【摘要】：以羅平縣植煙土壤為研究對(duì)象,分析了羅平縣土壤有效硼、有效鉬含量及其互作與煙葉硼、鉬含量的關(guān)系。結(jié)果表明:(1)羅平縣土壤有效硼含量平均值為0.540 mg/kg,變幅為0.051~3.033 mg/kg,變異系數(shù)為77.78%;土壤有效鉬含量豐富,平均值為0.489 mg/kg,變幅為0~3.458 mg/kg,變異系數(shù)高達(dá)98.77%。(2)羅平縣煙葉硼含量平均值為16.301 mg/kg,變幅為2.163~35.684 mg/kg,符合優(yōu)質(zhì)烤煙硼含量范圍內(nèi)的樣本數(shù)占總數(shù)的88.89%;煙葉鉬含量偏低,平均值為0.535 mg/kg,變幅為0.059~4.059 mg/kg,符合優(yōu)質(zhì)煙葉生長(zhǎng)發(fā)育鉬含量的樣本數(shù)占總樣本數(shù)的48.83%。(3)煙葉硼含量與土壤有效硼含量呈極顯著正相關(guān),相關(guān)系數(shù)為0.215,煙葉硼含量(y^)與土壤有效硼含量(x)的回歸方程為y^=14.720+2.925x;煙葉鉬含量與土壤有效鉬含量呈極顯著正相關(guān),相關(guān)系數(shù)為0.411,煙葉鉬含量(y^)與土壤有效鉬含量(x)的回歸方程為y^=0.335+0.409x;(4)土壤有效硼和有效鉬的交互作用對(duì)煙葉硼含量存在極顯著影響,但對(duì)煙葉鉬含量的影響未達(dá)到顯著水平。
[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.
