摘  要：
以漯河市具有代表性的临颍、舞阳和郾城3个烟区的91个土壤样品及对应的烤后烟叶样品为材料,研究了漯河烟区土壤速效钾含量的数量特征及其与烤烟外观质量各指标间的关系。结果表明:漯河烟区土壤速效钾含量处于46.46~248.07 mg/kg范围内,平均112.51 mg/kg,其中有67.03%集中在低水平,处于适中的占8.79%,仅有1.10%处于高水平,土壤速效钾含量明显偏低。其中,郾城烟区的土壤速效钾含量最低,平均仅为92.20 mg/kg;舞阳烟区的最高,均值为126.80 mg/kg。在漯河烟区烤烟的外观质量各指标中,叶片结构的得分最高,平均8.59分,其次为叶片颜色和身份,叶片色度得分最低,仅为4.69分。土壤速效钾含量与叶片的颜色、成熟度、身份、油分以及外观质量总分之间呈极显著的正相关关系,相关系数分别为0.8079、0.4458、0.6466、0.4551和0.7474,与叶片的结构、色度和正反色差之间虽也存在一定的正相关,但并未达到显著水平。

摘  要：
On the basis of 91 soil samples and corresponding baked tobacco leaf samples in three representative tobacco- growing areas( Linying,Wuyang and Yancheng) of Luohe city,the quantitative characteristics of soil available potassium content as well as the relationships between soil available potassium content and appearance quality of flue- cured tobacco were analyzed through descriptive statistical analysis and correlation analysis. The results indicated that the soil available potassium content of Luohe ranged from 46. 46 mg / kg to 248. 07 mg / kg,and the average content was 112. 51 mg / kg. Among all the tested soil samples,67. 03% had low- level potassium content( 80 ~ 160 mg / kg),8. 79% had moderate content( 160 ~ 240 mg / kg),and only1. 10% possessed high- level content( 240 ~ 350 mg / kg). Among the three main tobacco- growing areas,the soil available potassium content of Yancheng was the lowest,being 92. 20 mg / kg in an average; that of Wuyang was the highest with an average of126. 80 mg / kg. Among all the appearance quality indexes of flue- cured tobacco in Luohe,the average score( 8. 59) of leaf structure was the highest,followed by that of leaf color and leaf body; the color intensity of leaf got the lowest average score( only4. 69). The soil available potassium content was highly significantly positively correlated with the leaf color,maturity,body,oil content and the total score of appearance quality,with the correlation coefficients 0. 8079,0. 4458,0. 6466,0. 4551 and 0. 7474 separately. Although there were certain positive correlations between the soil available potassium content and the leaf structure,color intensity and front- back color difference,these relationships were not significant.
