【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 available boron, available molybdenum content and their interaction with boron and molybdenum content in tobacco leaves in Luoping County was analyzed. The results showed that the average content of available boron in Luoping County was 0.540 mg / kg, the range was 0.051 ~ 3.033 mg / kg, the coefficient of variation was 77.78 mg / kg, and the soil was rich in available molybdenum. The average value is 0.489 mg / kg, the variation range is 0 ~ 3.458 mg / kg, and the coefficient of variation is as high as 98.77 mg / kg.) the average boron content of tobacco leaves in Luoping County is 16.301 mg / kg, and the variation range is 2.1633 ~ 35.684 mg / kg. The number of samples within the range of boron content of high quality flue-cured tobacco is 88.89%, and the molybdenum content of tobacco leaves is relatively low. The average value was 0.535 mg / kg and the variation was 0.059 ~ 4.059 mg / kg. The number of samples that accord with the content of molybdenum in the growth and development of high quality tobacco leaves accounted for 48.833% of the total samples.) the content of boron in tobacco leaves was significantly positively correlated with the content of available boron in soil. The regression equation of the correlation coefficient is 0.215, and the regression equation between the content of boron in tobacco leaves and the content of available boron in soil is y ^ 14. 7202.925x.The molybdenum content of tobacco leaves has a very significant positive correlation with the content of available molybdenum in soil. The correlation coefficient was 0.411, and the regression equation between molybdenum content in tobacco leaves and available molybdenum content in soil was y ^ 0.335 0.409 x ~ (4). The interaction between available boron and available molybdenum in soil had a significant effect on boron content in tobacco leaves, but the effect on molybdenum content in tobacco leaves was not significant.
