摘　　要：为了探究培土厚度与油茶叶片抗寒性的关系,以2013年造林的“大别山1号油茶”为试验材料,比较不同培土厚度下土壤物理性质、油茶叶片解剖结构、相对含水量等生理指标的差异。结果显示,土壤含水量和土壤温度均与培土厚度呈正相关;CK处理海绵组织厚度别是T1、T2、T3处理的1.25倍、1.20倍、1.16倍;T1、T2、T3处理油茶叶片相对含水量分别比CK低3.30%、9.74%和5.51%。因此,培土厚度为15~25 cm可显著提高油茶的抗寒性,可作为油茶抗寒性的栽培技术措施。In order to investigate the relationship between the optimal earth-planting thickness and cold resistance.“Dabie Mountain No.1 Camellia oleifera”trees planted in 2013 were selected as experimental materials to compare the difference of cold resistance indexes such as soil physical properties,leaf anatomical structure,relative water content and relative electrical conductivity under different soil thicknesses.The results showed that both the soil water content and the soil temperature were positively correlated with the cultivated soil thickness.The average of the sponge tissue thickness of processing CK was 1.25,1.20 and 1.16 times of processing T1,processing T2,processing T3,respectively.The relative water content of leaves was 3.30%(Processing T1),9.74%(Processing T2)and 5.51%(Processing T3)lower than that of processing CK,respectively.Therefore,the cultivation of the soil thickness of 15-25cm can significantly enhance the cold resistance of C.oleifera,which can be used as the cultivation technical measure for the cold resistance of C.oleifera.
