福建宁化引种赣石系列油茶品种试验初报

Preliminary study of introducing Gan stone camellia varieties in Fujian

于2012年引进赣石系列油茶品种嫁接苗,进行不同坡向(阴坡、半阳坡、阳坡)、不同坡位(上坡、中坡、下坡)造林对比试验。结果表明:不同坡向的油茶平均地径、平均树高、平均冠幅、保存率无显著差异,结实率达显著差异,以阴坡稍高,半阳坡的生长量次之,阳坡的生长量稍低;不同坡位的油茶平均地径、平均树高、平均冠幅达极显著差异,保存率、结实率无显著差异,以下坡较高,中坡的生长量次之,上坡的生长量最低。

Oil-tea camellia grafted seedlings of Ganstone series were introduced in 2012 to compare the effects of different slopes（shady slope, half sunny slope, and sunny slope）, different slope positions（uphill, midslope, and downhill） on afforestation. There were no significantly differences between average diameter, average tree high, average crown breadth, and survival rate of different slope treatments. Setting percentage got significantly differences. The growth volume in shady slope was higher than that in half sunny and sunny slopes. There were significantly differences between average diameter, average tree high, and average crown breadth of different slope positions. There were no significant differences between survival rate and setting rate. The growth volume in downhill was the highest, followed by that in midslope. And the growth volume in uphill was the lowest.
