摘要:

为探究生物炭对植烟土壤和烤后烟叶产质量的影响,以烤烟品种0110-142和玉米秸秆生物炭为供试材料,开展田间定位试验,共设置了4个处理:生物炭5 t·hm-2(B1)、15 t·hm-2(B2)、25 t·hm-2(B3)和不施生物炭(CK),对土壤养分、烤烟干物质重、烟叶化学成分及经济性状进行测定,以此分析生物炭不同用量对土壤养分及烤烟生长及烟叶品质的影响,并对土壤养分和烤烟经济性状进行相关性分析。结果表明:土壤有机碳含量因生物炭的增施得到提高,B2和B3处理较CK分别显著增加22.76%、30.31%,B2和B3处理均对土壤碱解氮及速效钾积累作用显著;B3处理增加了团棵期烤烟根部的干物质积累量,B2处理增加了现蕾期烤烟叶的干物质积累量;施用生物炭后,上部叶B3处理及下部叶各处理氯含量均显著增加,B2处理下部叶的烟碱含量显著增加35.71%,糖碱比较CK显著降低,中部叶和下部叶的总氮含量显著增加;B2和B3处理还原糖有所减少,烤后烟叶的化学品质有所提升;在经济效益方面,B2处理显著提高了烤烟上中等烟比例及产值,B3处理显著增加了产量。结合相关性分析发现,土壤有机质和速效钾分别与烤后烟叶上等烟率以及产量呈显著正相关。综上,B2及B3处理利于土壤养分和烟株干物质重的积累,同时B2处理利于提高烟叶品质及经济性状,B3处理使产量有所提高,添加生物炭可以改善植烟土壤养分状况及烟叶品质,对烤烟有一定的增产效果。

Abstract:

In order to explore the impact of biochar on tobacco planting soil and the yield and quality of cured tobacco leaves, the flue-cured tobacco variety 0110-142 and corn stalk biochar were used as test materials to carry out field positioning experiments. Four treatments were set up, with biochar 5 t·hm-2 (B1), biochar 15 t·hm-2 (B2), biochar 25 t·hm-2 (B3) and no application of biochar (CK), which were used to measure soil nutrients, dry matter weight of flue-cured tobacco, chemical composition and economic properties of tobacco leaves, so as to analyze the effects of different amounts of biochar on soil nutrients, growth and quality of flue-cured tobacco, and conduct correlation analysis between soil nutrients and economic traits of flue-cured tobacco. The results showed that the content of soil organic carbon would be increased by increasing the application rate of biochar, and B2 and B3 treatments significantly increased by 22.76% and 30.31% compared with CK; B3 treatment increased the dry matter accumulation in the roots of flue-cured tobacco during the cluster stage, while B2 treatment increased the dry matter accumulation in the leaves of flue-cured tobacco during the budding stage. After the application of biochar, the chlorine content in the upper leaves of B3 treatment and the lower leaves of each treatment significantly increased, the nicotine content in the lower leaves of B2 treatment significantly increased by 35.71%, the sugar and alkali content significantly decreased compared with CK, and the total nitrogen content in the middle and lower leaves significantly increased; B2 and B3 treatments reduced reducing sugar, and the chemical quality of flue-cured tobacco increased. In terms of economic benefits, B2 treatment significantly increased the proportion and output value of medium tobacco in flue-cured tobacco, while B3 treatment significantly increased yield. Combined with the correlation analysis, it was found that soil organic matter and available potassium were significantly positively correlated with the superior tobacco rate and yield of flue-cured tobacco leaves, respectively. To sum up, B2 and B3 treatments were conducive to the accumulation of soil nutrients and dry matter weight of tobacco plants. At the same time, B2 treatment was conducive to improving the quality and economic properties of tobacco leaves and B3 treatment improved the yield. The application of biochar can improve the soil nutrient status of tobacco planting and the quality of tobacco leaves, which has a certain effect on increasing the yield of flue-cured tobacco.
