    摘要:

    以罗平县植烟土壤为研究对象,分析了罗平县土壤有效硼、有效钼含量及其互作与烟叶硼、钼含量的关系。结果表明:(1)罗平县土壤有效硼含量平均值为0.540 mg/kg,变幅为0.051~3.033 mg/kg,变异系数为77.78%;土壤有效钼含量丰富,平均值为0.489 mg/kg,变幅为0~3.458 mg/kg,变异系数高达98.77%。(2)罗平县烟叶硼含量平均值为16.301 mg/kg,变幅为2.163~35.684 mg/kg,符合优质烤烟硼含量范围内的样本数占总数的88.89%;烟叶钼含量偏低,平均值为0.535 mg/kg,变幅为0.059~4.059 mg/kg,符合优质烟叶生长发育钼含量的样本数占总样本数的48.83%。(3)烟叶硼含量与土壤有效硼含量呈极显著正相关,相关系数为0.215,烟叶硼含量(y^)与土壤有效硼含量(x)的回归方程为y^=14.720+2.925x;烟叶钼含量与土壤有效钼含量呈极显著正相关,相关系数为0.411,烟叶钼含量(y^)与土壤有效钼含量(x)的回归方程为y^=0.335+0.409x;(4)土壤有效硼和有效钼的交互作用对烟叶硼含量存在极显著影响,但对烟叶钼含量的影响未达到显著水平。

    Abstract:

    The relationship between the soil available boron and available molybdenum content with the boron and molybdenum content in fluecured tobacco leaf and the relationship between the soil available boron and available molybdenum interaction with the boron and molybdenum content in fluecured tobacco leaf in Luoping tobaccogrowing areas was analyzed.The results indicated that:(1)The soil available boron content in Luoping county ranged from 0.051 to 3.033 mg/kg with the mean of 0.540 mg/kg and the coefficient of variation was 77.78%.The soil available molybdenum content was abundant,which ranged from 0 to 3.458 mg/kg with the mean of 0.489 mg/kg and the coefficient of variation was 98.77%.(2)The boron content in fluecured tobacco leaf in Luoping county ranged from 2.163 to 35.684 mg/kg with the mean of 16.301 mg/kg.The number of samples in the range of high quality fluecured tobacco leaves was 88.89%.The molybdenum content in fluecured tobacco leaf was low,which ranged from 0.059 to 4.059 mg/kg with the mean of 0.535 mg/kg.The number of samples satisfying the growth and development of tobacco leaves was 48.83%.(3)The boron content in fluecured tobacco leaf had high positive correlation with the soil available boron content at 0.01 level.The correlation coefficient was 0.215.Based on the correlation analysis,the regression equation built between soil available boron and the boron content in fluecured tobacco leaf was y^=14.720+2.925x.The molybdenum content in fluecured tobacco leaf had high positive correlation with the soil available molybdenum content at 0.01 level.The correlation coefficient was 0.411.Based on the correlation analysis,the regression equation built between soil available molybdenum and the molybdenum content in fluecured tobacco leaf was y^=0.335+0.409x.(4)As for the content of boron in tobacco leaves,there was a very significant influence by the interaction between available boron and available molybdenum in soil.But the effect of interaction of available boron and available molybdenum in soil on the content of molybdenum in tobacco leaves did not reach a significant level.
