapid Determination of Wild Cinnamomum camphora

Large numbers of wild Cinnamomum camphora in the south gate industrial zone were made with bare roots transplanting and rapid determination of their age in off-season.Results indicated that the longer transplanting time,the more adverse survived for wild C.camphora,otherwise,the higher the survival rate.Taking bare roots transplanting closely,pruning branches quickly,cultivating loess,planting shallowly and making soil h up high,applying fertilizer with Ca,Mg and P,root stimulate made up with mud daub roots,which were the keys to measures of improving the survival rate of eco-systems transplanting for wild C.camphora.Using tree rings number and the diameter at breast height being positively related,the age prediction model fitting effect was better.Large numbers of wild C.camphora were calculated in short time.Two times of bare root transplanting costing price was only 72.3% of the ball with soil transplant,which directly saved cost $ 67 000 yuan.The more number of bare roots were transplanted,there were more obvious of price advantage.
